  • Patent number: 7832406
    Abstract: Devices and methods for creating a series of percutaneous myocardial revascularization (PMR) channels in the heart. One method includes forming a pattern of channels in the myocardium leading from healthy tissue to hibernating tissue. Suitable channel patterns include lines and arrays. One method includes anchoring a radiopaque marker to a position in the ventricle wall, then using fluoroscopy repeatedly to guide positioning of a cutting tip in the formation of multiple channels. Another method uses radiopaque material injected into each channel formed, as a marker. Yet another method utilizes an anchorable, rotatable cutting probe for channel formation about an anchor member, where the cutting probe can vary in radial distance from the anchor. Still another method utilizes a multiple wire radio frequency burning probe, for formation of multiple channels simultaneously. Still another method utilizes liquid nitrogen to cause localized tissue death.

  • Publication number: 20080015627
    Abstract: An intra-bronchial device may be placed in an air passageway of a patient to collapse a lung portion associated with the air passageway. The device includes an obstructing member that prevents air from being inhaled into the lung portion to collapse the lung portion, and an anchoring device that anchors the obstructing member in the air passageway by engaging the obstructing member and the air passageway wall. The anchoring device may frictionally engage the obstructing member and the air passageway, or engage both by piercing. The engagement provided by the anchoring device may be releasable for removal of the obstructing member. The anchoring device may be balloon expandable from a first shape to a second shape that engages the obstructing member and the air passageway. The obstructing member may be a one-way valve.

  • Publication number: 20050137591
    Abstract: An electrosurgery device according to an embodiment of the invention captures a lymph nodule and resects it. The lymph node is captured with a vacuum and resected it with an electrode, which minimizes bleeding and limits the potentially malignant node from coming into contact with surround tissue as it is resected and removed. This limits the potential for inadvertent cancer spread. An electrosurgery device according to an embodiment of the invention also allows several lymph nodes to be resected in a single procedure, each lymph node being easily indexed according to its nodal station and stored in a manner that limits the potential for cross-contamination. An electrosurgery device according to an embodiment of the invention further provides a collector for individually receiving resected lymph nodes. The collector may be easily detached and sent to pathology without interrupting resection of other lymph nodes.

  • Publication number: 20050033344
    Abstract: An intra-bronchial device placed and anchored in an air passageway of a patient to collapse a lung portion associated with the air passageway. The device includes a support structure, an obstructing member carried by the support structure that reduces ventilation to the lung portion by preventing air from being inhaled into the lung portion, and at least one anchor carried by the support structure that anchors the obstruction device within the air passageway. The anchor may engage the air passageway wall by piercing or friction, include a stop dimensioned for limiting the piercing of the air passageway wall, and may be releasable from the air passageway for removal of the intra-bronchial device. The anchors may be carried by a peripheral portion of the support structure, or by a central portion of the support structure. The obstructing member may be a one-way valve.

  • Patent number: 6660003
    Abstract: An intravascular device and methods for forming multiple percutaneous myocardial revascularization (PMR) holes in a heart chamber wall simultaneously. One device includes a basket formed of flexible arms carrying cutting probes over their length. The basket arms are outwardly arcuately biased so as to assume an outwardly bowed, arcuate shape when unconstrained. The device includes an inner shaft distally secured to a proximal portion of the basket and slidably disposed within an outer shaft. The inner shaft and collapsed basket can be retracted within the outer shaft, delivered intravascularly to the left ventricle, and distally advanced, forcing the basket to assume the bowed shape. Radio frequency current supplied to the electrical cutting probes burn holes into the ventricle wall and myocardium. One embodiment has high pressure fluid jet cutting means. Another embodiment uses a basket as an anchor to position a steerable cutting probe.

  • Publication number: 20020143289
    Abstract: A catheter having an elongate shaft including a proximal and a distal end. The shaft includes a conductor. An electrode is disposed at the distal end of the shaft and is connected to the conductor. The electrode has a generally annular, cross-sectional shape. The annular shape defines an opening within the electrode. An insulator surrounds the conductor. In accordance with the method of the present invention, a crater wound can be formed through the endocardium and into the myocardium of a patient's heart. Collateral damage to the myocardium can be made by infusing pressurized fluid into the crater wound.
