Publication number: 20070034527Abstract: An electropolishing device for polishing a cylindrical medical device such as a stent includes anodes in the form of rollers arranged to contact an exterior surface of the device. A drive mechanism rotates the anodes periodically during the electropolishing process to change a contact point between the anodes and the medical device. A tilting mechanism can also be used for periodically tilting the anodes during the electropolishing process to allow bubbles to escape from one end of the stent.Type: ApplicationFiled: August 11, 2006Publication date: February 15, 2007Applicant: Conor Medsystems, Inc.Inventors: Stephen Diaz, Jeffrey Anderson

Publication number: 20060222755Abstract: A system for loading a beneficial agent into holes in a medical device includes a punch system for punching plugs of beneficial agent from a thin sheet into the holes in the medical device. The loading of a beneficial agent in the form of a thin film allows the formation of multilayered structures within the holes to control release kinetics and prevent any meniscus which occurs when a beneficial agent is deposited as a liquid in the holes and dried. The punch type loading system also can provide the ability to deliver large and potentially sensitive molecules including proteins, enzymes, antibodies, antisense, ribozymes, gene/vector constructs, and cells including endothelial cells.Type: ApplicationFiled: March 28, 2006Publication date: October 5, 2006Applicant: Conor Medsystems, Inc.Inventors: Stephen Diaz, Theodore Parker

Publication number: 20060222679Abstract: A system for delivery of a beneficial agent in the form of a viscous liquid or paste allows holes in a medical device to be loaded in a single step process. The loading of a beneficial agent in a paste form also provides the ability to deliver large and potentially sensitive molecules including proteins, enzymes, antibodies, antisense, ribozymes, gene/vector constructs, and cells including endothelial cells.Type: ApplicationFiled: March 28, 2006Publication date: October 5, 2006Applicant: Conor Medsystems, Inc.Inventors: John Shanley, Stephen Diaz, Theodore Parker

Publication number: 20060177564Abstract: The beneficial agent is applied into the holes in a medical device in a dry particulate form and is adhered in the hole in a manner that allows release of the drug in a controlled manner. The drug material would be formed into particles and placed in the holes. The solvent would be added to partially liquefy and adhere the drug into the holes. After application of the solvent, the particles are adhered together in a substantially uniform drug containing matrix. The particles may include drug alone or drug in combination with other materials including a matrix.Type: ApplicationFiled: March 28, 2006Publication date: August 10, 2006Applicant: Conor Medsystems, Inc.Inventors: Stephen Diaz, Theodore Parker

Publication number: 20060178734Abstract: A method for decreasing the level of restenosis following a stent placement medical intervention involves the continuous administration of a dose of an anti-restenotic agent, such as paclitaxel, from the stent to vascular tissue in need of treatment in a controlled, extended, and substantially linear drug release profile. The method of substantially linear extended release increases the therapeutic effectiveness of administration of a given dosage. In one example, a method of reducing restenosis includes delivering paclitaxel from a stent to an artery at a minimum release rate of 1 percent of the total dosage of paclitaxel on the stent per day throughout an entire administration period from the time of implantation of the stent until the time that substantially all the paclitaxel is released from the stent.Type: ApplicationFiled: January 4, 2006Publication date: August 10, 2006Applicant: Conor Medsystems, Inc.Inventors: Theodore Parker, John Shanley, Brett Trauthen, Frank Litvack, Stephen Diaz

Publication number: 20060079956Abstract: A bifurcation stent includes a first end which is deformable or crushable at a lower force than a second end. The crushable first end and more rigid second end of the bifurcation stent allow one end of the stent to remain expanded in tissue supporting configuration in a side branch of a vessel bifurcation while the other end is easily crushed against the side wall of the main vessel into which it extends. A method of supporting a bifurcated body lumen with the bifurcation stent involves delivering the bifurcation stent in an unexpanded configuration to a bifurcation in a body lumen, positioning the bifurcation stent with the distal portion substantially within a side branch vessel of the bifurcation and the proximal crushable portion substantially within the main vessel, expanding the bifurcation stent, and expanding a main vessel stent along side the bifurcation stent and thereby crushing at least a portion of the crushable proximal portion of the bifurcation stent against the main vessel wall.Type: ApplicationFiled: August 10, 2005Publication date: April 13, 2006Applicant: Conor Medsystems, Inc.Inventors: Neal Eigler, Frank Litvack, John Shanley, Stephen Diaz

Publication number: 20050234538Abstract: A method and system for delivering a bioresorbable intravascular stent includes a delivery system or catheter having an expandable balloon. A guidewire lumen having a distal guidewire port and a proximal guidewire port spaced a relatively short distance from the distal end allows rapid exchange of the stent delivery system over a guidewire.Type: ApplicationFiled: March 31, 2005Publication date: October 20, 2005Applicant: Conor Medsystems, Inc.Inventors: Frank Litvack, Jonh Shanley, Theodore Parker, Stephen Diaz
