Method and apparatus for tissue fastening with single translating trigger operation
First Claim
1. A device for gathering and securing opposed tissue with a fastener comprising:
- an applicator assembly operably configured to deploy a fastener having a generally symmetric u-shaped configuration in a first plane defined by a pair of tips and a body of the fastener, the applicator assembly including a head portion adapted to be positioned in an interface between opposed tissue;
a tissue manipulation assembly operably configured to move from a relaxed position to a grasping position in a second plane generally transverse to the first plane; and
a translating trigger assembly operably coupled to the applicator assembly and the tissue manipulation assembly, the trigger assembly operably configured to move from a relaxed position, through a first position, to a second position along a third plane that is generally transverse to both the first plane and the second plane,such that manual operation of the translating trigger assembly from the relaxed position through the first position along the third plane causes the tissue manipulation assembly to move in the second plane to gather at least portion of the opposed tissue, said opposed tissue being positioned on either side of the head portion without overlapping the opposed tissue along the third plane, and such that continued manual operation of the translating trigger assembly from the first position on to the second position along the third plane causes the applicator assembly to deploy the fastener into the opposed tissue along the first plane.

Abstract
A mechanical device and method for gathering and securing tissue with a fastener. The device includes an applicator assembly configured to deploy a fastener in a first direction, a tissue manipulation assembly configured to move from a relaxed position to a grasping position in a second direction transverse to the first direction, and a translating trigger assembly coupled to the applicator assembly and the tissue manipulation assembly. The trigger assembly is configured to move from a relaxed position, through a first position, to a second position along a third direction transverse to the first and second direction. Operation of the trigger assembly from the relaxed position through the first position along the third direction causes the tissue manipulation assembly to move in the second direction to gather a portion of the tissue. Continued operation of the trigger assembly along the third direction causes the applicator assembly to deploy the fastener.

10. A method for gathering and securing opposed tissue with a fastener comprising:
-
providing a fastener apparatus having; an applicator assembly operably configured to deploy a fastener having a generally symmetric u-shaped configuration in a first plane defined through a widest aspect of the fastener; a tissue manipulation assembly operably configured to move from a relaxed position to a grasping position in a second plane generally transverse to the first plane; and a translating trigger assembly operably coupled to the applicator assembly and the tissue manipulation assembly, the trigger assembly operably configured to move from a relaxed position, through a first position, to a second position along a third plane that is generally transverse to both the first plane and the second plane; positioning at least a portion of the applicator assembly in an interface between the opposed tissue; advancing the trigger assembly from the relaxed position through the first position along the third plane wherein the tissue manipulation assembly moves in the second plane to gather a portion of the tissue; and moving the trigger assembly from the first position to the second position along the third plane wherein the applicator assembly deploys the fastener into opposed tissue along the first plane. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A device for gathering and securing opposed tissue with a fastener comprising:
-
means for deploying a fastener having a generally symmetric u-shaped configuration in a first plane defined through a widest aspect of the fastener, the means for deploying the fastener is adapted to be position in an interface between opposed tissue; means for capturing tissue in a second plane generally transverse to the first plane; means for moving a trigger from a relaxed position, through a first position, to a second position along a third plane that is generally transverse to both the first plane and the second plane, such that movement of the trigger from the relaxed position through the first position along the third plane causes the means for capturing tissue to move in the second plane to capture at least portion of the opposed tissue, said opposed tissue being position on either side of the means for deploying the fastener without overlapping the opposed tissue along the third plane, and such that continued movement of the trigger means from the first position on to the second position along the third plane causes the device to deploy the fastener into the opposed tissue along the first plane.

18. A method for forming an interrupted closure of opposed tissue on adjacent sides of a skin wound comprising:
-
providing an apparatus having a plurality of fasteners, wherein the length of each of the plurality of fasteners is shorter than a longitudinal length of the skin wound; positioning at least a portion of the fastener apparatus in an interface between the opposed tissue; approximating the opposed tissue without overlapping the opposed tissue along the longitudinal length of the skin wound; deploying a first fastener into subcutaneous tissue in a first direction along the longitudinal length of the skin wound without penetrating the epidermis of the tissue; and deploying a second fastener into subcutaneous tissue in the first direction without penetrating the epidermis of the tissue such that an interrupted closure is formed whereby the plurality of fasteners are located discretely along the longitudinal length of the skin wound so as to prohibit communication of infectious material along the longitudinal length of the skin wound. - View Dependent Claims (19)
