Abstract: A magnetically operated artificial urethral sphincter for the treatment of total urinary incontinence is presented. The artificial urethral sphincter employs an external magnet to achieve closure of the urethral cuff, a hydraulically operated silicone rubber sphincter cuff. The proposed invention consists of the urethral cuff, a connecting tube, and an elastomeric bellows assembly. The invention is closed by an external magnet placed on the skin over the implanted reservoir assembly. When the external magnet is in place the elastomeric bellows of the reservoir is compressed, and the prosthetic sphincter is closed. Removal of the external magnet from the skin over the implant allows the bellows to expand, thus opening the urethral cuff.

Abstract: A single agent fibrin based hemostatic and tissue adhesive agent comprised of recombinant fibrin monomer, Bovine thrombin, and calcium chloride, which is lyophilized to powder form, and is activated upon blood contact, at the site of tissue injury, producing effective hemostasis and subsequent tissue adhesion.

Abstract: A method and apparatus for manufacturing a circulatory system non-pyrogenic vascular prosthesis comprising a multilaminar tubular member comprising an interior strata, a unitary medial strata and an exterior strata. The interior strata bears a pseudoneointima facilitating lumen surface and the exterior strata bears a stabilization promoter surface. The interior and exterior stratum being separated solely by said unitary medial strata which comprises an exclusionary boundary.

Abstract: An apparatus and a method of use are disclosed which assist in pulsating blood to a patient during cardiopulmonary bypass surgery and assists in weaning a patient after cardiopulmonary bypass surgery by counterpulsating. The apparatus includes a blood pump with a collapsible bladder and a bladder support ring with a plurality of openings to permit the entering of continuous flowing blood, the exiting of a pulsatile blood flow and the release of any air bubbles trapped within the blood supply. The pulsating blood flow is created by the compression of the collapsible bladder when filled with blood. The method consist of connecting the apparatus to the aortic return line of a cardiopulmonary bypass circuitry and to the aortic cannula of the patient. The apparatus is positioned near to the patient to maximize pulsatile output. Compression of the bladder can be synchronized to create the physiologic blood pressure of the patient or to counterpulsate with the patient's heart.
