Abstract
An adjustable construct for fixation of a tendon or ligament graft in a tunnel. The construct comprises a flexible, adjustable loop connected to tissue (for example, graft, ligament or tendon). The adjustable loop may be integrated with an additional tissue supporting device (for example, a wedge or a plug). The tissue is secured within a bone socket/tunnel by adjusting the length of the flexible adjustable loop.
Core Innovation
The invention provides an ACL construct that includes a fixation device, a graft supporting device configured to support a graft, and an adjustable loop attached to both the fixation device and the graft supporting device. The graft supporting device is comprised of a plug, a wedge, or an anchor, and includes structural features configured to interface with portions of the adjustable loop and with a driver.
The adjustable loop includes a free braid strand that is spliced through a portion of the adjustable loop and is tensionable to reduce a size of the adjustable loop. The arrangement supports one-direction tensioning behavior while resisting loosening in the opposite direction via the spliced adjustable eyesplices and free braid strands, where the loop length can be changed after attachment.
The graft supporting device includes a passageway configured to receive a first portion of the adjustable loop and an opening configured to receive a driver. In implementations, the graft rests over a saddle of the graft supporting device, where the saddle includes a concave surface formed in a proximal end portion and a cylindrical plug is located at a distal end portion opposite the saddle.
Claims Coverage
The provided material identifies three independent ACL construct claims. Across these independent claims, the inventive aspects focus on an adjustable loop with a spliced free braid strand and tensionable size reduction, a graft supporting device with passageway and opening features to receive loop portions and a driver, and a graft-support geometry combining a saddle with a concave proximal surface and a cylindrical distal plug.
Adjustable-loop ACL construct with spliced free braid strand and driver-accessible graft supporting device
An ACL construct comprising a fixation device; a graft supporting device configured to support a graft and comprised of a plug, a wedge, or an anchor; and an adjustable loop attached to both the fixation device and the graft supporting device, wherein the adjustable loop includes a free braid strand that is spliced through a portion of the adjustable loop and is tensionable to reduce a size of the adjustable loop, wherein the graft supporting device includes a first passageway configured to receive a first portion of the adjustable loop, and wherein the graft supporting device includes an opening configured to receive a driver.
Saddle-received graft with concave proximal surface and cylindrical distal plug in adjustable-loop ACL construct
An ACL construct comprising a fixation device; a graft supporting device; an adjustable loop attached to both the fixation device and the graft supporting device; and a graft resting over the graft supporting device such that the graft is received within a saddle of the graft supporting device, wherein the saddle includes a concave surface formed in a proximal end portion of the graft supporting device, and wherein the graft supporting device includes a cylindrical plug at a distal end portion of the graft supporting device that is opposite from the saddle.
Saddle-received graft with concave proximal surface, cylindrical distal plug, and proximal passageway for adjustable loop
An ACL construct comprising a fixation device; a graft supporting device; an adjustable loop attached to both the fixation device and the graft supporting device; and a graft resting over the graft supporting device such that the graft is received within a saddle of the graft supporting device, wherein the saddle includes a concave surface formed in a proximal end portion of the graft supporting device, wherein the graft supporting device includes a cylindrical plug at a distal end portion of the graft supporting device that is opposite from the saddle, and wherein the proximal end portion of the graft supporting device includes a first passageway configured to receive a portion of the adjustable loop.
Collectively, the independent claims cover ACL constructs that connect a fixation device to a graft supporting device via an adjustable loop, including a spliced, tensionable free braid strand and graft supporting device passage and opening features for receiving loop portions and a driver. Additional independent claim coverage emphasizes a graft-on-saddle configuration with a concave proximal surface and a cylindrical distal plug, including a proximal passageway configured to receive a portion of the adjustable loop.
