The present disclosure provides embodiments of a method for improving coaptation of the anterior and posterior mitral valve leaflets by applying a remodeling force to the posterior leaflet. In particular embodiments, a tension member is secured at a location on or proximate to the posterior leaflet. Tension can be applied to the tension member in a direction superiorly and anteriorly toward the interatrial septum. The tension member can be secured at a location proximate the septum to maintain the tension. The tension provides the remodeling force, pulling the posterior leaflet superiorly and anteriorly to improve coaptation with the anterior leaflet.

A suture construction and method for forming a suture construction is disclosed. The construction utilizes a suture having an enlarged central body portion defining a longitudinal passage. First and second ends of the suture are passed through first and second apertures associated with the longitudinal passage to form a pair of loops. Portions of the suture lay parallel to each other within the suture. Application of tension onto the suture construction causes constriction of the longitudinal passage, thus preventing relative motions of the captured portions of the suture.

Systems and methods are provided and adapted to engage and pull (e.g., pull up) or reposition urethral support tissue, such as the portion of the perineal membrane above or below the urethra. The perineal membrane intersects the urethra and vagina at the midurethra or distal location and can thus be stabilized or controlled in a manner that helps restore continence.

Medical devices for applying a cinch to a suture and methods for making and using such devices are disclosed. An example medical device may include an elongated shaft including a proximal region and a distal region. The distal region may define a lumen having a lumen dimeter, and a distally facing end surface. The medical device may also include an outer cinch member defining a bore and having an outer surface defining a shoulder. An elongated inner shaft may extend through and be longitudinally movable within the lumen and the bore and including a distal end section. An inner cinch member may be engaged with the distal end section of the elongated inner shaft.

Knots and methods of forming knots made of flexible material for use in a surgical environment are described. The knots include one or more ways to unlock at least a portion of the knot.

A surgical suturing and knotting integrated device includes a knotting assembly and an operation/control apparatus. The knotting assembly has a suture pre-tied with a slipknot and a loop. In use, the knotting assembly is mounted on a front end of the operation/control apparatus and the front end of the operation/control apparatus is extended into a patient's abdominal cavity to perform laparoscopic surgery. In suturing process, the operation/control apparatus is used to enlarge the loop of the suture, whereby the suture and one end of the suturing needle can be easily passed through the loop. Then, the operation/control apparatus is used to minify the loop and detach the slipknot of the suture from the knotting assembly and change the slipknot into a fixed knot.

A method of implanting a prosthetic mitral heart valve includes advancing a guidewire through a femoral vein, an atrial septum, and a native mitral valve. A guide catheter is advanced over the guidewire and a delivery catheter is advanced through the guide catheter. A mitral valve assembly is disposed along a distal end of the delivery catheter. The mitral valve assembly includes a stent and a valve having three leaflets. The stent has a flared inlet end, an outlet end, and an intermediate portion with a plurality of prongs disposed along its outer surface. The mitral valve assembly is deployed with the flared inlet end positioned in a left atrium and the intermediate portion positioned between native mitral valve leaflets. The prongs penetrate surrounding tissue for preventing upward migration of the mitral valve assembly and the flared inlet end is shaped for preventing downward migration.

A surgical instrument, such as a capsular retractor, and methods of use are disclosed.

Devices for closing a passage through tissue communicating with a body lumen. The device may include an elongate body, a sheath disposed at the distal end of the device for disposition within a body lumen, a hollow needle disposed within a needle lumen of the body, the needle being selectively advanceable through the needle lumen, a suture-anchor ejection mandrel disposed within the hollow needle that is also selectively advanceable through the hollow needle, a suture-anchor and suture disposed within the hollow needle, a distal end of the suture attached to the suture anchor for ejection out the hollow needle by the mandrel. A needle guide disposed between the sheath and proximal end of the body may include a needle port through which the needle can exit. A hemostatic plug is disposed over the needle port so as to be penetrated by the needle upon exiting the port.

A suture anchor for fixation within an anatomical structure includes an actuation member in contact with an anchor body at a first location thereof. The anchor body is elongate along a direction of elongation and defines a central axis. In a neutral configuration, the anchor body is flat and defines a thickness along a transverse direction and a width along a lateral direction, the width being greater than the thickness. The anchor body has first and second tails that are braided together along a portion of the actuation member from the first location to a second location of the anchor body. The actuation member is configured to apply a force to the braided anchor body so as to actuate the anchor body in a manner increasing its maximum thickness along a second direction that is angularly offset from the direction of elongation.
