Abstract
An introducer sheath includes a tubular body portion having a proximal region and a distal region, and defines an internal lumen configured and dimensioned to slidably receive a catheter. A penetrating portion at a distal end of the tubular body has a first tapered configuration to enlarge an opening in a body tissue during distal advancement of the introducer sheath through the body tissue and a second expanded configuration to enable the passage of a distal end portion of a catheter through the penetrating portion.
Claims7
An introducer sheath comprising:
- a tubular body portion having a proximal region and a distal region and defining an internal lumen configured and dimensioned to slidably receive a catheter;
- and
- a penetrating portion at a distal end of the tubular body portion having a first tapered configuration to enlarge an opening in a body tissue during distal advancement of the introducer sheath through the body tissue and a second expanded configuration to enable the passage of a distal end portion of a catheter through the penetrating portion, the penetrating portion being separable from the tubular body portion via perforations and configured to be maintained on the catheter to act as a barrier between body tissue and the catheter and to increase a kink resistance of the catheter adjacent a proximal end portion of the catheter.
