| 20100324471 | Systems and Methods for Delivering Drugs to Selected Locations Within the Body - A transvascular system for delivering a drug to a tissue region from a blood vessel includes a catheter having a distal portion with puncturing, orientation, drug delivery, and imaging elements. The puncturing element is deployable for penetrating the vessel wall to access the tissue region. The orientation element has a predetermined relationship with the puncturing element, the imaging element detecting the location of the orientation element with respect to the tissue region to orient the puncturing element. The catheter is percutaneously introduced into the vessel, the puncturing element is oriented towards the tissue region, the puncturing element is deployed to access the tissue region, and the drug is delivered to the tissue region. An ablation device may also be deployed to create a cavity or fluid reservoir in the tissue region for receiving the drug therein, or an indwelling catheter may be advanced into and left in the tissue region. | 12-23-2010 |

| 20100121357 | Tissue Penetrating Catheters having Integral Imaging Transducers and Their Methods of Use - A catheter device that is useable to penetrate from a blood vessel in which the catheter device is positioned to a target location comprises a flexible catheter advanceable into the first blood vessel, a tissue penetrator lumen adapted to receive an operative tissue penetrator which is usable to penetrate from the blood vessel to the target location when properly aimed. Further said catheter including an imaging transducer fixedly mounted on or within the catheter body to provide an imaging signal from which an image of the target location can be obtained. The catheter device may include an imageable marker on the catheter to form on the image obtainable from the imaging signal a penetrator path indication that indicates the path that will be followed by the tissue penetrator when the tissue penetrator exits from the catheter. Alternatively, or addition thereto, the imaging transducer may comprise a plurality of imaging elements which are located so that the penetrator path indication can be obtained. A method of utilizing such a catheter device to bypass an arterial obstruction is also disclosed. | 05-13-2010 |
