Publication number: 20090306703Abstract: A removable blood clot filter includes a number of locator members and anchor members, and a bio-resorbable structure that causes locator members and/or anchor members to deploy to an initial configuration which changes when the bio-resorbable structure is resorbed. The bio-resorbable structure causes the filter locator members and/or anchor members to press against the vessel wall sufficient to locate and anchor the filter upo delivery. After the bio-resorbable structure is resorbed, the locator member's and/or anchor members change shape to apply less pressure against the vessel wall. The bio-resorbable structure may be activated by exposure to radiation so that actuation of the locator members and/or anchor members can be enabled or initiated by a clinician.Type: ApplicationFiled: December 29, 2006Publication date: December 10, 2009Applicant: C.R.

Publication number: 20090293882Abstract: The present invention relates to antimicrobial compositions, methods for the production of these compositions, and use of these compositions with medical devices, such as catheters, and implants. The compositions of the present invention advantageously provide varying release kinetics for the active ions in the compositions due to the different water solubilities of the ions, allowing antimicrobial release profiles to be tailored for a given application and providing for sustained antimicrobial activity over time. More particularly, the invention relates to polymer compositions containing colloids comprised of salts of one or more oligodynamic metals, such as silver. The process of the invention includes mixing a solution of one or more oligodynamic metal salts with a polymer solution or dispersion and precipitating a colloid of the salts by addition of other salts to the solution which react with some or all of the first metal salts.Type: ApplicationFiled: August 10, 2009Publication date: December 3, 2009Applicant: C.R.
