5results about "Esophageal electrodes" patented technology

Electrical stimulation devices and associated systems and methods are disclosed herein. In some embodiments, the electrical stimulation device comprises an elongated member configured to be orally or nasally inserted into a patient's pharynx. The device may further include a conductive element carried by a distal portion of the elongated member and configured to deliver stimulation energy to nearby tissue. A stiffness of the elongated member may vary along its length to facilitate insertion of the elongated member through the nasopharyngeal junction and provide a restoring force necessary to hold the conductive element in apposition with tissue at the treatment site.

A medical device comprises a tube (12) having and at least one lumen, a flexible body (102) including a stimulation array (114) to provide an electrical charge for stimulating tissue, an electrical connection to electrically couple the stimulation array to a power source and positioned on the flexible body proximal to the stimulation array, and an electronic component positioned between the stimulation array (114) and the power source. The electronic component includes a memory and a processor configured to implement programmable code stored on the memory. The flexible body (102) is configured to cover at least a portion of the longitudinal length of the tube (12) such that the stimulation array (114) is disposed about an exterior of the tube.

A system and method of eliciting a swallowing reflex in a human subject. Stimulation signals are generated for eliciting a full swallowing reflex when applied to skin overlying a region of thyroid cartilage in the neck. The stimulation signals delivered via surface electrodes to the skin overlying at least the region of thyroid cartilage in the neck to elicit the full swallowing reflex in the human subject.

Example devices and techniques are disclosed for delivering neurostimulation therapy transesophageally. An example device includes stimulation circuitry configured to generate a transesophageal stimulation signal. The example device includes memory configured to store stimulation parameters that at least partially define the transesophageal stimulation signal and processing circuitry communicatively coupled to the memory, and the stimulation circuitry. The processing circuitry is configured to determine a maximum transesophageal stimulation amplitude value. The processing circuitry is configured to control the stimulation circuitry to generate the transesophageal stimulation signal based at least in part on at least one of the stimulation parameters or the maximum transesophageal stimulation amplitude such that an amplitude of the transesophageal stimulation signal does not exceed the maximum transesophageal stimulation amplitude.
