Title:
BALLOON CATHETER STENT DELIVERY SYSTEM WITH RIDGES
Document Type and Number:
WIPO Patent Application WO2002066096
Kind Code:
B1
Abstract:
A balloon catheter and stent delivery system (10) for medical treatment of a patient includes a balloon (12) having a pattern of ridges (50) in an initial deflated state. The ridges (50) may cooperate with structural elements of a stent (34) crimped onto the balloon (12) to increase and enhance longitudinal retention of the stent (50) while the catheter system (10) is advanced or withdrawn. Upon inflation, the balloon (12) recovers to an inflated shape having a cylindrical working portion (36). The balloon catheter (10) thus provides for uniform expansion of the stent (34) when the balloon (12) is inflated. The present invention also tends to protect the leading or distal end of the stent (50) during advancement, and tends to protect the proximal end of the stent (50) during any withdrawal of the catheter system (10).
