Cutting Patents (Class 600/564)
  • Patent number: 10405877
    Abstract: A system and method for removing a tissue specimen or organ from the body of patient is disclosed. The system includes a bag and an excising instrument. The tissue specimen or organ is located in the bag, which is located in the patient's body. The instrument comprises a guide and a cutter. The guide is configured for introduction into the bag. The cutter is rotatable within the guide and includes a central passageway and an annular cutting blade. The cutting blade is brought into engagement with a peripherally located portion of the tissue specimen and rotated to produce a tangentially cut peripheral portion while a pulling force is applied to the tissue specimen through the central passageway. The pulling force rotates the tissue specimen within the bag to effect the production of the tangentially cut peripheral portion and to move the tangentially cut peripheral portion out of the patient's body. Gas pressure may be applied to inflate the bag to facilitate placement of the excising instrument.

    Abstract: A catheter-based device tracks over a guidewire which has been placed from a first blood vessel into a second blood vessel. The distal tip of the catheter is advanced into the second vessel while a proximal member remains in the first vessel. Matching blunt tapered surfaces on each of the distal tip and the proximal member are clamped together, with adjacent walls of each vessel between them, after which a known, controlled pressure is applied between the two surfaces. Heat energy is then applied to the blunt surfaces for approximately 1-30 seconds to weld the walls of the two vessels together. After coaptation of the vessel walls, the heat is increased to then cut through the vessel walls to create a fistula of the desired size.

The end effector comprises a staple cartridge and a firing member which is displaced distally to staple the patient tissue in response to at least one actuation motion applied at the housing. The surgical device further comprises a flexible actuator extending along the shaft axis such that selective actuation of the flexible actuator causes articulation of the end effector. The flexible actuator is operably coupled between the end effector and the rotator. The firing member extends through the elongate shaft.

    Abstract: An excisional device for either handheld or stereotactic table/MRI use may comprise a work element configured to rotate at a first rotation rate and comprising at least one articulable beak configured to cut tissue in a longitudinal direction. Helical elements or equivalent assemblies may be configured to transport tissue cut by a work element and may be co-axially disposed relative to the work element and may be operative to rotate at rotation rates that may be different from the work element rotation rate. Flush and vacuum tissue transport mechanisms may be incorporated in replacement of or in conjunction with helical elements. A proximal sheath and a distal sheath may be co-axially disposed relative to a work element and may be configured to rotate a work element and to actuate a beak or beaks. A simplified embodiment of this device may be applicable to field use where power sources for actuation may be limited.

  • Patent number: 10028749
    Abstract: The present disclosure provides an apparatus, and methods of using same, for collecting blood from an umbilical cord in a sterile environment that includes an umbilical cord retaining assembly and a blood collection assembly rotatably connected to the umbilical cord retaining assembly. A cord cutting blade, which is carried by the blood collection assembly, functions to cut the umbilical cord when the blood collection assembly is rotated relative to the umbilical cord retaining assembly. After the umbilical cord is cut, blood flows by force of gravity into the blood collection region of the blood collection assembly to which a blood collection bag can be interconnected.

  • Patent number: 10022183
    Abstract: The present invention provides an irrigated ablation electrode that includes a plurality of high L/d interior fluid passageways and/or slit-shaped apertures to provide for a lower rate of fluid flow and a more uniform distribution of fluid over an exterior surface of the electrode and reduce propensity for aperture blockage. In some embodiments, the slit-shaped apertures have an aspect ratio of at least three, at least five, at least ten, or at least fifteen. Some embodiments include maintaining a pressure drop of at least 345 pascals between irrigation fluid inside the irrigated ablation electrode and fluid immediately outside the electrode when the irrigation fluid has a flow rate of no more than five milliliters per minute (5 ml/min). Some embodiments include a low-density insert with a plurality of fluid channels on its exterior surface to more efficiently cool the electrode and provide a faster thermal response.
