TriSalus Life Sciences, an oncology company integrating novel delivery technology with standard of care therapies to transform treatment for patients with solid tumors, is pleased to announce the launch of the TriNav^® XP Infusion System, the latest advancement in the company’s portfolio of pressure-enabled drug delivery systems designed to improve therapy delivery in varying vascular environments.

Building on the success of the TriNav platform, TriNav XP was engineered specifically for compatibility with larger embolic particles (beads up to and including 700 μm) while maintaining the performance and safety features that Interventional Radiologists require. TriNav XP is designed with a more flexible distal tip for improved trackability, is available in both 130 cm and 150 cm lengths, and is recommended for use in 1.5 mm to 3.5 mm vessels.

TriNav XP incorporates SmartValve^® Technology, which has been shown in multiple studies to more effectively deliver therapies deep within the target anatomy, while reducing non-target delivery to surrounding healthy tissues compared to delivery with a traditional microcatheter^1-3.

“At TriSalus, our goal is to empower physicians with tools that deliver therapy more effectively and consistently,” said Mary Szela, CEO and President of TriSalus Life Sciences. “The TriNav XP Infusion System extends the reach of our Pressure-Enabled Drug Delivery™ approach with our SmartValve Technology, giving clinicians greater flexibility to treat patients in a range of embolization procedures.”

About TriSalus Life Sciences

TriSalus Life Sciences^® is an oncology focused medical technology company seeking to transform outcomes for patients with solid tumors by integrating its innovative delivery technology with standard-of-care therapies. The Company’s platform includes devices that utilize a proprietary drug delivery technology and a clinical stage investigational immunotherapy, nelitolimod, a class C Toll-like receptor 9 agonist, for a range of different therapeutic and technology applications. The Company’s delivery systems employ its proprietary Pressure-Enabled Drug Delivery™ (PEDD) approach to deliver a range of therapeutics: the TriNav® Infusion System for hepatic arterial infusion of liver tumors and the Pancreatic Retrograde Venous Infusion System for pancreatic tumors. The PEDD technology is a novel delivery approach designed to address the anatomic limitations of arterial infusion for the pancreas. The PEDD approach modulates pressure and flow in a manner that delivers more therapeutic to the tumor and is designed to reduce undesired delivery to normal tissue, bringing the potential to improve patient outcomes. Nelitolimod, the Company’s investigational immunotherapeutic candidate, is designed to treat the immunosuppressive environment created by many tumors and which can make current immunotherapies ineffective in the liver and pancreas. The Company is in the final stages of data completion for a number of phase 1 clinical trials and will begin exploring partnership opportunities for development. In partnership with leading cancer centers across the country – and by leveraging deep immuno-oncology expertise and inventive technology development – TriSalus is committed to advancing innovation that improves outcomes for patients.
