Abstract: Thermal drawing processes can be used to make multifunctional, high-resolution neural probes for neural recording and stimulation. An exemplary neural probe may include one or more conductive fibers or microelectrodes coated with two or more layers of insulating material, at least one of which is partially etched to expose a tip at the neural probe's distal end. The conductive fibers conduct electrical signals (e.g., neural spikes or electrical stimulation) between the tip and the neural probe's proximal end. Optional optical and fluidic waveguides may guide light and fluid, respectively, between the tip and the proximal end. A neural probe may be flexible enough for long-term (chronic) implantation in neural tissue (e.g., the brain) without excessive tissue damage, even during movement of the brain in the skull. The probe may be made from biocompatible materials, such as insulating and conductive polymers, that have negligible (insignificant) interaction with the surrounding tissue.

Abstract: In order to determine the state of a muscle between a normal non-tired state, a tired state and a passive involuntary tension state, a signal from the muscle is recorded at rest by using an electrode arrangement, where an earth body may prevent the electrodes from picking up signals beyond the extent of the earth body. The frequency content of the signal is determined by spectral analysis, e.g. by computing a moment of the spectrum. A normal frequency content indicates a non-tired muscle state, whereas a low and a high frequency content indicate a tired and a passive involuntary tension muscle state. A mapping is used to improve accuracy of state determination, e.g. with a reference database.

Abstract: An apparatus for deflecting a distal portion of a catheter, a sheath, a medical device, or other flexible elongate member may generally include a handle portion, a pair of adjusting knobs, and deflection wires. The adjusting knobs may be rotatably coupled to the handle portion and operably coupled to the deflection wires.

Abstract: Physiological monitoring can be provided through a wearable monitor that includes a flexible extended wear electrode patch and a removable reusable monitor recorder. A pair of flexile wires is interlaced or sewn into a flexible backing, serving as electrode signal pickup and electrode circuit traces. The wearable monitor sits centrally on the patient's chest along the sternum, which significantly improves the ability to sense cutaneously cardiac electric signals, particularly those generated by the atrium. The electrode patch is shaped to fit comfortably and conformal to the contours of the chest approximately centered on the sternal midline. To counter the dislodgment due to compressional and torsional forces, non-irritating adhesive is provided on the underside, or contact, surface of the electrode patch, but only on the distal and proximal ends. Interlacing the flexile wires into the flexile backing also provides structural support and malleability against compressional, tensile and torsional forces.

Abstract: Physiological monitoring can be provided through a lightweight wearable monitor that includes two components, a flexible extended wear electrode patch and a reusable monitor recorder that removably snaps into a receptacle on the electrode patch. The wearable monitor sits centrally on the patient's chest along the sternum oriented top-to-bottom. The placement of the wearable monitor in a location at the sternal midline, with its unique narrow “hourglass”-like shape, significantly improves the ability of the wearable monitor to cutaneously sense cardiac electrical potential signals, particularly the P-wave and the QRS interval signals indicating ventricular activity in the ECG waveforms. In particular, the ECG electrodes on the electrode patch are tailored to be positioned axially along the midline of the sternum for capturing action potential propagation in an orientation that corresponds to the aVF lead used in a conventional 12-lead ECG that is used to sense positive or upright P-waves.
