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.

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.

Abstract: Devices and methods for centering an intravascular filter within a blood vessel are disclosed. A filter system in accordance with an exemplary embodiment of the present invention may include an intravascular filter, a filter sheath adapted to contain the intravascular filter, and a centering member adapted to assume a preset shape when deployed within a blood vessel. The centering member may comprise an elongated wire having a hoop section adapted to radially expand against the inner wall of the blood vessel when deployed. In some embodiments, multiple centering members can be employed to facilitate centering of both the intravascular filter and the filter sheath within the blood vessel, if desired.
