  • Patent number: 6811555
    Abstract: A ring for use in anastomosis. Preferably, the ring is integrally formed from metal, and includes a ring portion and tines and docking members that extend from the ring portion. The ring portion and tines are malleable, and preferably also the docking members are malleable. The ring portion and tines are malleable in the sense that once deformed from a first shape into a second shape, they will not relax back into the first shape from the second. To install the ring in a vessel with the ring portion extending around an incision or other orifice, the tines pierce the tissue around the orifice and are curled against an anvil. The action of curling the tines inverts the tissue near the orifice edges to expose the inside surface of the vessel or organ.

  • Publication number: 20040092798
    Abstract: A system for manipulating a heart during cardiac surgery links lifting of the heart and regional immobilization which stops one part of the heart from moving to allow expeditious suturing while permitting other parts of the heart to continue to function whereby coronary surgery can be performed on a beating heart while maintaining cardiac output unabated and uninterrupted. Circumflex coronary artery surgery can be performed using the system for manipulating a heart during cardiac surgery of the present invention. The system is an improvement on the retractor disclosed in parent application Ser. No. 08/936,184 filed on Sep. 17, 1997 and locates a suspension head near the apical region of the heart and a gross support near the base of the heart near the AV groove.

  • Publication number: 20040016776
    Abstract: A cap for curable material dispensing containers prevents the material from curing after opening the dispensing nozzle. Thus, when mounted on a partially-dispensed container, the nozzle cap preserves flowable materials such as air-cured glues, sealants, caulks, etc. In particular, a deformable sealant in the cap remains pliant, conforming in and/or around the nozzle tip to create a seal. A retention member frictionally grips the nozzle to prevent inadvertent release of the cap, yet accommodates nozzle tips cut to varying lengths.

  • Publication number: 20030153932
    Abstract: An anastomosis is performed using a flexible mounting structure mounted on the outside of at least one vessel. Fasteners extend through the vessel and are bent towards the incision to attach the flexible mounting structure to the vessel in a manner that controls the edge of the vessel adjacent to the incision. The mounting structures are oriented on each vessel so fasteners on one mounting structure interdigitate with fasteners on the other mounting structure at the location of contact between the vessels when the two vessels are brought together. This creates two complementary sinusoidal-shaped vessel edges with peaks of one edge being accommodated in the valleys of the other edge. The peak-to-valley orientation forms a sinusoidal-shaped joint which is leak free. The fasteners are spaced so proper pressure is applied to the tissue to promote healing without leaking. Furthermore, the fasteners are sized and shaped to properly engage the tissue and bend in a desired manner.
