  • Patent number: 4741328
    Abstract: A method and apparatus to provide an improved cardiac assist by the use of a new form of intraaortic balloon are described. A single small balloon may be placed in the ascending aorta close to the aortic valve, such a placement being effective to produce a substantially stronger augmentation of heart action than with the use of a longer balloon mormally placed, for example, in the descending aorta. Multiple small balloons positioned in the aortic arch, with or without a large balloon in the descending aorta, can be used to provide even stronger coronary flows. The external diameter of the balloons in their inflated condition should in all events never be so great as to block the aorta, even when the latter may become contracted. Further improvements include an external control portion adapted to permit redirection of the assist and simultaneous and continuous measurement of blood pressure.

  • Patent number: 4703752
    Abstract: A contraceptive device for females comprising a toroidal collar having an anterior portion, a posterior portion, an internal wall, and an external wall, the internal wall having an internal diameter sufficient to surround the cervix and the external wall having an outside diameter such that the anterior and posterior fornices are substantially filled by the collar. The posterior portion is in the posterior fornix and the anterior portion is in the anterior fornix. There is a bowl, below the cervix, on the collar and extending downwardly therefrom. A valve depends from the lower portion of the bowl and is connected therewith, thereby to allow flow from said bowl into the vagina but restricting or preventing entry into the bowl from the vagina. A projection is attached to the collar or the bowl extending anteriorly of the device, whereby reversal of the device and/or substantial rotation thereof around the cervix is prevented. It also assists in removal thereof.

  • Patent number: 4527549

A single small balloon may be placed in the ascending aorta close to the aortic valve, such placement being effective to produce a substantially stronger augmentation of heart action than with the use of a longer balloon normally placed, for example, in the descending aorta. Multiple small balloons positioned in the aortic arch, with or without a large balloon in the descending aorta, can be used to provide even stronger coronary flows. The external diameter of the balloons in their inflated condition should in all events never be so great as to block the aorta, even when the latter may become contracted.

  • Patent number: 4491986
    Abstract: A prosthetic heart valve including a supporting structure comprising a substantially semi-circular base or armature of semi-rigid but somewhat flexible material with two upwardly projecting struts. The armature and struts may be encased with plastic or other suitable material; and are covered with soft flexible material including a strip which connects the free ends of the semi-circular base to form a complete ring. A membrane of biological or biologically acceptable material is shaped about the supporting structure so as to define a cylindrical orifice having lips which overlap, over a significant part of their inside surfaces, to provide a complete and effective closure against and under the force of back-flow. When said lips open the flow is relatively unobstructed. The soft strip of material which completes the armature ring permits the valve to respond more readily to movements of the heart while the semi-rigid section provides adequate support for the valve.

  • Patent number: 4423730
    Abstract: A device and procedure are provided which enable the attachment of a hollow cylindrical atriotomy button to, for example, the atrial appendage. The inventive device, which carries on its end the inner portion of an atriotomy button, is inserted through an incision in the hollow organ. When the device is triggered, the outer portion of the atriotomy button is forced over the inner portion. Sharp points, which are formed on the edge of the inner section, grasp and guide the walls of the incision during the operation of the device so that the walls are effectively clamped between the two button portions. After the button is in place, a cannula can be inserted into the heart through the access button or attached to the outer surface of the outer button portion.

  • Patent number: 4381771
    Abstract: A female contraceptive, cervical cover, including a dome-like main portion which is shaped to cover the cervix, long extending lips which form a one-way valve to permit waste material to flow out of the cervix and an outwardly biased collar which holds the cover securely to the walls of the vagina surrounding the cervix, without exerting any substantial pressure on the cervix.

  • Patent number: 4279248
    Abstract: A sternum closure device is provided by a series of upper and lower clamping devices which are held by a series of threaded rod from a support. The device is used for holding together the halves of a split sternum which has previously been cut to expose the chest cavity as required for example in heart operations. The lower clamping device is positioned beneath the sternum which is then pulled together in a known manner. The upper clamping device or clamps are then pushed down on a threaded rod to cooperate with the lower clamping device with the two clamping members forced toward one another into the sternum halves by nuts on the threaded rods. The unused portion of the rods and the support are then discarded. Different forms of under-clamps are described. A sternum closure procedure utilizing the sternum closure device is also disclosed.

  • Patent number: 4275469
    Abstract: A prosthetic heart valve consists of a tubular membrane having a flexible generally circular inlet end adapted to be attached to the annulus of a heart with one side of the tube held to the heart cavity as by attachment to the papillary muscle while the other side of the tube is formed as an extended single flap adapted to move toward and away from the membrane on the attached side to provide a closed or open valve at the outlet end.

  • Patent number: 4185636
    Abstract: A plurality of organizers each formed with an arcuate support member upon which a selected number of suture holding devices are positioned in spaced relationship one to the other, are each designed to be disposed proximate an area of a body upon which surgery is to be performed to faciliate speedy and orderly control of interrupted sutures and needles utilized during the surgical procedure. Each holding device includes a pair of spaced wall members and a resilient holding member disposed in compression therebetween in such a manner that sutures can be releasably held between the resilient member and the adjacent wall member surface. Additional valuable time for surgical procedures involving insertion of artificial heart valves can be saved by utilizing a heart valve holder having a plurality of circumferentially spaced legs, to which an artificial heart valve can be releasably held by sutures.
