A medical device may include an insertion device having a proximal end, a distal end, and a lumen extending therethrough. The medical device may further include a snare device configured to transition between a contracted state within the lumen of the insertion device, and an expanded state extending distally of the insertion device. The snare device may include a loop including a pair of legs and a distal tip. The distal tip may include a plurality of stabilizers between the pair of legs.

A system for harvesting a tendon graft is disclosed, including a retractor, a guide and a harvesting tool. The retractor is collapsible and upon release, becomes self-supporting to hold open an anatomic space developed in a patient above the tendon. A guide assembles with the retractor to orient a guide shaft along the retractor and thereby the anatomic space. The harvesting tool includes a working end with a blade edge for cutting into the tendon. The harvesting tool defines a contoured surface for engaging and translating along the guide shaft while assembled to the retractor. The guide shaft and contoured surface limit the trajectory and translation extent of the harvesting tool along and into the tendon.

A device is described. The device includes a suture guide and a tissue retracting surface to enable accurate and safe delivery of sutures through tissue.

A system and related methods of preventing wrong-site surgeries and blade-related injuries to OR personnel, which includes a computer software system (for use on computers or hand-held devices in the medical environment) in combination with a surgical supply carrier (such as a safety blade-dispenser or other surgical sharps dispenser). The surgical supply carrier comprises at least one component, such as a label, which prevents or impedes a surgeon from accessing one or more surgical instruments stored within until after a “time-out” is performed by the surgeon or authorized OR personnel to confirm various details including but not limited to correct patient, correct procedure, correct equipment, etc, before starting the intended surgical procedure. Data can be captured throughout the medical environment (from “decision-to-incision” and beyond) to assess wrong-site surgery data (including “near miss” data) and enable a host of analytics on wrong-site surgery prevention.

An electrosurgical forceps includes first and second shafts configured to rotate about a pivot to move jaw members between an open position and a closed position. A knife deployment mechanism is operably coupled to a knife and is configured to move the knife between a retracted position and an extended position. A knife lockout is configured to move between a first position wherein the jaw members are in the open position and movement of the knife from the retracted position to the extended position is prevented, a second position wherein the jaw members are in the closed position and movement of the knife from the retracted position to the extended position is permitted, and a third position wherein the jaw members are in the closed position and movement of the knife from the retracted position to the extended position is prevented.

A smoke evacuator for use with a surgical access device includes an evacuation ring having an inner peripheral surface defining one or more channels therein disposed in fluid communication with an operating cavity. A connection port is disposed thereon in fluid communication with the channel(s) and adapted to connect to a smoke evacuation system. The evacuation ring includes a profile having an inner flange that forms part of the inner peripheral surface of the evacuation ring and one or more lower flanges, the inner flange is configured to mechanically engage a rim of an access device and the lower flange(s) is adapted to mechanically engage a wound guard, wherein engagement of the inner flange of the evacuation ring atop the access device and engagement of the lower flange(s) with the wound guard secures the access device, the wound guard and the smoke evacuation ring within the operating cavity.

Devices for removing implanted objects from body vessels are provided. A device includes a sheath assembly having a cutting tip. The cutting tip includes a cutting surface that is adapted to cut tissue coupled to an implanted object as the cutting tip rotates. The sheath assembly further includes an outer shield carried outside of the cutting tip. The outer shield includes a distal opening, and the outer shield is translatable relative to the cutting tip from a first position to a second position and vice versa. In the first position the cutting surface of the cutting tip is disposed within the outer shield, and in the second position the cutting tip extends through the distal opening and the cutting surface is at least partially disposed outside of the outer shield.

A tool for installing and/or removing a protective cover of an instrument includes a body portion having an open end and a closed end. The open end defines an interior passage that extends into the body portion along a longitudinal axis of the body portion toward the closed end of the body portion. The interior passage is configured to receive at least a portion of the protective cover in the interior passage. One or more members are connected to the body portion, and each of the one or more members includes a free end movable relative to the body portion. Systems and methods relate to tools for installing and/or removing protective covers of instruments.

Removable catheter cap, and applications thereof, for delivering medical tubes in bodily passages. Removable catheter cap covers flexible medical tube (e.g., catheter) distal tip during delivery in a body lumen. Catheter cap includes: cap body removably connectable to, for capping, catheter distal tip, and transformable into a predefined constituent part freely passable through catheter lumen; and cap releasing member extending through catheter proximal end when catheter cap is connected to the catheter, and manipulatable for transforming cap body into constituent part or/and for withdrawing constituent part from catheter distal tip through catheter lumen. Exemplary applications are: provision of a catheter assembly including a catheter and the removable catheter cap connected thereto; a medical kit including one or more catheters and one or more correspondingly configured removable catheter caps; and a method for delivering a catheter in a blood vessel of a subject, for example, via an over-the-wire technique.

A drill bit (20, 420, 520, 620, 720, 820, 920, 1020) is provided that includes a connector (32, 232, 532, 632, 732, 832, 932, 1032), which includes a shank (34), configured to receive torque; a proximal electrically-conductive coupler (36, 436, 536, 636, 736, 836, 936, 1036), which is disposed at a distal end (28) of the shank (34), rotationally fixed with respect to the shank (34); and a distal electrically-conductive coupler (38, 238, 438, 538, 838, 738, 838, 938, 1038). The distal electrically-conductive coupler is rotationally fixed with respect to the proximal electrically-conductive coupler, electrically isolated from the proximal electrically-conductive coupler, and shaped so as to define a distal-electrically-conductive external contact surface (62, 862, 962, 1062). The drill bit further includes a drill shaft (30, 130, 230, 330, 430, 830) including an electrically-conductive outer electrode (44) and an electrically-conductive inner electrode (46, 146, 246, 346, 846). Other embodiments are also described.
