Filed:

Jun 9, 1986

Appl. No.:

6/872124

Inventors:

Charles C. Reed - Houston TX

International Classification:

B01D 1900

US Classification:

210188

Abstract:

A novel cardiotomy reservoir apparatus and method for use in an extracorporeal blood circuit which provides for the effective defoaming of blood that has been aspirated from a patient during surgery. The apparatus includes an outer receptacle, which is preferably generally cylindrical in shape, the receptacle having at least one inlet formed in the top thereof, an outlet formed in the bottom thereof, and a vent port. The receptacle contains a defoaming means which substantially occupies the entire interior volume of the receptacle, and which has an increasing density in the direction of blood flow through the receptacle. In addition, the cardiotomy reservoir of the present invention may be used with an external blood filter and the outlet of the reservoir receptacle has a valve formed therein to facilitate rapid and safe replacement of the external filter in the event that it becomes occluded.

International Classification:

US Classification:

Abstract:

A blood oxygenator having two separable components one of which is disposable and the other of which is reusable and sterilizable. The disposable portion of the oxygenator is multichambered and provides an oxygenating chamber, a defoaming chamber and an arterial reservoir constructed so that blood will flow sequentially therethrough. The reusable member is constructed in the form of a cover for the oxygenator and has depending therefrom a heat exchanger for maintaining the temperature of the blood, the heat exchanger projecting telescopically into the oxygenating chamber. Defoaming is assisted by a cellular foam material rolled into a generally cylindrical configuration and having abutting faces which are bias cut so that the line formed by the abutting faces is not coaxial with the blood flow path. The device is assembled by inserting the defoaming material into the defoaming chamber of the open-topped oxygenator, then telescopically inserting the heat exchanger into the oxygenating chamber while placing the cover on the top of the oxygenator and thereafter removably securing the cover to the oxygenator.

US Classification:

128347

Abstract:

A device for aspirating air emboli from a blood vessel (e. g. the aorta during open-heart surgery), the aspirating device having a hollow cannula with radially spaced openings for aspirating air and bending angularly mid-length to permit aspiration of air emboli while maintaining the device generally flat against the exposed patient surface. A hub comprising part of the device is constructed to provide a dual coupling presenting both male and female attachment sites.

Abstract:

A surgical equipment tray inexpensively fabricated from a sheet of rigid plastic material. The tray has an absorbent, lint-free surface which (1) absorbs fluids, (2) provides a nonskid instrument surface, and (3) attenuates the noises associated with handling instruments on the tray. Longitudinal ridges and grooves may be included in the base of the tray to provide rigidity to the tray and elevate or expose the instruments for easy access.

Abstract:

A suction wand having a weighted, reusable handle in cooperation with a disposable suction conduit, the suction conduit having a suction tip at one end and adapted to couple with a suction tubing at the other end. The weighted handle imparts a pre-selected weight and feel to the wand and is selectively reusable with a variety of disposable suction conduit systems.

Abstract:

A heart valve prosthesis incorporating a dynamic stiffener element is disclosed. The prosthesis is adapted for securement to the annulus of an atrioventricular valve and has the characteristic of allowing normal movement of the annulus during the cardiac cycle while providing mechanical support to the valve annulus so as to maintain the valve leaflets in proper physiological alignment. The stiffener element has a plurality of reciprocating members allowing it to be modifiable in shape so as to be capable of assuming the optimum shape for a particular heart valve.
