US Classification:

60416412, 60416409

Abstract:

A system of catheter devices and methods for forming channels or passageways between a luminal anatomical structure (e. g. , a blood vessel) and a target location (e. g. , another blood vessel, an organ, a mass of tissue, etc. ) for the purpose of rerouting blood flow or for delivering a substance or instrument, etc. to the target location.

International Classification:

A61B 1708

US Classification:

606155, 606153

Abstract:

Anastomotic connectors and apparatus for forming and/or maintaining connections between openings formed in anatomical structures, such as blood vessels. The apparatus is initially deployed in a first configuration which is sufficiently compact to be delivered through the lumen of a catheter or cannula. Thereafter, the device is expanded to a second configuration whereby it engages the anatomical structures and forms or maintains the desired connection between openings in the anatomical structures.

International Classification:

A61M 2900

US Classification:

606200

Abstract:

This invention is methods and apparatus for occluding blood flow within a blood vessel ( ). In a first series of embodiments, the present invention comprises a plurality of embolic devices ( ) deployable through the lumen ( ) of a conventional catheter ( ) such that when deployed, said embolic devices ( ) remain resident and occlude blood flow at a specific site within the lumen of the blood vessel ( ). Such embolic devices ( ) comprise either mechanical embolic devices that become embedded within or compress against the lumen of the vessel or chemical vaso occlusive agents that seal off blood flow at a given site. A second embodiment of the present invention comprises utilization of a vacuum/cauterizing device capable of sucking in the lumen of the vessel about the device to maintain the vessel in a closed condition where there is then applied a sufficient amount of energy to cause the tissue collapsed about the device to denature into a closure. In a third series of embodiments, the present invention comprises the combination of an embolization facilitator coupled with the application of an energy force to form an intraluminal closure at a specified site within a vessel.

International Classification:

A61B 1900

US Classification:

128898

Abstract:

Methods, devices, and systems for a) revascularization and/or b) performing other medical procedures at vascular or non-vascular intracorporeal locations within a mammalian body. The methods generally comprise the formation of at least one extravascular passageway from a blood vessel to a vascular or non-vascular target location. In the revascularization methods the extravascular passageway is utilized for blood flow. In the medical procedure methods the extravascular passageway is utilized as a conduit for accessing or performing procedures at the vascular or non-vascular target location. Also disclosed are catheter devices and systems which are useable to form the extravascular passageways of the invention, as well as apparatus for modifying, maintaining and/or closing such extravascular passageways.

Abstract:

A method is provided for delivering a drug to a selected tissue region within a patients body with a catheter having a deployable puncturing element, a drug delivery element and an orientation element on a distal portion thereof. The distal portion of the catheter is percutaneously introduced into a blood vessel, and directed endovascularly to a vessel location adjacent to the selected tissue region. The puncturing element is oriented towards the selected tissue region, and deployed to access the selected tissue region. A drug is delivered with the drug delivery element to the selected tissue region.
