20080262412 | Internal medical devices for delivery of therapeutic agent in conjunction with a source of electrical power - The invention generally relates to internal (e.g., implantable, insertable, etc.) drug delivery devices which contain the following: (a) one or more sources of one or more therapeutic agents; (b) one or more first electrodes, (c) one or more second electrodes and (d) one or more power sources for applying voltages across the first and second electrodes. The power sources may be adapted, for example, to promote electrically assisted therapeutic agent delivery within a subject, including electroporation and/or iontophoresis. In one aspect of the invention, the first and second electrodes are adapted to have tissue of a subject positioned between them upon deployment of the medical device within the subject, such that an electric field may be generated, which is directed into the tissue. Furthermore, the therapeutic agent sources are adapted to introduce the therapeutic agents into the electric field. In another aspect, the therapeutic agent sources are polymeric regions that contain one or more types of ion-conductive polymers and one or more types of charged therapeutic agents. In yet another aspect, the therapeutic agent sources are polymeric regions that contain one or more types of electrically conductive polymers and one or more types of charged therapeutic agents. | 10-23-2008 |
20090068244 | Polymeric/carbon composite materials for use in medical devices - The invention provides implantable or insertable medical devices, which contain one or more composite regions. These composite regions, in turn, contain polymer and carbon particles. Also, the invention provides composite materials for use in a medical device containing styrene-isobutylene copolymer and carbon nanotubes. | 03-12-2009 |
20090118822 | STENT WITH EMBEDDED MATERIAL - An endoprosthesis such as a stent is composed of a metal or ceramic, such as Irox, embedded in the stent material. | 05-07-2009 |
20090125099 | STENT DESIGNS WHICH ENABLE THE VISIBILITY OF THE INSIDE OF THE STENT DURING MRI - A medical device that inhibits distortion of medical resonance images taken of the device. In particular, various structures are utilized to allow visibility proximate, and inside of, a tubular member, such as a stent. In one embodiment, the stent is constructed such that any closed path encircling at least a circumference of the stent will pass through at least two materials to reduce or eliminate electrical loops formed in the stent. | 05-14-2009 |
20100131004 | METHODS AND APPARATUS FOR EMBOLI REMOVAL - Improved methods and apparatus for capturing emboli and subsequently removing or immobilizing the captured emboli are described. Emboli can be captured within a blood vessel and can be withdrawn to a position exterior to the blood vessel. Some filters can remain within a blood vessel yet direct emboli to a position exterior to the blood vessel. | 05-27-2010 |
20110046539 | INTERNAL MEDICAL DEVICES FOR DELIVERY OF THERAPEUTIC AGENT IN CONJUNCTION WITH A SOURCE OF ELECTRICAL POWER - The invention generally relates to internal (e.g., implantable, insertable, etc.) drug delivery devices which contain the following: (a) one or more sources of one or more therapeutic agents; (b) one or more first electrodes, (c) one or more second electrodes and (d) one or more power sources for applying voltages across the first and second electrodes. The power sources may be adapted, for example, to promote electrically assisted therapeutic agent delivery within a subject, including electroporation and/or iontophoresis.

In yet another aspect, the therapeutic agent sources are polymeric regions that contain one or more types of electrically conductive polymers and one or more types of charged therapeutic agents. | 02-24-2011 |
20120046608 | Medical Devices - The invention relates to medical balloons, and methods of modifying said balloons by forming a void pattern in their exterior surfaces and filling the voids with a material, such as a fiber or a nanomaterial (e.g., nanotubes, such as carbon nanotubes) and a matrix material, e.g., a polymer. | 02-23-2012 |
20120197380 | Medical Devices and Related Methods - This disclosure relates to medical devices and related methods. In some embodiments, the methods include applying a material to the balloon and then removing the material from one or more regions of the balloon. | 08-02-2012 |
20130122060 | USING BUCKY PAPER AS A THERAPEUTIC AID IN MEDICAL APPLICATIONS - Methods, systems, and uses of bucky paper are provided in the present invention. These embodiments include covering medical implants with single or multiple layers of bucky paper, treating bucky paper with various therapeutics to be released through the bucky paper to a target site, shaping bucky paper into non-conventional configurations for improved therapeutic deliver, and using bucky paper alone or in conjunction with other materials to treat a target site. | 05-16-2013 |
20140207061 | Medical Devices and Related Methods - This disclosure relates to medical devices and related methods. In some embodiments, the methods include applying a material to the balloon and then removing the material from one or more regions of the balloon. | 07-24-2014 |
