INTRAVASKUläRER KATHETER |
摘要 |
The present invention provides improvement usable with an intravascular catheter having a single common distal lumen with a reduced profile connected to two or more proximal lumens. The catheter will be loadable over a guidewire into a region of interest within a patient's vascular system. According to one aspect of the present invention, means are provided to ensure that the guidewire enters into a desired one of the proximal lumens. In a preferred embodiment, a special tool is provided to achieve this. According to a second aspect of the present invention, the catheter is provided with a proximal housing and an axially expandable member to shield the rotating parts at the proximal end of the catheter and to allow for convenient movement of a work element within the catheter body. |
