Balloon catheter with longitudinal safety stop
First Claim
Patent Images
1. A balloon catheter for therapeutically treating a patient, comprising:
- a flexible catheter shaft having proximal and distal ends, and defining at least one lumen;
a hub affixed to the shaft proximal end;
a balloon affixed to the shaft near the distal end, the balloon communicating with the lumen for selective inflation and deflation, wherein the balloon is made of a substantially inelastic material; and
a safety stop affixed to the balloon and having a component extending in a longitudinal direction;
the balloon and safety stop being made of different materials having different physical properties, wherein the resulting balloon and safety stop assembly has the physical property tending to redirect a possible failure of the balloon material to follow a more longitudinal path;
wherein the safety stop is formed as a polymer insert in the wall surface of the balloon.

Abstract
The present invention relates to a balloon catheter having a tubular basic body with distal and proximal ends, and at least one lumen extending between the proximal and the distal ends. A balloon is attached to the basic body close to the distal end which is connected with the lumen, so that the balloon may be selectively expanded by means of supplying a medium under pressure through the lumen. The balloon has at least one safety stop, which may extend between the distal and the proximal end of the balloon.

8. A balloon for a balloon catheter to provide medical treatment to a patient, comprising:
-
a tubular substantially inelastic balloon having a central cylindrical working portion having proximal and distal ends, each end connected to a proximal and distal tapering portion respectively, and a pair of proximal and distal balloon legs connected to the tapering portions; and
a safety stop affixed to the balloon and extending along at least the working portion of the balloon;
the balloon and safety stop being made of different materials having different physical properties, wherein the resulting balloon and safety stop assembly has the physical property tending to redirect a possible failure of the balloon material to follow a more longitudinal path;
wherein the safety stop is formed as a polymer insert in the wall surface of the balloon.
