Publication number: 20230255846Abstract: An orthopedic limb interface device is disclosed for positioning and retaining a lower portion of the arm of the human body during orthopedic operatory procedures. The device includes a handplate coupled to a sleeve. The sleeve surrounds and grips the arm and is lined with an inflatable bladder. The bladder includes a plurality of inflatable zones, at least one zone having inflation limiting means such that the inflated bladder has a variable inflation profile therealong. The variable inflation profile is configured to increase retention at target areas of the limb, while softly retaining other areas of the limb to avoid limb numbness. Areas of increased retention may engage portions of the arm to improve the grip on the arm for reliable limb distraction.Type: ApplicationFiled: July 14, 2021Publication date: August 17, 2023Inventors: Philip Cormier, Cassandra Rapp, Luis Davila, William D.

Publication number: 20140188039Abstract: Visceral fat may be removed from a subject using a cannula that has an interior cavity and an orifice configured to permit material to enter the cavity. This is accomplished by generating a negative pressure in the cavity so that a portion of the tissue is drawn into the orifice. Fluid is then delivered in pulses, via a conduit, so that the fluid exits the conduit within the cavity and impinges against the portion of the tissue that was drawn into the orifice. The fluid is delivered at a pressure and temperature that causes the visceral fat to soften, liquefy, or gellify, without damaging the subject's internal organs that are in the vicinity of the visceral fat. The visceral fat that has been softened, liquefied, or gellified is then suctioned away.Type: ApplicationFiled: December 28, 2012Publication date: July 3, 2014Applicant: ANDREW TECHNOLOGIES LLCInventors: Mark S.

Publication number: 20070162109Abstract: A modular intraluminal stent graft. The intraluminal stent graft is bifurcated having a primary section and a secondary section extending therefrom. The primary section tapers from a larger diameter at an upstream end to a smaller diameter at a downstream end. The downstream end of the primary section has a pair of independent openings each having an expanded diameter. The secondary section provides a first endoleg having an upstream end that is received through the expanded diameter of one opening of the primary section, and a second endoleg having an upstream end that is received through the second opening of the primary section. The upstream ends of each endoleg, in its expanded state, is larger than the downstream portion of the respective endolegs and expands within the primary section to help assemble the graft in situ. The first and second endolegs also expand within the respective openings each is received within to assemble the stent graft in situ as well.Type: ApplicationFiled: January 11, 2006Publication date: July 12, 2007Inventors: Luis Davila, Frederick Feller
