The filter needle enables the medicament liquid to be injected into the patient without exchanging the syringe. The filter needle o is integrally formed of medical silicone to enable easy assembly and safety during use.

A filter member may be removably mounted to, or formed integrally with, the mounting member to filters fluid when filling the syringe to thereby remove particular material, impurities or the like. Alternatively, a filter material may be provided in the syringe adapter. In addition, or alternatively, a filling needle is provided which is removably mountable to the syringe adapter and may prevent bending or burring of the retractable needle.

  • Patent number: 8172929
    Abstract: Various embodiments of the present invention are directed to limiting a presence of air bubbles in fluidic media in a reservoir. Air passages may allow air to escape from fluidic media in a reservoir. Membranes may allow for trapping air bubbles in fluidic media before fluidic media enters a reservoir. A membrane may allow air to flow from a first reservoir containing fluidic media to a second reservoir while plunger heads within each of the reservoirs are moved within the reservoirs. An inner reservoir with a membrane may be moveable within an outer reservoir to allow air to move from the outer reservoir to the inner reservoir. An inner reservoir containing pressurized gas may allow fluidic media to be transferred to an outer reservoir.

    Abstract: A system in accordance with embodiments of the present invention includes a cannula interconnected to a collection vessel by a flexible conduit. The collection vessel can comprise one or more syringe bodies. The syringe bodies are provided with tissue removed from a body using the cannula by a tissue transfer channel. As a result, multiple syringe bodies can be loaded with tissue, without requiring manual handling of that tissue. Alternatively or in addition, a collection bag can be provided for receiving tissue removed from a body using a cannula. The tissue collection bag can include a filter. A collection vessel comprising a collection bag can be used in combination with a collection vessel comprising one or more syringe bodies.

  • Patent number: 8057427
    Abstract: A drug delivery system includes an automatic injector that can deliver a small, precise amount of a therapeutic agent. The automatic injector includes a chamber for containing a liquid component and a thin porous member that carries thereon and/or therein the small, precise amount of therapeutic agent. Upon activation of the automatic injector, a flow path opens from the chamber through the porous member, enabling the liquid component to rapidly mix with the therapeutic agent before being injected.

  • Patent number: 8043267
    Abstract: The prefilled syringe filled with a drug in advance, leaking of liquid from the cap is prevented, gas barrier properties are given to the whole of the barrel filled with the drug and the shoulder section so that degradation of the drug is prevented, permeation of microbial contaminants is prevented to a high extent, and efficiency of packing as a compact container can be increased. The prefilled syringe includes a guard-shaped extension projecting from the outer periphery of a shoulder section of the syringe barrel on the nozzle side, and a range from a part where a gasket of the plunger is positioned on the outer surface of the syringe barrel filled with the drug to the guard-shaped extension is covered with barrier packaging.

    Abstract: Medical device assemblies capable of aspirating liquid into a syringe barrel or other medical devices while evacuating any air from the syringe are described. An exemplary medical device includes a syringe barrel, plunger rod and stopper assembly having an air permeable and liquid impermeable porous portion and structure for forming a vacuum within either the stopper or the plunger rod. Described is a medical device including a syringe barrel, plunger rod and stopper assembly having an air permeable and liquid impermeable porous portion and structure for forming a vacuum within chamber between the stopper and plunger rod wherein the plunger rod includes a sealing edge and is moveable relative to the stopper. Exemplary medical devices may include a vent for allowing air that permeates through the porous portion to escape to atmosphere. Methods for aspirating a syringe barrel with a liquid are also provided.

  • Patent number: 8002751
    Abstract: A single in-line filter hollow needle has an outer wall, a proximal end, a distal end with a pointed tip and a central opening between the ends for communicating fluids therethrough. The proximal end is secured to a luer lock for removable connection to a syringe. A filter is located in the central opening proximate to the tip. The outer wall of the needle has a frangible deformation proximate to the filter and remote from the end of the needle whereby the needle may be broken to expose a fresh point after fluid is aspirated through the needle to the syringe is filtered.

  • Patent number: 7934603
    Abstract: The delivery system of the present invention is comprised of at least two chambers which store, individually, an activated blood component and an inactivated blood component. The first chamber comprises an activating agent and a filter which may be one in the same thus allowing the formed clot to be triturated thereby isolating the thrombin from the clot. The second chamber stores the inactivated blood component that when mixed with thrombin will produce a gel. The first or second chamber may further contain agents which are desired to be delivered to a specific site. The unique design of the delivery system allows for ease in operation of combining two agents at a specific time and place.

  • Publication number: 20110021999
    Abstract: A flow delivery system includes a syringe and a needle and/or a catheter that delivers an aqueous solution of a material, e.g., a biomaterial alone or mixed with a fluid lubricant, into a body. A filter located within the body of the syringe includes a plurality of openings each of a predetermined size. As the solution travels through the syringe, the solution encounters the filter openings which break up or downsize any biomaterial particles larger than the size of the openings. Also, the filter openings allow any particles of the biomaterial originally smaller than the size of the openings to pass without any downsizing. The size of the filter openings is selected as a function of the size of the opening in the needle and/or catheter. The downsized particles then pass with any other non-downsized particles in a relatively unobstructed manner into the body through the needle and/or catheter.
