Patent application numberDescriptionPublished
20080317813Nanobead releasing medical devices - Medical devices comprising nanobeads encapsulating one or more bioactive agents and methods of use thereof are provided.12-25-2008
20090093875DRUG ELUTING STENTS WITH PROLONGED LOCAL ELUTION PROFILES WITH HIGH LOCAL CONCENTRATIONS AND LOW SYSTEMIC CONCENTRATIONS - A drug eluting stent can include a stent body having a polymeric coating with a lipophilic and/or hydrophilic element. A drug that has a bioactivity that inhibits cell proliferation can be disposed in the polymeric coating. The drug can be present in the polymer at an amount greater than or equal to about 150 ug/cm04-09-2009
20090131971GUIDE WIRE WITH EMBOLIC FILTERING ATTACHMENT - A separate deliverable embolic protection device filter that attaches to a helical coil at a distal end of a conventional guide, for use in a blood vessel when an interventional procedure is being performed to capture any embolic material which may be created and released into the bloodstream during the procedure. The device includes a filter assembly with a proximal end and a distal end, and a guide wire connector attached to the distal end of the filter assembly. The guide wire connector is able to couple with the helical coil of the guide wire. A restraining sheath placed over the filter assembly in a coaxial arrangement maintains the filter assembly in a collapsed position and delivers the filter assembly separately to the helical coil of the guide wire, and then the guide wire connector is joined to the helical coil. Alternatively, the guide wire can include a rotatable coil section forming a portion of the distal tip coil on the guide wire which is adapted to be coupled to the filter assembly. This arrangement allows the filter assembly to be rotatably mounted onto the guide wire.05-21-2009
20100036472DELIVERY SYSTEM WITH VARIABLE DELIVERY RATE FOR DEPLOYING A MEDICAL DEVICE - A delivery system utilizes a handle assembly including an actuating mechanism capable of initially providing sufficient mechanical advantage to overcome static friction when initiating deployment of the medical device. The actuating mechanism includes components which help to increase the speed of deployment as the physician continues to manipulate the actuating mechanism.02-11-2010
20100049240CAGE AND SLEEVE ASSEMBLY FOR A FILTERING DEVICE - A cage and sleeve assembly for an embolic filtering device used to filter embolic particles from a body vessel has a strut assembly that is movable between an unexpanded position and an expanded position. Struts having strut ends at the respective ends form a cage. The strut ends are initially made from linear elastic nitinol, and a series of spot or laser or other types of welds then secure the strut ends in the sleeve assembly. In one approach, the ends of the strut ends are welded to form a tube. In another approach, the strut ends are welded onto a sleeve. The strut ends may optionally have ends that are partial cylinders, and the partial cylinders are welded onto a cylindrical sleeve. Effects from the welding, such as changing linear elastic nitinol to superelastic nitinol, are contained within a heat-effected zone, and do not extend into areas of the structure that typically bend during use.02-25-2010
20100049305CONVERTIBLE DELIVERY SYSTEMS FOR MEDICAL DEVICES - A delivery system for a medical device or other devices to be deployed within a biological body including a sheath having a longitudinal joint. The joint can be either resealable or non-resealable. The joint remains intact during delivery of the medical device, thereby facilitating accurate delivery of the medical device. During removal of the sheath, the joint is separated, thereby permitting the sheath to be peeled from the medical device while maintaining the position of the device. The delivery system allows a single operator to deploy the medical device and remove the sheath.02-25-2010
20100104734COATED STENT AND METHOD OF MAKING THE SAME - A coated implantable medical device and a method of coating an implantable medical device is disclosed, the method includes applying a composition onto the device and drying the composition at elevated temperature in an environment having increased relative humidity. A pre-screening method for a manufacturing lot of coated stents to determine the number of drug coating layers for a desired drug release rate is disclosed. The method including coating and testing small groups of stents, and applying the results of the tests to determine the number of drug coating layers to apply to the manufacturing lot of stents.04-29-2010
20100174355DELIVERY AND RECOVERY SHEATHS FOR MEDICAL DEVICES - A deployment control system provides controlled deployment of an embolic protection device which may include a guide wire, an expandable filter attached to the guide wire near its distal end, and a restraining sheath that maintains the expanded filter in a collapsed position. The deployment control system includes a torque control device which allows the physician to torque the guide wire into the patient's anatomy and a mechanism for preventing the guide wire from buckling as the restraining sheath is being retracted to deploy the expandable filter. A recovery control system for recovering the embolic protection device includes an inner catheter which extends within a lumen of an outer recovery sheath in a coaxial arrangement. A distal portion of the inner catheter extends beyond another recovery sheath during advancement of the recovery system into the vasculature. The recovery sheath can be advanced over the inner catheter to collapse the expandable filter. The proximal ends of the inner catheter and recovery sheath include handle portions having snap mechanisms which hold the components together as the recovery system is being advanced into the patient's vasculature.07-08-2010
20110004238INTRAVASCULAR DEVICE AND SYSTEM - A device for use in capturing or collecting debris found in blood vessels or other body lumens. The devices can be fabricated from a tube and include longitudinally and circumferentially extending members. The device can further embody structure that provides enhanced radial opening and angular resistance to collapse and structure for absorbing or modifying forces applied thereto by an operator.01-06-2011
20110029008GUIDE WIRE WITH EMBOLIC FILTERING ATTACHMENT - A separate deliverable embolic protection device filter that attaches to a helical coil at a distal end of a conventional guide, for use in a blood vessel when an interventional procedure is being performed to capture any embolic material which may be created and released into the bloodstream during the procedure. The device includes a filter assembly with a proximal end and a distal end, and a guide wire connector attached to the distal end of the filter assembly.

This arrangement allows the filter assembly to be rotatably mounted onto the guide wire.02-03-2011
20110034992Stent and Method of Coating Same - Coating a stent may include continuously rotating the stent in one direction while spraying a first coating layer followed by continuously rotating the stent in another direction while spraying a second coating layer, wherein the first layer is preferentially distributed over a side surface of the stent struts and the second layer is preferentially distributed over an opposite side surface of the stent struts. The overall coating distribution combining both layers may be evenly distributed over the two side surfaces of the stent struts.02-10-2011
20110039013System and Method for Coating a Medical Device - A system and method allows for processing of two groups of medical devices, both groups being alternatingly spray coated within the same enclosure. The two groups repeatedly move back and forth between a spray area and a drying area which is isolated from the spray area. One group moves into the spray area as the other group moves out and into the drying area. Thereafter, the group in the spray area moves out and into the drying area and the other group moves back into the spraying area for a second coating. The alternating process may be repeated any number of times. The spray area may be located inside a sealed spray isolator enclosure and surrounded by gas discharge nozzles.02-17-2011
20110059228Drug-Eluting Coatings Applied To Medical Devices By Spraying And Drying To Remove Solvent - A coating device for coating a medical device with a drug-eluting material uses an in-process drying station between coats to improve a drug release profile. The drying station includes a heat nozzle configured for applying a uniform drying gas. A coating process using the dryer includes a closed-loop control for the gas between drying steps and an improved nozzle for producing more consistent spray patterns.03-10-2011
