Patent ID: 7367967

Claim:
A catheter assembly comprising: a substantially hollow proximal tubular member, at least a portion of the proximal tubular member having a coating of at least one thermoplastic polymer thereabout, the proximal tubular member having an end region, at least the end region having the coating of at least one thermoplastic polymer; a substantially distal outer tubular member, the distal outer tubular member having an end region, a first portion of the end region of the distal outer tubular member being engaged to a first portion of the coating on a first portion of the end region of the proximal tubular member to define a first engagement region, the first engagement region comprising the first portion of the end region of the distal outer tubular member radially overlapping the first portion of the end region of the proximal tubular member, a first portion of the coating and the first portion of the end region of the distal outer tubular member being bonded together, the proximal tubular member and the distal outer tubular member defining at least one continuous central lumen therethrough; and a substantially hollow inner tubular member, at least a portion of the distal outer tubular member disposed about at least a portion of the inner tubular member, a first portion of the inner tubular member engaged to the coating on a second portion of the end region of the proximal tubular member to define a second engagement region, a second portion of the inner tubular member engaged to a second portion of the end region of the distal outer member to define a third engagement region, the end region of the proximal tubular member extending distally into the distal outer tubular member adjacent to the at least a portion of the inner tubular member.
