    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: An intravascular balloon occlusion device according to the invention is shown. The device is ideally suited for use in a coronary artery bypass graft procedure. The device includes a body having at least one selectively inflated balloon provided on the distal end thereof. Preferably, the body is a closed end body so that fluid can only flow from the proximal end of the body into the balloon. In use, the distal end of the body and the balloon are inserted into an aperture provided in the aorta. The balloon is inflated and then the device is retracted until the balloon seats against the incision or aperture in the aorta, thereby effectively sealing the aperture from the blood flow through the aorta, but not occluding blood flow through the body of the aorta itself. Next, the graft vessel is telescopically positioned on the occlusion device and mounted to the aorta. Once the vessel is secured thereto, the balloon is deflated and then the occlusion device is retracted from both the aorta and the graft vessel. Finally, the second end of the graft vessel is mounted to the appropriate coronary artery.

    Abstract: An intravascular pump and balloon catheter assembly is shown. The assembly includes a primary catheter having a balloon provided thereon and an intravascular pump provided therein. The pump is adapted to generate a pressure differential between the inlet of the catheter and the outlet. With this structure, fluid is supplied, under pressure, to multiple arteriotomy cannulae provided at the terminal end of the assembly. The cannulae are inserted into blood vessels at appropriate points so that an occlusion or restriction in a blood vessel can be bypassed while still maintaining blood flow throughout the body.

    Abstract: An apparatus for the sanitary simultaneous removal of a plurality of indwelling tubes from an implantation site in a patient comprises a tube adapter that is connectable to the indwelling tubes. An impervious sleeve is fan-folded into a hub which extends around the tube adapter. In assembly the folded sleeve is retained by a shrink-wrapped plastic film. The sleeve can be extended for receiving the indwelling tubes therethrough and to encompass the implantation site. The indwelling tube and the implantation site are isolated from the environment when the distal open end of the sleeve is extended and applied about the implantation site and the indwelling tube is withdrawn into the sleeve. A drawstring is provided for closing the distal end of the sleeve after the tube has been withdrawn. The indwelling tubes can be maintained under suction or in connection with a drain during the removal operation.

    Abstract: There is disclosed an apparatus comprising a hub that includes an annular container disposed about a central aperture for receiving an exterior portion of an indwelling tube therethrough to engage a bottom portion of the container in sealing contact with the implantation site. An extensible impervious membrane is folded within the container and is in sealing contact therewith, the membrane being arranged to form an open sleeve for receiving the tube and being coextensible therewith during withdrawal of the tube. A tie is provided to seal the sleeve about the exterior wall of tube, leaving the free end of the tube accessible to the operator. The indwelling tube can then be withdrawn through the central aperture into the coextending closed sleeve. A plastic film that adheres to the bottom portion of the container is provided for closing the central aperture to enclose the removed tube in the sleeve.

    Abstract: A device for continuously monitoring the output of a heart in a surgical patient includes a probe head attached at one end to a catheter adapted to be inserted into the patient. The probe head includes a probe and a pair of flexible flat projections extending outwardly from opposite sides of the probe for securing the probe head in the transverse sinus of the patient. At least one transducer is positioned in the probe for detecting a condition of the heart. A hollow needle is adapted for receiving the probe head prior to its installation in the patient, such that the probe head can be installed in the patient immediately after mediansternotomy and division of the patient's pericardium by inserting the needle through the patient's chest wall. A method for continuously monitoring the condition of the heart in a surgical patient includes the steps of providing a probe head responsive to heart function; positioning the probe head in the transverse sinus of the patient proximal to the aortic valve and behind the ascending aorta; and displaying an output of the probe head reflective of the heart condition.
