  • Patent number: 10823398
    Abstract: A torch igniter and a method of igniting a torch flame. An example embodiment includes a body including an oxidizer inlet configured to facilitate oxidizer flow through the body toward an output end of the body. The body includes a group of fuel inlet passages configured to distribute fuel in a direction tangential to the oxidizer flow through the body to create a swirling fuel-oxidizer mixture. A sparking element can be mounted on the body to produce a spark in the path of the swirling fuel-oxidizer mixture to ignite the mixture. The output end of the body is configured to emit a torch flame when the fuel-oxidizer mixture is ignited. Thus, a swirl torch igniter is configured for oxidizer and fuel flow through the igniter body to create an internal swirling fuel-oxidizer mixture to be ignited by a sparking element.

  • Patent number: 6972023
    Abstract: Distal anastomosis devices and associated methodology are described herein. Connector and connector components as well as tools associated therewith are disclosed. The connectors are preferably adapted to produce an end-to-side anastomosis at a graft/coronary artery junction. A fitting alone, or a fitting in combination with a collar may be used as a connector. Each fitting may be deployed by deflecting its shape to provide clearance for a rear segment that rotates about adjoining hinge section(s) so to fit the connector within an aperture formed in a host vessel. Upon return to a substantially relaxed position, a rear segment anchors the fitting it in place. The distal fitting may include additional side features for interfacing with the host vessel/coronary artery. The collar may include features complimentary to those of a fitting and provisions for securing the graft vessel.

  • Publication number: 20030229365
    Abstract: Angled anastomosis devices and associated methodology are described herein. Connector and connector components as well as tools associated therewith are disclosed. The connectors are adapted to produce an angled end-to-side anastomosis at a graft/host vessel junction. A fitting alone, or a fitting in combination with a collar may be used as a connector. Each fitting may be deployed by deflecting its shape to provide clearance for a rear segment that rotates about adjoining hinge section(s) so to fit the connector within an aperture formed in a host vessel. Upon return to a substantially relaxed position, a trailing or heel segment anchors the fitting in place. The angled fitting may include additional side features for interfacing with the host vessel. The collar may include features complimentary to those of a fitting and provisions for securing the graft to the host vessel.

  • Patent number: 6494904
    Abstract: A vascular prosthesis (10) comprises pericardial, fascial, or other tissue (12) formed over a tubular support frame. A first exemplary tubular support frame comprises an inner helical member (16) and an outer helical member (14), where the tissue is rolled and captured therebetween. A second exemplary tubular support frame (60, 62) comprises a plurality of ring elements (64, 72) which are located alternately on the outside and on the inside of the rolled tissue. Other exemplary frames employ fasteners (84, 98) for penetrating the rolled tissue and attaching tissue to frame elements. The tissue is preferably obtained from the patient who is to receive the vascular prosthesis, with the tissue being mounted over the frame immediately prior to use.

  • Patent number: 6374866
    Abstract: A system and apparatus are disclosed for preparing tubular prostheses from a sheet of tissue and inner and outer helical frame components. The tissue is wrapped around the inner frame component over an assembly mandrel. The outer helical frame component is then transferred from an elongate support over a lead screw, onto the assembly mandrel by rotating the assembly mandrel and lead screw in a manner which positions the outer helical frame component in an appropriate manner. Optionally, the mandrel is collapsed to facilitate removal of the completed tubular prosthesis.

  • Patent number: 5755782
    Abstract: An improved set of stents for autologous tissue heart valves is provided. The stents are designed with the aid of a computer-aided-design (CAD) system, and nest within each other to securely clamp a piece of tissue which forms the leaflets of the heart valve. The geometrical features of the stents are designed to provide uniform nesting between the stents to prevent the formation of stress raisers on the tissue. Additionally, the windows in the stent posts are narrowed to prevent the suturing needle used during implantation of the valve from becoming lodged in the garter springs which clamp the outer stent to the inner stent. Finally, the sock covering the outer stent is bonded to the stent base at both upper and lower locations to isolate the bonds from the patient's blood flow.

  • Patent number: 5697382
    Abstract: A method of assembling a heart valve is provided for use with an inner and a spreadable outer stent. The outer stent is mounted onto a spreading tool including a spreading ring, and expander, and a plunger. A protective cap is placed over the outer stent and plunger to prevent relative rotation of the outer stent to the expander prior to the complete spreading of the outer stent. The inner stent, with tissue wrapped thereon, is mounted onto an insertion tool including a mandrel having a plurality of guide rails for mating with slots of the spreading ring, wherein the guide rails in the slots provide axial and radial alignment of the inner and outer stents. The mandrel holding the inner stent is inserted through the spreading ring holding the outer stent, thereby releasing the mated stents from the spreading ring and mandrel and securely clamping the tissue between the stents.

  • Patent number: 5662705
    Abstract: A method of manufacturing and testing a tissue heart valve during open heart surgery is disclosed. A piece of autologous tissue from the body of the patient is precisely cut according to the size of the open annulus remaining after excision of the patient's heart valve, with a plurality of holes being formed in the tissue. The tissue is situated between appropriately selected first and second stents so that the holes are registered with corresponding tissue alignment members in one of the stents, and the stents are positioned together to securely clamp the tissue therebetween. The constructed tissue heart valve is then mounted in a test chamber and visually inspected for leakage.

  • Patent number: 5653749
    Abstract: This invention relates generally to a rapid assembly, concentric and flexible mating stent, tissue heart valve which can be assembled from prefabricated, sterile kits by a non-surgeon in the limited time available in an operating room. The kits provide the necessary tools and apparatus for harvesting the tissue and measuring the open annulus within the patient's heart. In addition, the kits contain size-specific components to be used during the rapid manufacture of the tissue heart valve.

  • Patent number: 5612885
    Abstract: A method for constructing stents for autologous tissue heart valves is provided. The method includes creating a stent profile primitive which is rotated about a first axis to create a solid stent blank having inner and outer surfaces. First and second splines are created and intersected with the inner and outer surfaces, respectively, to form a plurality of planes. Posts are formed on the stent blank by removal of material above the planes, and filleting is performed to provide a smooth upper surface for each post. Additional features corresponding to whether the stent is an inner or an outer stent for the heart valve are added, and the final stent shape is input into machine tooling which cuts an electrode into the corresponding stent shape. The electrode is then used to dissolve a pattern into a block of metal, such as a nickel-steel alloy, to form the final mold of the stent.

  • Patent number: 5609600
    Abstract: The present invention provides a novel tissue cutting device which accurately cuts the tissue to a predetermined configuration in a minimal amount of time, and where the tissue may then be used in an autologous heart valve. The disposable tissue cutting die of the present invention is comprised of a cutting die assembly and a cutting base assembly. The cutting die assembly retains a continuous blade with razor sharpened edges that enclose a desired spatial configuration. The cutting base assembly includes a rotatable cutting pad on which the tissue to be cut may be placed. The cutting die assembly and cutting base assembly are adpated to cooperate to cut the tissue when the cutting die assembly is inserted into the cutting base assembly and rotated approximately 180 degrees.
