摘要： Interventional catheter-based systems and methods are described herein for use in generating an initial pathway through vascular occlusions. The catheter systems generally include two elements. A first element is a Blunt Dissection Catheter including a manually actuated assembly located at the distal tip of the Blunt Dissection Catheter that performs blunt dissection in the vascular occlusion to produce a dissection track, or small pathway through the occlusion. The second element is a Sheath Catheter that serves as a conduit within which the Blunt Dissection Catheter is freely advanced, retracted and rotated. The first and second elements are used in some combination to cross vascular occlusions in both the coronary and peripheral vasculature.

摘要： A catheter system and corresponding methods are provided for accessing a blood vessel true lumen from a sub-intimal plane of the vessel. The catheter system includes visualization elements for determining the orientation of the true lumen with respect to the sub-intimal plane at an identified entry site from a position in the sub-intimal plane. The entry site is distal to a chronic total occlusion (CTO). The catheter system also includes a system for physically securing tissue of the sub-intimal plane at the entry site to the catheter system. The attaching system reduces or eliminates catheter float within the sub-intimal space. The catheter system further includes re-entry devices to establish and maintain a path from the sub-intimal plane back into the vessel true lumen.

摘要： Medical devices/methods are described that include catheter systems for crossing total occlusions in vasculature. The catheter systems are for use with numerous guide wires to direct the wires from the extraluminal or subintimal space back into a blood vessel lumen after the wire has entered the subintimal space. The catheter systems comprise a catheter body having at least one lumen configured to track over a wire. An endpiece that includes at least one port in communication with the lumen couples to the distal region of the catheter body. A working element is configured to deploy through the port for delivery from a location within the extraluminal space to locations within the vessel true lumen when advanced distally through the port. A distal region of the catheter body assumes first or second configurations when the working element is retracted into the catheter body.

摘要： Medical devices and methods are described that include catheter systems for use in vasculature. The catheter systems include a re-entry catheter for use with numerous guide wires to direct the guide wire from the extraluminal or subintimal space back into a true lumen after the guide wire has entered the subintimal space. An example of the re-entry catheter is a single lumen catheter configured to facilitate placement and positioning of guide wires and catheters within vasculature. An embodiment places and positions guide wires and catheters within peripheral vasculature. More specifically, the re-entry catheter provides for re-entry of a guide wire back into the true lumen of peripheral vasculature from a subintimal space.

摘要： The present invention discloses various methods and systems for positioning a guide wire between a patient's mouth and a skin site via an implant tract in a stomach. The method includes locating the desired tissue site in the stomach, such as with an endoscope or other suitable instrument. In some embodiments the desired tissue site is marked inside the stomach with a visible dye or light visible from the peritoneal cavity. An implant tract is created through the stomach wall at the desired tissue site, either from “inside-out” or “outside-in”. The implant tract may be made using a RF catheter, RF guide wire, an endoneedle, or other suitable instrument. The size of the implant tract depends on the device to be placed there, such as a stimulation lead. Diameter sizes of the tract may vary from 0.014″ to 0.250″. An access hole or access port is created at a skin site, using a Verres needle, RF catheter, RF guide wire, an endoneedle, or other suitable instrument. A guide wire is then positioned through the implant tract, access port and mouth, such that the guide wire extends between the mouth and the skin site access port via the implant tract in the stomach.

摘要： Devices, systems and methods are provided for electrical stimulation of a body organ, particularly within the gastrointestinal tract. In preferred embodiments, the stomach is the organ within the gastrointestinal tract which is targeted for such stimulation. A guide wire or other delivery device is positioned within the body so as to transect the stomach wall. Devices and systems are then advanced over the guide wire for attachment to the stomach wall. The guide wire may be placed by endoscopic, open, laparoscopic or a modified percutaneous approach. In a modified percutaneous approach, the stomach is accessed without the use of general anesthesia by advancing a needle through the abdomen, transecting the stomach wall with the needle and advancing the guide wire through the needle. In some embodiments, particularly for use in obese patients, the modified percutaneous approach includes advancing a trocar through the tissue of the patient toward the outer surface of the organ and advancing the needle through the trocar prior to transecting the wall with the needle.
