A suture anchor assembly and methods of use will now are disclosed for the repair of human or animal tissue defects. The suture anchor assembly is capable of being inserted into a tissue or bone while also being able to create an expanded profile when subjected to a retrograde force. This expanded profile anchors the assembly into the tissue or bone by a changing of position of elements of the assembly relative to other assembly elements. Embodiments of the suture anchor assembly and methods are capable of precisely positioning assembly elements in the tissue or bone to effectively repair the defects.

Methods for repairing a meniscus, and particularly a torn meniscus. A method of repairing a meniscus may include using a suture passer to pass a suturing element from the region between the superior surface of the meniscus and the femoral condyle, through the meniscus tissue, into the region between the inferior surface of the meniscus and the tibial plateau, across the inferior surface of the meniscus, and back to the superior surface of the meniscus, without deeply penetrating the posterior capsular region of the knee. Equivalently, the suture element may be passed from the inferior surface of the meniscus to the superior surface and back to the inferior surface.

Method of Suturing Tissue

Автор: Chin Wai Ngal, Hasan Jafar Syed, Kobylewski Gary Michael
Принадлежит:

A medical device for installing sutures to close an incision in tissue or human skin is disclosed. The suturing device may provide first and second arcuate needles. Once properly positioned, the first and second arcuate needles are driven through the sub-dermal layer, or alternatively through a superficial surface, of two sections of skin to be joined. This is done in arcuate fashion and at identical and symmetrical rates of angular displacement. In so doing, the sections of skin are pushed toward one another thus assuring horizontal and vertical alignment of the two sections of skin. During the driving or retraction process of the first and second arcuate needles, a suture is positioned within both the first and second sections of skin and transformed from a planar or a multi-planar serpentine orientation to a helical orientation. The resulting suturing process is thus much faster than conventional or manual suturing and results in superior wound approximation/alignment that will lead to decreased scarring compared to prior art devices. 110-.

An instrument for delivering a transfascial suture , the instrument comprising:a handle;an elongated shaft extending from the handle and including a distal end;at least one needle moveable to an extended position beyond the distal end of the shaft, the at least one needle having a sharp end adapted to pierce a soft tissue repair prosthetic and abdominal wall tissue;at least one shield adapted to shield the sharp end of the at least one needle from contact therewith when the needle is moved to the extended position, at least one of the shield and the needle being movable relative to the other of the shield and the needle between a first position to shield the sharp end and a second position to expose the sharp end; anda drive mechanism adapted to advance the at least one needle to the at least one extended position.2. The instrument according to claim 1 , wherein the at least one shield includes an outer sheath adapted to shield the sharp end and expose the sharp end.3. The instrument according to claim 2 , wherein the outer sheath includes a plurality of shield portions that extend from a distal end of the outer sheath to shield the sharp end ...

A suture manipulating instrument for passing and retrieving suture through a tissue includes a handle mechanism, an elongate shaft extending from the handle, and a working distal end. The working distal end includes a needle body, a lumen defined by the needle body, a tissue penetrating distal tip, and a lateral slot. A preformed inner member is movably disposed within the lumen of the needle. The handle mechanism is used to extend the wire from the lateral slot of the needle, and to retract the wire into the lateral slot, allowing the working end of the instrument to grasp and manipulate suture by pinning and/or trapping the suture against the needle. In embodiments the inner member is further retracted within the needle lumen, drawing a length of suture into the needle lumen. The suture is subsequently ejected from the needle lumen to form a suture loop. 1. An instrument for manipulating and passing suture through a tissue , said instrument comprising:a handle end and a needle defining a distal endthe needle comprising a lumen extending therethrough, the needle terminating with a distal beveled end, and a second beveled portion on an outer surface of the needle configured to form a point on a distal most edge of the needle, and wherein the needle further comprises a cutoff extending proximally from the distal beveled end and along the needle, the cutoff terminating with a shoulder; i) a retracted configuration in which the entire inner member is spaced proximally from the cutoff to clamp the suture therebetween;', 'ii) an open configuration in which a distal portion of the of the inner member extends from the cutoff of the needle to capture the suture; and', 'iii) an intermediate configuration in which the inner member and the needle encircle a section of suture such that the suture is slidably held therebetween., 'an elongate inner member axially moveable within said lumen and relative to said cutoff, said inner member and needle cooperating together to move ...

A suture grasping and passing device having a handle with an elongate tubular needle defining a lumen therein and extending from the distal end of the handle and having a pointed forward distal tip for puncturing soft tissue. A lateral radially open suture capture notch is provided in the tubular needle adjacent the pointed distal tip and defines a mouth open to the needle lumen. The notch mouth is contoured to receive a suture therein transversely across the mouth and an elongate gate member is slidably received for axial movement within the lumen whereby the gate member may be advanced in a forward direction to entirely close off an outer radial apex portion of the suture capture mouth to capture a suture under the gate member within the mouth of the notch. 1. A suture grasping and passing device comprising:a handle;an elongate tubular needle defining a lumen therein and extending from a distal end of the handle and having a pointed forward distal tip for puncturing soft tissue;a radially open suture capture notch in said tubular needle adjacent said pointed distal tip and defining a mouth open to the lumen of said tubular needle and contoured to receive a suture therein transversely across said mouth; andan elongate gate member slidably received for axial movement within said lumen of said needle whereby said gate member may be advanced in a forward direction for thereby closing off an outer radial apex portion of said mouth to capture a suture thereunder in said mouth.2. The suture grasping and passing device of claim 1 , wherein said elongate gate member is a flexible wire.3. The suture grasping and passing device of claim 2 , wherein the forward distal end of said tubular needle is curved.4. The suture grasping and passing device of claim 1 , wherein said mouth of said notch is contoured to have a rearward facing reverse curvature providing a recessed curvature in the forward edge of said mouth for hooking and retaining a suture therein as said needle is ...
