Title: Stents and stent-grafts having enhanced hoop strength and methods of making the same
Inventor: PINCHUK LEONARD
IPC: A61F2/90
Filed: 1997-03-13
Abstract: Stents are coated with a polymer such that the polymeric coating binds the crossover points of the wires, or, in the case of a zig-zag stent, binds adjacent zig-zags of wires without occluding the interstices of the stent lattice. Suitable polymers include polyurethane, polycarbonate urethane, polyurethane urea, silicone rubber, polyisobutylene copolymer (with styrene, etc.), polyolefin, polyester, glycolated polyester, polyamide, amorphous polyamide, combinations of the above and the like. Biodegradable polymers such as Polyisobutyrate, polyvalerate, polylactic acid, polyglycolic acid and combinations of these are also suitable.      The polymer can be reacted in place without a solvent, such as two component polyurethanes, or silicone rubbers, or the reacted polymer can be dissolved in an appropriate solvent, for example, dimethylacetamide for the polyurethanes, toluene for the polyolefins, or heptane for the silicone rubbers. In order to enhance bonding of the polymer to the stent wires, the metallic stent can be primed prior to coating. The hoop strength of a polymer coated stent is improved due to locking of the crossover points and preventing free motion of the stent wires relative to each other.

Title: Treatment of urogenital cancer with boron neutron capture therapy
Inventor: KEANE THOMAS E
IPC: A61K41/00
Filed: 1995-11-06
Abstract: Methods and compositions for treating urogenital tumors, and in particular, cancer of the prostate, bladder, and kidney, with BCNT, are disclosed. Any boron-containing compound that is sufficiently lipophilic to pass through the appropriate urogenital membranes in a quantity high enough to achieve therapy on irradiation with low-energy neutrons can be used. Carboranyl-containing nucleosides and oligonucleotides are particularly suited for use in BNCT of urogenital tumors.  Preferred compounds include 5-carboranyl-2'-deoxyuridine (CDU) and 5-o-carboranyl-l-(2-deoxy-2-fluoro-.beta.-D-arabinofuranosyl)uracil (CFAU). Nucleosides and oligonucleotides bearing an -O-[(carboran-1-yl)alkyl]phosphate, S-[(carboran-1-yl)alkyl]phosphorothioate, or Se-[(carboran-1-yl)alkyl]phosphoroselenoate in place of the (carboran-1-yl)phosphonate moiety can be used. Oligonucleotides of specific gene sequences that include one or more 3', 5'-linking-(carboran-1-yl)phosphonate moieties can also be used in antisense therapy in the selective modification of gene expression. Compounds can be used in urogenital BNCT therapy that contain boron clusters as a means to enhance lipophilicity wherein the boron is not enriched in 10B, but instead, in the 11B isotope. The therapy is accomplished by administering the boron-containing compound by any appropriate route, including by intravenous injection, oral delivery or by catheter or other direct means, in such a manner that the compound accumulates in the target tumor. After desired accumulation of the compound in the tumor, the site is irradiated with an effective amount of low energy neutrons.
