Abstract:
PROBLEM TO BE SOLVED: To provide a self-expandable relocatable device usable as a stent, occluder, or filter with a both ends closing structure. SOLUTION: The self expandable woven intravascular device 160 which is used as the stent, filter, or occluder may be formed of a shape memory metal or a biodegradable material. A delivery system for the device includes two hollow tubes that are operated coaxially. One end of the device may be secured to the outside of the inner tube and the other end 162, 164 of the device may be secured to the outside of the outer tube. The device may be formed of a single wire. The device may be formed by either hand or machine weaving. The device may be created by bending shape memory wires around tabs projecting from a template, and weaving the ends 170 of the wires to create the body 160 of the device such that the wires cross each other to form a plurality of angles, at least one of the angles being obtuse. The value of the obtuse angle may be increased by axially compressing the body. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To increase the number of target options by identifying further targets enabling the destruction of specific tumor blood vessels in vivo for further target treatment of blood vessels, and further to provide a method for preparation of a one-component drug for the destruction of tumor blood vessels. SOLUTION: There are disclosed the surprising discoveries that aminophospholipids (for example, phosphatidylserine and phosphatidylethanolamine) are stable and specific markers accessible on the luminal surface of tumor blood vessels, and that the administration of an anti-aminophospholipid antibody alone is sufficient to induce thrombosis, tumor necrosis and tumor regression in vivo. This invention therefore provides anti-aminophospholipid antibody-based methods and compositions for use in the specific destruction of tumor blood vessels and in the treatment of solid tumors.

Abstract:
A non-metallic antimicrobial impregnated medical implant, such as a catheter, and a method for impregnating a non-metallic medical implant with an antimicrobial agent is provided. The method for making the impregnated implant comprises the steps of forming an antimicrobial composition of an effective concentration to inhibit the growth of organisms, such as staphylococci, other gram-positive bacteria, gram-negative bacilli and Candida and applying the antimicrobial composition to at least a portion of the medical implant under conditions where the antimicrobial composition permeates the material of the medical implant. The antimicrobial composition is formed by dissolving an antimicrobial agent in an organic solvent, adding a penetrating agent to the composition, and adding an alkalinizing agent to the composition. The antimicrobial composition is preferably heated to a temperature between about 30 DEG C. and 70 DEG C. prior to applying the composition to the medical implant to enhance the adherence of the antimicrobial agent to the medical implant material. After the impregnated implant is removed from the antimicrobial solution, the impregnated implant is allowed to dry then rinsed with a liquid and milked to remove excess granular deposits and ensure uniform color of the impregnated implant.
