  • Patent number: 8641641
    Abstract: A tissue harvesting and processing apparatus comprises a body and a distally extending needle. The needle includes an aperture configured to receive tissue. A tissue cutting member is movable relative to the needle to sever a specimen from tissue protruding through the aperture. A tissue processor is operable to mince tissue severed by the tissue cutting member. The minced tissue may be mixed with a medical fluid component contained in a reservoir. The medical fluid mixture may be expelled through an applier tip coupled with the body. The tissue processor may comprise a mincing die such that tissue specimens are minced upon being extruded through the mincing die. The tissue processor may comprise a blade that cooperates with a sliding press. The tissue processor may comprise auger blade sections that cooperate with inwardly extending pins. A mixing piston may mix the minced tissue with the medical fluid component.

  • Patent number: 8585724
    Abstract: A surgical instrument includes first and second cutting blades, each including a tubular body having proximal and distal ends, with a cutting window disposed at a side of each cutting blade near its distal end. The second cutting blade rotates within the first cutting blade to cut tissue while a vacuum is applied through an internal bore of the second cutting blade. The distal end of each of the cutting blades includes a suction aperture. An area of the first cutting blade suction aperture is smaller than an area of the second cutting blade suction aperture. The instrument is used as a suction tool by applying the vacuum through the internal bore of the second cutting blade while the second cutting blade is stopped from rotating with the cutting windows of the first and second cutting blades misaligned with each other to apply the vacuum through the suction apertures.

  • Patent number: 8585726
    Abstract: The disclosure provides a tissue removal device including customizable tips. The tissue removal device may include an outer shaft and a threaded shaft. One aspect of disclosure may include a shaft cutting tool that emerges from the end of the outer shaft. Another aspect of the disclosure may include a flexible cutting blade extending from the threaded shaft. Threaded shaft may be driven by a driving mechanism in order to provide an auger-like suction mechanism to facilitate the transfer of removed tissue to a collection chamber that is coupled to the outer shaft and the threaded shaft.

  • Publication number: 20130304106
    Abstract: A transseptal punch with a steering mechanism within the punch, such that punch can be steered and deflected within a guide catheter during delivery, to avoid skiving of the guide catheter inner wall by passage of the punch tip through the guide catheter. The punch can be advanced through a body lumen in its straight configuration and then be selectively articulated or curved to permit negotiation of tortuous curvature or to permit optimal approach or access to a puncture site. The punch is able to create holes in the atrial septum of the heart or other structures and is easier to use than punches that are pre-curved near their distal tip since it is easier to advance through accessory catheters.

  • Patent number: 8579930
    Abstract: A surgical instrument for use in releasing soft tissue within the human body. The surgical instrument has a handle with proximal and distal ends with a tube connected to the distal end. The surgical instrument also includes a blade member that slidingly engages the tube moving along the length of the tube to cut soft tissue. Further included in the surgical instrument is a guard member that is attached to the blade member. The guard member has a hood portion and a capture portion. The hood portion is connected to the blade member with the distally positioned capture portion acting to displace surrounding tissue while capturing certain soft tissue structures resulting in the blade member being in operative position to cut and release the soft tissue. A surgical instrument kit including a plurality of modular surgical instruments and method for releasing soft tissue using the surgical instrument are also disclosed.

  • Publication number: 20130296909
    Abstract: A surgical instrument for cutting and grasping tissue comprising a handle assembly, an elongated member and first and second jaws. A first movable member moves the second jaw in a first direction about a first pivot axis in a grasping action and a second movable member moves the second jaw in a second direction different than the first direction and about a second pivot axis in a cutting action. A switch is positioned at the proximal portion of the instrument and a selecting member is actuated by movement of the switch, the selecting member movable between a first position to enable movement of the second jaw in the first direction and prohibit movement in the second direction and a second position to enable movement of the second jaw in the second direction and prohibit movement in the first direction.

  • Publication number: 20130296910
    Abstract: A surgical tool system with a handpiece and a cutting accessory that has inner and outer hubs. The handpiece has a spring biased lock ring that abuts a complementary stop member integral with the accessory outer hub to hold the accessory to the handpiece. An RFID chip is disposed against an inner wall of the accessory outer hub. An elastomeric seal pressed against the inner wall of the accessory outer hub provides environmental protection for the RFID chip. The seal has a rib that extends around the outer perimeter of the proximal end of the outer hub so as to form a seal between the accessory and an adjacent inner wall of the handpiece. Stop tabs extend inwardly from the seal to prevent the drive hub disposed inside the outer hub from falling out.

  • Publication number: 20130296854
    Abstract: An end effector assembly for use with a forceps includes a pair of jaw members, a knife assembly, and one or more cam assemblies. One or more of the jaw members are moveable relative to the other about a pivot between open and closed positions. One or more of the jaw members include a knife channel. The pivot includes first and second sections defining a passage therebetween. The knife assembly includes a knife blade and an actuation shaft. The knife blade is disposed distally relative to the pivot. The actuation shaft is configured for slidable translation through the passage to allow selective advancement of the knife blade through the knife channel. The one or more cam assemblies are operably coupled to the one or more moveable jaw members and are actuatable to move the one or more jaw members between the open and closed positions for grasping tissue therebetween.

  • Publication number: 20130289597
    Abstract: A method and apparatus for transecting soft tissue, such as a ligament, and more particularly, the transverse carpal ligament. An hollow introducer needle and a threadlike cutting element enable the method to performed in a minimally invasive manner. The cutting element is routed into position about the target ligament such that the cutting element both enters and exits the body from the same side of the ligament. The substantially smooth exterior surface of the cutting element serves to provide for a kerf-less cut.

  • Publication number: 20130289595
    Abstract: A surgical instrument has a hollow tubular member, and a pressurization unit that has an outer valve portion, a pressurization device having a movable part configured to generate pressurized fluid when the movable part is moved, and an inner valve portion. The inner valve portion includes a first flow passage that is configured to connect a first port and a second port of the outer valve portion to each other when the inner valve portion is in a first position, and a second flow passage that is configured to connect the first port of the outer valve portion to the pressurization device when the inner valve portion is in a second position. Pressurized fluid from the pressurization device causes the inner valve portion to move from the first position to the second position, thereby providing positive pressure to the hollow tubular member.
