Patent number: 9569566Abstract: A description of a device and method of use are provided for a containment chamber, accompanying sensing and monitoring instrumentation, and method of creation of a physical force wave that would be capable of mimicking physiologic waves such as pulse pressure, muscle contraction, peristalsis, acoustic waves and other desired waves to be studied. This device allows for the use of various biologic or biologically comparable fluids—alone or in combination—that would allow for the analysis of the passage of these waves through these media. Singularly, this device also allows for the manipulation of the external constraints that mimic the containment of that media in vivo. This allows for the analysis of the effects on the nature of the wave, its reflections, potential augmentation or dampening that occur in conjunction with various selected external and internal (baffle) constraints that mimic those found in nature or in therapeutic interventions.Type: GrantFiled: December 12, 2012Date of Patent: February 14, 2017Assignee: Zam Research LLCInventors: David S.

Patent number: 8292895Abstract: A system for removing osteal cement and prosthetic joint components in connection with a prosthetic joint revision includes a controller connected to and controlling operation of a transducer, such as a surgical saw or drill. A tool mounted on the transducer is adapted for engaging the prosthetic joint cement mantel and melting an engagement portion of same. The cement in the engagement portion is resolidified with the tool tip embedded therein. The tool thus bonds to the cement mantel, and is used for vibrating softening and breaking up same when operation of the transducer resumes. An osteal cement and prosthetic device removal method includes the steps of melting an engagement portion of the osteal cement mantel, bonding a transducer-mounted tool to the cement mantel by resolidifying the cement engagement portion and reactivating the transducer for vibrating, softening and breaking up the cement mantel whereby it can be removed from the patient.Type: GrantFiled: February 5, 2008Date of Patent: October 23, 2012Inventor: Stephen K.

Patent number: 7976519Abstract: A tissue closure treatment system and method are provided with an external patient interface. A first fluid transfer component (FTC1) can be placed directly on a suture line for transferring fluid exuded therethrough. An underdrape is placed over FTC1 and includes a slot exposing a portion of same. A second fluid transfer component (FTC2) is placed over the underdrape slot in communication with FTC1. Negative pressure is applied to FTC2 through a connecting fluid transfer component (FTC3). The tissue closure method includes a manual operating mode using a manual suction device with an automatic shut off for discontinuing suction when a predetermined volume of fluid has been drained. An automatic operating mode utilizes a microprocessor, which can be preprogrammed to respond to various patient and operating conditions. The method proceeds through several phases with different components in place and different patient interface functions occurring in each.Type: GrantFiled: October 3, 2005Date of Patent: July 12, 2011Assignee: KCI Licensing, Inc.Inventors: Stephen K.
