Drug administration method

InactiveUS7427607B2Reduce weightPrevention of the adhesion of an organBiocidePowder deliveryBiopolymerDrug administration
A method of administering a drug whereby a fine drug powder can be accurately administered to a target site (in particular, a target site in the body cavity) via fluidization and spraying with a gas by using a micro tube. Concerning the administration mode, in particular, the drug alone or a biopolymer is administered or the biopolymer is employed as a carrier in the above method. More specifically speaking, a method of administering a fine drug powder which comprises finely milling one or more types fine particles of the drug and / or the biopolymer, blending them each other, fluidizing the blend with a gas, then transporting the fluidized matter in a micro tube by the gas stream and spraying the fine drug powder from the tip of the micro tube toward the target site. Further, an administration method which comprises concentrically providing a capillary tube in the micro tube, supplying an aqueous solution of the drug and / or the biopolymer from the capillary tube into the gas stream and then mixing it with other fine particles of the drug and / or the biopolymer under transportation by the gas.

Surgical access apparatus and method

A surgical access device includes a single valve that forms a seal with the body wall and provides an access charnel into a body cavity. The valve has properties for creating a zero seal in the absence of an instrument as well as an instrument seal with instruments having a full range of instrument diameter. The valve can include a gel and preferably an ultragel comprised of an elastomer and an oil providing elongation greater than 1000 percent and durometer less than 5 Shore A. The shore valve can be used as a hand port where the instrument comprises the arm of a surgeon, thereby providing hand access into the cavity. A method for making the surgical access device includes the combining or a gelling agent with an oil, preferably in a molding process. A method for using the device includes steps for creating an opening with the instrument. In a particular process, an organ can be removed from the body cavity through the single valve to create an organ seal while the organ is addressed externally of the body cavity. The valve and method are particularly adapted for laparoscopic surgery wherein the abdominal cavity is insufflated with a gas thereby requiring the zero seal, the instrument seal, and the organ seal in various procedures.

Apparatus and method for delivering and deploying an expandable body member in a uterine cavity

An apparatus and method delivers an expandable body member into a uterine cavity of a uterus through a cervical opening and deploys the expandable body member in the uterine cavity. The expandable body member in a compressed state is inserted into the uterine cavity. A fluid is provided to the uterine cavity at a pressure sufficient to inflate the uterine cavity. The expandable body member expands from the compressed state to the expanded state. After expansion of the expandable body member and inflation of the uterine cavity, the fluid pressure is relieved thereby collapsing the uterine cavity about the expandable body member in the expanded state such that an endometrial layer of the uterus and a surface of the expandable body member substantially contact each other in a facially opposing relationship maximizing contact therebetween. The apparatus which performs the method includes an elongated tubular member having the expandable body member connected to a distal portion of the elongated tubular member and a fluid-providing device connected to a proximal portion of the elongated tubular member.
