20080215139 | STENT WITH A COATING FOR DELIVERING A THERAPEUTIC AGENT - The invention relates generally to a medical device for delivering a therapeutic agent to the body tissue of a patient, and methods for making such a medical device. More particularly, the invention is directed to a stent, such as an intravascular stent, having an inner and outer coating compositions disposed thereon. In another embodiment, the inner coating composition and outer coating composition are separated by a barrier coating composition. | 09-04-2008 |
20100274342 | STENT CRIMPING MECHANISMS - A system for reducing the diameter of a stent comprises a stent contracting assembly. The assembly comprises a plurality of blades, which define a diameter reduction chamber. The chamber has an open diameter configuration and a closed diameter configuration. The plurality of blades comprises active blades and floating blades, wherein each active blade is engaged to an actuation mechanism. The actuation mechanism is constructed and arranged to move each active blade from the open diameter configuration to the closed diameter configuration. Each floating blade is moved from the open diameter configuration to the closed diameter configuration only as a result of the movement of the active blades. | 10-28-2010 |
20110245767 | BALLOON FOLDING APPARATUS, METHODS AND PRODUCTS - A medical balloon may be configured by at least partially inflating the medical balloon and forming at least one primary lobe in the balloon. The primary lobe extends from a central portion of the balloon. The primary lobe may be manipulated to form at least two secondary lobes therefrom. The balloon may then be deflated and the secondary lobes wrapped around the balloon. | 10-06-2011 |
