Abstract
A tissue closure device to assist in retrieving a suture during a suturing procedure, the device including an elongated body having a proximal end, a distal end, and a lumen extending axially through the elongated body. The device further including an actuator rod at least partially extending through the lumen of the elongated body to actuate a plurality of wings and a plurality of shields attached to a distal end of the elongated body. The elongated body including at least one needle guide lumen with an opening an exit, the at least one needle guide lumen traversing the elongated body at an angle with respect to a central axis of the elongated body to guide a suture grasper to an enclosed suture retrieval cavity.
Claims14
A tissue closure device, comprising:
- an elongated body defining a central longitudinal axis and including a proximal end, a distal end, and a lumen extending axially through the elongated body;
- and
- an actuator rod at least partially extending through the lumen of the elongated body,
- wherein the elongated body includes at least one needle guide lumen with an opening and an exit, the at least one needle guide lumen traversing the elongated body at an angle with respect to a central longitudinal axis of the elongated body,
- wherein a distal portion of the elongated body is pivotally connected to a plurality of wings, which are pivotally connected to a plurality of shields,
- wherein the plurality of shields are pivotally connected to a distal tip portion of the device, the distal tip portion being attached to a distal end of the actuator rod,
- wherein the plurality of wings each include an opening to allow passage into a suture retrieval space defined between one each of the plurality of wings and plurality of shields when said wings and shields are extended away from the elongated body in a deployed position of the device, and
- wherein the plurality of shields is configured to prevent inadvertent needle perforation of organs, vessels, or other tissues from an object inserted through at least one of the openings of the plurality of wings.
A tissue closure system for a suturing procedure, comprising:
- a suture grasper;
- and
- a tissue closure template, the template including an elongated body defining a central longitudinal axis and having a proximal end, a distal end, a lumen extending axially through the elongated body, an actuator rod at least partially extending through the lumen of the elongated body, and at least one needle guide lumen traversing the elongated body at an angle with respect to a central axis of the elongated body,
- wherein a distal portion of the elongated body is pivotally connected to a plurality of wings, which are pivotally connected to a plurality of shields, and the plurality of wings and the plurality of shields are operable to extend laterally away from the elongated body, in a deployed position, as the actuator rod is moved in a proximal direction with respect to the elongated body,
- wherein the plurality of wings each include an opening to allow passage into a suture retrieval space defined between the one each of the plurality of wings and plurality of shields when extended away from the elongated body in the deployed position,
- wherein a distal end of the suture grasper is insertable through the at least one needle guide lumen and through the opening of the plurality of wings while the plurality of shields are extended laterally away from the elongated body in the deployed position, and
- wherein the plurality of shields, in the deployed position, prevent inadvertent needle perforation of organs, vessels, or other tissues by the suture grasper as the suture grasper is inserted through the opening of the plurality of wings.
