    摘要: An inexpensive device with a disposable cartridge for preparing tissue sealant is disclosed. The device is particularly applicable to stat preparation of autologous tissue sealant. A method of sealing tissue in which the tissue sealant is applied immediately after mixing platelet-rich plasma concentrate (from the device) with a solution of calcium and thrombin is also disclosed. Preparation in the operating room of 5 cc sealant from 50 cc patient blood requires less than 15 minutes and only one simple operator step. There is no risk of tracking error because processing can be done in the operating room. Chemicals added may be limited to anticoagulant (e.g., citrate) and calcium chloride. The disposable cartridge may fit in the palm of the hand and is hermetically sealed to eliminate possible exposure to patient blood and ensure sterility. Adhesive and tensile strengths are comparable or superior to pooled blood fibrin sealants made with precipitation methods.Antifibrinolytic agents (such as aprotinin) are not necessary because the tissue sealant contains high concentrations of natural inhibitors of fibrinolysis from the patient's blood. The tissue sealant also contains patient platelets and additional factors not present in available fibrin sealants that promote wound healing.

    摘要: A device and method for applying a fibrinogen-based tissue sealant to seamlessly connect human or animal tissues or organ parts, to seal wounds, stop bleeding and the like by mixing fibrin or fibrinogen with blood clot-promoting coagulation factors are disclosed. The device includes two cylindrical compartments for separately containing the separate fluid components of the sealant preparation, which are simultaneously displaced from the respective compartments by plungers commonly depressable with the same effective strokes. The plungers may be depressed directly or by a common mechanism (e.g., rack and pinion) for accurately controlling the rate of dispensing fluid. The cylindrical compartments are of the same or different cross-sectional area and are arranged either concentrically or side-by-side. The device further includes structure for merging the two fluid components within an outer sleeve housing an inner needle. The sleeve and needle contain conduits for the flow of the two fluid sealant components as they are expressed from the respective compartments. Also disclosed are a convenient device for filling the two compartments, structure for mixing the fluid components, and for atomizing the effluent sealant fluid stream (i.e., spraying).

    摘要: Bioartificial implants and methods for their manufacture and use are described, particularly bioartificial pancreases. In particular, the implants may be thin sheets which enclose cells, may be completely biocompatible over extended periods of time and may not induce fibrosis. The high-density-cell-containing thin sheets are preferably completely retrievable, and have dimensions allowing maintenance of optimal tissue viability through rapid diffusion of nutrients and oxygen and also allowing rapid changes in the secretion rate of insulin and/or other bioactive agents in response to changing physiology. Implantations of living cells, tissue, drugs, medicines and/or enzymes, contained in the bioartificial implants may be made to treat and/or prevent disease.
