A method of tissue repair using expandable surgical anchors and knotless fixation. The method includes coupling repair strands to tissue to be fixed and inserting an implant with the repair strands captured by the implant into a pre-drilled bone hole in an insertion direction. After the implant is inserted into the bone hole, an expandable cannulated fixation device is placed within the bone hole such that the repair strands are disposed outside the fixation device. After the fixation device is placed within the bone hole, the fixation device is expanded by pulling the implant into the fixation device in an actuation direction while the fixation device remains stationary, thereby compressing the fixation device against the bone hole with the repair strands disposed between the outer surface of the fixation device and the bone hole, and fixating the tissue without creating knots.

Surgical anchoring systems for use with a surgical instrument for endoluminal access are provided. The surgical instrument includes an outer sleeve defining a working channel therethrough. The outer sleeve is configured to be disposed within a first natural body lumen. A channel arm is configured to extend through the working channel and to move independently relative to each other. The channel arm has an anchor member and is configured to move between expanded and unexpanded states. When in the expanded state, the anchor member is configured to be disposed within a second natural body lumen. A control actuator extends along the channel arm and is operatively coupled to the anchor member, the control actuator being operatively coupled to a drive system that is configured to control motion of the channel arm to selectively manipulate an organ associated with the first and second natural body lumens.

Surgical anchor structures, fixation devices, and methods of manufacture, as well as methods for tissue repair are disclosed. A soft suture anchor has a sheath having a varying density along a length of the sheath. The anchor sheath may include different segments having different densities, which may be provided in a pattern or random manner. The segments of different densities allow the soft anchor to be securely secured within the bone and attach the first tissue to the second tissue.

A surgical anchoring device may include a first beam and a second beam each extending along a longitudinal direction; and a connecting member bridging a first proximal portion of the first beam to a second proximal portion of the second beam such that the first beam is substantially aligned with the second beam. In addition, the anchoring device may include a first barb protruding from a medial side of the first beam, wherein the first barb extends diagonally in a generally proximal direction; and a second barb protruding from a medial side of the second beam, wherein the second barb extends diagonally in a generally proximal direction.
