  • Patent number: 11766321
    Abstract: Described herein are breast implant fixation devices for use in breast reconstruction and breast augmentation. Novel wraps are designed to avert lateral displacement and bottoming out of breast implants, reduce capsular contraction and implant extrusion, eliminate skin indentations and ripples caused by breast implants, and reduce or eliminate palpability. The wraps are adapted to securely fold around the breast implants, limiting relative movement between the wrap and breast implant and reducing wrinkles. Tissue in-growth into the wraps limits movement of the wrap-breast implant assembly and thereby limits movement of the breast implant.

  • Patent number: 11717298
    Abstract: A surgical clamp for aligning the margins of incised or wounded tissue has jaws with parallel clamping faces, and a handle for manipulating the clamp to align the margins of the tissue. The jaws are in a normally closed position, however they can be opened by compressing the handle to open the jaws. Prongs project from the inferior surface of the jaws. The clamp is positioned in a desired position over the margins of a wound to be closed, the prongs engage the margins of the wound to be aligned, and the jaws are closed by releasing compressive force on the handle. As the jaws close the prongs help move the tissue into alignment. Suture guide slots through the jaws assist in the placement of precisely placed sutures across the incision. The disclosed surgical clamp is particularly suited for selectively closing and reopening surgical incisions, such as a sclerotomy incision in the eye. Methods are disclosed for using the clamp during intraocular and other surgical or minimally invasive procedures.

  • Patent number: 10448979
    Abstract: Described is a new bone healing method and class of bone fixation implants that change shape once implanted so as to minimize non-healing and speed the bone healing process. The bone fixation method involves shape changing implants that continuously hold the bones in apposition so that a gap does not form. Gaps in time allow non-bony tissue to infiltrate and stop healing. Furthermore, the implants actively compress bone to increase bone mass and strength. Bone cell pressure due to compression and electrical current flow due to bone deformation act to stimulate healing. The new implant designs also provide a scaffolding to conduct bone through the implant and across the healing bone interface. The methods and designs are applicable to but not limited to use for bone screws, plates, staples, rods, cylinders and external fixation devices.

The actuation device includes an actuation element (21) which can be actuated by the user device, moved longitudinally into the catheter tube (1), and acts on the first front clip (3), as well as a control part (25) which converts the actuation force of the actuation element into an opening movement of the legs (5) of the clip (3).

  • Patent number: 7608091
    Abstract: The methods, devices, and systems are provided for performing endovascular repair of atrioventricular and other cardiac valves in the heart. Regurgitation of an atrioventricular valve, particularly a mitral valve, can be repaired by modifying a tissue structure selected from the valve leaflets, the valve annulus, the valve chordae, and the papillary muscles. These structures may be modified by suturing, stapling, snaring, or shortening, using interventional tools which are introduced to a heart chamber. Preferably, the tissue structures will be temporarily modified prior to permanent modification. For example, opposed valve leaflets may be temporarily grasped and held into position prior to permanent attachment.

    Abstract: A surgical staple including at least two deformable members which can be bent upon contacting an anvil of a surgical stapler. In various embodiments, at least a portion of the deformable members can include a non-circular cross-section which can dictate the direction and manner in which the deformable members are bent. In at least one embodiment, the non-circular cross-section can include a flat portion which can cause the deformable members to bend in the direction of the flat portion. In various embodiments, the at least two deformable members can be connected by a dissolvable or bioabsorbable crown. In at least one various embodiment, the crown can dissolve and can, depending on the cross-sectional geometry of the deformable members, reduce the force or pressure applied to soft tissue captured within the staple by the bent deformable member.

    Abstract: A method for closing an opening in a wall of a body lumen wherein an elongate member is advanced into the body lumen and a distal portion of an obturator is positioned distally beyond the distal end of the elongate member within the body lumen and in which one or more expandable elements on the distal portion of the obturator are expanded. The obturator is then withdrawn until the expandable elements contact the wall of the body lumen and a clip having tines is advanced over the elongate member until the tines penetrate the wall of the body lumen. The tines and the expandable elements are offset from one another. The elongate member is withdrawn from the body lumen and the clip substantially closes the opening in the body lumen.

  • Patent number: 6916327
    Abstract: A surgical staple for use in creating an everted anastomosis of at least two anatomical structures includes a bendable staple body. At least two evening elements protrude from the staple body. Spacing elements and a penetrating element also are provided. In use, the evening elements and spacing elements are apposed, and inner layers of the anatomical structures are held together to form an evened anastomosis. The evening platforms are disposed on an outer radius of the closed staple, and the penetrating element is disposed on a different, inner radius, to ensure that the penetrating element is excluded from the lumen of the anastomosis. Embodiments of the invention substantially ensure intima-to-intima approximation completely circumferentially at the anastomotic site, with no portion of cut tissue edges, suture or staple exposed to the lumen of the anastomosis. Cut tissue edges, as well as the staple, are completely extra-lumenal. Related methods provide similar advantages.

  • Patent number: 6913607
    Abstract: A self-closing fastener is described that comprises a clip passable through a tissue opening. The fastener is adapted for holding by a mechanism in an open configuration for passing through the tissue, followed by releasing the fastener from the holding mechanism, allowing the clip to remain in the tissue in a shape that can clip two or more locations on the tissue. The fastener and delivery devices are particularly useful for tissue approximation, such as anastomosis. When used for anastomosis, the inventive clips provide intima-to-intima contact with a minimal amount of intraluminal exposure.

  • Patent number: RE49667
    Abstract: Described is a new bone healing method and class of bone fixation implants that change shape once implanted so as to minimize non-healing and speed the bone healing process. The bone fixation method involves shape changing implants that continuously hold the bones in apposition so that a gap does not form. Gaps in time allow non-bony tissue to infiltrate and stop healing. Furthermore, the implants actively compress bone to increase bone mass and strength. Bone cell pressure due to compression and electrical current flow due to bone deformation act to stimulate healing. The new implant designs also provide a scaffolding to conduct bone through the implant and across the healing bone interface. The methods and designs are applicable to but not limited to use for bone screws, plates, staples, rods, cylinders and external fixation devices.
