What changed

This document is a USPTO patent application (US20260083942A1) filed on December 1, 2025, for a novel non-occluding balloon catheter device intended for cardiovascular drug delivery. The device features a bypass lumen that ensures continued blood flow when the balloon is inflated, while simultaneously pressing a drug coating against the blood vessel wall. The abstract highlights the dual functionality of maintaining blood transport and delivering therapeutic agents.

This patent application represents a new technological development in the medical device and pharmaceutical sectors. While it does not impose immediate compliance obligations, it signals potential future innovations in drug-eluting balloon technology. Companies involved in cardiovascular devices, drug coatings, and interventional cardiology should monitor patent filings in this area for competitive intelligence and potential licensing opportunities. No specific compliance deadlines or penalties are associated with a patent application itself.

NON-OCCLUDING BALLOON FOR CARDIOVASCULAR DRUG DELIVERY

Abstract

A non-occluding drug-coated balloon catheter device for use in a blood vessel transporting blood comprises a catheter shaft including a guidewire lumen, a fluid lumen and a connector port. A balloon is mounted on the catheter shaft and includes an outer envelope surrounding the guidewire lumen in fluid communication with the fluid lumen; a drug coating applied on the exterior surface of the outer envelope; and at least one bypass lumen forming a passage extending from the proximal end of the outer envelope to the distal end of the outer envelope. When the balloon is positioned in a blood vessel and inflated, the exterior surface of the outer envelope presses the drug coating against the blood vessel and the bypass lumen is open between the distal end of the outer envelope and the proximal end of the outer envelope such that blood transport continues through the bypass lumen.
