Symple Surgical Inc, Renal Sympathetic Denervation, Medical Microwave Ablation Technology and Devices

We are Symple Surgical

Symple Surgical is an exciting start-up Medical Device company focused on developing novel therapeutic technologies through controlled Microwave Ablation. Our technologies are thoughtfully designed to be familiar and easy to use by the operator while providing automated control, feedback, and safety for the patient.

Symple Surgical’s first product offering is the DirectAblate GRIZZLYTM Microwave Ablation SystemTM. Through the ground-breaking therapy of directed microwave ablation of pre-cancerous Barrett’s cells, we are focused on helping millions of patients worldwide living with Barrett’s Esophagus and the subsequent advancement to esophageal adenocarcinoma (EAC). While multiple clinical studies have demonstrated that radiofrequency ablation for treatment of Barrett’s Esophagus is incompletely effective in 25% of patients studied, the novel utilization of a superior microwave ablation mechanism will overcome these difficult to treat patients. This superior mechanism includes more uniform heating, superior automation and control over energy deployment regions, and an antenna that can both emit and receive signals. Thermal ablation has proven to be a safe and effective way to treat Barrett’s Esophagus and EAC utilizing a short one-time minimally invasive gastroenterology procedure.

Due to the unique characteristics of Microwave Energy, wide-ranging applications for this technology cross-over into the fields of Interventional Cardiology, Electrophysiology, Nephrology, Pulmonology and Vascular Intervention. Symple Surgical has established an exciting pipeline of products targeting growing markets in minimally invasive medicine.

Symple Surgical, Inc. is a privately-held company with engineering and product development offices in Sacramento, California and Flagstaff, Arizona. We are comprised of a highly experienced team of Medical Device professionals with global experience covering research and development (R&D) through product commercialization. Company founder and serial entrepreneur, Dan Kasprzyk, has a strong track record with several medical device companies from inception through exit. We are backed by a world class Scientific Advisory Board of clinicians, Mayo Clinic and researches dedicated to developing therapeutic microwave technology for superior treatment of life-threatening chronic conditions.

Our Technology

Circumferential Ablation | Preserved Arterial Surface | Automated Ablation Activation

The Symple Surgical GRIZZLYTM microwave ablation catheter system is a beside-the-scope, over-the-wire, moveable antennae, compliant urethane balloon system. The catheter is a fully automated system that can create complete circumferential and spot ablations from a single device up to 40mm in length. A compliant urethane balloon provides the ability to target esophagus diameters between 18-35mm. Initial product offering will be a beside-the-scope catheter with .035 guidewire compatibility. At the heart of the GRIZZLYTM catheter is a proprietary microwave antenna which paired with the 50W, 18GHz microwave generator delivers precise and uniform microwave energy to the target ablation zone.

A secondary product is the DirectAblate Renal Denervation SystemTM which is a proprietary self-centering internally integrated microwave antenna, real-time surface temperature monitoring, and active arterial wall cooling for safety. A 100 Watt / 2.45 GHz microwave generator with integrated control system provides precise control and data acquisition. DirectAblate Renal Denervation SystemTM has superior catheter and energy delivery technology that effectively delivers a single 90 second circumferential non-contact ablation per renal artery.


Validated Thermal Simulation
Using thermal simulation and laboratory testing, Symple Surgical optimizes the DirectAblate Renal Denervation System™ and delivers therapeutic microwave energy to Sympathetic Nerves.

Through comprehensive thermal simulation and laboratory testing, Symple Surgical has optimized the DirectAblate Renal Denervation SystemTM to deliver therapeutic microwave energy to the site of the Sympathetic Nerves. Figure 1 shows Computer Generated Thermal Simulation data of the DirectAblate Renal Denervation SystemTM. Figure 2 is histological sample of an in vivo study performed with the DirectAblate Renal Denervation SystemTM. The treatment zone is nearly identical in size and shape to the computer based modeling as identified with NBT viability staining (blue/purple coloring is preserved tissue; translucent/white is treated tissue; rings are 1mm spacing).

directed Renal Denervation (dRDN)

The Symple Surgical microwave device is demonstrated within a protein albumin gel highlighting the “doughnut-shape” circumferential ablation zone created. While penetrating 6mm deep in to the protein gel, the test demonstrates the thermal protection of the vessel wall and the 1mm ring of the medial layer. Past the 6mm ablation zone there is a substantial drop-off in temperature, thereby limiting damage to the non-target perivascular structures.

Barrett’s Esophagus and Esophageal Adenocarcinoma
In the United States today over 12 Million American adults live with Barrett's Esophagus and deal with a 30-fold increased risk of developing “EAC”. Pacific Rim countries are dealing with an exponential growth in esophageal squamous cell cancers and the incidence of Barrett’s Esophagus. Although many solid tumor forms of cancer have been positively impacted by diagnostic and therapeutic advances, the path for Esophageal Adenocarcinoma “EAC” has been grim over the past 30 years with over 800% growth in incidence over that time period. It is a frustrating disease for many Gastroenterologists as most patients receive an initial diagnosis of Stage II “EAC” or later. Many studies have reported molecular events in the esophageal squamous epithelium that are triggered by gastroesophageal reflux, “GERD” to cause Barrett’s metaplasia. Until recently, the origin of the cells responsible for the genesis of Barrett’s Esophagus were poorly understood and unidentified. Researchers at Columbia Medical Center recently identified (October 2017) the “cell of origin” through a previously unidentified zone of unique basal progenitor cells.

Hypertension and Resistant Hypertension
In the United States today, 80 million adults are affected by chronic high blood pressure, known as Hypertension, and nearly 1 billion people worldwide. Chronic high blood pressure is linked to heart disease, stroke, kidney disease, and diabetes. The consequences of high blood pressure to domestic and global health are staggering:
  • Heart disease caused by hypertension, is the leading causes of death in U.S and globally
  • Stroke is the fifth leading causes of death domestically and worldwide
  • Hypertension accelerates loss of kidney function in over 500m people worldwide and 26m Americans
  • The global incidence of Hypertension among adults is expected to increase 60% by 2025
More severe resistant Hypertension is defined as blood pressure above optimal range despite the use of maximum tolerated doses of at least three antihypertensive medications including a diuretic. Resistant hypertension prevalence is approximately 5-8% of total adult population. Complications from pharmaceutical therapies create the biggest impact to quality of life in patients with resistant Hypertension.

Why Microwave
Microwave vs. RF Heating
Microwave vs. RF Heating from Symple Surgical Inc. RF Ablation has limited capability compared to Microwave Ablation. Advantages of Microwave Ablation include:
  • Faster Heating
  • Larger Heating Zone
  • More Uniform Heating Zone
  • Less dependent on Tissue Properties
  • No grounding pad or 2nd pole necessary
  • Tissue contact is not necessary
  • Independent of wall pressure
The heating zone is controlled by several factors including: Power, Frequency, Antenna Design, and the material properties in the near-field of the antenna.
Reimbursement Landscape
There is increasing pressure from gastroenterologists to move their procedures out of the hospital into surgical outpatient facilities due to economic incentives. If performed in a hospital setting, the physician gets only the Physician Procedure Fee and is restricted in the number of procedures due to slower turnover rates. Physicians are incentivized to move their procedures to outpatient facilities because they keep the Physician Procedure Fee, plus profit on the facility fee and portion of the anesthesia fee. Additionally, the outpatient facilities accommodate faster turnover, allowing for more procedures.
Beyond Barrett’s
In small pilot studies, Sympathetic Denervation has shown promise in being a beneficial therapy for several life-threatening conditions including:

Overview | Download Investment Opportunity

Symple Surgical, Inc. (the “Company” or “SSI”) was established in 2012 with a vision of providing low-cost, minimally invasive, microwave ablation (“MWA”) technology. In 2016, SSI began its focus on treating Barrett’s Esophagus and Esophageal Adenocarcinoma (“EAC”) due to the potential advantages of MWA over the current standard of care. EAC, as a disease, is the fastest growing solid tumor cancer in the world, and SSI has developed a novel method of ablation using microwave frequencies to safely and effectively ablate Barrett’s Esophagus and subsequently eliminate EAC. This disease state has grown by over 800% over the last 30 years and represents a large market opportunity for new treatment methods.


The Company’s founder, Dan Kasprzyk, is a medical device engineer and serial entrepreneur with a track record of successful start-ups and exits. He has primarily funded the Company with approximately $2.0 million, along with placing relevant intellectual property (IP) into the firm. The Company’s prior rounds of financing have raised approximately $1.7 million in funding beyond that invested by Mr. Kasprzyk. The Company now seeks investors to fund the remaining capital needs for the next significant milestone, proof of concept. This includes prototyping of the GRIZZLY™ catheter, handle automation, antennae prototyping, and pre-clinical studies.


Symple Surgical Inc.

SSI’s microwave ablation method is superior to other ablation methods for treating Barrett’s Esophagus and EAC and provides the following:

  • Larger ablation zone killing commonly missed deeper cells
  • Microwave energy delivery that is independent of target tissue properties and is non-contact
  • Dielectric heating creating a uniform heating method
  • Potential for fewer follow-up procedures and less pain
  • Ability for circumferential and directional ablations from a single device
  • Microwave antennae for monitoring and emission of energy




To date, the Company’s engineering and Scientific Advisors have contributed initial concepts and designs to the Company. Intellectual property reviews were performed prior to forming the Company and eight (8) patent applications associated with the various alternatives have been submitted.


The Company has established initial development plans and timelines for the completion of prototypes, assessment of the alternatives, and starting both animal and FIM studies. SSI’s Management team has significant experience in completing the 510(K) process and successfully commercializing medical products. Below outlines Management’s product rollout plan with an initial focus on outpatient facilities:
