Temporary vascular filter guide wire

Abstract: A temporary filter is described for use in percutaneous intravascular procedures for the treatment of diseased blood vessels, such as angioplasty or stent placement procedures. The guide wire which is used to direct a catheter (such as a balloon catheter) to a treatment site contains a deployable filter. The guide wire is moveable independently of the catheter and can be used to position the filter at a desired location downstream of the treatment site. The guide wire includes parts moveable with respect to each other and the filter is connected to these parts in such a way that it can be deployed and collapsed by relative movement of the parts.

Polymer compositions containing colloids of silver salts

Abstract: 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 metal, 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. The compositions can be incorporated into articles or can be employed as a coating on articles such as medical devices.

Method and apparatus for control of ablation energy and electrogram acquisition through multiple common electrodes in an electrophysiology catheter

Abstract: Method and apparatus for control of ablation energy and electrogram acquisition through multiple common electrodes in an electrophysiology catheter. A device that routes ablation energy to and that routes mapping signals received from an electrophysiology catheter having a plurality of conductive filaments including circuitry that provides, for each conductive filament when ablation energy is being delivered, an electrical signal path that has a low impedance for ablation energy and a high impedance for mapping signals. The device also includes circuitry that provides, for each conductive filament, when mapping signals are being received, an electrical signal path that has a high impedance for ablation energy and low impedance for mapping signals. At least one switch is provided that selectively groups electrodes into sectors for delivery of ablation energy.

Thromboresistant coating using silanes or siloxanes

Abstract: Coatings are provided in which biopolymers may be covalently linked to a substrate. Such biopolymers include those that impart thromboresistance and/or biocompatibility to the substrate, which may be a medical device. Coatings disclosed herein include those that permit coating of a medical device in a single layer, including coatings that permit applying the single layer without a primer. Suitable biopolymers include heparin complexes, and linkage may be provided by a silane having isocyanate functionality. Plasma deposition and solvent swelling techniques are described as preferred methods of depositing a derivatized silane or a silane-heparin coating.

Self anchoring sling and introducer system

Abstract: A system for supporting the urethra using an introducer needle (3), the ends (4) of which are flattened and which have openings therethrough, a handle (5) having a latch mechanism (35) which engages the opening in the flattened portion of the first end of the introducer needle (3), an implant (1), and a connector (7) joining the end of the implant (1) to the flattened portion of one of the ends of the introducer needle (3). These components are used to draw the implant (1) into position, either through vaginal or abdominal incisions, to form a U-shaped loop beneath the urethra. The ends of the implant (1) are adjusted to provide proper support for the urethra. The implant (1) can have slits that open under applied tensile force.
