  • Patent number: 8034292
    Abstract: An automated machine for handling and embedding tissue samples contained on microtome sectionable supports. The machine includes an input member configured to hold a plurality of the microtome sectionable supports prior to a tissue embedding operation. An output member is configured to hold a plurality of the microtome sectionable supports after the tissue embedding operation. A cooling unit is configured to hold at least one of the microtome sectionable supports during the tissue embedding operation. A motorized carrier assembly is mounted for movement and configured to hold at least one of the microtome sectionable supports. The carrier assembly moves the support from the input member to the cooling unit and, finally, to the output member. A dispensing device dispenses an embedding material onto the microtome sectionable support and at least one tissue sample carried by the microtome sectionable support during the embedding operation.

  • Patent number: 7722642
    Abstract: Wire fasteners having legs with lengths that can be one hundred times the width of the fastener are used to secure items, such as prosthesis valves to a patient during minimally invasive surgery. The fasteners are manipulated into position and then are immobilized by means of the legs thereof for tensioning, cutting and forming in situ. The fasteners are manipulated, tensioned and formed from the leg end of the fasteners. Tools for initially placing the fasteners and for immobilizing, tensioning, cutting and bending the fastener legs are disclosed. Once the fasteners are initially placed, the prosthesis is placed on the long legs of the placed fasteners and is guided into position on the legs. Once the prosthesis is in position, the legs of the fasteners are immobilized, tensioned, cut and bent into staple-like shapes to secure the prosthesis to the patient. A method for carrying out the procedure using the long fastener is also disclosed.

  • Patent number: 7326177
    Abstract: Devices and methods are disclosed for stabilizing tissue within a patient's body during a surgical operation to provide a relatively motionless surgical field, such as during a coronary artery bypass graft procedure. The devices include tissue stabilizers which engage and provide stabilization to a targeted area of tissue and further have the ability to engage and manipulate some portion of tissue within or adjacent the targeted area to improve the surgical presentation of that portion of tissue. The tissue stabilizer typically has one or more stabilizer feet which have a first foot portion configured to provide stabilization to the targeted tissue and a second foot portion moveable relative to the first foot portion for manipulating a portion of tissue to improve the surgical presentation.

  • Patent number: 6042607
    Abstract: A heart valve can be replaced using minimally invasive methods which include a sutureless sewing cuff that and a fastener delivery tool that holds the cuff against the patient's tissue while delivering fasteners, two at a time to attach the cuff to the tissue from the inside out. The tool stores a plurality of fasteners. Drawstrings are operated from outside the patient's body and cinch the sewing cuff to the valve body. The cuff is releasably mounted on the tool and the tool holds the cuff against tissue and drives the fastener through the cuff and the tissue before folding over the legs of the fastener whereby secure securement between the cuff and the tissue is assured. At least two rows of staggered fasteners are formed whereby fasteners are located continuously throughout the entire circumference of the cuff. A minimally invasive surgical method is disclosed, and a method and tool are disclosed for repairing abdominal aortic aneurysms in a minimally invasive manner.
