20090012629 | COMPOSITIONS AND METHODS FOR TISSUE REPAIR - Implants for repairing tissue defects, such as cartilage tissue defects, and methods of their preparation and use are disclosed. A mold of a tissue defect is prepared by pressing upon the defect a substrate having shape memory, such as aluminum foil. The mold, which has contours substantially conforming to those of the defect, is removed from the defect, and tissue particles are added to the mold ex vivo. A biological carrier such as biocompatible glue is also added to the mold. The combination of tissue particles and the biological carrier thereby form an implant, which retains its shape after separation from the mold. The implant can be transferred to the tissue defect, with contours of the mold matching corresponding contours of the defect. | 01-08-2009 |
20090054906 | MEDICAL DEVICE AND METHOD FOR DELIVERING AN IMPLANT TO AN ANATOMICAL SITE - A medical device and method for providing an implant to an anatomical site are disclosed. The medical device generally comprises a sleeve having first and second ends, a cutting frame coupled to the second end, and a rod received in an inner bore of the sleeve. The cutting frame defines a guide configured to direct a cutting tool for reciprocal motion along a cutting plane. When the implant is positioned within the inner bore, the rod and sleeve are used to gauge a depth of the anatomical site and to advance a portion of the implant beyond the cutting plane. The implant may then be cut to an appropriate size to fit the anatomical site. | 02-26-2009 |

20100140521 | STEMLESS BALL VALVE - A stemless ball valve comprising two flanges and a ball with a channel, two axis pins and two travel pins. One end of each axis and travel pin is fixedly attached to the ball, and the other end of each axis pin is lodged into a notch in the first or second flange such that the axis pin is allowed to rotate in the notch. The guide sleeve comprises two channels, and one end of each travel pin is situated within one of the two channels in the guide sleeve. An outer magnetic cartridge causes the inner magnetic cartridge and guide sleeve to rotate, and when the guide sleeve rotates, the travel pins move up and down within the channels in the guide sleeve. The movement of the travel pins within the channels in the guide sleeve causes the ball to rotate, thereby opening and closing the ball valve. | 06-10-2010 |
20100325785 | AUTOMATICALLY FLUSHING TOILET - An automatically flushing toilet in which an extension arm is attached to a horizontal bar to which the toilet seat is attached. When the toilet seat is raised, one end of the extension arm moves downward, causing a rod on the end of the inner tube of a telescoping member located primarily inside the tank compartment of the toilet to move so that it is positioned atop a pivoting member located inside a cut-out on the same end of the extension arm. When the toilet seat is then closed, the one end of the extension arm moves upward, pushing the pivoting member against the rod and causing the rod to force the inner tube of the telescoping member upward. The inner tube is pivotally connected to a trip lever, which causes the toilet to flush. | 12-30-2010 |
20110180739 | STEMLESS BALL VALVE - A stemless ball valve comprising: a right flange; left flange; ball with an axis pin and two travel pins; ball seal on either side of the ball; guide sleeve with inner walls comprising two channels; cartridge guide holder; inner magnetic cartridge; and outer magnetic cartridge. The ball is situated inside of the guide sleeve, and a travel pin is located in each of the two channels. The guide sleeve is situated inside of the cartridge guide holder, which is located adjacent to and outside of the inner magnetic cartridge and secured to the inner magnetic cartridge such that when the inner magnetic cartridge rotates, the cartridge guide holder also rotates. The cartridge guide holder is secured to the guide sleeve such that when the cartridge guide holder rotates, the travel pins move within the channels in the inner walls of the guide sleeve, thereby causing the ball to rotate. | 07-28-2011 |
20120187319 | PLANETARY GEAR VALVE - A stemless ball valve comprising a first flange, second flange, ball, inner magnetic cartridge, outer magnetic cartridge, and planetary gear assembly. The inner magnetic cartridge is situated inside of the outer magnetic cartridge, and the inner and outer magnetic cartridges actuate the valve. The planetary gear assembly is situated between the inner magnetic cartridge and the ball. The planetary gear assembly comprises one or more planetary gear phases, each planetary gear phase comprising a step-down gear. Each planetary gear phase comprises one or more planetary gears that engage with the inner teeth of the outer ring of the planetary gear assembly and with a step-down gear. | 07-26-2012 |
20120319019 | LEAK-FREE RECIPROCATING STEMMED VALVE - A valve assembly comprising an adapter plate assembly comprising an adapter plate, a bonnet with a center and a threaded shaft extending through the center of the bonnet; an actuation assembly comprising an outer enclosure and an outer magnetic cartridge that is magnetically coupled to an inner magnetic cartridge; and an inner valve assembly comprising an inner enclosure and a planetary gear subassembly comprising one or more planetary gears. | 12-20-2012 |
