Vascular introducer sheath with retainer
First Claim
1. A surgical vascular introducer sheath comprising:
- a first member having a first outer wall, a first side opening in the outer wall, and a first longitudinally extending lumen, the first lumen configured and dimensioned to receive a surgical instrument therethrough and the first side opening being in fluid communication with the first lumen;
a second member having a second outer wall, a second longitudinally extending lumen, and a second side opening in the outer wall in fluid communication with the second lumen, at least a portion of the first member being positioned within the second lumen of the second member; and
a retainer positioned at a distal portion of the first member, the retainer movable from a first retracted position to a second extended position to limit proximal movement of the introducer sheath, the retainer movable in response to movement of the first member, wherein movement of the first member in a first direction moves the retainer to the extended position and movement of the first member in a second direction moves the retainer to a retracted position, and movement of the first member in the first direction to extend the retainer moves the first and second side openings from a non-aligned position to an aligned position.

Abstract
The present invention provides a surgical vascular introducer sheath comprising first and second members and a retainer. The first member has a first longitudinally extending lumen configured and dimensioned to receive a surgical instrument therethrough and a first side opening in an outer wall in fluid communication with the first lumen. The second member has a second longitudinally extending lumen and a second side opening in fluid communication with the second lumen, wherein at least a portion of the first member is positioned within the second lumen of the second member. The retainer is positioned at a distal portion of the first member and is movable from a first retracted position to a second extended position to limit proximal movement of the introducer in response to movement of the first member. Rotational movement of the first member in a first direction moves the retainer to the extended position and rotational movement of the first member in a second direction moves the retainer to a retracted position and moves the first and second side openings from a non-aligned position to an aligned position.

12. A surgical sheath for providing a passageway for instrumentation into a vessel comprising:
-
a first tubular member having a first lumen extending longitudinally therein configured and dimensioned for receiving surgical vascular instruments therethrough;
a second tubular member having a second lumen extending longitudinally therein, at least a portion of the first tubular member positioned within the second lumen of the second tubular member; and
a retainer extendable from the first tubular member and spaced proximally from a distalmost tip of the first tubular member, the retainer limiting proximal movement of the sheath with respect to the vessel to prevent dislodgement of the sheath from the vessel incision, the retainer being movable from a first retracted position to a second extended position extending laterally with respect to the tubular member in response to rotational movement of the first tubular member.

18. A method for preventing dislodgement of a vascular introducer sheath through a vascular incision when the introducer sheath is positioned through the incision with a distal portion extending into the vessel, the method comprising the steps of:
-
inserting an introducer sheath through an incision in the vessel wall so a distal portion of the sheath extends into the vessel, rotating an inner tubular member of the introducer sheath to move a retainer from a retracted position to an extended position so the retainer extends radially outwardly with respect to the introducer sheath, introducing a surgical vascular instrument into the introducer sheath;
performing a surgical step in a vascular procedure with the surgical instrument;
withdrawing the surgical instrument, the retainer preventing proximal movement of the introducer sheath through the vessel incision during withdrawal of the surgical instrument; and
rotating the inner tubular member of the introducer sheath to return the retainer to its retracted position; and
removing the introducer sheath from the vessel through the vascular incision.
