Neuravi Catheter Navigation Device Minimizes Vessel Bifurcation Catching
Summary
USPTO published patent application US20260097189A1 for Neuravi Limited, filed October 9, 2024, covering an endovascular navigation device for use with funnel catheters. The device features a radially expandable section positioned between a tapered distal section and proximal section, designed to prevent the free terminating distal edge of a funnel catheter from catching at bifurcated vessels during navigation. The expandable section expands to match the catheter's maximum inner diameter when deployed. The invention addresses complications in catheter procedures at vessel bifurcations.

USPTO published patent application US20260097189A1 for Neuravi Limited, covering a catheter navigation device designed to prevent catching at vessel bifurcations. The device comprises a radially expandable section positioned between a tapered distal section and proximal section, advanceable within a funnel catheter lumen. When expanded, the radially expandable section matches the catheter's maximum inner diameter, preventing the free terminating distal edge from catching during navigation through bifurcated vessels. The system then collapses and withdraws from the catheter.
For medical device manufacturers and developers of endovascular catheter systems, this patent application indicates Neuravi's technological approach to addressing bifurcation complications in catheter procedures. Companies developing similar catheter navigation or funnel catheter systems should review the claims for potential overlap with their own IP portfolios or product development strategies.

NAVIGATION DEVICE FOR USE WITH A FUNNEL CATHETER MINIMIZING CATCHING AT A VESSEL BIFURCATION

Abstract
Endovascular medical system and method for preventing catching of a free terminating distal edge of a funnel catheter at a bifurcated vessel using a navigation device advanceable in a lumen of the funnel catheter and having a radially expandable section interposed between a tapered distal section and a proximal section. The radially expandable section of the navigation device in a radially expanded state has a maximum outer diameter substantially equal to the maximum inner diameter at the free terminating distal edge of the radially expandable distal section of the funnel catheter while in the radially expanded state. While traversing the bifurcated vessel, the radially expandable section of the navigation device in the radially expanded state prevents catching of the free terminating distal edge of the funnel catheter. Thereafter, the navigation device is collapsed and withdrawn from the funnel catheter.
