Patent application numberDescriptionPublished
20080206304Medical devices having polymeric regions based on styrene-isobutylene copolymers - According to an aspect of the present invention, implantable or insertable medical devices are provided, which contain one or more polymeric regions. These polymeric regions, in turn, contain one or more polymers, at least one of which is a copolymer that includes a styrene monomer and an isobutylene monomer. Moreover, the styrene monomer content of the copolymer typically ranges from 25 to 50 mol %.08-28-2008
20090018633PROTECTOR FOR AN INSERTABLE OR IMPLANTABLE MEDICAL DEVICE - A protector for a medical device including a tubular member, the tubular member including a polymer matrix material and a scavenger for moisture, oxygen or a combination thereof dispersed in the polymer matrix material.01-15-2009
20090076591Stent Design Allowing Extended Release of Drug and/or Enhanced Adhesion of Polymer to OD Surface - The invention is directed to mechanisms and methods that reduce the delamination of a therapeutic agent from a stent. The mechanisms include holes (channels, wells, and other hole configurations), protrusions, sintered metal cores, clamps/staples, pins, and stainless steel shields.03-19-2009
20090076595Medical devices having bioerodable layers for the release of therapeutic agents - According to an aspect of the present invention, medical devices are provided which comprise: (a) a substrate and (b) bioerodable polymeric layer over the substrate that contains (i) one or more biodegradable polymers, (ii) one or more therapeutic agents, and (iii) one or more plasticizers.03-19-2009
20090096134Process and Apparatus for Forming Medical Device Balloons - Medical device balloons are formed from a tubular parison by a process or apparatus which establishes a controlled location (initiation zone) on the parison where radial expansion is initiated. Initiation within the initiation zone is achieved by heating the parison in that location to a higher temperature than the remainder of the parison for at least a portion of the blowing time. A variety of apparatus configurations are provided, some of which allow for the size and location of the initiation zone to be readily reconfigured. Balloons can also be modified, post-blowing, using heating apparatus and methods described.04-16-2009
20100094213HIGH PERFORMANCE BALLOON CATHETER/COMPONENT - Composite fiber reinforced balloons for medical devices prepared by applying a web of fibers to the exterior of a preformed underlying balloon and encasing the web with a matrix material to form a composite balloon. The fiber web is applied to at least the cone portion of the underlying balloon form. Either the cone portion of the underlying balloon form, or the web fibers applied to said cone portion, or both, have a friction-enhancing material coated thereon.04-15-2010
20100217186Hydrophilic Coating that Reduces Particle Development on Ester-linked Poly(ester-block-amide) - Articles such as catheters or balloons that have an ester-linked poly(ester-block-amide) substrate have a lubricious hydrogel coating which suppresses particle development under accelerated aging conditions. A polymerizable coating composition is applied to the substrate without application of an intervening primer layer and cured. The coating composition comprises an uncrosslinked polyvinylpyrrolidone polymer that is free of attached photoinitiator groups and at least one polyfunctional ethylenically unsaturated monomer.08-26-2010
20100249983EXTRUSION OF ARTICLES - An extrusion control system for use with one or more extruders has a data acquisition module in communication with one or more data acquisition nodes that are associated with an extrusion process. A control module is also in communication with one or more control nodes associated the extrusion process. A synchronization signal to one or more control nodes causes the nodes to adjust to a predetermined setting.09-30-2010
20110165284CATHETER BALLOON MOLD FORM AND MOLDING PROCESS - An immersion mold for a medical device balloon. The mold has a cavity adapted to receive a hollow parison expandable therein to form the balloon. The cavity has a length, a first end, a second end, and a cavity wall with inner and outer surfaces. The mold form cavity wall is provided with one or a plurality of through-holes along the length thereof to facilitate entrance and egress of a heated fluid.07-07-2011
