長さ方向において高い強度を有する先端チップ領域を組み込んだカテーテル
Document Type and Number:
Japanese Patent JP2005519648
Kind Code:
A
Abstract:
A catheter is disclosed providing a balloon catheter having a distal tip that is flexible while additionally incorporating high column strength. The present invention additionally provides a distal tip region that accommodates for various sized guidewires. In preferred embodiments, the distal tip region is initially configured for accommodating the passage of 0.12-inch guidewires only. Through specific manufacturing processes, however, the distal tip is modified so that it also may be expanded to accommodate the passage of 0.14-inch guidewires. In additional preferred embodiments, an elastomeric sleeve is disposed over the modified distal tip to allow the tip to return to the initial 0.12 -inch accommodating profile when the larger 0.14-inch guidewire is withdrawn from the catheter.
