Abstract:
1. An endovascular access sheath system adapted for introducing and removing an intra-aortic balloon pump catheter, comprising: an axially elongate sheath tube with a proximal end, a distal end, and a central through lumen opening at said proximal end and said distal end; said sheath tube further comprising an expandable region having a first, collapsed configuration with a first through lumen diameter and a second, expanded configuration with a second through lumen diameter; a hub affixed to the proximal end of the sheath tube, the hub adapted to facilitate the passage of instrumentation and substantially seal against the loss of blood; an intra-aortic balloon counterpulsation catheter slidably disposed within the endovascular access sheath, the catheter comprising an expandable pumping balloon; a sheath dilator disposed within the sheath tube and expands the expandable region from the first, collapsed configuration to the second, expanded configuration; and a guidewire lumen within an obturator, capable of passing over standard medical guidewires and which will allow the obturator and sheath to track over said guidewires into an arterial access site.
