Medical Device Engineering Firm, Engenious Design, partners with Precision Microwave to expand Precision Microwave’s groundbreaking technology.

Prairie Village, KS: Engenious Design has partnered with Manhattan (KS) startup Precision Microwave to develop a technologically-advanced system to treat previously-inoperable cancer tumors with minimally-invasive surgery. The system is a new Microwave (MW) Generator to accompany Precision Microwave’s next-generation Directional Microwave Ablation (DMWA) applicator.

Precision Microwave and Engenious Design are combining Precision’s market-disruptive technology with Engenious Design’s experience in medical device design. Precision Microwave’s DWMA system is a new tool for minimally-invasive thermal ablation treatment of cancers, a novel treatment tool with ability to reduce the risk of unintended injury to vital structures near tumors. The new technology complements existing options for thermal ablation and greatly expands the tools available to surgeons that address challenging cases and broaden the range of cases that could be safely and effectively treated.

Austin Pfannenstiel, Precision Microwave’s founder and CEO, explains, “Engenious Design has been the perfect partner for a small, start-up medical device company like us. I have been consistently impressed by their team’s tremendous depth of knowledge and experience spanning technical & industrial design, clinical insight, and regulatory considerations, which has enabled us to stay focused on leveraging our own strengths while making significant progress towards commercialization. Importantly, Engenious Design has always been very considerate of the resource constraints faced by a small smart-up and has been invaluable in helping us identify and accomplish milestones that add maximum value.”

Precision Microwave’s system was recently granted a key patent protecting the unique, directional ablation technology. Precision Microwave’s regulatory strategy also employs a faster and lower-risk path to FDA clearance by leveraging predicate devices. Precision Microwave has already received $1.2 MM in grant funding from the National Science Foundation (NSF), and are working to close additional funds to pursue FDA clearance and commercialization.

Chris Justice, Principal at Engenious Design, adds, “Most of us have been affected by cancer through family, friends or our own experience, and we are delighted to help Precision Microwave create better tools to fight cancer. Precision Microwave’s technology is truly innovative and works to provide more precise control to surgeons; control that allows targeting of cancers and preservation of adjacent vital structures. The Precision Microwave team has developed technology that is a game-changer in cancer therapy and we are excited to partner and bring this technology to market quickly.”

About Precision Microwave: Manhattan, Kansas based, Precision Microwave is a startup medical device company focused on developing new thermal ablation technologies that can expand patient access to minimally invasive treatments. Precision Microwave (PM) was founded in 2017 by Austin Pfannenstiel, PhD, MBA, after the PM team successfully completed a National Science Foundation (NSF) Innovation Corps (I-Corps) program and identified a major clinical need to commercialize directional microwave ablation technology originally invented at Kansas State University. Precision Microwave has since been awarded a National Science Foundation (NSF) Small Business Technology Transfer (STTR) phase I and a Small Business Innovation Research (SBIR) Phase II grant totaling over $1.2MM. Austin’s R&D experience includes 6+ years developing novel microwave technologies for precise, image-guided thermal ablation of cancer and he is a co-author on one granted patent and three patent applications in the field. He also spent seven years in the US Navy as a submarine officer and nuclear power instructor and continues to serve in the US Navy Reserve. Precision Microwave maintains close collaborative relationships with a network of physicians specialized in thermal ablation procedures as well as the Kansas State University Colleges of Engineering and Veterinary Medicine.
