    摘要: Surgical tools which are used to separate from one another a femoral cup and an acetabular ball in an implanted hip replacement prosthesis. At its distal end, elements of the surgical tool engage the femoral cup and the acetabular cup. When proximal handles of the tool are squeezed toward one another, the engagement elements move away from one another. Thus, a surgeon is able to separate the femoral cup and the acetabular ball from one another without pulling the acetabular cup away from the acetabulum or the femoral cup and/or femoral implant away from the femur, thereby accomplishing the separation without disrupting any bone ingrowth.

    摘要: Methods and compositions are provided for the introduction and washout of vitrifiable concentrations of cryoprotectant in organs and tissues. The methods comprise cooling the organ to below -10°C by perfusion with a solution having a freezing point below -10°C, a temperature from -10 to -40°C, and a tonicity from 1.1 to 2.0 times isotonic, after previous perfusion with said solution for a time insufficient for approximate osmotic equilibration of the organ with the solution. The methods further comprise increasing the concentration of cryoprotectant further at a temperature from -10 to -40°C to prepare the organ or tissue for vitrification. The methods further comprise cooling and vitrifying the organ, rewarming it, and perfusing the organ with a vitrifiable concentration of cryoprotectant that is the same as or less than the concentration used for vitrification, without the addition of an osmotic buffering agent. Rewarming is accomplished either by rapid (>1 °C/min, and preferably -.2-20°C/min) elevation of arterial perfusate temperature from below -20°C to above -15°C during continuous perfusion of the organ or by perfusing the organ with pre-warmed arterial perfusate at >--15°C. Extraordinarily effective multicomponent compositions are also provided for the process, particularly involving a vitrification solution whose warming rate after vitrification can be

    摘要: This invention relates generally to cryopreservation and a method for preventing injury caused by cooling and warming of tissue and for reducing the toxicity of vitrification solutions. The present method achieves reduction or elimination of injury by increasing the tonicity of the medium to greater than isotonic prior to cooling. The method was developed by attempting to simulate without freezing, the events that take place during freezing living cells and/or tissue. A further benefit of the method is that, since the cryopreservation medium is hypertonic, it can be diluted to a more extreme degree in one step once the system is rewarmed, without engendering the degree of cell swelling that would attend the same dilution factor when diluting an isotonic cryopreservation medium.

    摘要: Surprising new combinations of previously-known and novel cryoprotectants are provided that yield superior recovery of function and viability of living systems after exposure to and removal from said systems. These and related combinations are useful for cryopreservation by vitrification, freezing, supercooling, freezing point depression, or cold storage. It is disclosed that, contrary to current opinion, ideal solutions for cryopreservation are those that vitrify 'poorly' (i.e., at higher rather than at lower concentrations). Contrary to expectation, by using relatively 'poor' vitrifiers, the water content of the solution is reduced at the concentration needed to vitrify, but the water availability within the solution is believed to be paradoxically increased, thereby increasing viability. A novel method for understanding and predicting non-specific cryoprotectant toxicity is provided based on a new definition of cryoprotectant 'concentration', which is the number of water molecules per polar group on penetrating cryoprotectants. Compositions are provided that vitrify at relatively high concentrations, yet surprisingly also devitrify slowly on warming. Databases of novel vitrification/devitrification and toxicity data are provided that allow the ordinary practitioner of the art to select specific solutions or obvious solution variants to meet the user's specific cryopreservation needs.
