Claim:
A rapid exchange catheter having a proximal end and a distal end, the catheter comprising: an outer member having a proximal end and a distal end; and an inner member having a proximal end and a distal end; wherein: a guidewire port opens into the outer member and into the proximal end of the inner member at a location along the outer member distal of the proximal end of the outer member; the inner member extends distally inside the outer member from the guidewire port beyond the distal end of the outer member; the inner member is sized and adapted to receive a guidewire therethrough, the inner member having a first diameter along a majority of its length sufficient to allow fluid passage therethrough while the guidewire is disposed therethrough, wherein the inner member includes a first material; and a seal is disposed within the inner member at a location spaced from the distal end of the inner member, wherein the seal is located nearer the proximal end of the inner member than the distal end of the inner member, wherein the seal includes the first material.
