Abstract

Multilayer balloon for a catheter comprises a first layer made of a first polymer material having a first Shore durometer hardness, a second layer made of a second polymer material having a second Shore durometer hardness greater than the first Shore durometer hardness, wherein the second layer is an inner layer relative to the first layer, and a third layer made of a third polymer material having a third Shore durometer hardness less the first Shore durometer hardness, wherein the third layer is an inner layer relative to the second layer. Method of making a multilayer balloon for a catheter and a balloon catheter are also provided.

Description

[0001] This application claims priority to US application number 13 / 680,299 filed on November 19, 2012, entitled "Multi-Layered Balloon For A Catheter", the disclosure of which is adopted as a whole The reference is incorporated into this article. Technical field [0002] The disclosed subject matter relates to the field of intravascular medical devices. More specifically, the subject matter of the present disclosure relates to a multilayer balloon for catheters. Background technique [0003] Balloon catheters are used in various treatments and techniques for intraluminal indications (including cardiovascular and peripheral systems) throughout the body. One such method is called percutaneous transluminal coronary angioplasty (PTCA) surgery. For illustrative purposes, in a PTCA procedure, the guide catheter is advanced until the distal tip of the guide catheter is in the orifice of the desired coronary artery. The guide wire is then advanced to exit from the distal end of the gu...
