Definitions

  • the present invention relates generally to suturing methods and apparatus.
  • the present invention relates to suturing devices for adjustably anchoring sutures.
  • Suture anchors are commonly used to retain sutures within a region of tissue and/or bone.
  • Conventional suture anchors are typically made of biocompatible materials and are used to bind openings or tears in the soft tissue of the body. These wounds are approximated and held by sutures which are typically tied together by knotting. This relatively simple task, however, requires much concentration and the use of both hands by the physician or practitioner in ensuring a good tight seal.
  • tensioning adjustments may need to be made to a suture during or after the suturing procedure to add or remove slack in the suture either due to the movement of tissue and/or bone or to enhance the efficacy of the soft tissue coaption.
  • tissue and/or bone or to enhance the efficacy of the soft tissue coaption.
  • a physician may prefer to use the suture as a method of anchoring a region of soft tissue to the bone wherein the bone anchor location is at a remote location to the point of soft tissue fixation.
  • a suture is inserted into a passage within the anchor which is then positioned in a patient's body.
  • the suture extends into the passage within the anchor.
  • subsequent adjustments to the suture are made difficult because of the suture and anchor placement within the bone.
  • U.S. Pat. No. 6,270,518 (Pedlick et al.) describes a wedge shaped suture anchor and a method of implantation.
  • the anchor is fabricated by angular cuts and defines bore holes through which sutures may be passed. Both the anchor and the suture are seated within the body and bite into the walls of the bone to provide the anchoring force.
  • this device is also difficult to adjust for suture tensioning and still requires two-handed operation.
  • U.S. Pat. No. 6,241,749 (Rayhanabad) describes an adjustable tension device for sutures which comprises a body through which sutures may be knotted at the top of the body.
  • the body has a plurality of flexible legs extending outwardly and downwardly to rest on the body of the patient.
  • U.S. Pat. No. 6,015,428 (Pagedas) describes an integrally formed suture and suture lock which comprises a self-adjusting suture lock and a thread retaining opening.
  • the suture lock in part, comprises tongues having a conical section shape which lock onto a suture passed therethrough. The springiness and engagement of each tongue against the suture prevents the suture from being withdrawn. This adjustability, however, allows only for the tensioning of a suture and not complete adjustability.
  • a implantable suture anchor is described below which is capable of accommodating various suture sizes and which allows for the repeated adjustment of suture lengths without the need for the tying of knots.
  • One variation of the suture anchor comprises a shaft portion having a first diameter and a head portion having a second diameter which is preferably larger than the first diameter.
  • the shaft preferably defines a chamfered distal end to facilitate positioning and placement within bone and the shaft also preferably defines radially extending tabs along the outer surface of the shaft. Any number of tabs may be defined and are used to provide an enlarged local diameter to aid in preventing the anchor from being pulled out of the bone or rotating within the bone.
  • suture anchor may comprise a shaft portion having a first diameter, a post portion having a second diameter, and a head portion having a third diameter.
  • the post portion, around which the suture may be wrapped, may have the smallest cross section relative to the other portions and it may assume, e.g., a circular, oval, or oblong shape.
  • the distal end of the post portion may include one or several additional posts or pegs that may protrude distally for insertion into additional holes bored into the bone. These additional posts or pegs may key the anchor within the bone hole to aid in preventing rotation of the anchor within the hole when implanted.
  • an optional channel may be circumferentially defined along a portion of the the post to further define a region within which the suture may be securely wrapped about.
  • the head may have a through hole defined to extend perpendicularly through the anchor relative to a longitudinal axis defined by the head and shaft. Furthermore, the head also defines an aperture which preferably extends at least partially into the head towards the longitudinal axis defined by the anchor.
  • This aperture may be in the form of a notch or other forms that allow for suture positioning and stability within the device.
  • the notch may be located anywhere along the head. The notch may further define an edge which is angled through the thickness of the head to help facilitate retention of a suture.
  • the suture anchor may be fabricated as a singular, integral device preferably formed from biocompatible materials such as metals, e.g., stainless steels, nickel alloys, titanium alloys, etc., from polymeric materials such as polyglycolide, polylactide, etc., which may optionally be bioabsorbable as well, or from natural materials such as bone.
  • the suture anchor may alternatively be fabricated as two separate halves or as two joined halves assembled as a single piece. Such a separable anchor may be completely separable or it may be partially connected via a connecting bridge. In either case, the separable anchor preferably forms a similar configuration when fully assembled as the integral anchor.
  • each half of the separable anchor assembly When assembled, each half of the separable anchor assembly may be brought together pivotally about the connecting bridge such that each adjoining surface comes into contact with one another.
  • the assembly When each half is brought together, the assembly may be held together by a variety of mechanical fastening mechanisms, e.g., locking posts, interfitting tabs, adhesives, etc.
  • a suture Prior to use, a suture may be pre-loaded within the through hole either by threading it through or by placing it in the through hole halves, if the separable anchor is used, prior to anchor assembly. This preliminary step eliminates the need for separately threading the suture through a small hole.
  • a hole may initially be drilled at a desired location for the anchor.
  • the anchor may be placed within an anchoring hole which has been drilled or bored into the anchoring region, e.g., bone, and the suture may be subsequently fed through the through hole.
  • the shaft is preferably press fit or friction fitted into the hole.
  • the hole has a diameter which is slightly smaller than or the same as the diameter of the shaft or tabs.
  • the anchor may be positioned within the hole such that through hole is aligned along the direction of the tensile load created by the tissue pulling on the suture.
  • the notch may be positioned to face away from the direction of the tensile load.
  • the anchor is also preferably positioned such that the longitudinal axis defined by the anchor is positioned perpendicularly relative to the bone surface.

  • the tension on the suture may be adjusted as necessary by pulling the free end of the suture to adjust accordingly.
  • the suture free end may be wrapped about the shaft or post in or between the head and the bone surface.
  • the suture free end may be wrapped about the shaft a number of times ranging anywhere from 45° to more than 360° relative to the longitudinal axis and the through hole and then the free end may be secured within the notch.
  • the suture free end may be pulled up and out of the notch, unwrapped from the shaft, and the tension may be readjusted as necessary. Afterwards, the suture free end may be resecured in the manner described above. [0017] Alternatively, the suture may be affixed within the body of the anchor by various fastening methods prior to positioning. Once the suture has been fixed within the anchor, the suturing, tensioning, and retensioning of the tissue may be accomplished in the same manner as described above.
  • the suture may be attached to the tissue and the free end of the suture may be loaded within the through hole and simply wrapped about the anchor to hold the tissue in place. Again, the free end may simply be unwrapped and adjusted accordingly and then rewrapped as necessary.
  • Other variations on methods of anchoring and the suturing anchors themselves which are obvious variations are intended to be within the scope of this application.
  • the present methods and anchor variations obviate the need for tying knots in the sutures or the use of other conventional methods to obtain a secure fit; moreover, suturing is simplified since the physician or practitioner can use a single hand for adjustments and readjustments as necessary.

Abstract

La présente invention concerne des éléments d'ancrage réglables pour suture. Les éléments d'ancrage pour suture sont compatibles avec différents types de sutures et permettent un ajustage répété des longueurs de suture sans impliquer la formation de points de suture. Les éléments d'ancrage présentent une partie tête, une partie tige et un orifice de passage s'étendant perpendiculairement entre celles-ci. La partie tige est implantée à l'intérieur de l'os et la suture est fixée aux tissus et est passée à travers l'orifice de passage. La tension est ajustée jusqu'à un niveau souhaité et l'extrémité libre de la suture est fixée à l'élément d'ancrage. La suture est fixée en l'enveloppant autour de la tige entre la partie tête et la surface osseuse et en la fixant à l'intérieur d'une encoche pratiquée dans la tête. Pour réajuster la tension, l'extrémité libre de la suture est sortie de l'encoche en étant tirée vers le haut, puis déroulée de la tige, et la tension est réajustée si nécessaire. Ensuite, l'extrémité libre de la suture est à nouveau fixée dans l'encoche.
