  • Publication number: 20030216691
    Abstract: An apparatus has two principal components: a pressure driver, typically a gas filled cartridge, canister, container or the like, that is activated by opening of a membrane, typically a metal foil by puncturing or rupturing, and a holder, that maintains the pressure driver in an air tight chamber. When the cartridge is opened, the pressurized gas exits the cartridge and enters the air tight chamber, causing it to expand. This expansion creates pressure on the portion of the apparatus holding a fluid filled container, and ultimately forces fluid out from the container, typically into tubing, so that the fluid reaches a patient. A simple valving device, typically in a handpiece, and typically proximate the surgical site, can be used at the end of the tubing to regulate the fluid flow into the patient. Systems employing this apparatus are also disclosed, as are method of use for the aforementioned apparatus and systems.

  • Publication number: 20010021822
    Abstract: An osmotic delivery system has a membrane plug retention mechanism which can also be used to control the delivery rate of a beneficial agent from the osmotic delivery system. The osmotic delivery device includes an implant capsule containing a beneficial agent and an osmotic agent. Holes are formed along a side wall of the implant capsule at an open end of the capsule. When the membrane plug is inserted into the open end of the capsule the membrane material swells into the holes in the capsule side wall creating a large frictional force which prevents expulsion of the membrane plug. A beneficial agent delivery rate of the osmotic delivery system is controllable by varying the size and number of the holes to change the amount of exposed surface area of the membrane plug. An increase in the surface area of the membrane plug exposed to the exterior environment causes a corresponding increase in the liquid permeation rate of the membrane and thus, increases the beneficial agent delivery rate.

The needle stop structure prevents a needle that has accessed the fill chamber from penetrating the fluid flow structure that extends from the fill chamber. In one embodiment of the invention, the needle stop structure overhangs the port thereby preventing a needle from entering the port. In a further embodiment of the invention the needle stop structure includes a nozzle-like annular collar which extends from the port into the fill chamber. In another embodiment of the invention, the needle stop structure includes a nozzle-like annular collar that extends from the port into the fluid flow structure. In yet another embodiment of the invention, the needle stop structure includes a cup-shaped structure that extends from the port into the fluid flow structure and has an opening in the fluid flow structure.
