Methods and apparatuses for exsanguination or replacement of blood in a tissue are presented. These methods and apparatuses may be used to preserve and prepare an organ or other tissue for transplantation while increasing the likelihood of a successful procedure. Improved methods are also provided for the splitting of organs and other tissues.
The invention relates to the field of organ and biological tissue preservation. In particular, the invention relates to machine perfusion or cold storage solutions for the preservation of organs and biological tissues for implant and/or transplant. The preservation solution includes a prostaglandin having vasodilatory, membrane stabilizing, platelet aggregation prevention upon reperfusion, and complement activation inhibitory properties, a nitric oxide donor, a glutathione-forming agent, L-arginine, and ~-ketoglutarate.

Apparatus and method for perfusion and determining the viability of an organ
An organ perfusion apparatus and method monitor, sustain and/or restore viability of organs and preserve organs for storage and/or transport. Other apparatus include an organ transporter, an organ cassette and an organ diagnostic device. The method includes perfusing the organ at hypothermic and/or normothermic temperatures, preferably after hypothermic organ flushing for organ transport and/or storage. The method can be practiced with prior or subsequent static or perfusion hypothermic exposure of the organ. During the period in which the organ is preserved and/or maintained, the organ may be additionally be perfused to obtain data regarding the fluid and/or organ. The data may then be used to ultimately provide information regarding the perfusion efficacy and allow for altering of the perfusion parameters.

The method includes perfusing the organ at hypothermic and/or normothermic temperatures, preferably after hypothermic organ flushing for organ transport and/or storage. The method can be practiced with prior or subsequent static or perfusion hypothermic exposure of the organ. Organ viability is restored by restoring high energy nucleotide (e.g., ATP) levels by perfusing the organ with a medical fluid, such as an oxygenated cross-linked hemoglobin-based bicarbonate medical fluid, at normothermic temperatures. During the period in which the organ is preserved and/or maintained, various drug research and development may be performed on and/or with the organ. The organ may be perfused with a fluid containing a substance such as a test substance to obtain data regarding the organ, the substance and an interaction of the substance and the organ. The data may then be used to ultimately provide information regarding the drugs efficacy in support of regulatory filings for new drugs.
A method for controlling a pump for delivery of liquid to an organ over a series of fixed-length time intervals ~, each interval ~ comprising a time t 1 1 and a time t 2wherein t 1 + t 2 equals the length of interval ~. The method comprises allowing output pressure of the pump to decrease over time t 1 91 increasing output pressure of the pump over time t 2 , comparing achieved pump output pressure to a predetermined pressure at about the end of interval ~, and at least one of (i) adjusting t 1and t 2 if necessary so the predetermined pressure is approximated by the output pressure at the end of the next interval ~, and (ii) adjusting a rate of change of the output pressure during at least one of t 1 and t 2 if necessary so the predetermined pressure is approximated by the output pressure at the end of the next interval ~.

The invention is targeted at the process of separating gas, such as air, from a liquid path. Specifically, the invention provides a means to remove gas from a dynamic liquid path, manage the removed gas and liquid path. The invention provides a means to remove gas from a dynamic liquid path using the buoyant property of gas in a less buoyant liquid, having ingress and egress ports for liquid and gas flow, and separate points of egress for liquid and trapped gas and integral liquid channels.
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.
