Fully threaded suture anchor with internal, recessed eyelets

摘要

A suture anchor according to embodiments of the invention includes a body (102) having a proximal (121) and distal (125) ends and at least two suture paths open towards the proximal end and not open (e.g. looped around) towards the distal end and which are respectively capable of receiving a suture, and a proximal cavity (103) opening into a transverse cavity (104). The anchor may also include a transverse wall (105) arranged at least partially in the transverse cavity (104), and for each suture path, a distinct eyelet (112) for the passage of a suture through the transverse wall (105), so that a suture thread (162) in place in the anchor (100) forms a U with a first strand (162a) along the longitudinal axis (X-X), a second strand (162c) substantially parallel thereto, and an arc (162b) formed in the eyelet (112) and connecting the first and second strands.

主权项

1. A suture anchor comprising:
a body, wherein the body is elongated, extends along a longitudinal axis, and comprises a proximal end and a distal end; a proximal cavity formed in the body, the proximal cavity extending from the proximal end into the body; a transverse cavity formed in the body at least partially transversely to the longitudinal axis, between a first side of the body and a second side of the body opposite the first side, wherein the proximal cavity opens into the transverse cavity; a transverse wall at least partially spanning the transverse cavity, the transverse wall having a first face oriented toward the first side and a second face oriented toward the second side; a first eyelet extending through the transverse wall between the first face and the second face; and a second eyelet extending through the transverse wall between the first face and the second face, wherein the first and second eyelets are arranged such that a first suture may be inserted through the proximal cavity, over the first face, through the first eyelet, over the second face, and back through the proximal cavity, and a second suture may be inserted through the proximal cavity, over the first face, through the second eyelet, over the second face, and back through the proximal cavity; wherein the first and second eyelets are intersected by an axis that is perpendicular to the longitudinal axis of the body; a third eyelet extending through the transverse wall between the first face and the second face, wherein the first, second, and third eyelets are further arranged such that a third suture may be inserted through the proximal cavity, over the first face, through the third eyelet, over the second face, and back through the proximal cavity wherein the first and second eyelets each extend through the transverse wall at a first position along the longitudinal axis, and wherein the third eyelet extends through the transverse wall at a second position along the longitudinal axis; wherein the first and second eyelets are located between the proximal end and the third eyelet.
