Systems and methods are provided for performing tensionable knotless surgical procedures. A suture locking device that includes a one-way locking mechanism may be utilized for tensioning and locking one or more strands of suture during the surgical procedure. The one-way locking mechanism may be established by one or more locking barbs of the suture locking device.

A surgical retractor is provided with a plurality of gears, and first and second legs, each having a proximal end and a distal end. The first and second legs are constructed and arranged for the removable attachment of retractor blades thereto. An adjustment component is configured to be rotated in different directions. A plurality of gears provides a continuous rotational motion to the first and second legs when the adjustment component is rotated. The first and second legs move between the closed position and an unlimited number of open positions such that edges of a tissue of a body in contact with the retractor blades separate or are loosened from a recent separation. The retractor's low radiodensity will provide improved visibility of the surgical site and obviate the need to remove it from the surgical site for x-ray throughout the procedure.

A guidewire capturing device may include a handle that may have a central aperture extending in an axial direction therethrough. The device may also include a wire housing having a wire aperture extending in the axial direction therethrough, the wire aperture may have a guidewire positioned therewithin. The wire housing may be at least partially contained within the central aperture and selectively movable in the axial direction within the central aperture from a first position to a second position. The device may include a clutch, which may be connected to the handle and selectively movable between an engaged position and a disengaged position, the engaged position corresponding to a threaded engagement between the wire housing and the clutch, and the disengaged position corresponding to free axial movement of the wire housing within the central aperture between the first position and the second position.

Present invention provides a steerable articulating surgical instrument comprising an external hollow shaft, wherein the external hollow shaft comprises a bendable portion and a steering arrangement adapted to apply a bending force to the bendable portion, wherein the bendable portion comprises a resilient bendable member adapted to resist the bending force.

A surgical tool includes a drive housing, a shaft extending from the drive housing, wrist arranged at an end of the shaft and including a distal clevis, an axle mounted to the distal clevis, and first and second actuation pulleys rotatably mounted to the axle and rotatable about a pivot axis extending through the axle, each actuation pulley providing an actuation boss eccentric to the pivot axis, and an end effector operatively coupled to the wrist and including first and second blades pivotably coupled to the actuation bosses of the actuation pulleys. The blades are movable between open and closed positions by rotating the actuation pulleys such that the actuation boss of each actuation pulley remains proximal to a centerline of the axle, and movable to an over-centered position by rotating the actuation pulleys such that the actuation boss of each actuation pulley is located distal to the centerline.

A surgical tool includes a drive housing, an elongate shaft extending distally from the drive housing, a wrist arranged at a distal end of the shaft and including a distal clevis with first and second distally-extending arms, and an end effector operatively coupled to the wrist. The end effector including a first blade holder rotatably mounted to the first arm at a first axle, a second blade holder rotatably mounted to the second arm at a second axle, a first blade releasably coupled to the first blade holder with a first securing device, and a second blade rotatably coupled to the first blade at a center pin and releasably coupled to the second blade holder with a second securing device. Disengaging the first and second securing devices from the first and second blade holders allows the first and second blades to be separated from the first and second blade holders.

An exemplary catheter for use in a body lumen comprises: a catheter body; and a plurality of shock wave emitters disposed at a distal end of the catheter body, each shock wave emitter configured to generate a shock wave that propagates distally of the catheter body, wherein the plurality of shock wave emitters are arrayed about a longitudinal axis of the catheter body such that shock waves emitted from the plurality of shock wave emitters can constructively interfere distally of the catheter body, and wherein each shock wave emitter comprises electrodes separated by a spark gap and at least one electrical connector that connects at least one of the electrodes to an electrode of another shock wave emitter of the plurality of shock wave emitters.
