Flexible collar support.

摘要

The flexible collar support (10) of this invention extends over the tube (12) of a catheter or an introducer sheath to provide resilient collar which supports the tube and prevents it from kinking adjacent to the hub. The flexible collar support (10) comprises a substancially cylindrical body made of a resilient material and having a central bore whose dimensions are substantially the same as the external dimensions of the tube (12), the body being comprised of a first set of disks (14) having substantially wide diameters which are separated from one another by a second set of disks (16) having a substantially narrower diameter.
