摘要:
Single-use electrical leads for a nerve stimulator include a status flag element such as a fuse, which is deliberately blown after use of the leads has begun to indicate that the leads are not to be reused. The nerve stimulator has a “test mode” that determines a current value for treatment, and a “therapy mode” that administers treatment with the chosen current value. If the fuse in the electrical leads is blown, then the stimulator assumes that the leads have already been used and does not enter therapy mode. If the fuse in the electrical leads is intact, then the stimulator assumes that the leads are as yet unused, and allows the user to enter either test mode or therapy mode. The fuse is deliberately blown after a particular amount of time spent in therapy mode. After the fuse is blown, the user may still complete the therapy mode.

An introducer (10) for facilitating the injection of a bulking agent into the urinary sphincter of a patient comprises a rigid tubular member (12) having a closed distal end (16), an open proximal end (14) and a lumen (18) extending therebetween. The tubular member has an aperture (20) in a sidewall thereof leading to the lumen, the aperture being a known predetermined distance from the closed distal end. Integrally formed with the cylindrical tube is a flared wall structure (22) in the shape of a hollow cone. Formed obliquely through the wall of the cone are a plurality of regularly spaced bores (26) that exit the cylindrical tubular portion, a fixed, predetermined distance from the aforementioned aperture. By inserting the instrument into the urethra until urine flow is detected through the lumen of the guide, and then withdrawing the instrument carefully until urine flow just ceases, when an injection needle of a predetermined length is inserted into the oblique bore, the sharpened tip of the injection needle will be appropriately positioned for depositing the bulking agent in a way to augment tissue surrounding the urinary sphincter.

Novel principles for treating urological and gastric fluid reflux disorders are disclosed involving the injection of textured micro particles (30) wherein the textured micro particles having a combination of average unidimensional particle size range and average particle texture cooperate substantially to prevent loss of the micro particles from any injection site (31).

An electro-nerve stimulation apparatus includes a pulse generator (12), first and second electrically conductive, insulated lead wires (14, 16), an electrically conductive transcutaneous electrode (18) and electrically conductive percutaneous needle electrode (20). The lead wire set includes a single-use mechanism (44) adapted to effectively discourage reuse of the electrodes.
摘要:
Single-use electrical leads for a nerve stimulator are disclosed. The leads include a status flag element such as a fuse, which is deliberately blown after use of the leads has begun to indicate that the leads are not to be reused. The nerve stimulator has a 'test mode' that determines a current value for treatment, and a 'therapy mode' that administers treatment with the chosen current value. If the fuse in the electrical leads is blown (not conducting), then the stimulator assumes that the leads have already been used and does not enter therapy mode, and optionally may not enter test mode. If the fuse in the electrical leads is intact (conducting), or not blown, then the stimulator assumes that the leads are as yet unused, and allows the user to enter either test mode or therapy mode. The fuse is deliberately blown after a particular amount of time spent in therapy mode. After the fuse is blown, the user may still complete the therapy mode, even though the fuse is non-conducting, although the user may not initiate another therapy mode (and optionally may not initiate another test mode) using the blown leads. Preferably the fuse is electrically isolated from the leads that contact the patient.
摘要:
An implantable neuromodulation system and method of treating a patient through neuromodulation of a patient's body tissue. The neuromodulation system includes a portable transmitter and an implantable receiver. The implantable receiver includes one or more electrodes disposed on the distal end of one or more elongated, flexible insulated leads. The transmitter is programmable with a treatment protocol to cause the transmitter to generate a pulsed, alternating magnetic field in accordance with the treatment protocol. When the transmitter is placed in close proximity to the receiver, the alternating magnetic field pulses generated by the transmitter cause the receiver to operably generate stimulating pulses delivered via the electrode(s) to the targeted tissue of the patient.
