Abstract
Devices and methods for closure of apertures in tissue (e.g., defects in fascial tissue) are generally provided. Closure of apertures in tissue, e.g., using sutures and patch closures, are common surgical operations. In some aspects, methods and devices for using tissue grippers to engage tissue portions, and subsequently biasing the tissue grippers and tissue portions towards one another by changing a configuration of a lock are generally provided. In other aspects, methods and devices for measuring a retraction force applied by tissue grippers to tissue portions are generally provided.
Claims27
A tissue closure device, comprising:
- a first tissue gripper;
- a second tissue gripper;
- a spring operatively coupled to the first tissue gripper and the second tissue gripper;
- a lock configured to retain the first tissue gripper and the second tissue gripper in an extended configuration in a locked configuration, wherein the spring is configured to bias the first tissue gripper and the second tissue gripper towards a retracted configuration when the lock is in an unlocked configuration;
- and
- a housing including a first housing portion and a second housing portion, wherein the first tissue gripper is operatively coupled to the first housing portion and the second tissue gripper is operatively coupled to the second housing portion, wherein at least a portion of the second housing portion is configured to slide into an interior volume of the first housing portion, and wherein the second tissue gripper is configured to move with the second housing portion in the same direction as the second housing portion.
3 more elements
A method for closing an aperture in tissue, the method comprising:
- retaining a first tissue gripper engaged with a first tissue portion and a second tissue gripper engaged with a second tissue portion in an extended configuration;
- changing a lock from a locked configuration to an unlocked configuration to release the first tissue gripper and the second tissue gripper from the extended configuration;
- biasing the first tissue gripper towards the second tissue gripper to move the first tissue gripper and the first tissue portion towards the second tissue gripper and the second tissue portion, wherein the first tissue gripper is operatively coupled to a first housing portion and the second tissue gripper is operatively coupled to a second housing portion;
- and
- sliding at least a portion of the second housing portion into an interior volume of the first housing portion when the first tissue gripper is biased towards the second tissue gripper, wherein the second tissue gripper is configured to move with the second housing portion in the same direction as the second housing portion.
2 more elements
A tissue closure device, comprising:
- a first tissue gripper configured to apply a first clamping force to a first tissue portion;
- a second tissue gripper configured to apply a second clamping force to a second tissue portion;
- a spring operatively coupled to the first tissue gripper and the second tissue gripper;
- a housing including a first housing portion and a second housing portion, wherein the first tissue gripper is operatively coupled to the first housing portion and the second gripper is operatively coupled to the second housing portion, wherein the spring is configured to bias the first tissue gripper and the second tissue gripper from an extended configuration towards a retracted configuration;
- and
- a force indicator configured to visually indicate a retraction force applied by the first and second tissue grippers to the first tissue portion and the second tissue portion,
- wherein at least a portion of the second housing portion is configured to slide into an interior volume of the first housing portion, and wherein the second tissue gripper is configured to move with the second housing portion in the same direction as the second housing portion.
4 more elements
A method for closing an aperture in tissue, the method comprising:
- retaining a first tissue gripper engaged with a first tissue portion by a first clamping force and a second tissue gripper engaged with a second tissue portion by a second clamping force in an extended configuration;
- biasing the first tissue gripper towards the second tissue gripper to move the first tissue gripper and the first tissue portion towards the second tissue gripper and the second tissue portion, wherein the first tissue gripper is operatively coupled to a first housing portion and the second tissue gripper is operatively coupled to a second housing portion;
- visually indicating a retraction force applied by the first and second tissue grippers to the first and second tissue portions using a force indicator;
- and
- sliding at least a portion of the second housing portion into an interior volume of the first housing portion when the first tissue gripper is biased towards the second tissue gripper, wherein the second tissue gripper is configured to move with the second housing portion in the same direction as the second housing portion.
