Percutaneous Tether Locking

An implant is provided that includes first and second tissue anchors, which include (a) first and second tissue-coupling elements, respectively, and (b) first and second heads, respectively, which include first and second tether interfaces; and one or more tethers, which are connected to the first tether interface, and coupled to the second tether interface. The first and second tissue anchors are removably positioned in a catheter shaft of a multiple-anchor delivery tool at first and second longitudinal locations, respectively, the first longitudinal location more distal than the second longitudinal location. First and second torque cables of the delivery tool (a) are removably coupled to the first and second heads, respectively, (b) extend within the catheter shaft proximally from the first and second heads, respectively, and (c) transmit torque when rotated. A portion of the first torque cable is removably positioned alongside the second tissue anchor in the catheter shaft.

Devices, systems and methods for retracting, lifting, compressing, supporting or repositioning tissues or anatomical structures

Devices, systems and methods for retracting, lifting, compressing, supporting or repositioning tissues, organs, anatomical structures, grafts or other structures within the body of human or animal subjects for the purpose of treating a diseases or disorders and/or for cosmetic or reconstructive purposes and/or for research and development purposes or other purposes.

SUTURE METHODS AND DEVICES

A barbed suture including a body with barbs on the periphery, a pointed end, and an anchor at one end to resist movement of the suture in the direction of the pointed end is provided. One or more limbs on the anchor may be provided, which may be arcuate, of varying lengths, and of varying distribution about the periphery of the suture body. Other anchor designs are provided. Methods of placing single-directional and bi-directional barbed sutures to approximate the tissue on each side of a wound and to position and support tissue in the absence of a wound, as in cosmetic surgery, are provided, and may include terminal J-stitches or S-stitches. Methods of placement may be made with sharp, pointed ends, which may be needles, or insertion devices. Sinusoidal patterns of sutures that have amplitudes generally perpendicular to the resultant holding force of the suture are provided.

Devices, systems and methods for treating benign prostatic hyperplasia and other conditions

Devices, systems and methods for compressing, cutting, incising, reconfiguring, remodeling, attaching, repositioning, supporting, dislocating or altering the composition of tissues or anatomical structures to alter their positional or force relationship to other tissues or anatomical structures. In some applications, the invention may be used to used to improve patency or fluid flow through a body lumen or cavity (e.g., to limit constriction of the urethra by an enlarged prostate gland).

FLEXIBLE ANCHOR DELIVERY SYSTEM

An assembly includes a flexible fixation member, a suture, and a delivery device. The fixation member includes a body with two terminal ends. A suture passes through the flexible fixation member at various points along a length of the body such that portions of the fixation member are slidable relative to the suture and configurable to form a cluster within a surgical site. The delivery device includes a tubular member, an elongated inserter, and a trigger. The elongated inserter is slidably disposed within the tubular member. The inserter has a forked distal end configured to receive a portion of the fixation member and the suture. The trigger is finger-engagable and fixedly coupled to the proximal end of the inserter. It is configured to advance and retract the inserter relative to the tubular member. The trigger includes a retention member for retaining a proximal end portion of the suture.

Suture anchor construct

Disclosure herein are knotless suture anchor constructs and methods of use thereof. The suture anchor constructs can include a bone anchor and a suture. The bone anchor can include a suture anchoring member and can define a cavity and a longitudinal passage extending from a trailing end of the bone anchor at least partially therethrough to the cavity. The suture anchoring member can be located in the cavity. The suture can be coupled to the suture anchoring member and can include a tensioning portion, a repair portion, and an intermediate portion. The intermediate portion can form a suture loop extending along the longitudinal passage.

SUTURE ANCHOR DRIVER

A suture anchor driver with a tensioning mechanism. The suture anchor driver has a handle with a proximal end and a distal end. The handle has a recess with a shaft extending centrally therefrom. The suture anchor driver has a detent ring and a spool. The detent ring has a central aperture and one or more projections. The spool has a central aperture and is rotatable between first and second configurations. The spool has a plurality of protrusions extending from its side. The shaft extends through the central apertures in the detent ring and spool such that the projections of the detent ring are adjacent the protrusions extending from the spool. In the first configuration, one of the projections extends between two of the protrusions. In the second configuration, one of the projections is aligned with one of the protrusions.

Post-Implantation Tension Adjustment in Cardiac Implants
20180249993 · 2018-09-06 · ·

A method of treating a heart of a patient is provided, including implanting a first tissue anchor in cardiac tissue of the patient, the first tissue anchor attached to one or more tethers that are fixed to a coupling element. A second tissue anchor is implanted in the patient. The coupling element is coupled to a first coupling site of the second tissue anchor, thereby coupling the first tissue anchor to the second tissue anchor via the one or more tethers. Thereafter, after allowing at least 24 hours for tissue growth on the first tissue anchor to strengthen anchoring of the first tissue anchor in the cardiac tissue, tension is increased between the first and the second tissue anchors by decoupling the coupling element from the first coupling site and coupling the coupling element to a second coupling site of the second tissue anchor. Other embodiments are also described.

Adjustable loop constructs and techniques
10064716 · 2018-09-04 · ·

A device for securing tissue or bone. The device includes a self-locking construct, which includes first and second adjustable loops. The first adjustable loop includes a loop passage portion through which a first portion of the self-locking construct extends. The second adjustable loop extends through a sleeve defined by the self-locking construct. The self-locking construct is configured such that moving the second adjustable loop away from the first loop closes the first adjustable loop, and pulling the first portion further through the loop passage portion closes the second adjustable loop.
