TRAP BALLOON CATHETER WITH TRAP BALLOON RETAINER

摘要

Medical devices, medical device systems, and methods for using the same are disclosed. An example medical device system may include a guide catheter having a proximal end, a distal end, and a lumen extending therebetween. The guide catheter may be designed to guide a therapeutic catheter to a target site. A guidewire may be disposed within the lumen of the guide catheter. The system may also include a trap balloon catheter including a catheter shaft and a balloon coupled to the catheter shaft. The trap balloon catheter may be designed to extend through the lumen of the guide catheter to a position adjacent to the distal end of the guide catheter. A trap balloon retainer may be coupled to the catheter shaft. The trap balloon retainer may be designed to prevent a distal end of the trap balloon catheter from extending distally beyond the distal end of the guide catheter.

1. A medical device system, comprising:
a guide catheter having a proximal end, a distal end, and a lumen extending therebetween; wherein the guide catheter is designed to guide a therapeutic catheter to a target site; a guidewire disposed within the lumen of the guide catheter; a trap balloon catheter including a catheter shaft and a balloon coupled to the catheter shaft; wherein the trap balloon catheter is designed to extend through the lumen of the guide catheter to a position adjacent to the distal end of the guide catheter; wherein the balloon is designed to be expanded in order to secure the position of the guidewire relative to the guide catheter by securing the guidewire between the balloon and an inner surface of the guide catheter; and a trap balloon retainer coupled to the catheter shaft, the trap balloon retainer being designed to prevent a distal end of the trap balloon catheter from extending distally beyond the distal end of the guide catheter.
