发明名称 Angioplasty dilitation balloon catheter
摘要 A dilitation balloon catheter with an inelastic balloon disposed in a streamlined configuration having a smaller deflated cross-sectional profile than any catheter hereto available and yet a potentially larger inflation caliber than prior art "low profile" catheters. During introduction across a region of stenosis, the balloon is wrapped around a guidewire in such a way that the guidewire contained therein can move freely. The wrapped configuration is maintained by means of a temporary bond. Inflation of the balloon, following proper positioning of the catheter results in disruption of the aforementioned bond, permitting a balloon to unwrap from the guidewire contained therein.
