Abstract
Abstract A rapid exchange stent delivery catheter which includes an inner tubular member and an outer tubular member slidably disposed thereon. The inner tubular member and the outer tubular member have rapid exchange type guide wire openings. The guide wire opening of the outer tubular member is preferably shorter in length than the guide wire opening of the inner tubular member to protect the inner workings of the catheter. The outer tubular member may include a guide wire access sleeve having a guide wire ramp extending into the guide wire lumen of the inner tubular member. The guide wire sleeve may be a separate component from the remainder of the outer tubular member to facilitate efficient manufacture.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
178 words
A rapid exchange stent delivery catheter for delivering a self-expandable stent over a guide wire to a bodily lumen, the catheter comprising: an inner tubular member having a proximal end, a distal end, a stent holding portion located adjacent the distal end of the inner member, and a guide wire lumen extending from a proximal guide wire opening disposed distal of the proximal end of the inner member to a distal guide wire opening disposed at the distal end of the inner member, wherein the proximal guide wire opening has a length; an outer tubular member slidably disposed about the inner member, the outer member having a proximal end, a main portion, a distal end, and a guide wire opening disposed distal of the proximal end of the outer member, wherein the guide wire opening of the outer member has a length that is shorter than the length of the proximal guide wire opening of the inner member, wherein the outer member is sized to cover a major portion of the proximal guidewire opening of the inner member.
Claim 2
Dependent Claim
178 words
A rapid exchange stent delivery catheter for delivering a self-expandable stent over a guide wire to a bodily lumen, the catheter comprising: an inner tubular member having a proximal end, a distal end, a stent holding portion located adjacent the distal end of the inner member, and a guide wire lumen extending from a proximal guide wire opening disposed distal of the proximal end of the inner member to a distal guide wire opening disposed at the distal end of the inner member, wherein the proximal guide wire opening has a length; an outer tubular member slidably disposed about the inner member, the outer member having a proximal end, a main portion, a distal end, and a guide wire opening disposed distal of the proximal end of the outer member, wherein the guide wire opening of the outer member has a length that is shorter than the length of the proximal guide wire opening of the inner member, wherein the outer member is sized to cover a major portion of the proximal guidewire opening of the inner member.
Claim 3
Dependent Claim
199 words
A rapid exchange stent delivery catheter for delivering a self-expandable stent over a guide wire to a bodily lumen, the catheter comprising: an inner tubular member having a proximal end, a distal end, a stent holding portion located adjacent the distal end of the inner member, and a guide wire lumen extending from a proximal guide wire opening disposed distal of the proximal end of the inner member to a distal guide wire opening disposed at the distal end of the inner member, wherein the proximal guide wire opening has a length; an outer tubular member slidably disposed about the inner member, the outer member having a proximal end, a main portion, a distal end, and a guide wire opening disposed distal of the proximal end of the outer member, wherein the guide wire opening of the outer member has a length that is shorter than the length of the proximal guide wire opening of the inner member; and wherein the outer tubular member includes a guide wire access sleeve in which the guide wire opening is disposed, the guide wire access sleeve having a guide wire ramp extending into the guide wire lumen of the inner tubular member.
