  • Publication number: 20090082827
    Abstract: A hinged anchor for a medical device electrode is disclosed. In one embodiment, the hinged anchor has a hinged portion and an anchor portion. The hinged portion can have a first configuration forming a first angle and a second configuration forming a second angle. The second angle can be a sharper angle than the first angle, and the hinged portion can be predisposed to assume the second configuration. The hinged anchor can be disposed on a control module of a leadless microstimulator device.

  • Publication number: 20070150009
    Abstract: Apparatus, system, and method that include a pacing apparatus having a stent electrode through which pulses of electrical current can be delivered. Stent electrodes receive energy for generating the electrical current from a variety of sources. Sources include from one or more induction coils that can form at least a portion of the stent. Sources can also include an implantable pulse generator coupled to a lead through which pulses of the electrical current are supplied to the stent electrodes.

  • Publication number: 20070135883
    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 include one or more biased tines that shift from a first position to a second position to secure the wireless electrode assembly into the inner wall of the heart chamber.

  • Publication number: 20070067023
    Abstract: A tether guided bifurcated stent having a generally tubular main body extending along a longitudinal axis connected to a side branch assembly. Both the main stent body and the side branch assembly are capable of forming an unexpanded configuration and an expanded configuration. The bifurcation's expansion is facilitated by a force exerted by the tether. When the side branch assembly is expanded it forms a secondary tubular region defining a generally tubular shape extending at an angle to the longitudinal axis of the main tubular body.

  • Publication number: 20060149356
    Abstract: A radially expandable stent comprising a plurality of spaced band-like elements and intersecting links is disclosed. The band-like elements have a generally serpentine configuration to provide continuous waves of generally sinusoidal character to each band-like element. The waves are characterized by a plurality of peaks and troughs taking a generally longitudinal direction along the cylinder such that the waves in the band-like elements open as the stent is expanded from a first diameter to a second diameter. The intersecting links are substantially U-shaped and terminate in first and second shanks. The first shank of a link emanates from a region between a peak and trough on a band-like element and the second shank of the link emanates from a region between a peak and trough on an adjacent band-like element.

  • Publication number: 20050251248
    Abstract: A medical device such as a coronary stent is provided that can be visualized in-vivo while further aiding in the prevention of restenosis. The medical device comprises a core having a first layer disposed thereon. The first layer is made from a material that is radio-opaque so that the medical device may be visualized in-vivo. An outer layer is disposed onto and surrounds at least a portion of the first layer to provide a barrier layer between the radio-opaque inner layer and blood and/or tissue disposed within the patient's vessel. The outer surface of the outer layer may include a textured surface of micro-pores, grooves, cross-hatched lines to receive a therapeutic agent. Drugs and treatments which utilize anti-thombogenic agents, and anti-proliferation agents may be readily deployed from the textured outer surface of the outer layer of the medical device.

  • Publication number: 20050182480
    Abstract: In one embodiment of the invention, a stent may be provided comprising a first undulating band comprising a series of alternating first peaks and first troughs and a second undulating band comprising a series of alternating second peaks and second troughs. The first undulating band has a first wavelength and a first amplitude and the second undulating band has a second wavelength and a second amplitude where the second amplitude is different from the first amplitude and the second wavelength is different from the first wavelength. A plurality of longitudinally oriented first connectors extend between the first peaks and second peaks.
