Patent number: 7473261Abstract: An external incontinence clamp for stopping involuntary voiding of urine is provided. The clamp includes a first rigid member having opposed ends, each end defining a passage extending therethrough, a second rigid member having opposed ends, each end defining a passage extending therethrough, and two pins of generally u-shape. The pins are adapted to be received by the passages defined by the ends of the first rigid member and of the second rigid member so as to secure the first rigid member in a spaced and generally parallel relationship to the second rigid member. The penis is positioned between the first and second members so that the underside of the penis is in contact with the second member and the top surface of the penis is in contact with the first member, thereby stopping involuntary voiding of urine.Type: GrantFiled: September 21, 2005Date of Patent: January 6, 2009Inventor: Henry Rennich

Publication number: 20080319328Abstract: A femoral compression device (1) for compressive bearing against the femoral artery of a patient, comprising a base plate (2), an inflatable air cushion (4), and an electronic manometer (8) connected to the inflatable air cushion for measurement of the current pressure difference between the pressure prevailing inside the inflatable air cushion and the ambient air pressure. The femoral compression device can further comprise a mechanical device (11; 46) which prevents an air opening leading to the inflatable air cushion from being closed before the manometer is zeroed.Type: ApplicationFiled: June 22, 2007Publication date: December 25, 2008Inventors: Dan AKERFELDT, Leif Smith, Marie Lindstrom, Tobias Adenmark

Publication number: 20080319473Abstract: A device for applying pressure to a pocket and for preventing hematoma after surgically implanting a medical device in the pocket. The device may have first and second portions for contacting the front and back sides of a patient, respectively, and a device for applying pressure to the pocket. The device may have cushions or padding for comfort. The pressure may be adjustable. The device allows a patient to ambulate with constant pressure on the pocket. The device may have a clamp, hinge, clasp, clip, spring, piston, pneumatic or inflatable device, band or any other device that applies pressure to the pocket.Type: ApplicationFiled: June 20, 2007Publication date: December 25, 2008Inventor: Murray Rosenbaum

Publication number: 20080300518Abstract: A device, method and system are disclosed for assisting a rescuer attempting to resuscitate a patient in need of resuscitation. A CPR assist device is provided that includes a first indication of a first surface of the CPR assist device to place in contact with a patient. The CPR assist device further includes a second indication of a second surface of the CPR assist device to place in contact with a patient. In one embodiment, the CPR assist device is adapted to provide indicia to a rescuer that provide instructions to assist the rescuer to resuscitate the patient. In another embodiment, the CPR assist device is adapted to initiate or adjust instructions and/or therapy based on whether the first surface or the second surface of the CPR assist device is placed in contact with the chest region of a patient in need of resuscitation.Type: ApplicationFiled: June 2, 2008Publication date: December 4, 2008Inventor: C. J. Bowes

Publication number: 20080281240Abstract: Pneumatic compression devices and methods for using the same are disclosed. A pneumatic compression device may include a compression pump, a fill/exhaust valve, a transducer, a plurality of cell valves, and a controller. The compression pump may output a pressurized fluid via an output. The fill/exhaust valve may connect one or more cell valves to the compression pump when in an open state and to the atmosphere when in a closed state. The transducer may sense a pressure level. Each cell valve may correspond to a cell and may connect the fill/exhaust valve to the corresponding cell when in an open state. The controller may determine a state (either open or closed) for each of the fill/exhaust valve and the plurality of cell valves based on at least the pressure level sensed by the transducer.Type: ApplicationFiled: May 8, 2007Publication date: November 13, 2008Applicant: WRIGHT LINEAR PUMPInventors: Carol Lynn Wright, James Gasbarro

Patent number: 7445625Abstract: The invention provides an air cushion unit (4) for use in conjunction with a compression device for stopping bleeding from puncture wounds. The air cushion unit (4) comprises a base plate (5), an inflatable air cushion (6), which is attached to the base plate (5), and an internal telescopic guide (7), connecting the base plate (5) with the top of the air cushion (6). Throughout the pressurizing of the inflatable air cushion (6), the length of the telescopic guide (7) corresponds to the degree of expansion of the air cushion (6), thereby providing an internal support for the air cushion unit (4), which eliminates undesired, irregular movements of the air cushion (6).Type: GrantFiled: February 2, 2005Date of Patent: November 4, 2008Assignee: Radi Medical Systems ABInventor: Dan Åkerfeldt

Patent number: 7435232Abstract: Methods and apparatus for non-invasively assessing physiological hard of soft tissue of human and other species are described. In a preferred embodiment, tissue is vibrationally stimulated in vivo through a frequency spectrum. The tissue reacts against the stimulus and the reaction is preferably measured and recorded. Based on analytical algorithms or comparisons with previously taken measurements, changes within the tissue can be detected and used for diagnostic purposes. Further embodiments describe the usage of the device and methods for in vivo intra-operative and post-operative implant evaluations and as a therapeutic tool.Type: GrantFiled: September 7, 2004Date of Patent: October 14, 2008Assignee: William Marsh Rice UniversityInventor: Michael Liebschner
