First Claim
Patent Images
1. A guide catheter for use in cardiovascular diagnostic or surgical procedures comprising:
- (a) an elongated, flexible, non-bifurcated tube having a distal end and a proximal end, said tube having an internal lumen of a diameter sufficiently large to receive a working catheter and a guidewire therein in a loose-fitting, side-by-side disposition, said guidewire and said working catheter being of a greater length than said tube such that portions of said guidewire and said working catheter can be made to extend beyond both said distal end and said proximal end of said guide catheter; and
(b) hub means having a single entry/exit port and affixed to said proximal end of said guide catheter for maintaining the portions of said guidewire and said working catheter extending through said entry/exit port of said hub means spaced apart from one another for ease of gripping and with said guidewire being selectively clamped against movement relative to said guide catheter.
