The invention is further directed to producing a cleaned, disinfected, and devitalized cartilage graft by optionally cleaning and disinfecting the cartilage graft; treating the cartilage graft in a pretreatment solution; treating the cartilage graft in an extracting solution; washing the extracted cartilage graft with a rinsing solution; and subsequently soaking the devitalized cartilage graft in a storage solution. The devitalized cartilage graft is essentially free from metabolically viable and/or reproductively viable cells and the rinsing solution is hypotonic solution or isotonic solution. The present invention is further directed to a cleaned, disinfected, and devitalized cartilage graft and a process for cleaning, disinfecting, and devitalizing cartilage grafts. The invention also relates to a process for repairing a cartilage defect and implantation of a cartilage graft into a human or animal by crafting the cartilage matrix into individual grafts, disinfecting and cleaning the cartilage graft, applying a pretreatment solution to the cartilage graft, removing cellular debris using an extracting solution to produce a devitalized cartilage graft, implanting the cartilage graft into the cartilage defect with or without an insertion device, and sealing the implanted cartilage graft with recipient tissue. The devitalized cartilage graft is optionally recellularized in vitro, in vivo, or in situ with viable cells to render the tissue vital before or after the implantation. The devitalized cartilage graft is also optionally stored between the removing cellular debris and the recellularizing steps.

Convenience kits designed to provide for closed, but selectable liquid transfer from a vial to a variety of IV containers and medical syringes. In particular, a kit for fully enclosing a vial for safety in hazardous drug transfer is disclosed. Generally, the kits contain unitized parts wherever reasonable to limit makes and breaks. Further, pathway determining kits provide selectable pathways for purging connections wish flushing solution where makes and breaks are made between various fluid pathway involved parts such that, when disconnections are made, flush solution is resident at the exposed interface. Also disclosed is a 3-way valve as part of a closed, switchable pathway controlling subsystem by which pathways are selected for reconstituting dry medicine in a vial, displacing a measured dose of liquid from a vial, exchanging gas into the vial for displaced liquid, delivering the measured dose to an IV container.

A suction catheter system including a durable transparent pouch used to hold irrigating solution and a catheter in a contaminant-free environment between uses.

A convenience kit which provides a basic configuration for use in measuring, filling and dispensing medication and flush solutions to IV sets and patient catheters through needleless connectors while improving safety and efficacy by requiring fewer post-sterilization makes and breaks compared to conventional filling and dispensing methods. Further, the kit improves flush compliance by facilitating dispensing of flush solutions and decreases likelihood of infections by providing for flushing of patient lines and catheter connecting fittings without line breaks. Convenience of operation is provided by a two-syringe assembly which is operable by a single hand for selective dispensing accomplished from either of the two syringes while obstructing flow from the other syringe. The kit comprises a clip for stabilizing the two syringe assembly.

Two convenience kits are disclosed. A first convenience kit provides a basic configuration for use in measuring, filling and dispensing medication and flush solutions to IV sets and patient catheters through needleless connectors while improving safety and efficacy by requiring fewer post-sterilization makes and breaks compared to conventional filling and dispensing methods. A second convenience kit which, being a companion to the first convenience kit, provides safety in access to a vial. Methods of use of both kits improve flush compliance by facilitating dispensing of flush solutions and decreases likelihood of infections by providing for flushing of connecting sites while reducing numbers of breaks required for associated medical procedures.

In a method for sclerotherapy for treating varicose veins, a flushing solution, such as sterile saline solution, is initially injected into the vein or vessel being treated. The flushing solution displaces or flushes out blood from the treatment site of the vessel. A sclerosing agent is then injected into the treatment site. The displacement of blood before introduction of the sclerosing agent reduces complications. A syringe assembly useful for performing the method has first and second reservoirs sealed off from each by an end cap. The end cap is removed just before use. A needle is attached and is connected to both reservoirs. Flushing solution is delivered from the first reservoir followed by sclerosing solution delivered from the second reservoir, without removing the needle from the vessel.
