Abstract: A vessel occluder is disposed inside a principal blood vessel for occluding tributary blood vessels inside the principal blood vessel while still allowing blood to flow through the principal vessel. The vessel occluder includes a support structure and associated membrane that can be collapsed for insertion into the principal vessel. Once inserted at the desired location the support structure is allowed to expand, forcing the membrane to contact the inner walls of the vessel with sufficient force to occlude the openings of the tributary vessels.

Abstract: An electro-stimulation device includes a pair of electrodes for connection to at least one location in the body that affects or regulates the heartbeat. The electro-stimulation device both electrically arrests the heartbeat and stimulates the heartbeat. A pair of electrodes are provided for connection to at least one location in the body that affects or regulates the heartbeat. The pair of electrodes may be connected to an intravenous catheter for transvenous stimulation of the appropriate nerve. A first switch is connected between a power supply and the electrodes for selectively supplying current from the power supply to the electrodes to augment any natural stimuli to the heart and thereby stop the heart from beating. A second switch is connected between the power supply and the electrodes for selectively supplying current from the power supply to the electrodes to provide an artificial stimulus to initiate heartbeating. In another aspect, the invention is directed to a method for arresting the beat of a heart in a living body comprising the steps of connecting the pair of electrodes to at least one location in the body that affects or regulates the heartbeat and supplying an electrical current to the electrodes of sufficient amplitude and duration to arrest the heartbeat. The device may also serve to still the lungs by input to a respirator or by stimulation of the phrenic nerve during surgical procedures.

Abstract: An arterial cannula which includes a diverting side hole which simultaneously perfuses blood to the body and the lower extremity. Two barbs on the cannula exterior position the diverting hole just inside the blood vessel and prevent the back wall of the blood vessel from blocking the diverting hole. A transparent flash chamber on the proximal end of the cannula provides a visual indication of the entrance of the diverting side hole into the blood vessel. When the diverting hole enters the blood vessel, blood immediately fills the flash chamber.

Abstract: An improved aortic cannula is formed from a cannula body and a tip provided on the distal end of the cannula body wherein the tip is designed to accommodate the fluid flow requirements of an extracorporeal bypass system while simultaneously minimizing any possible adverse impact of the cannula and fluid flow on the vessel in which the cannula is received. The tip has an axial fluid discharge aperture provided at the distal end thereof through which a portion of the fluid exiting the cannula flows. In addition, at least one lateral fluid discharge aperture is provided in the sidewall of the tip. A scoop or other diverting member is formed in the sidewall to direct a portion of the fluid flowing through the tip to exit the cannula through the lateral fluid discharge apertures.

Abstract: A two-staged venous cannula is disclosed. The cannula includes an expandable reinforcing member around the atrial basket that prevents the cannula from kinking or collapsing in the area where the reinforcing member is applied. The reinforcing member preferably consists of an even number of rigid discrete beams of the same length equally spaced about the circumference of a cylinder. In an alternate embodiment, the beams may be equally spaced on the surface of a cone. Alternate spaces between the beams are formed. The alternate spaces between the beams are equally spaced around the circumference of the cannula. The alternate spaces between the beams remain equally spaced around the circumference of the cannula as the reinforcing member is expanded over a larger diameter. This design for the reinforcing member provides space between the beams where holes of the preferred shape, size and orientation can be placed through the cannula without requiring cutting through the material of the reinforcing member.
