    摘要: A system for the measurement of a metabolite in a physiological fluid is disclosed which comprises a catheter which includes an internal metabolite sensor downstream from a semipermeable region where dynamic equilibrium is attained between the external metabolite and a higher concentration of the same metabolite contained in an infusate which is flowed through the catheter. The changing metabolite concentration also can open and close a chemical valve to control the codelivery of a drug through the catheter.

    摘要: An implantable access system for infusion of liquids into a body or aspiration of liquid samples from the body. The system includes a septum/manifold (16) and catheter (10) connected thereto, both of specific design. The septum/manifold includes a pair of manifold chambers (24, 25) each closed with a self-sealing septum (20, 22) and each having a first access entry (19) and second access entry (26, 27) (35, 36). The catheter includes a pair of concentric inner and outer tubes (11, 12). The inner tube (11) is collapsible and closed at its distal end. The outer tube (12) closely engages the inner tube and defines a catheter lumen (28) therewith when the inner tube is collapsed by evacuation. The inner and outer tubes are joined together longitudinally over a small portion of the circumference of the inner tube.

    摘要: An implantable, anti-reflux, fluid displacement peritoneovenous shunt system. The system includes a double chambered multi-micro-orifice ascites collection device, a magnetically driven pump, and an anti-reflux, anti-backdiffusion, non-thrombogenic catheter tip, all connected by flexible tubing. The shunt is used to transfer fluid from the peritoneum to the cardiovascular system to prevent accumulation of fluid within the peritoneal cavity. The magnetically operated pump may be of either the reciprocating diaphragm or piston type or it may be a rotary driven bellows displacement pump.

    摘要: A zero net external displacement implantable pump for the transfer of accumulated body fluids, such as transfer of ascites fluid from the peritoneum to the vasculative system. The pump includes a pair of bellows type displacement chambers which are alternately compressed and expanded by action of a pivoted rocker member. The fluid to be transferred is drawn into the chambers on the expansion strokes and expelled on the compression strokes. The rocker member may be operated manually or power driven. Single action and double action pumps are disclosed.

    摘要: An implantable intravascular access system, including an implantable, catheter obturator controller manifold for use with an implantable intravascular catheter. The catheter includes a lumen, having an expanded state and a normal state, an obturator, and an obturator plenum having an inflated state and a contracted state. The lumen can be closed or opened by hydraulically actuating the expansion or contraction of the obturator plenum when the lumen is in its normal state. When the obturator plenum is expanded to its inflated state, the obturator substantially blocks the lumen such that substantially no fluid can pass through the lumen when the lumen is in its normal state. The manifold comprises a housing, a receiving mechanism for receiving the catheter, an actuating mechanism for hydraulically actuating the expansion or contraction of the plenum, and a first entry mechanism for entering the housing.

    摘要: Catheters for long term implantation having polymer surfaces in face-to-face contact which are provided with a thin film coating of a glow discharge plasma polymerized fluorocarbon to prevent adhesion of the contacting surfaces. The polymerized fluorocarbon film, between about 50 and 1000 Angstroms in thickness, is bonded to the substrate material giving a low surface energy without changing its bulk properties. The low surface energy will prevent adhesion of cured polymer surfaces in contact and act as a lubricant. The smooth pinhole-free films will control or prevent diffusion into or out of the bulk material. These biocompatible films provide an alternative use for polymers whose bulk properties are unacceptable but whose surface properties are desirable.

    摘要: The present invention relates to an implantable infusion pump having a refillable infusate reservoir in fluid communication with a delivery site via a flow path. This flow path includes a flow resistance. The infusion pump includes a sensing device(s), positioned relative to the flow path, to provide data regarding a flow rate along the flow path. The infusion pump effects a division of a total flow period into at least a plurality of unit dose periods, each unit dose period effecting delivery of a unit dose of infusate. The cumulative effect of delivering the total number of unit dose periods is the delivery of a desired dose over the total flow period. The present invention permits a reservoir pressure to vary over any portion of total flow period but effects a constant-pressure state over each unit dose cycle.
