Abstract: A balloon sleeve is provided for a balloon catheter, and the balloon catheter itself with the balloon sleeve provided wherein a substantially smaller front end cross-section is presented for insertion into a patient. The balloon sleeve has a thermoplastic film positioned adjacent each end thereof. However, one is on the internal surface and one on the outer surface enabling mounting the sleeve in a reverse lap fashion wherein the entire balloon body is so reverse lapped when mounted. The mounting eliminates separate objects for securing the balloon sleeve. Nevertheless, the manner of mounting causes the inflated balloon to flow over and protect a patient from the catheter end.

Abstract: A soft, low modulus, non-crystalline segmented polyurethane characterized by a 100% modulus less than about 250 psi, initial tensile set less than about 30% and tensile strength of about 3500 to 6500 psi obtained by balancing the percent hard segment and the degree of cross-linking within the ranges 14 to 25% hard segment and 5,000 to 30,000 molecular weight per cross-link in a segmented polyurethane; and a flexible glove for use by surgeons and others which is easily donned and comfortable on the hand, wherein the glove forming material consists essentially of the aforesaid polyurethane.

Abstract: A powder coating process for producing soft, flexible polyurethane films particularly in the form of a surgical glove, wherein low melting crystalline prepolymer particles are powder coated and cured to an essentially non-crystalline film.

Abstract: Low energy-curable coatings compositions of (1) an epoxide, (2) a polyisocyanate and as a catalyst and initiator a mixture of (3) a stannous salt and (4) a liquid polycarboxylic acid produced by the reaction of a polycaprolactone and an intramolecular polycarboxylic acid anhydride.
