摘要:
A medical patch having a multi-piece bottom liner including a central liner sequentially removable independently of two outer perimeter liners. The multi-piece liner covering two adhesives of different peel force. Removal of the central liner exposes a first temporary/repositionable adhesive. Once properly positioned, the outer perimeter liners are removed to expose a second stronger adhesive. A foam cushioning layer is disposed beneath and extends beyond a footprint of every printed circuit board to prevent skin irritation. The medical patch may be designed specifically for stimulation of the sacral (S3 foramen) spinal nerve without the use of a separate mechanical placement tool or assistance by another.

摘要:
An implantable urodynamic system includes an implantable first device deployable in a patient's bladder, an implantable second device deployable in a patient's vaginal canal, and a data acquisition and analysis module or processing unit external to the body of the patient. The first device includes a magnet and an inductive coil, and the second device includes a magnet, an inductive coil and a battery. When deployed in the patient's body, attraction between the magnets maintains the two devices in close proximity to one another to effect an inductive coupling between the coils so that the first device may be powered by the battery of the second device. The urodynamic system is intended to facilitate measurement, collection, and wireless transmission of real-time, or near real-time, data (bladder pressure, abdominal pressure, and temperature) from an ambulatory patient. This data is of value in diagnosing a number of abnormal bladder conditions, such as infection, overactive bladder, bladder spasms, and the like.

摘要:
A method and associated stimulation device for ensuring firing of an action potential in an intended physiological target activated by a stimulus pulse generated by an electrode of a non-invasive surface based stimulation device irrespective of skin-to-electrode impedance by: (i) increasing internal impedance of the stimulation device so as to widen a Chronaxie time period thereby ensuring firing of the action potential of the intended physiological target irrespective of the skin-to-electrode impedance; and/or (ii) generating a stimulation waveform that optimizes a non-zero average current (e.g., non-zero slope of the envelope of the stimulation waveform) during preferably substantially the entire current decay of the stimulus pulse.
摘要:
A method for stimulating a predetermined body part such as a nerve using a stimulation device including an external non-implantable transmitting device powered by a power source and generating an electrical waveform signal. A surface electrode applies the generated electrical waveform signal transcutaneously. An implantable piezoelectric element receives the applied electrical waveform signal generated transcutaneously and, in turn, causes mechanical deformation resulting in mechanical vibration of the implantable piezoelectric element sufficient to stimulate the predetermined body part. The electrical waveform signal may be either a high frequency continuous waveform or high frequency burst packets.

摘要:
A system for stimulating a nerve or nerves in a patient includes an electrode patch having an array of equally spaced concentric electrodes each having a central cathode and a concentrically surrounding anode. The electrode array patch is used to determine the location of the nerve or nerves to be stimulated by electrical pulses. Once the location of the nerve is determined, a concentric electrode patch having a central cathode and a concentrically surrounding anode is positioned at the optimal location on the patient's skin to effect neurostimulation. The concentric electrode patch may be removably affixed to the patient's skin by adhesive or magnets.
