Bone anchor installer and method of use
First Claim
Patent Images
1. A bone anchor installer system comprising:
- a handle portion;
a loading portion comprising a proximal end coupled to the handle portion and a distal end adapted to releasably couple to a bone anchor;
an anchor holder removably coupled to the distal end of the loading portion, the anchor holder comprising at least two portions, the at least two portions comprising a first portion releasably coupled to a second portion, and a cavity sized to accept the distal end of the loading portion and a bone anchor coupled thereto; and
a mechanism adapted to uncouple the first and second portions of the anchor holder from the loading portion while the distal end of the loading portion and the bone anchor are within the cavity.

Abstract
Systems, apparatuses and methods for securing tissue to bone using a bone anchoring system are described. Methods and apparatuses may allow transformation between locked and unlocked states, thereby allowing adjustment of the tension in the suture. The apparatus and/or methods may allow unidirectional movement of a suture, while preventing slippage or movement of the suture and tissue in the opposite direction. Ends of a suture may be individually tensioned to adjust positioning of a tissue with respect to a bone.

14. A bone anchor installer system comprising:
-
a handle portion; a loading portion coupled to the handle portion, the loading portion having a distal end adapted to releasably couple to a bone anchor; an anchor holder removably coupled to the distal end of the loading portion, the anchor holder comprising; a longitudinal axis; a cavity extending substantially along the longitudinal axis, the cavity sized to accept the distal end of the loading portion and the bone anchor coupled thereto; a first portion defining a first inner surface of the cavity; and a second portion releasably coupled to the first portion, the second portion defining a second inner surface of the cavity, wherein the first inner surface is on one side of the bone anchor and the second inner surface is on another side of the bone anchor with respect to the longitudinal axis when the bone anchor is accepted in the cavity; and a mechanism adapted to uncouple the first portion and second portions of the anchor holder from the loading portion. - View Dependent Claims (17, 18, 21)

15. A bone anchor installer system comprising:
-
a handle portion; a loading portion coupled to the handle portion, the loading portion having a distal end adapted to releasably couple to a bone anchor; and an anchor holder removably coupled to the distal end of the loading portion, the anchor holder comprising; a longitudinal axis; a cavity sized to accept the distal end of the loading portion and the bone anchor coupled thereto; a first portion; and a second portion releasably coupled to the first portion, wherein the first portion and second portion surround the distal end of the loading portion and the bone anchor in a coupled configuration of the anchor holder, and wherein the first portion and the second portion are removable from the distal end of the loading portion and the bone anchor along an orthogonal direction with respect to the longitudinal axis in a released configuration of the anchor holder. - View Dependent Claims (19, 20, 22)

23. A bone anchor installer system, comprising:
-
a handle portion; a loading portion comprising a proximal end coupled to the handle portion and a distal end releasably coupled to a bone anchor; an anchor holder removably coupled to the distal end of the loading portion, the anchor holder comprising; at least two portions, the at least two portions comprising a first portion releasably coupled to a second portion, and a cavity sized to accept the distal end of the loading portion and the bone anchor coupled thereto; a mechanism adapted to uncouple the first and second portions of the anchor holder from the loading portion while the distal end of the loading portion and the bone anchor are within the cavity; a suture puller engaged with the anchor holder and the bone anchor located in the cavity, the suture puller comprising; a first end configured to couple with one or more sutures; and a second end configured to allow an operator to pull the suture puller through the anchor holder and the bone anchor, to couple the suture to the bone anchor prior to uncoupling of the first and second portions. - View Dependent Claims (24, 25, 26, 27, 28, 29)
