| 20090157043 | LOW PROFILE AGENT DELIVERY PERFUSION CATHETER HAVING A FUNNEL SHAPED MEMBRANE - An agent delivery catheter and method configured to deliver an agent to an inner surface of a patient's body lumen wall by forming a funnel shaped agent containment chamber around at least one portion of the inner surface of the body lumen wall, while minimizing ischemic conditions during the procedure. | 06-18-2009 |
| 20090204068 | AGENT DELIVERY CATHETER HAVING AN INFLATION BRIDGE BETWEEN TWO AXIALLY SPACED BALLOONS - An agent delivery catheter having two or more axially spaced balloons and an inflation bridge providing fluid communication between the two balloons. The catheter generally has a proximal balloon, a distal balloon, and a tube defining an inflation bridge lumen which is located in part within the inflatable interiors of the balloons, and which extends therebetween, and which has a proximal port within the proximal balloon interior and a distal port within the distal balloon interior to thereby provide for inflation of the distal balloon by placing the distal balloon interior in fluid communication with the proximal balloon interior of the shaft. | 08-13-2009 |
| 20090270787 | SYSTEMS AND METHODS FOR CREATING ENLARGED MIGRATION CHANNELS FOR THERAPEUTIC AGENTS WITHIN THE ENDOTHELIUM - A system for enlarging endothelium migration channels at a treatment site in a coronary vessel wall, to enable enhanced delivery of a therapeutic agent thereto. The system includes an enlarging agent, for enlarging endothelium migration channels at a treatment site in a coronary vessel wall. It also includes a delivery system, for delivering the enlarging agent to the treatment site, so that the enlarging agent will be delivered thereby to enlarge the endothelium migration channels at the treatment site, and for delivering the therapeutic agent to the delivery site. The therapeutic agent will thereby be delivered into the enlarged migration channels at the treatment site, to treat the treatment site with the therapeutic agent. | 10-29-2009 |
| 20100145265 | AGENT DELIVERY CATHETER HAVING A RADIALLY EXPANDABLE CENTERING SUPPORT MEMBERS - A catheter for delivering an agent to an injection site in a wall of a patient's body lumen, with an elongated shaft having a needle-through lumen slidably containing a needle therein, and an expandable member on the distal shaft section which has a collapsed configuration and a radially expanded configuration. In the radially expanded configuration, the expandable member supports the shaft in a position spaced away from the body lumen wall, and the needle slidably exits the needle-through lumen in the extended configuration through the port spaced away from the body lumen wall as a portion of the expandable member maintains the position of the port section of the shaft in the body lumen. The expandable member typically has an open-walled, helical, or lobed configuration providing a perfusion path along the expandable member. | 06-10-2010 |
| 20100211009 | PERFUSION CATHETER HAVING ARRAY OF FUNNEL SHAPED MEMBRANES - An agent delivery catheter configured to deliver an agent to an inner surface of a patient's body lumen wall by forming an array of cells defining agent containment chambers at multiple locations along the catheter's shaft, while minimizing ischemic conditions during the procedure. | 08-19-2010 |
| 20110238039 | Method and Apparatus for Improving Delivery of an Agent to a Kidney - Methods for more uniformly delivering drugs or other treatment agents locally to the vasculature of a mammal are disclosed. These methods use one or more strategies to facilitate rapid mixing with the blood flowing past a device or otherwise improve the uniformity of drug delivery. Some of these strategies employ medical devices with diffusion members. | 09-29-2011 |

| 20110281020 | Maintaining A Fixed Distance During Coating Of Drug Coated Balloon - A system and method for coating an expandable member of a medical device comprising a support structure to support the expandable member and a dispenser positioned with at least one outlet proximate a surface of an expandable member. A drive assembly establishes relative movement between the at least one outlet and the surface of the expandable member to apply fluid on the surface of the expandable member along a coating path. A guide maintains a substantially fixed distance between the at least one outlet and the surface of the expandable member during relative movement therebetween by displacing the expandable member relative to the at least one outlet. | 11-17-2011 |
