SUTURE ANCHOR
When ligaments or tendons detach from associated bone, or become damaged by way of being torn, surgical intervention can be used to assist repair and reattachment (restoration). An anchor in the cortical portion of the bone is provided which is used to secure a suture with respect to the bone wherein the suture is attached at one end to a tendon or other portion of the body and the free end is secured to the anchor without the use of a knot. An arthroscopic transosseous knotless suture anchoring arrangement for holding a suture includes, a hollow body for at least partial insertion into a cortical portion of a hone and a holding dement having an elongate body sized for fitment with and within the hollow of the body for holding a suture located in the hollow body with respect to the cortical portion of the bone.
1 . An arthroscopic transosseous knotless suture anchoring arrangement for holding a suture with respect to a cortical portion of a bone, comprising:
a hollow body for at least partial insertion into a cortical portion of a bone; and
a holding element having an elongate body sized for fitment with and within the hollow of the body tor holding a portion of a suture located in the hollow body with respect to the cortical portion of the bone.
2 . An arthroscopic transosseous knotless suture anchoring arrangement according to claim 1 , wherein the holding element and hollow body are adapted for interference fitment together.
3 . An arthroscopic transosseous knotless suture anchoring arrangement according to claim 1 , wherein the holding element and hollow body are adapted for removeable fitment together.
4 . An arthroscopic transosseous knotless suture anchoring arrangement according to claim 1 , wherein the hollow body further includes a rim radially extending from an end of the body.
5 . An arthroscopic transosseous knotless suture anchoring arrangement according to claim 1 , wherein the hollow varies in diameter being at least wider at one end to the other end of the body.
6 . An arthroscopic transosseous knotless suture anchoring arrangement according to claim 1 wherein the hollow tapers in diameter being at least wider at one end to the other end of the body.
7 . An arthroscopic transosseous knotless suture anchoring arrangement according to claim 1 , wherein the hollow body has an internal surface shaped to assist the fitment of the holding element therein.
8 . An arthroscopic transosseous knotless suture anchoring arrangement according to claim 1 , wherein the holding element has an outer surface shaped to assist the fitment of the holding element in the hollow body.
9 . An arthroscopic transosseous knotless suture anchoring arrangement according to claim 1 , further including comprising:
a holding element delivery device having an elongate body with an internal longitudinal aperture the length of the device having an internal diameter larger than the largest outer diameter of the holding element and the holding element delivery device further adapted, to guide the hollow body into the body and at least partially into a cortical portion of a bone.
10 . An arthroscopic transosseous knotless suture anchoring arrangement according to claim 9 , further comprising:
a holding element placement device having a length, and an outer diameter less than the smallest internal diameter of the holding element delivery device,
wherein the holding element delivery device is adapted to guide a holding element into the hollow body when the holding element placement device is inserted into the holding element delivery device after the holding element.
11 . An arthroscopic transosseous knotless suture anchoring arrangement according to claim 9 , wherein the holding element delivery device has an end shaped to conform to at least a portion of the shape of the end of the hollow body external of the cortical portion of a bone.
12 . An arthroscopic transosseous knotless suture anchoring arrangement according to claim 9 , wherein the holding element placement device includes at least one longitudinal channel on an outer surface shaped and sized to at least accommodate a suture.
13 . An arthroscopic transosseous knotless suture anchoring arrangement according to claim 12 , wherein the holding element placement device includes at least two longitudinal channels on an outer surface shaped and sized to at least accommodate a suture in each channel.
14 . An arthroscopic transosseous knotless suture anchoring arrangement according to claim 10 , wherein the holding element placement device includes a mark or indicia which indicates the length of the device that needs to he inserted into the holding element delivery device so as to ensure that the holding element is in fitment with and within the hollow body.
15 . A device for capturing and holding a suture under tension with respect to a cortical bone portion comprises:
a hollow elongate body having an inner surface forming the hollow, at least a portion of the body for placement in a cavity located in the cortical bone portion, the hollow body having a rim radially extending from, one end of the body, the rim adapted to receive a force that forces at least a portion of the rim to abut the cortical bone adjacent to the cavity in the cortical bone; and
a holding element sized for fitment with and within the hollow of the body;
wherein a portion of the suture is located within the hollow body and while, the free end of the suture is under tension caused by a force on the suture applied in a direction away from the outer surface of the cortical bone, and another force in substantially the opposite direction is applied to the rim of the body, the holding element is interference fitted into the hollow body so as to capture a portion of the suture under tension which is located within the hollow body while the rim of the body abuts the cortical bone portion and also holds the captured portion of the suture with respect to the cortical bone portion.
