Abstract: A medical delivery system including a carrier and a lead delivery device. The carrier defines a carrier body configured to engage a stereotactic system (or a similar pointing device with or without navigation/robotic assistance). The carrier defines a carrier channel configured to engage the lead delivery device and impart a torque to a portion of the lead delivery device. The lead delivery device and carrier are configured to cause the imparted torque to cause a cannula of the lead delivery device to rotate about a longitudinal axis of the lead delivery device. The cannula is configured to cause a rotation of an implantable lead within the cannula when the cannula is caused to rotate. The cannula is configured to translate substantially parallel to the longitudinal axis relative to the implantable lead.

Abstract: Microinvasive medical scissors include a first scissor blade (30) with a first cutting edge (35, 36) between a flank surface (33) and a beveled surface (37, 38), a relatively moveable second scissor blade (40) with a second cutting edge (45, 46) between a flank surface (43) and a beveled surface (47, 48), a guiding device (24) for mechanical guiding of the second cutting edge to touch the first cutting edge at any time in a point of intersection (50). The guiding device is connectable to a shaft (16) of a microinvasive instrument (10). The cutting edges have respective parameters which increase and decrease several times along the second cutting edge. The parameters are the wedge angle (?1, ?2,) between the flank surface and the beveled surface, the cutting angle (?1, ?2), or the width (b1, b2) of the beveled surface.

Abstract: Various exemplary systems and devices for knotless anchor insertion and methods of knotless anchor insertion are provided. In general, an inserter tool is configured for knotless anchor insertion in a soft tissue repair surgical procedure. The inserter tool is configured to insert an anchor into a bone of a patient to secure a soft tissue relative to the bone. A suture coupled to the soft tissue is secured relative to the bone by being trapped between an exterior surface of the anchor and a bone surface defining a hole in the bone in which the anchor is positioned.

Abstract: A robotic surgical tool includes an elongate shaft, an end effector arranged at a distal end of the shaft and including opposing first and second jaws, and an articulable wrist that interposes the end effector and the distal end, the wrist including a linkage providing one or more lateral arms receivable within a corresponding one or more grooves defined in the first and second jaws, wherein mounting the linkage to the first and second jaws at the corresponding one or more groove generates a jaw pivot where the first and second jaws pivot between open and closed positions.

Abstract: The invention discloses a plague removal device, comprising, a push catheter, a plaque scraping stent, a support tube, an elastic filter membrane, a guide catheter, and a handle, wherein the plaque scraping stent is a mesh structure sleeved outside the support tube, a distal end of the plaque scraping stent is fixed on a distal end of the support tube, a proximal end of the plaque scraping stent is fixed on a distal end of the push catheter, the support tube is sleeved inside the push catheter; a distance between the distal end of the push catheter and the distal end of the support tube is adjusted by the handle, so that an outer diameter of the plaque scraping stent is varied. The unique structure design of “tapered structure” in the present invention can ensure good compliance during the entry and withdrawal of the stent.

Abstract: The disclosure relates to a surgical device configured to both strip and cut a tendon. The harvested tendon can be used in various orthopedic procedures, such as ACL, PCL, and UCL reconstructions.

Abstract: An automatic tourniquet apparatus comprises a tourniquet cuff, a pressure transducer, a user interface, a patient hazard shield and a pressure regulator. The pressure transducer produces a cuff pressure signal. The user interface produces a reference pressure signal. The patient hazard shield is responsive to the cuff pressure signal and the reference pressure signal, and operable during a regulation time period to produce a patient hazard signal if, in one implementation, a current level of pressure in the tourniquet cuff is greater than the reference level of pressure by at least a predetermined overpressure limit. The pressure regulator is responsive to the patient hazard signal, and has a pressurizing element for increasing pressure in the cuff and a depressurizing element for decreasing pressure in the cuff. The pressurizing element is configured to be non-responsive if the patient hazard signal is produced.

Abstract: A surgical instrument includes an end effector having a first jaw member and a second jaw member movably coupled to one another; a wrist assembly having a distal end portion supporting the end effector; and a shaft defining a longitudinal axis and have a distal end supporting the wrist assembly. The wrist assembly includes a plurality of joint members rotatably connected to one another in tip-to-tail fashion, wherein each joint member defines a central rotational axis, and wherein adjacent joint members are rotatably connected to one another in a plane which is oriented at a non-orthogonal angle relative to the central rotational axes of the adjacent joint members. The wrist assembly includes also includes a plurality of concentric drive tubes extending through the plurality of joint members, wherein each drive tube includes a distal end keyed to a respective joint member.
