摘要：
1. The catheter assembly, comprising a catheter having a proximal and distal ends； an expandable device removably attached to the catheter near the distal end； a restrictive cuff extending around the device and compressing it to an outer circumferential size suitable for endoluminal delivery and having an end facing the distal end of the catheter； a tip fixedly connected to the distal end of the catheter； and an overlapping element located between the tip and the expandable device and filling the gap between them. 2. The catheter assembly of claim 1, wherein the closure member is substantially annular and comprises a tapered surface radially connected to an expandable device and / or a restrictive collar. The catheter assembly of claim 2, wherein the tapered surface exerts radially outwardly directed pressure on the expandable device and / or on the restrictive cuff. The catheter assembly of claim 3, wherein the beveled surface generally has the shape of a truncated cone. The catheter assembly according to claim 1, wherein the catheter comprises a cavity extending between the proximal and distal ends, and which further includes a tubular element extending through said cavity, the end of which is fixedly connected to the tip. The catheter assembly of claim 5, wherein the tubular member comprises a conduit cavity extending axially through it. The catheter assembly of claim 6, wherein the closure member is substantially annular and comprises a channel receiving the tubular member. The catheter assembly of claim 1, wherein the overlapping element fills the gap between the tip and1.
