A vacuum rig apparatus for introducing a liquid into a space defined by a shaped article, which apparatus comprises a series of interconnected vessels attached through a port to a vacuum line, wherein one of the vessels is adapted to hold the shaped article and the apparatus is tiltable about a point midway along the vessel so that liquid from a reservoir flows into the vessel to surround the shaped article and fill the space therein when a vacuum is applied to the apparatus.

Vacuum rig apparatus

A multi-parameter catheter comprising sensors enveloped in a sheath made from a biphasic material comprising a layer of microporous hydrophobic substance having micropores which are filled with a hydrophilic substance which when hydrated forms a gel and allows the passage of water-bound ions, and an apparatus for introducing the catheter into a patient's blood vessel.

Multi-parameter sensor apparatus

A method for assembling a package for an active medical device which comprises making an opening in a wall of a recess shaped to receive the device, placing a gasket against the wall and about a band mounted through a flat portion of the wall, inserting the band through the opening so the gasket is flush against the wall, installing an outer part about the band to hold the gasket against the wall to form a sterile barrier, and placing a lid over the recess to contain the device within a sterile field.

Method for assembling package for an active medical device

An electrochemical sensor for the determination of the partial pressure of oxygen in a bloodstream comprising a cathode and an anode immersed in an electrolyte contained in a chamber defined by an oxygen gas permeable membrane wherein the insulated portion of each of the conductors forming the cathode and the anode has an additional layer of insulation applied over the original insulation.

Electrochemical sensor

A method for manufacturing an electrochemical sensor which comprises folding into a 'U' shape an exposed, uninsulated portion of an elongate, insulated conductor to form an anode having an exposed, uninsulated distal end surface, positioning the end surface of the anode to face the exposed, uninsulated distal end surface of an elongate insulated conductor forming a cathode, placing the anode and facing cathode within a tube defined by a gas permeable membrane, filling the tube with an electrolyte and sealing the distal end of the tube.

Method for manufacturing an electro chemical sensor

An electrochemical sensor for the determination of the partial pressure of oxygen in a bloodstream comprising a cathode and an anode immersed in an electrolyte contained in a chamber defined by an oxygen gas permeable membrane wherein the conductor forming the anode is folded into a 'U' shape so that the exposed distal end surface thereof faces the distal end surface of the cathode.

A package for an active medical device has a film member pocket recess. The member has a planar flange about the recess and a flat wall with an opening. A lid attaches to the flange. Outer and inner parts of a junction conjugate in the opening to seal and insure sterility. Test means on the inner part test means include a transparent window in a central web to permit optical signal transmission and electrical signals pass through a plurality of spaced apart electrically conductive pins about the web to distally couple the device and test linkage. An inner part band with a brim thereabout fits through the opening so the brim faces the wall. An outer part collar with a rim thereabout conjugates with the band that extends through the opening and the rim abuts in tight facing relation the wall. The brim and band support a resilient gasket for compression between the wall and the brim when threads on the band mate with threads on the collar. An assembly method entails making an opening in the package wall, placing a gasket against the brim, inserting the band through the opening and installing the collar on the band to form a sterile barrier with threads. A test method entails inserting the device in the recess, attaching the device to the junction, applying energy to the connection from outside and receiving modified energy from the device.
