摘要： A cassette containing a group of sealed cells is used as a means for delivering doses of fluid to be injected into a sterilizing chamber. After the cassette is automatically positioned over a piercing mechanism, the cassette is moved downwardly so that a cell is pierced. Fluid is then forced out of the cell by pneumatic pressure into an injector valve, which opens in a manner which does not adversely affect a vacuum within the chamber.

摘要： A method and apparatus for overpressure protection of a catheter from an indwelling catheter. A method in one embodiment includes injecting an agent into the catheter and relieving overpressures in the catheter during the injecting step. The agent is typically a declotting agent and the obstruction is typically a clot (e.g., blood clot). In one embodiment of the apparatus, a catheter includes a cannula and a first hub and a second hub, each of which are coupled to the cannula. The first hub is for receiving an agent which is placed into the cannula to remove an obstruction, and the second hub includes an overpressure relief valve for relieving an overpressure condition in the cannula. Other embodiments of the invention are also described.

摘要： A composite surgical material comprising a collagen matrix reinforced by a layer of a synthetic bioabsorbable material such as polylactide/polyglycolide or oxidised regenerated cellulose, and wherein oil droplets are dispersed in the collagen matrix. The oil droplets comprise 1% to 75% of the weight of the composite and result in improved leak-proofing of the composite. The composite, in the form of a sheet or a tube, is especially useful as a temporary, fully bioabsorbable prosthesis, for membranes or blood vessels where a highly leak-proof prosthesis is required. The invention also provides a method of making a composite surgical material comprising the steps of: providing a layer of a synthetic bioabsorbable material; providing a dispersion of collagen in an oil-in-water emulsion; coating at least one face of the layer of synthetic bioabsorbable material with the said dispersion; and drying the composite material thus obtained.

摘要： A system for preparing autologous plasma comprises a single use filter unit having two inlets in fluid communication with each other, an outlet, and a filtration membrane selectively permeable to blood plasma separating the inlets from the outlet. Manually operable, single use pumps, preferably syringes, connect to the inlets. A flow path is defined along the membrane between the pumps, whereby, whole blood can be repeatedly exchanged between the two pumps, past the membrane, to cause plasma to flow across the membrane and out of the outlet. A syringe can collect plasma from the outlet. Plasma thus collected can be simultaneously applied with a thrombin solution to a site on the body, thereby forming a fibrin gel.

摘要： A method and apparatus for detecting exposure to an oxidation-type sterilant using a chemical indicator comprising bleachable dye is disclosed. Using the method and apparatus disclosed, a bleachable azo dye is incorporated with an anodized aluminum or chromate conversion coated surface and exposed to an oxidation-type sterilant, such as hydrogen peroxide, and inspected upon completion of the sterilization process for color change. If exposed to sterilant for an appropriate amount of time the bleachable dye changes color thereby indicating adequate sterilization. The surface incorporating bleachable dye may be made to change color after a predetermined number of exposures to a oxidation-type sterilant.

摘要： A system to deliver gas/vapor from solid materials. Specifically, the delivery system for the use of gas or vapor released from a solid material, such as a non-aqueous/solid hydrogen peroxide complex. The system is comprised of a delivery system that is configured to receive a plurality of disks containing the solid material and provide these disks into an injector. The injector heats the disks to produce a gas or vapor that is then provided into a chamber. The sterilization process can be done by gas or vapor alone, or in combination with plasma or ultra violet radiation. In particular, a control system automatically induces the delivery system to provide the injector with a disk and then remove the disk once the injection sequence is complete.

摘要： In a flexible endoscope having a flexible insertion tube comprising a tubular, biocompatible elastomeric outer covering thereabout which encloses an interior space, the improvement according to the present invention comprises a vapor barrier between the outer covering and the interior space. Thus, vapor, such as hydrogen peroxide or other sterilants, passing through the outer covering from an atmosphere thereabout is prevented from entering the interior space by the vapor barrier. Further, the vapor is thus prevented from interacting with substances, such as lubricants, within the interior space to produce agents harmful to the elastomeric covering.
