Patent application numberDescriptionPublished
20100117885ELECTROMAGNETIC SCANNING IMAGER - In one aspect, the present invention provides an imager, preferably portable, that includes a source of electromagnetic radiation capable of generating radiation with one or more frequencies in a range of about 1 GHz to about 2000 GHz. An optical system that is optically coupled to the source focuses radiation received therefrom onto an object plane, and directs at least a portion of the focused radiation propagating back from the object plane onto an image plane. The imager further includes a scan mechanism coupled to the optical system for controlling thereof so as to move the focused radiation over the object plane. A detector optically coupled to the lens at the image plane detects at least a portion of the radiation propagating back from a plurality of scanned locations in the object plane, thereby generating a detection signal. A processor that is in communication with the detector generates an image of at least a portion of the object plane based on the detection signal.05-13-2010

20080215136DIFFERENTIAL DRUG RELEASE FROM A MEDICAL DEVICE - The invention relates to a medical device, such as an intravascular stent, useful for delivering two or more therapeutic agents to a body tissue of a patient at different rates, and methods for making and using such medical device. The medical device includes a substrate and/or coating having a plurality of pores, dispersed in said pores are a plurality of a first and second therapeutic agents, wherein said first therapeutic agent is bonded to one or more molecule(s) of a first material and the second therapeutic agent bonded to one or more molecule(s) of a second material, such that when the medical device, is in use (e.g., implanted into a body lumen such as a blood vessel), bonded first therapeutic agent is released from the medical device at a rate that is slower than the rate at which the bonded second therapeutic agent is released from the medical device.09-04-2008
20090118820DEFORMABLE UNDERLAYER FOR STENT - An endoprosthesis includes a brittle layer, e.g. a ceramic and an underlayer to accommodate dimensional changes as the endoprosthesis is flexed.05-07-2009
20090216185BALLOON CATHETER WITH DURABLE TIP PORTION - A durable distal tip structure for an intravascular catheter that may include a distal portion comprising a ring of durable material configured to provide a durable distal tip to the catheter, and a proximal portion extending proximally from the distal portion and configured for connecting the distal tip structure to the catheter, wherein the proximal portion of the distal tip structure is more laterally flexible than the distal portion. In some cases, the durable distal tip structure comprises a metal or metal alloy, and in some cases, the distal ring portion and proximal portion of the durable distal tip structure comprise a single monolith of material. Also, catheters including such durable distal tip structures, and methods of making and using such catheters. In some cases, the catheter is a balloon catheter. In some other embodiments, the catheter is a stent delivery catheter for a self expanding stent.08-27-2009
