  • Patent number: 7655831
    Abstract: A method and device for shunting fluid from high pressure volumes to low pressure volumes to treat various medical problems caused by an imbalance or malfunction of the regulation of flow between these volumes. Typical problems where the method and device are employed include the treatment of incontinence, treatment of hydrocephalus, treatment of elevated intra-cranial pressure, treatment of elevated intra-ocular pressure and the like. The controlled release of fluid from the high pressure volume is accomplished by inserting a sponge using an insertion device such as an endoscope. The sponge retains and releases fluid in response to a pressure differential between the high and lower pressure volumes. The sponge material may be natural or synthetic and sponges with different porosity and fluid retention are provided to achieve desired flow characteristics.

The interior chamber encloses the interior cavity so the fluid in the interior chamber transfers its thermal energy to the medical fluid in the interior cavity and simultaneously applies pressure to the interior cavity to assist in the delivery rate of the medical fluid through the outlet.

  • Publication number: 20040078021
    Abstract: A method and apparatus are provided by which a fluid may be drawn and packaged within a series of interconnected sterile units. Once filled with the fluid, the connectors joining the sterile units may be sealed and severed to produce a number of separate sterile units. The volume of the separate sterile units may correspond to a single dose of the fluid. The technique allows a fluid to be partitioned into sterile units without exposure to the air or other potential contaminants.

  • Patent number: 6544727
    Abstract: Methods and devices for the removal of psoralens and psoralen photoproducts from blood products are described. The methods include contacting a psoralen- and irradiation-treated blood product with a resin capable of adsorbing psoralens and psoralen photoproducts. The removal process is particularly suitable for use with platelet concentrates and plasma because the process does not have a significant adverse effect on clotting factor function. The methods and devices can be incorporated with apheresis systems and other devices and procedures currently used to process blood products for transfusion.

  • Patent number: 6338904
    Abstract: Disclosed are bio-active coating compositions for polymeric substrates. In particular, a bio-active coating is described which is the reaction product formed by providing a polymer backbone with at least one free isocyanate group, wherein the isocyanate group is pendant from the polymer backbone. There is further provided a hydrophilic, amine-terminated spacer which has at least one amine group at its first and second ends. One of the amine groups of the spacer is reacted with one or more of the isocyanate groups on the polymer backbone in the presence of an optional catalyst agent. A bio-active agent is then covalently bonded onto an unreacted end of the spacer in the presence of a catalyst. Also disclosed are coating compositions for a substrate and methods of preparing same.

  • Patent number: 6267745
    Abstract: A confined air tube is intended to be placed into in-line communication with the transfer tubing of a blood processing system. The confined air tube provides an incremental volume of air, which keeps the transfer tubing from collapsing and sticking together during heat sterilization. After sterilization, the confined air tube accommodates conveyance of a blood component into an associated downstream transfer container. The confined air tube can also receive air vented from the transfer container, so that the blood component can undergo further processing or be stored in an air-depleted environment within the transfer container.
