Catheter for delivery and/or retrieval of a medical device

摘要

A catheter for delivery or retrieval of a medical device such as a filter 10 or a stent 16 has an outer shaft 1 with a pod 2 providing a medical device reception space at the distal end. An inner shaft 3 includes a solid pod with a longitudinally extending surface pathway 4 for a guidewire 7. The inner shaft 3 defines an abutment surface 9 at its distal end for deployment of the device 10, 16. The outer shaft 1 has an exit port 8 at which the guidewire 7 exits the catheter in a rapid exchange manner.
