Publication number: 20080077178Abstract: A device is proposed for inserting hemostatic material through a tissue channel and against the wall of a blood vessel of a patient, wherein the blood vessel wall has a puncture therein adjacent the tissue channel. The device includes a charge of hemostatic material and a hollow sheath adapted to pass through the tissue channel, the sheath having a cross sectional profile larger than the puncture. The device places the hemostatic material in the hollow sheath and advances the hemostatic material through the sheath to the vessel wall around the puncture.Type: ApplicationFiled: March 19, 2007Publication date: March 27, 2008Applicant: Datascope Investment Corp.Inventors: Ernst Janzen, Gunter Ruttgers, Lawrence Saper, Sid Wolvek, Irma Wolvek

Patent number: 5090410Abstract: A bandage for attaching a sensor to a part of the human body while protecting the sensor against contamination and permitting its reuse in which the sensor is located within a flexible transparent sleeve which is fastened to the adhesive inner surface of the bandage, the parts of the bandage inner adhesive surface outside of the sleeve thereafter being fastened to the body. In the preferred embodiment the probe is an oximeter probe with a light emitter and a light detector. Apertures are provided in the bandage to view the positioning of the oximeter components.Type: GrantFiled: June 28, 1989Date of Patent: February 25, 1992Assignee: Datascope Investment Corp.Inventors: Lawrence Saper, Bruce L.

Patent number: 4994018Abstract: A dual tubular member intra-aortic balloon assembly (1) has an inflatable balloon (4) bonded, at its proximal end, to an outer tubular member (2), and at its distal end, to an inner tubular member (3). The inner tubular member is composed of metal, being axially rigid yet bendable along its length. A flexible forwardly projecting extension (12) is attached to the inner tubular member for guiding the relatively stiff balloon assembly over a guide wire (9) through a tortuous arterial path, without causing buckling or misplacement of the guide wire. The junction between the inner tubular member and the flexible tubular member extension is embedded within a flexible tip (10) which reinforces the juncture to prevent balloon failure due to bending stress at the same time, enables a tighter balloon wrapping by eliminating the enlarged junction of the inner tubular member and flexible tip within the balloon membrane.Type: GrantFiled: May 31, 1989Date of Patent: February 19, 1991Assignee: Datascope CorporationInventor: Lawrence Saper
