Problems solved by technology

Another disadvantage of some existing PNT technologies is that it can be difficult to manipulate, remember, and / or work around the electrodes, especially when using multiple electrodes simultaneously on a relatively small portion of the patient's body

Embodiment Construction

[0061] Transcutaneous electrotherapy systems, like PNT systems, send electrical current to the patient's tissue area through electrodes that pierce the skin overlying the tissue. The current is usually generated by a control unit external to the patient and typically has specific waveform characteristics like frequency, amplitude and pulse width. Depending on the treatment or therapy being performed, there may be one electrode comprising a cathode and an anode, or there may be multiple electrodes with at least one serving as the cathode and at least one serving as the anode.

[0062] The electrodes have sharp tips to facilitate insertion through the patient's skin and to increase local current density during treatment. Once inserted into the skin, the sharp tip may be exposed to pathogens, microorganisms, toxins, etc. within the patient's tissue and / or blood. After the electrodes are removed from the patient's tissue, the caregiver or other persons present may be accidentally...

Abstract

Methods and apparatuses for deploying percutaneous probes. An apparatus in accordance with one embodiment of the invention includes a housing (4) and a percutaneous probe having a sharp end (2) and positioned within the housing (4). The percutaneous probe is movable relative to the housing between a stowed position and at least one of a first deployed position and a second deployed position. The percutaneous probe (1) can project from the housing through aperture (5) by a first distance when in the first deployed position and a second distance greater than the first distance when in the second deployed position. A depth control device can operatively couple to the percutaneous probe and can have a first configuration to allow the percutaneous probe to be moved to the first deployed position and a second configuration to allow the percutaneous probe to be moved to the second deployed position.

Description

[0001] References to related applications [0002] This application claims priority to US Provisional Patent Application Serial No. 60 / 433,823 filed December 16, 2002, the disclosure of which is hereby incorporated by reference in its entirety into this disclosure. technical field [0003] The present invention relates to methods and apparatus for percutaneous application, including methods and apparatus for controlling the depth to which a percutaneous probe is deployed. Background technique [0004] In medicine, electrotherapy has long been used to treat pain and other conditions. For example, transcutaneous electrical nerve stimulation (TENS) systems send electrical energy through electrode patches placed on the surface of a patient's skin to treat pain in the tissue underlying and surrounding the patch site. However, the efficacy of TENS systems for pain relief is questionable at best. [0005] More recently, techniques for placing electrodes through the patient's skin...
