Publication number: 20100298859Abstract: 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tip to allow the tip to return to the initial 0.12-inch accommodating profile when the larger 0.14-inch guidewire is withdrawn from the catheter.Type: ApplicationFiled: August 2, 2010Publication date: November 25, 2010Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Paul J. Miller, Tracee E.J. Eidenschink
