Abstract: Neurostimulation assemblies, systems, and methods make possible the providing of short-term therapy or diagnostic testing by providing electrical connections between muscles and/or nerves inside the body and stimulus generators and/or recording instruments mounted on the surface of the skin or carried outside the body. The assembly affords maximum patient mobility and comfort through differentiated components having minimal profiles and connected by way of detachable and adjustable connections.

Abstract: The guide wire invention relates to improvements in magnetically navigable medical guide wires for enabling, in addition to magnetic navigation, conventional navigation without the use of a magnetic field. The distal portion of the guide wire may be navigated by either manually applying an axial rotation to the guide wire or by applying a magnetic field to modify the curvature of the distal portion to access small branch vessels in a subject body. The distal portion of the guide wire can also be straightened or aligned with the longitudinal axis of the guide wire by applying a magnetic field that straightens the bent section in the direction of the longitudinal axis, which enables the guide wire to push through a lesion.

Abstract: A guide wire for magnetically navigating a medical device through in a subject's body comprising an elongate wire having a proximal and distal end, a portion adjacent the distal end that is more flexible than the more proximal portions of the elongate wire, and a first magnetically responsive element on the distal end of the elongate wire. The guide wire further comprises one or more magnetically responsive elements spaced apart from the first magnetically responsive element and disposed on the more flexible portion of the elongate wire. The guide wire provides for bending or deflecting the distal end of the stent, to provide easier navigation of the distal end of the guide wire and the stent through the vasculature of a subject body.

Abstract: A balloon catheter comprising an elongate tube having a proximal end and a distal end, and a lumen therebetween, and a balloon at the distal end of the tube, in fluid communication with the lumen. A magnetically responsive element at the distal end of the device sized and shaped to orient the distal end of the device in an operating region in a subject upon the application of a magnetic field from an external source magnet.

Abstract: Atherectomy devices are guided by and manipulated by externally applied magnetic fields to treat total or partial occlusions of a patient's vasculature.
