Disclosed are improved methods, apparatus and/or systems for securing and/or anchoring tissue structures to bones, including unicortical soft tissue fixation.

Disclosed are devices, methods and/or systems for securing tissue to bone, including a suture anchor implant having a body with an internal cavity and one or more helical cutting flutes positioned on an external surface of the body which direct at least a portion of the cut bony material into the internal cavity as the body is rotated into bone.

An implant for attaching a tendon or ligament to a hard tissue is provided. The implant includes a head, a first prong, a second prong, first pillars for contacting a hard tissue, first slots to be occupied by the hard tissue, second pillars for contacting a tendon or ligament, and second slots to be occupied by the tendon or ligament. The implant has a Youngs modulus of elasticity of at least 3 GPa, a first surface ratio of the sum of the volumes of the first slots to the sum of the volumes of the first pillars and the first slots of 0.40:1 to 0.90:1, and a second surface ratio of the sum of the volumes of the second slots to the sum of the volumes of the second pillars and the second slots of 0.60:1 to 0.98:1. The second surface ratio is greater than the first surface ratio.

A variety of configurations of implant management devices are provided. The configurations provide different combinations of features for maintaining a location of an implant with respect to the device and managing filaments of the implant. One exemplary embodiment of a device includes a generally rectangular-shaped body having an implantable body retainer, an opening disposed a distance apart from the retainer and configured to receive a ligament graft therein, and a fold extending across the body and intersecting the opening. Folding one end of the body towards a bottom surface of the body along the fold can form a filament loop engaging region to hold in tension a filament loop extending from the implant. Additional filament(s) associated with the implant can be managed by various filament retention features. Methods for preparing a ligament graft for implantation by relying upon indicia formed on a surface of the device body are also provided.

A toggle-type suture anchor that incorporates individual suture tensioning and locking without knot tying. The anchor includes several exemplary designs of toggle bodies having a working suture pre-threaded through one or more passages therethrough. A locking suture loop is pre-threaded relative to the working suture and includes a collapsible loop that encircles a portion of the length of suture running longitudinally adjacent the side of the anchor. With the loop open, the working suture can slide through the anchor, however, when the loop is closed the working suture is locked in position to retain tension on the working suture. Alternatively, the locking suture loop can be replaced with a mechanical locking member that moves from a first unlocked to a second locked position. The exemplary anchors can be utilized in a pre-strung connected array of anchors.

Devices, systems, implants and methods for achieving ligament fixation are disclosed. An implant includes a head member and an anchor member coupled to the head member. The implant includes tension member that couples the head member to the anchor member. The head member and the anchor member include a cannulation that receives the tension member therein. The implant may include a coupling member positioned between and coupling the head member and the anchor member, the coupling member including a cannulation that receives the tension member therethrough. Insertion instruments for inserting an implant for ligament fixation are also disclosed. Methods of using an implant for achieving ligament fixation are also disclosed.

A suture assembly, including a button having two apertures and a suture defining a lumen and forming a double loop, formed by a double trap having a first end and a second end, opposed to the button. A first portion of the suture is threaded through the trap from the first end to the second end, and a second portion of the suture is threaded through the trap from the second end to the first end. The assembly further defines a first single trap, in which the first portion of the suture is threaded through the lumen between the second end and the button. Also defined by the assembly is a third trap, in which the second portion of the suture is threaded through the lumen between the first end and the button. Finally, the double loop is threaded through the two apertures of the button.

A filter device for implantation in a gallbladder, comprising: a filter portion configured to filter gallstones of a certain minimum size to prevent them from exiting the gallbladder through an opening of the gallbladder; a blocking portion configured to push gallstones of a certain minimum size away from an opening of the gallbladder where the blocking portion is located distally from the filter portion with respect to the opening of the gallbladder; and, where the blocking portion and the filter portion do not attach to, or apply expansive radial force on, a wall of the gallbladder.

Systems and methods for fixating a graft in a bone tunnel are provided. In general, the system includes a tissue fixation device having a delivery configuration and a deployed configuration, at least one graft retention loop coupled to the tissue fixation device, and a drill pin having a sidewall surrounding a cavity at a proximal end of the pin and at least one longitudinally oriented opening in the sidewall in communication with the cavity, the cavity being configured to fully seat the tissue fixation device. The drill pin is configured to substantially contain therein the tissue fixation device when in the delivery configuration and to enable deployment of the tissue fixation device through the opening. Drill pins configured to contain a tissue fixation device are also provided.

An improved modular rotational device includes a first and second threaded coupler for affixation along the stem of an endoprosthetic device, for example, a humeral prosthesis or a femoral prosthesis. The rotational device axis of rotation is coaxial with the stem, and its axis of rotation is located in close proximity to the intramedullary stem of the prosthesis or in close proximity to the distal articulation of the prosthesis. A housing has a proximal and distal end with an axial bore therethrough for receiving an elongated stem of the device. A lobe ring may be utilized to limit the axis of rotation of the device. Additional endoprosthetic devices may be attached to male or female threaded couplers, or to Morse tapers. A plurality of suture attachments facilitates attachment of soft tissue thereto.
