  • Publication number: 20110190870
    Abstract: A stent assembly includes a stent, a covering on at least a portion of the stent, and a string encircling at least a portion of the covering. The string is releasably engaged to the covering or stent or both the covering and the stent. The string can be adhered to the stent, or the stent assembly, to the covering of the stent assembly, or both the covering and the stent. The string can be wrapped around the stent or covering in an interwoven loop or knit pattern. The covering can be made to overlap a perforation in a body lumen such as an artery or blood vessel and prevent bleeding.

  • Publication number: 20110034939
    Abstract: Some embodiments of an electrical stimulation system employ wireless electrode assemblies to provide pacing therapy, defibrillation therapy, or other stimulation therapy. In certain embodiments, the wireless electrode assemblies may include a guide wire channel so that each electrode assembly can be advanced over a guide wire instrument through the endocardium. For example, a distal tip portion of a guide wire instrument can penetrate through the endocardium and into the myocardial wall of a heart chamber, and the electrode assembly may then be advanced over the guide wire and into the heart chamber wall. In such circumstances, the guide wire instrument (and other portions of the delivery system) can be retracted from the heart chamber wall, thereby leaving the electrode assembly embedded in the heart tissue.

  • Patent number: 7848823
    Abstract: Some embodiments of pacing systems employ wireless electrode assemblies to provide pacing therapy. The wireless electrode assemblies may wirelessly receive energy via an inductive coupling so as to provide electrical stimulation to the surrounding heart tissue. In certain embodiments, the wireless electrode assembly may be pivotable so that the proximal end of the wireless electrode assembly may be shifted to a position against the heart wall after the distal end has been secured to the heart wall.

  • Publication number: 20090299269
    Abstract: A system and method are described involving the use of a cell delivery catheter that incorporates a stimulating electrode to promote vasodilation prior to injection of cells at a target location within a blood vessel. The vasodilation may be produced locally and/or distally from the target location near the target organ. The technique may be applied not only to intra-coronary injection of cells to treat heart disease but to injection of cells in any blood vessel that feeds a target organ.

  • Publication number: 20090234407
    Abstract: An apparatus and method can receive wireless energy using a wireless electrostimulation electrode assembly. In certain examples, at least some of the received wireless energy can be delivered as an electrostimulation to a heart. In certain examples, the wireless electrostimulation electrode can be mechanically supported at least partially using a ring formed by an annulus of a mitral valve of the heart. In certain examples, the wireless electrostimulation electrode assembly can be configured to be intravascularly delivered to an implant location within a chamber of the heart at the annulus of the mitral valve of the heart, and can fit entirely within the heart.

  • Publication number: 20090204170
    Abstract: A wireless electrostimulation system can comprise a wireless energy transmission source, and an implantable cardiovascular wireless electrostimulation node. A receiver circuit comprising an inductive antenna can be configured to capture magnetic energy to generate a tissue electrostimulation. A tissue electrostimulation circuit, coupled to the receiver circuit, can be configured to deliver energy captured by the receiver circuit as a tissue electrostimulation waveform. Delivery of tissue electrostimulation can be initiated by a therapy control unit.

  • Publication number: 20080314394
    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: 20080047568
    Abstract: A method of turning a medical device, having a magnetically responsive element associated with its distal end, at an operating point within an operating region inside a patient's body from an initial direction to a desired final direction, through the movement of at least one external source magnet. The at least one external source magnet is moved in such a way as to change the direction of the distal end of the magnetic medical device from the initial direction to the desired final direction without substantial deviation from the plane containing the initial direction and the desired final direction.

  • Publication number: 20080021505
    Abstract: Some embodiments of a cardiac stimulation system may include a plurality of electrode assemblies that are interconnected by one or more wires while at least one of the electrode assemblies (e.g., a control electrode) wirelessly receives energy through inductive coupling with a power communication unit external to the heart (e.g., a device implanted along one or more ribs). These embodiments may provide an arrangement for efficient inductive coupling from the power communication unit to the control electrode. Also, in some circumstances, the cardiac stimulation system may eliminate the need for wired leads that extend to a location outside the heart, thereby reducing the likelihood of infection that passes along the wire and into the heart.
