US Patent:

39585573, May 25, 1976

Filed:

Mar 10, 1975

Appl. No.:

5/556613

Inventors:

Russell G. Sharp - Sugar Land TX
Denton A. Cooley - Houston TX
Charles C. Reed - Houston TX

Assignee:

Texas Medical Products, Inc. - Houston TX

International Classification:

A61B 1900
A61F 124

US Classification:

128 1R

Abstract:

A device and method for preparation and testing of a blood vessel such as the saphenous vein for use as a coronary bypass graft. The device includes a hollow body portion and a hollow stylet projecting therefrom. The stylet presents a peripheral flange facilitating temporary ligation of the vein upon the catheter. The body has a Luer fitting to accommodate coupling with a conventional syringe.

International Classification:

A61M 103

US Classification:

29157R

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.

International Classification:

A61B 1734
A61M 100

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.

US Classification:

206557

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.

International Classification:

A61M 100

US Classification:

128276

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.

Assignee:

Texas Medical Products, Inc. - Houston TX

International Classification:

A61M 100

US Classification:

128276

Abstract:

The disclosed surgical suction wand assembly and method includes a modular suction wand including a hollow suction tip the interior of which has a square or other suitable polygonal cross-sectional configuration which substantially improves the precision and facility with which apertures may be formed in the suction tip. The tip may be provided with an elongated interiorly disposed tube simultaneously providing for effective aspiration of small amounts of liquid as well as a large suction area for efficiently aspirating larger volumes with minimal opportunity for obstruction. The suction tip is provided with a coupling device adapted to receive any one of a plurality of adaptor configurations constructed so as to increase the versatility of the suction tip without requiring large numbers of separate forming molds.
