Abstract
A dual functioning instrument set, comprising a needle and guide, has not only the capabilities to enter and insufflate the abdominal cavity but also the ability of a suture passer to carry and retrieve suture for closure of the incision sites at the end of the procedure. The needle contains a deployable snare that is used to pass and retrieve suture. The guide is used to repeatedly locate the needle relative to the inner abdominal wall allowing for consistent placement of sutures. For insufflation purposes, obturator tips having different distal structures are provided for shielding the sharp needle tip after insertion through a body wall.
Claims20
A suture passer guide comprising:
- a barrel having a longitudinal axis;
- and
- an expandable member secured to a distal end region of the barrel, the expandable member configured to be positioned in an expanded position in which the expandable member extends radially beyond the barrel, the expandable member comprising a first collapsible arm and a second collapsible arm that are spaced around a circumference of the expandable member, the expandable member defining a first gap that extends between the first and second collapsible arms around the circumference of the expandable member, and the first gap being open and uncovered,
- wherein the barrel defines a first proximal opening and a first distal opening that are substantially aligned with one another such that a suture passer can be extended through the first proximal and distal openings at an acute angle relative to the longitudinal axis of the barrel, and the first gap defined by the expandable member is longitudinally aligned with the first distal opening such that the suture passer, when extended through the first proximal and distal openings with the expandable member in the expanded position, passes through the first gap extending between the first and second collapsible arms, is spaced from the expandable member along the length of the expandable member.

A suture passer guide comprising:
- a barrel having a longitudinal axis;
- an expandable member secured to a distal end region of the barrel, the expandable member configured to be positioned in an expanded position in which the expandable member extends radially beyond the barrel;
- a first collapsible arm and a second collapsible arm spaced around a circumference of the expandable member;
- and
- a first gap extending between the first and second collapsible arms around the circumference of the expandable member,
- wherein the barrel defines a first proximal opening and a first distal opening that are substantially aligned with one another such that a suture passer can be extended through the first proximal and distal openings at an acute angle relative to the longitudinal axis of the barrel, and the first gap defined by the expandable member is longitudinally aligned with the first distal opening such that the suture passer, when extended through the first proximal and distal openings with the expandable member in the expanded position, passes through the first gap extending between the first and second collapsible arms, is spaced from the expandable member along the length of the expandable member, is free from contact with any portion of the expandable member or any structure defined by the expandable member, and can position an unsecured end region of a suture radially adjacent the first gap.

A suture passer guide comprising:
- a barrel having a longitudinal axis;
- a first proximal opening in the barrel;
- a first distal opening in the barrel substantially aligned with the first proximal opening such that a suture passer can be extended through the first proximal and distal openings at a first acute angle relative to the longitudinal axis of the barrel;
- a second proximal opening in the barrel;
- a second distal opening in the barrel substantially aligned with the second proximal opening such that a suture passer can be extended through the second proximal and distal openings at a second acute angle relative to the longitudinal axis of the barrel;
- a shaft disposed within a lumen of the barrel, the shaft defining a first path, joining the first distal opening with the first proximal opening, and a second path, joining the second distal opening with the second proximal opening;
- an expandable member secured to a distal end region of the barrel, the expandable member configured to be positioned in an expanded position in which the expandable member extends radially beyond the barrel, the expandable member comprising a first collapsible arm and a second collapsible arm that are spaced around a circumference of the expandable member;
- and
- wherein the first and second collapsible arms are circumferentially offset to the first distal opening and the second distal opening in the barrel.
