Patent number: 11071635Abstract: Methods and devices are disclosed for joint (e.g., shoulder) arthroplasty, including for reverse joint arthroplasty. In one aspect, there is provided a trial device for determining inclination, offset, and/or version of a prosthetic tray with respect to a prosthetic stem or stemless implant. In another aspect, there is provided a joint (e.g., shoulder) prosthesis, which allows for variable offset, inclination or version or any combination thereof. In another aspect, there is provided a method for setting an offset or inclination angle or a version angle or any combination thereof of a prosthetic tray with respect to a stem or stemless device implanted or to be implanted in a bone of a joint (e.g., shoulder) by matching the corresponding offset or version or inclination or any combination thereof to a trial device.Type: GrantFiled: December 6, 2017Date of Patent: July 27, 2021Assignee: Mayo Foundation for Medical Education and ResearchInventors: John W.

Publication number: 20150320584Abstract: Devices and methods for reducing undesirable noises relating to ostomy bag usage. One embodiment is a sleeve of foam or other sound absorbing material configured to surround substantially all or part of an ostomy bag. The sleeve can have a zippered bag opening to releasably receive the ostomy bag, and a stoma-coupling opening to enable a patient's stoma to be coupled to the ostomy bag. Another embodiment of the sleeve includes a pocket and an active noise cancellation device held in the pocket.Type: ApplicationFiled: August 30, 2013Publication date: November 12, 2015Inventors: Michael E. Kralovec, Ann L. Leland, Stephanie A. Beer, Michael B. Larson

Patent number: 7133084Abstract: Projection lens systems for use with cathode ray tube (CRT) projection televisions are provided which have positive first lens units (U1) and negative second lens units (U2) where the negative second lens units are customized in terms of at least one optical property for at least two of the colors of light produced by the CRTs with which the units are used. The at least one optical property is not spectral transmission, although the second lens units can also be customized for spectral transmission. As illustrated in FIGS. 1B–1F and FIGS. 8B–8F, such customization of a non-transmissive property provides an effective and cost effective approach for improving the color performance of CRT projection lens systems. Constructions for the positive first lens unit which improve image contrast and reduce manufacturing costs are also provided.Type: GrantFiled: December 22, 2005Date of Patent: November 7, 2006Assignee: 3M Innovative Properties CompanyInventors: Jacob Moskovich, Michael B. Larson, Richard J. Wessling

Patent number: 6922295Abstract: A lens assembly adapted to be connected to a CRT and affixed to mounting structure in a projection television cabinet. The lens assembly includes a tubular lens mount having a longitudinal axis and at least a first optical lens element mounted along the longitudinal axis. A tubular focus mount extends along the longitudinal axis and fastening and locking structure connects the lens mount to the focus mount after a focus mount position is obtained. A CRT coupler is formed integrally with the focus mount and includes structure for securing a CRT and for securing the coupler to the mounting structure within the television cabinet. A second optical lens element is mounted to the CRT coupler. A flexible bladder may be used to contain coolant fluid between the CRT and the coupler.Type: GrantFiled: September 19, 2003Date of Patent: July 26, 2005Assignee: 3M Innovative Properties CompanyInventors: Robin S.
