Abstract: A multilumen catheter comprises separate proximal IV tubes of substantially circular cross-section welded in fluid communication with each of the substantially eliptical-shaped lumens of the catheter. The weld, at the interface between the outer surface of each IV tube and the associated lumen sidewall, is continuous over the interface to provide for an integral fluid sealing connection between the catheter lumen and the IV tube.

Abstract: A process of making a polyurethane condom which comprises providing an organic solvent solution of a polyurethane, a single dipping of a condom form or mold into the polyurethane solution, raising the form from solution and allowing the resultant deposited film to cure at elevated temperatures, thereby forming the condom.

Abstract: Disclosed is an apparatus and method of orienting a cylinder with an oblique end such that the slant of same faces a preferred direction. To this end, a special fixture is used which includes a central axial bore having a cylindrical surface which engages in bearing-like fashion with the oblique-ended cylinder. On opposite sides of the bore, are a magnet for imposing a magnetic field across the bore and across therefrom a dowel pin stop. The magnetic field acts to rotate the oblique-ended cylinder about the common axis of the bore and cylinder into a generally preferred position wherefrom the oblique-ended cylinder can come to its final resting position against the dowel pin stop.

Abstract: The use of oxidized cellulose as a medical lubricant is disclosed wherein oxidized cellulose is employed as a mold release agent or a donning powder in the manufacture of surgical gloves as well as in other applications; medical devices and, particularly, a surgical glove, are provided having finely divided oxidized cellulose powder on the surface in a lubricity imparting coverage.

Abstract: An integral polyurethane winged catheter assembly formed by RF heating individual catheter parts is disclosed.

Abstract: A process of making a polyurethane condom which comprises providing an organic solvent solution of a polyurethane, dipping a condom form or mold into the polyurethane solution, raising the form from solution and allowing the resultant deposited film to cure at elevated temperatures, thereby forming the condom.

Abstract: Physiologic pressure transducers convert an applied pressure (e.g., blood pressure) into an electric signal, which can be displayed by a monitor as a numerical value or continuous waveform. While reusable pressure transducers have been used for a number of years, innovations in solid-state technology have made disposable transducers feasible. In particular, disposal transducers which are impedance matched for use with monitors formally used for reusable transducers are disclosed. The pressure transducer is rugged due to the careful mounting of the transducer diaphragm and integral compensation circuitry. In addition, the geometric configuration of the flow path is uniform such that debubbling of the unit is easy.

Abstract: An antithrombogenic thermoplastic polyurethane product and process for preparing the same which comprises a substrate and at least one layer of a polyurethane alloy complex comprising a thermoplastic polyurethane and completely dispersed therein a preformed complex of an antithrombogenic material ionically bonded with a quaternary ammonium compound.
