Catheter incorporating a high column strength distal tip region |
摘要 |
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tip to allow the tip to return to the initial 0.12 -inch accommodating profile when the larger 0.14-inch guidewire is withdrawn from the catheter. |
