ABSTRACT:
An over-the-wire rapid-exchange catheter having a distal guidewire channel and a proximal guidewire channel. The catheter is exchanged by withdrawing the catheter from a guiding catheter until the guidewire can be removed from the proximal guidewire channel and then further withdrawn in the conventional fashion. The proximal guidewire channel provides a sealing surface for a releasable seal on the guiding catheter, avoiding the gripping of the guidewire.
