International Classification:

A61B 17/10

US Classification:

606139, 606153, 623 2372

Abstract:

A method for closing an opening in tissue, such as an opening in heart tissue, may include moving a housing to a location in proximity to the opening, registering the housing to the opening, and deploying a staple from the housing into tissue in proximity to the opening. The opening in heart tissue may be a patent foramen ovale, atrial septal defect, or other opening. The housing may be moved to the opening through the vasculature, utilizing a guidewire, steering catheter, or other mechanism.

International Classification:

A61B 17/072

US Classification:

606139, 227 19, 2271761, 227 82, 606219

Abstract:

A method for surgically stapling tissue may include providing staples in a first configuration, plastically deforming at least one staple to a second configuration different from the first configuration; and then plastically deforming at least one staple to a third configuration different from the first configuration and the second configuration. The deformation of a staple from the first configuration to the second configuration may be performed by splaying the staple. The staple may be splayed by a splay arm or other suitable structure or mechanism.

International Classification:

A61B 17/10

US Classification:

606139

Abstract:

An exemplary medical apparatus insertable into the vasculature of a patient at an insertion point for treating a defect in the heart, may include an elongated, flexible driver sufficient in length to extend from the insertion point to the defect in the heart; and a staple frangibly attached to the distal end of the driver. Another exemplary medical apparatus may include a catheter sufficient in length to extend from the insertion point to the patent foramen ovale; a housing attached to the distal end of the catheter; a driver extending into the housing; and a staple frangibly attached to the driver. Another exemplary medical apparatus may include a steering catheter sufficient in length to extend from the insertion point to the patent foramen ovale; an end effector attached to the distal end of the steering catheter, the end effector having a cross-section sufficiently small to allow it to be moved through the vasculature to the patent foramen ovale; and a staple held by the end effector, wherein the staple is frangibly separable from and deployable out of the end effector to close the patent foramen ovale.

International Classification:

A61B 17/10

US Classification:

606139

Abstract:

One method for closing an opening in tissue may include providing a substantially continuous solid staple having a plurality of tines and a longitudinal centerline, plastically deforming the staple to a splayed configuration; penetrating at least one tine into tissue in proximity to the opening; and plastically deforming the staple to a closed configuration. Another method for closing an opening in tissue may include providing a staple having a plurality of tines; plastically deforming the staple to a splayed configuration by applying force in the distal direction against a proximal surface of the staple; penetrating at least one tine into tissue in proximity to the opening; and plastically deforming the staple from the splayed configuration to a closed configuration by applying force in the distal direction against a proximal surface of the staple.

International Classification:

US Classification:

2271761, 227 19, 227 82, 606139, 606219

Abstract:

One example of a surgical stapler may include a pusher, at least one generally planar staple, where the pusher holds at least one staple, and a splay arm that includes spaced-apart splay fingers extending generally distally, where at least one splay finger includes a splay tip extending therefrom, and where relative motion of said pusher and said splay fingers causes said at least one said splay tip to engage and then splay at least one said staple. Another example of a surgical stapler may include a plurality of staples positioned out of contact with one another; a pusher that engages each staple; and at least one splay tip, each splay tip configured to contact a distal surface of the distalmost staple. Another example of a surgical stapler may include a plurality of staples, a pusher that holds the staples, the pusher having a longitudinal axis and being slidable longitudinally both proximally and distally substantially along that longitudinal axis, where the pusher is substantially constrained against motion away from the longitudinal axis; and a splay arm movable in a direction away from the longitudinal axis, from a position in which the splay arm contacts one staple to a position in which the splay arm no longer contacts that staple.

606144, 606139

Abstract:

Methods, systems, devices and assemblies are provided for treating a patient by: making an incision or puncture though the patient's skin over the abdominal cavity; establishing an initial tract through an opening formed by the incision or puncture; advancing an instrument through the tract; contacting a distal end portion of the instrument against an inner surface of the abdominal cavity; driving at least one stitching needle through the inner surface of the abdominal cavity, continuing the driving until the at least one stitching needle exits the inner surface of the abdominal cavity, anchoring a suture carried by each of the at least one stitching needle to a suture anchor at an exit location, respectively; and applying tension to each of the sutures.
