Abstract: An organ preservation system having; an organ chamber with a perfusate reservoir, a pump arranged to circulate perfusate, from the reservoir and passes the perfusate through a dialysis filter, oxygenator, and temperature and pressure sensors prior to entering the chamber where an organ is perfused. The organ rests on the platform such that perfusate leaving the organ flows into the perfusate reservoir. The dialysis filter having permeable tubes which allow perfusate constituents to be exchanged with dialysate flowing through the dialysis filter. The dialysate pass through an ion exchange resin removing selected constituents or waste products from the dialysate by absorption by the ion exchange resin. Following waste absorption, the dialysate is recycled to the dialyzer to again remove waste. Removing waste products from the perfusate by dialysis followed by removal of the waste products from the dialysate with the exchange resin, enables dialysate reuse for extended duration.

Abstract: A cannula connects an organ with a perfusion system that monitors, treats, sustains and/or restores the viability of the organ and/or that transports and/or stores the organ. At least part of a cannula may be made of a soft elastomer to help avoid damage to the organ. In embodiments, the cannula includes a top portion, a bottom portion, a sealing ring and two compression straps. In embodiments, the cannula includes a top portion and a flexible bottom portion that may be attached to the top portion. In embodiments, part of the cannula is inserted directly into an artery and a suture is used to tie the artery in place. Also, the cannula may include an attachment feature that can be used to connect the cannula to an organ platform or chair. Various features of the cannula may allow a visual check for and venting of air bubbles in the cannula.

Abstract: A method for controlling a pump for delivery of liquid to an organ over a series of fixed-length time intervals f, each interval f comprising a time t1 and a time t2 wherein t1+t2 equals the length of interval f. The method comprises allowing output pressure of the pump to decrease over time t1, increasing output pressure of the pump over time t2, comparing achieved pump output pressure to a predetermined pressure at about the end of interval f, and at least one of (i) adjusting t1 and t2 if necessary so the predetermined pressure is approximated by the output pressure at the end of the next interval f, and (ii) adjusting a rate of change of the output pressure during at least one of t1 and t2 if necessary so the predetermined pressure is approximated by the output pressure at the end of the next interval f.

Abstract: A hand therapy system having a glove including a compressible substance coupled to a palm portion providing resistance to the closing motion of the hand and one or more elastic members spanning from the compressible substance to respective ones of one or more finger portions, the one or more elastic members provide resistance to the opening of the hand. Also included are a means for providing a signal proportional to the movement of the digits of the hand while opening and closing and a means for providing a signal proportional to the pressure applied by one or more of the digits of the hand on the compressible substance. A controller is coupled to the means for providing a signal proportional to the movement and the means for providing a signal proportional to the pressure and also a computer coupled to the controller via a computer link.

Abstract: An exercise and therapy hand device consists of a glove for receiving a hand. The glove includes a palm portion, one or more finger portions for receiving a finger, a back portion, and a compressible substance that is coupled to the palm portion. Also included in the glove are one or more elastic members that span from the compressible substance to respective ones of the one or more finger portions. The compressible substance exercises the muscles of the hand that control the closing of the hand, while the one or more elastic members exercise the muscles of the hand that control the opening of the hand.

Abstract: A filament assembly is disclosed for providing an electron beam to an ion source volume to ionize molecules or particles in the ion source volume. The filament assembly includes an electron lens which accelerates electrons emitted by the filament and focuses the electrons into a beam.
