US 2026/0158247 A1 · BALLOON CATHETER

Abstract

The present invention relates to a balloon catheter. The balloon catheter includes a tubular member and an expandable member. The tubular member defines an inflation lumen therein at least to facilitate a fluid flow. The expandable member is mounted to a distal end section of the tubular member and defines a chamber therein. The chamber fluidically communicates with the inflation lumen and enables the expandable member to transition between an inflated configuration and a deflated configuration. The expandable member is configured with a proximal diametrical size and a distal diametrical size. The distal diametrical size is larger than the proximal diametrical size. The expandable member increases from the proximal diametrical size to the distal diametrical size, along a longitudinal axis thereof, and is adapted to dilate the body lumen in the inflated configuration.

Dependent claims

A balloon catheter, comprising:

a tubular member defining an inflation lumen therein at least to facilitate a fluid flow, the tubular member comprising:
a proximal end section adapted to be fluidically coupled to a fluid source;
and
a distal end section adapted to be introduced into a body lumen at least through retrograde access thereof;
and
an expandable member mounted to the distal end section and defining a chamber therein, wherein the chamber fluidically communicates with the inflation lumen and enables the expandable member to transition between an inflated configuration and a deflated configuration,
wherein the expandable member is configured with a proximal diametrical size and a distal diametrical size larger than the proximal diametrical size, the expandable member increasing from the proximal diametrical size to the distal diametrical size along a longitudinal axis thereof and adapted to dilate the body lumen in the inflated configuration.
