A tendon stripper includes a stripping device and a rod. The stripping device includes a stripping member and at least one coupling member coupling to the stripping member. The stripping member has a blade portion and a separating portion separating the stripping member into several parts. The rod has a handle end and a coupling end opposite to the handle end. The coupling end couples to the coupling member of the stripping device. The separating portion allows the stripping member to be divided into first and second parts, and the first and second parts can be combined to each other to jointly receive the tendon. This avoids the generation of the incisions during the tendon transplantation. In addition, since the tendon stripper does not require any instrument for retaining the free end of the tendon, a convenient surgical procedure is provided.

A length indicator for use with a minimally invasive surgical device for vessel harvesting includes a shaft that extends along a shaft axis, and a tether is disposed at a first end of the shaft, the tether being configured to be coupled to the minimally invasive surgical device. A plurality of reference tabs extend from the shaft, and each of the plurality of reference tabs extend along a tab axis. A first distance along the shaft axis separates a tab axis of a first of the plurality of reference tabs and a tab axis of a second of the plurality of reference tabs, and a second distance along the shaft axis separates the tab axis of the second of the plurality of reference tabs and a tab axis of a third of the plurality of reference tabs, with the first distance being equal to the second distance.

A vessel harvesting apparatus for removing a blood vessel from a patient includes collection and conditioning (i.e., treatment) of expelled insufflation gas prior to releasing the gas into the air of the operating room. An endoscopic instrument has a distal end with a vessel harvesting tip and has a proximal end with a handle. An insufflation channel is configured to convey an insufflation gas subcutaneously into a dissected space within the patient. A removal channel is configured to evacuate fluidic contents from the dissected space, wherein the fluidic contents include insufflation gas and biological impurities. A processor/separator is coupled to the removal channel to process the fluidic contents to retain at least some of the biological impurities and to exhaust the insufflation gas.

A system for improving graft harvesting including a blade guide (320) having a handle (370) and a guide portion with an elongate slot (330). The system may also include a first blade assembly (750) that slides along the elongate slot (330), the blade assembly (750) having a cutting blade (765) rotatably coupled to a handle (780). The cutting blade (765) may include a leading cutting edge and a trailing cutting edge. The blade assembly (350, 750) and blade guide (320) may cooperate to control a depth of blade penetration into a tissue, as the blade slides along the elongate slot (330). The blade guide (320) may include means to stabilize the guide with the tissue.

The presently disclosed embodiments relate to insufflation and irrigation conduits for vessel harvesting systems and methods of their use. In particular, the present disclosure relates to a system having a combined cabling for providing gases, liquids, and/or electrical power to an attached medical device and method of use.

A method of treating a vessel in a subject comprises the steps of advancing a device distally across a treatment zone in a vessel, wherein the device comprises an elongated catheter having a lumen and a distal end, and a radially expansive treatment element disposed in the lumen and configured for axial movement relative to the catheter; deploying the radially expansive treatment element proud of the distal end of the catheter to radially expand and circumferentially impress against the vessel lumen at a distal end of the treatment zone; and withdrawing the deployed radially expansive treatment element proximally along the treatment zone with the treatment element circumferentially impressed against the vessel lumen to mechanically and circumferentially denude the treatment zone of the vessel. The radially expansive treatment element is then recaptured into the lumen of the catheter, before the device is withdrawn from the treated vessel.

Devices and methods for extraction and processing of substantiagelatineafuniculi umbilicalis (Wharton's Jelly) from an umbilical cord.

Surgical instruments and methods of minimally invasive surgery are provided. The device may include two proximal handles each sized for a surgeon's hand, the two handles in fixed relative positions, and a distal probe attached to the handles. The probe can include a distal cutting member and contain or receive an imaging device. The system can be used for cutting anatomic members, such as ligaments, during minimally invasive surgical procedures, for example, performing endoscopic ligament release surgery, such as carpal tunnel release, plantar fasciotomy, gastrocnemius release, cubital tunnel release, and tarsal tunnel release surgery, and similar surgical procedures on anatomic members.

An endoscopic vein harvesting system may include an endoscope including a proximal end having one or more of a collar or a handle and including a distal end. The system may include a component formed from a transparent material and configured to couple to the distal end of the endoscope. The system may include one or more visual indicators formed on or within a selected portion of the component. In some implementations, the one or more visual indicators may assist a harvester to determine a position of the component relative to a vein to be harvested.

An endoscopic vessel harvesting tool uses an optics system to present of a video image to a user. As the tool is manipulated around all sides of the vessel to dissect and cut surrounding tissue and side branches, the orientation of the captured image rotates. A motion tracker (e.g., gyrosensor) in the tool detects the rotation. By detecting a rotational angular velocity of the harvester handle during the harvesting procedure, the camera view orientation is compensated before display to the user. When the handle is rotated, the detected rotation is used to provide an opposite (canceling) rotation of the camera view so that a steady orientation is presented on the display. Thus, a vertically upward direction (or any other desired reference direction) remains substantially fixed in the displayed video images.
