Abstract
A catheter with an elastic reinforcement layer allows its catheter tube to expand from a native diameter to an expanded diameter. In this respect, a device or implant with a larger diameter than that of the catheter tube's native diameter size can be passed through the catheter without damage.
Claims20
A catheter comprising:
- a catheter hub;
- and,
- a catheter tube having a proximal end connected to said catheter hub;
- said catheter tube elastically expanding from a predetermined, native diameter to accommodate passage of an implant having an implant diameter larger than said predetermined, native diameter.
