Stent delivery system with spacer member
First Claim
1. A stent delivery system for delivering a stent to a deployment site in a body lumen of a patient'"'"'s body, said stent delivery system comprising:
- an elongated, flexible, hollow outer tubular member having a distal end and a proximal end;
an elongated, flexible, inner tubular member having a distal end and a proximal end;
said outer tubular member sized to be passed through said body lumen with said distal end advanced to said deployment site and with said proximal end external to said body for manipulation by an operator;
said inner tubular member sized to be received within said outer tubular member with said inner tubular member and said outer tubular member axially slideable relative to one another between a transport position and a deploy position;
said inner tubular member having a stent attachment location at said distal end of said inner tubular member, said stent attachment location covered by said outer tubular member when said inner and outer tubular members are in said transport position, said stent attachment location exposed when said inner and outer tubular members are in said deploy position;
a spacer member disposed between said inner tubular member and said outer tubular member with said spacer member spacing said inner tubular member from said outer tubular member;
opposing surfaces of said inner and outer tubular members defining a first lumen extending from said proximal end towards said distal end of said outer tubular member;
an admission port in communication with said first lumen at proximal end of said outer tubular member; and
a discharge port through said outer tubular member in communication with first said lumen at said distal end of said outer tubular member.

Abstract
A stent delivery system includes outer and inner elongated, flexible tubular members each having a distal and proximal ends. The outer tubular member is sized to be passed through the body lumen with the distal end advanced to the deployment site and with the proximal end remaining external of the patient'"'"'s body for manipulation by an operator. The inner tubular member is sized to be received within the outer tubular member. The outer tubular and inner tubular members are axially slideable relative to one another between a transport position and the deploy position. The inner tubular member has a stent attachment location at its distal end. The stent attachment location is covered by the outer tubular member when the inner and outer tubular members are in the transport position. The stent attachment location is exposed when the inner and outer tubular members are in the deploy position. A spacer member is disposed between the inner and outer tubular members. The spacer member maintains spacing between the inner and outer tubular members. Opposing surfaces of the inner and outer tubular members define a first lumen extending from the proximal end towards the distal end of the outer tubular member. An admission port is provided in communication with the first lumen at the proximal end of the outer tubular member. A discharge port is formed through the outer tubular member in communication with the first lumen at the distal end of the outer tubular member.
