Staple Or Clip Patents (Class 606/75)
  • Patent number: 5573547
    Abstract: A method of fixation for use within animal and human bodies provides for the insertion of brushes, of cylindrical and conical designs, into openings wherein bristles of the brushes are deflected by walls of the openings such that the brushes are locked in place and resist forces applied thereto. An embodiment of the invention includes boring a hole into a cancellous bone structure and inserting a brush into the hole. The hole is of a smaller diameter than the brush and is locked in the hole by the bristles. Tissue, such as tendon, may then be attached to material affixed to an end of the brush. Another embodiment of the method includes insertion of a brush into a blood vessel such that the blood flow is either occluded or strained by the bristles of the brush.

  • Patent number: 5571104
    Abstract: An anchor for attaching an object within a tunnel extending through a workpiece such as a bone or a bone-like structure, and a method for using the same. The anchor includes a body and a plurality of barbs located in circumferentially spaced relation about the body. The barbs are formed of a material which may be elastically deformed from a normal configuration wherein the outer ends of the barbs extend radially outwardly of the body toward a configuration wherein the barbs are located generally parallel to the longitudinal axis of the body. A diametrical opening in the front portion of the anchor is provided for engagement by a length of cord-like material such that the anchor may be pulled into a bone tunnel, and an opening in the rear portion of the anchor is provided for attaching either a ligament, tendon or the like to the anchor, or for grasping a bone plug or similar rigid object attached to a free end of the ligament, tendon or the like.

    Abstract: A fastener adapted to expand into bone has a tubular body having a longitudinal opening therethrough with a stop within the opening. The body has a head at one end and a longitudinal slot extends through the body near the other end to form ribs that expand radially when the body is compressed. A puller projects through the opening in the rivet and has a head that engages the other end to compress the rivet when the puller is pulled through the body. An annular recess is formed in the puller near the head and the other end of the body is crimped into the recess to aid expansion of the ribs.

  • Patent number: 5441502
    Abstract: A system and method for re-attaching soft tissue to bone. In its preferred embodiment, the system comprises pin means, sleeve means, driver means, suture anchor means and suture anchor installation tool means. In use, the soft tissue is placed against the surface of the bone in its desired re-attachment position. Then the pin means is passed through the soft tissue and into the bone to securely fix the pin means (and hence the soft tissue) to the bone. Then the patient's anatomy is manipulated as needed to determine if the soft tissue has been properly positioned relative to the bone. If the soft tissue is properly positioned, the surgeon proceeds to the next step in the procedure; if not, the pin means is removed and the tissue positioning operation repeated until the soft tissue has been positioned in the desired location. Next, the sleeve means is slid telescopically over the pin means, passed through the soft tissue and then, using the driver means, drilled into the bone.

  • Patent number: 5236445
    Abstract: A bone anchor, for securing a suture to a bone, has an open proximal end and a body that tapers to a solid distal tip. The anchor is placed deep in a borehole in a bone using an insertion instrument that is inserted through the open proximal end of the anchor. The tip of the instrument is a spherical knob that snaps into a corresponding recess inside the anchor. The instrument has an oval cross-section that does not bear against the walls of the anchor during insertion. Once the anchor is in place, however, the anchor is expanded by rotating the instrument to bring the exterior of the instrument into contact with the walls of the anchor. The anchor is free to pivot about the spherical knob on the instrument, which allows the anchor to orient itself to the shape and size of the borehole.

A strand of suturing thread (22) extends through a suture receiving opening (24) in the tip (16) of the anchor. The method of the present invention employs the suture anchor (10) and includes the steps of forming a hole (36) in a bone (38) and inserting the suture anchor (10) to a desired depth in the hole (36) in the bone (38) using an inserter device (100). Suturing thread ( 22) extends from the suture receiving opening (24) in the tip and along the length of the walls (27,28) out of the hole (36) in the bone (38). An anchor spreader (130) is used to firmly seat the anchor (10) in the hole (36).

  • Patent number: 5209756
    Abstract: A fixation device for securing a prosthetic ligament to a bone and which comprises a bone staple having a head portion by means of which the staple can be driven into the bone, and a pair of legs extending from the head and having ends engageable into the bone, characterized by a stirrup for guiding the driving movement of the staple and arranged also to cooperate with the staple in order to enable the prosthetic ligament to engage the staple and the stirrup and to be securable to the bone upon completion of driving of the staple into the bone, the stirrup comprising two generally parallel side portions which define guides to receive the legs of the staple and to guide the driving movement of the legs, and also defining an aperture through which the ligament can be taken prior to securement of the ligament to the bone.

  • Patent number: 5207679
    Abstract: A system for attaching an object to a workpiece including an anchor assembly and an installation tool is provided. The anchor assembly includes a body and at least two barbs. The body has a first portion having a first end, a reduced second portion having a second end and a middle portion connecting the first and second ends of the first and second portions respectively. The barbs extend from the first end of the first portion axially and radially outwardly to outer ends located radially outwardly of an axial projection of the maximum transverse cross-section of the first portion. Each barb is curved in its normal unstressed state, but is capable of being elastically deformed into longitudinal channels in the middle portion of the anchor assembly. The anchor assembly is deployed in a hole in the workpiece by an installation tool which is adapted to receive the reduced second portion of the anchor assembly in its distal end.

  • Patent number: 5167665
    Abstract: An object is attached to a bone by using blind rivets. The blind rivets can be set from the outside of the bone. Each blind rivet has a body, with a head on one end, and a mandrel extending from the head end of the body. A hole is formed in the bone. The rivet is inserted through the object and into the bone through a hole in the bone cortex. The rivet is set by pulling on the mandrel with the rivet gun. The rivet secures the object to the proximal cortex layer of the bone. The method is used to attach objects such as plates and hip sockets to bone. In addition, the rivet can be provided with serrations on the head, wherein the rivet attaches soft tissue, such as muscle tendons, to bone.

    Abstract: A bone anchor (10) for securing a suture to a bone (38). The bone anchor (10) has a tip (16) at its distal end (18) and at least one resilient wall (27) extending to a trailing end (20) of the body (12) of the anchor. The wall (27) has a ridge (14), or barb, formed on an outer surface. The ridge (14) defines an edge (34) that digs into a hole (36) in the bone (38) in which it is positioned. A strand of suturing thread (22) extends through a suture receiving opening (24) in the tip (16) of the anchor. When tension is applied to the suturing thread (22), it causes the ridge (14) to dig into the walls of the hole (36) in the bone (38). Two resilient walls (27,28) are preferably provided which include an annular ridge-shaped barb (14). The two resilient walls 27, 28 scissor outwardly upon application of tension to the suturing thread. The tip (16) is generally frustoconical with a rounded leading end.
