Drug Delivery Technology

The TriSalus™ drug delivery devices utilize the proprietary Pressure-Enabled Drug Delivery™ (PEDD™) method to overcome intratumoral pressure through modulation of pressure and flow to improve delivery of therapeutic agents.

We currently have two FDA-cleared devices. To learn more about our platform combining pressure-enabled delivery with immunomodulatory therapeutics, visit our platform page.

Transhepatic Drug Delivery to Liver Tumors

Our technology has been shown to overcome intratumoral pressure (ITP) and enable targeted drug delivery of therapeutics to primary liver tumors and liver metastases via the peripheral vascular system.  The technology enables therapeutic delivery to all tumors in the liver in addition to micro-metastases and dysfunctional immune cells throughout the organ. 

TriNav® Infusion System

The FDA-cleared TriNav infusion system with SmartValve® technology enables delivery of therapeutic agents to selected sites in the peripheral vascular system, including tumors in the liver and the entire organ in the presence of micro-metastases.

Retrograde Venous Delivery to Pancreatic Tumors

Retrograde venous delivery to the pancreas involves the placement of a PEDD device into the veins draining the pancreas to enable targeted delivery of therapeutics. Unlike the liver, small vessels and extensive collateralization in the pancreas make the arterial route challenging for targeted delivery. Retrograde venous infusion provides a potentially more feasible and reliable strategy for targeted delivery of therapeutics through direct venous access.

Pancreatic Retrograde Venous Infusion (PRVI™) System

The PRVI System with SmartValve technology is an FDA-cleared device for delivery of therapeutics to the peripheral vasculature.  This device is being studied for the delivery of SD-101 via the PRVI approach into unresectable pancreatic tumors.

The PRVI System is positioned in the vasculature using standard interventional radiology procedures. The PRVI System isolates the tumor bed and enables pressure measurement during infusion for uniformity of procedural approach.

TriSalus' Platform Approach

At TriSalus, we believe that a therapeutic approach that simultaneously reduces immunosuppressive populations and improves therapeutic delivery to tumor tissue holds great promise for patients with few good options.
