Abstract:
An assembled catheter assembly comprising:an elongate member having a distal end, a proximal end, a lumen between said proximal end and said distal end, a distal region adjacent said distal end, a proximal region located proximally from said distal region, a polymeric outer filler layer extending along at least a portion of said elongate member, and an axis between said distal end and said proximal end,wherein said distal region comprises:a.) an inner lubricious layer forming a portion of said lumen,b.) a kink-resisting member exterior to said inner lubricious layer having a distal end and a proximal end wherein said proximal region does not contain said kink-resisting member, said polymeric outer layer being exterior to said kink-resisting member,c.) a junction region being exterior to said inner lubricious layer and proximal of said kink-resisting member, said junction region being axially adjacent to said proximal end of said kink-resisting member,and wherein said junction region comprises and is assembled from at least two interfitting conical members during at least one assembly step, one conical member having a male conical surface and one conical member having a female conical surface, said one conical member having a male conical surface being slideable with respect to said one conical member having a female conical surface during said at least one assembly step.
