Sliding connection assembly to facilitate lead stabilization
First Claim
1. A connection system for connecting a hemostatis valve to a sheath, the system comprising:
- a hemostasis valve having a cannula portion disposed on a distal end and a first ledge protruding from an outer surface of the cannula portion and disposed proximally from the distal end of the cannula portion;
a sheath having a nipple extending proximally therefrom, wherein the nipple further comprises;
a second ledge disposed on an outer surface of the nipple;
a nipple lumen adapted for receiving the distal end of the cannula portion of the hemostasis valve; and
a sliding connector in the form of an annular wall defining a connector lumen and disposed about the outer surface of the cannula portion of the hemostasis valve and the outer surface of the nipple of the sheath when the cannula portion is received in the lumen of the nipple;
wherein at least one of the cannula portion and the nipple are received in the connector lumen;
the sliding connector slides proximally and distally along an interface between the cannula portion of the hemostasis valve and the nipple of the sheath when the cannula portion is received in the lumen of the nipple; and
the sliding connector further comprises an engagement means for engaging at least one of the first ledge and the second ledge to connect the hemostasis valve and the sheath.

Abstract
A connection system for connecting a hemostasis valve to a sheath is disclosed. The hemostasis valve has a cannula portion disposed on a distal end and an annular ledge protruding from an outer surface thereof. The sheath has a nipple extending proximally therefrom. The nipple also has an annular ledge disposed on an outer surface thereof and a nipple lumen adapted for receiving the distal end of the cannula portion. A sliding connector defining a connector lumen is disposed about the outer surface of the cannula portion and the outer surface of the nipple when the cannula portion is received in the lumen of the nipple. A connection between the hemostasis valve and the sheath is created by engaging the sliding connector with either or both of the annular ledge on the hemostasis valve and the annular ledge on the nipple.
