Abstract
A catheter sheath introducer comprising a tubular sheath having a proximal end and a distal end are provided. A hub is coupled to the proximal end of the tubular sheath and a coil spring is also provided. The coil spring is positioned about the proximal end of the tubular sheath, and the sheath and coil spring are coupled to the hub in such a way that the tubular sheath and coil spring extend within the hub and out from the hub whereby the strain produced when the tubular sheath and hub are moved relative to one another is relieved.
Claims19
A catheter sheath introducer comprising:
- a hub;
- a hemostasis valve within said hub;
- a tubular sheath having a proximal end and a distal end;
- said proximal end of said tubular sheath being molded to said hub;
- a coil spring having a smaller length than the length of said tubular sheath;
- said coil spring tightly and unattachedly overlying said proximal end of said tubular sheath;
- said coil spring being molded to said hub such that said proximal end of said tubular sheath and coil spring extend within said hub and extend out from said distal end of said hub whereby the strain produced when said tubular sheath and hub are moved relative to one another is relieved.
