  • Patent number: 10058345
    Abstract: An endoscopic harvesting device removes a vessel from a body. The vessel has an anterior side closest to the skin. A sheath extends in a longitudinal direction with a dissector tip for advancing along the vessel substantially along the anterior side to create a flanking tunnel spaced away from the vessel. A ring-shaped blade is mounted to the sheath and is disposed in a plane substantially perpendicular to the longitudinal direction and proximal of the dissector tip. The blade forms a lateral loop to encircle the vessel from the flanking tunnel. The blade comprises an inductively-heated ferromagnetic member configured to make a vasiform cut including a pedicle around the vessel as the sheath advances.

  • Patent number: 9694164
    Abstract: A single stage instrument is used to insert a chest drainage tube into the inter-pleural space to facilitate drainage. The instrument is scissor-like with cylinder-like channels to slidably enclose the distal section of the tube therein when closed. The tip of the instrument is curved to enter the skin incision and the offset pleural incision whereafter the instrument is rotated 180 degrees to align the curved tip with the pleural space. The curved tip facilitates sliding the chest drainage tube through the instrument to effect sufficient insertion length. Once the instrument is in place, the tube is slid along the instrument to ensure that all drainage holes in the chest drainage tube are within the pleural cavity. Thereafter, the instrument is withdrawn leaving the chest drainage tube in place. After withdrawal of the instrument, it is opened laterally for lateral disengagement with the chest drainage tube.

    Abstract: In specific embodiments, a manipulator adapted to grasp and draw tissue comprises a first arm and second arm having proximal ends and distal ends separated by a distance. A first grasping surface and second grasping surface each connected to and extending from respective distal ends of the first and second arm are biased toward each other by a respective spring force. When the first arm and second arm are actuated to reduce the distance, tissue arranged between the first grasping surface and the second grasping surface resists the actuation. The first arm and second arm are then further actuatable to overcome the spring force of the first grasping surface and the second grasping surface so that the first grasping surface and the second grasping surface pivot at respective pivot points such that the distance between the distal ends of the first and second arms is reduced.

  • Patent number: 8926636
    Abstract: In some embodiments, an apparatus includes a handle and an elongate member coupled to the handle. The elongate member has a first portion, a second portion and a third portion. The first portion of the elongate member extends from the handle and defines a first longitudinal axis. The second portion of the elongate member extends from the first portion and defines a second longitudinal axis. The first longitudinal axis and the second longitudinal axis define a first angle and a first plane. The third portion of the elongate member extends from the second portion of the elongate member and defines a third longitudinal axis. The third longitudinal axis and the second longitudinal axis define a second angle and a second plane. The second plane is non-parallel with the first plane.

  • Patent number: 8926646
    Abstract: A tunneling device for creating a pathway in subcutaneous tissue of a person's body. The tunneling device includes a member having two ends, where each of the ends defines an insertion surface that facilitates the insertion of the ends into the subcutaneous tissue of the person's body. The tunneling device includes an interchangeable handle connectable to each of the ends. The handle defines a grasping surface and an opening. The opening is configured to receive either of the ends. The grasping surface enables a user to securely hold the handle with one hand to forcibly move the member through the subcutaneous tissue of the person's body to create the pathway in the subcutaneous tissue, and pull a cable of an implant device through the created pathway.

  • Patent number: 8920456
    Abstract: A vessel harvesting apparatus is provided for removing a vessel from a patient. An endoscopic instrument has a distal end with a vessel harvesting tip and has a proximal end with a handle. The endoscopic instrument has an insufflation channel adapted to receive an insufflation gas from a regulated source at the proximal end. The insufflation channel has an outlet at the distal end adapted to expel the insufflation gas subcutaneously in the patient. A damping device has a flexible bladder with an inside space in fluid communication with the insufflation channel. The inside space has a volume that varies between a rest volume and an inflated volume in response to an amount of insufflation gas flowing to or from the flexible bladder.

  • Patent number: 8852244
    Abstract: A dilator retractor and the dilators that are used for minimally invasive spinal surgery or other surgery are configured to accommodate the anatomical structure of the patient as by configuring the cross sectional area in an elliptical shape, or by forming a funnel configuration with the wider end at the proximate end. In some embodiments the distal end is contoured to also accommodate the anatomical structure of the patient so that a cylindrically shaped, funnel shaped, ovoid shaped dilator retractor can be sloped or tunneled to accommodate the bone structure of the patient or provide access for implants. The dilator retractor is made with different lengths to accommodate the depth of the cavity formed by the dilators.

  • Patent number: 8845671
    Abstract: A method and apparatus for preparing an access site on a patient for insertion of a catheter into one of the patient's veins. The method includes the steps of: providing a tract forming assembly having a leading cutting edge and a dilating body defining a trailing dilating portion, with the cutting edge and dilating body together defining a tract forming unit; advancing the tract forming unit into skin at the access site so that: a) the cutting edge progressively forms a tract through the patient's skin and subcutaneous tissue towards the one vein; and b) the dilating body follows the cutting edge and dilates the tract; and removing the tract forming unit from the dilated tract so that no component resides in the dilated tract to allow a catheter to be directed through the dilated tract and into the one vein.
