An implantable electrical lead for use in the stimulation of biological tissues is provided. The lead has at least one surface electrode comprising a distal end and a proximal end. The at least one surface electrode is placed on the surface of tissue at an implant site, and at least one anchoring element with a distal end and a proximal end for holding the electrode at a desired position on the implant site is placed above the electrode at the implant site.

Surface electrodes

The present invention relates generally to systems and methods for measuring an analyte in a host. More particularly, the present invention relates to systems and methods for transcutaneous measurement of glucose in a host.

Transcutaneous analyte sensor

Systems and methods for processing sensor analyte data are disclosed, including initiating calibration, updating calibration, evaluating clinical acceptability of reference and sensor analyte data, and evaluating the quality of sensor calibration. The sensor can be calibrated using a calibration set of one or more matched sensor and reference analyte data pairs. Reference data resulting from benchtop testing an analyte sensor prior to its insertion can be used to provide initial calibration of the sensor data. Reference data from a short term continuous analyte sensor implanted in a user can be used to initially calibrate or update sensor data from a long term continuous analyte sensor.

System and methods for processing analyte sensor data for sensor calibration

Systems and methods for treating a gastrointestinal condition of a patient includes minimally invasively implanting a modular stimulator system in a patient's treatment site. The modular stimulator system comprises a microstimulator module, a small power source module and a macrostimulator module that are detachably attachable to each other. For the first phase of treatment, the microstimulator module and power source are implanted with a stimulating electrode proximate a target tissue. Electrical stimulation is provided for a short period of time and treatment efficacy is evaluated through clinical results and patient reporting. If therapy is not effective, stimulation parameters can be changed and/or the implantation site can be moved. If therapy is effective, portions of the microstimulator module and/or small power source are replaced with the macrostimulator module for long term therapy of the second phase of treatment.

The present specification discloses devices and methodologies for the treatment of transient lower esophageal sphincter relaxations (tLESRs). Individuals with tLESRs may be treated by implanting a stimulation device within the patient's lower esophageal sphincter and applying electrical stimulation to the patient's lower esophageal sphincter, in accordance with certain predefined protocols. The presently disclosed devices have a simplified design because they do not require sensing systems capable of sensing when a person is engaged in a wet swallow and have improved energy storage requirements.

Device and implantation system for electrical stimulation of biological systems

Systems and methods for dynamically and intelligently estimating analyte data from a continuous analyte sensor, including receiving a data stream, selecting one of a plurality of algorithms, and employing the selected algorithm to estimate analyte values. Additional data processing includes evaluating the selected estimative algorithms, analyzing a variation of the estimated analyte values based on statistical, clinical, or physiological parameters, comparing the estimated analyte values with corresponding measure analyte values, and providing output to a user. Estimation can be used to compensate for time lag, match sensor data with corresponding reference data, warn of upcoming clinical risk, replace erroneous sensor data signals, and provide more timely analyte information encourage proactive behavior and preempt clinical risk.

Signal processing for continuous analyte sensor

Systems and methods for minimizing or eliminating transient non-glucose related signal noise due to non-glucose rate limiting phenomenon such as ischemia, pH changes, temperatures changes, and the like. The system monitors a data stream from a glucose sensor and detects signal artifacts that have higher amplitude than electronic or diffusion-related system noise. The system replaces some or the entire data stream continually or intermittently including signal estimation methods that particularly address transient signal artifacts. The system is also capable of detecting the severity of the signal artifacts and selectively applying one or more signal estimation algorithm factors responsive to the severity of the signal artifacts, which includes selectively applying distinct sets of parameters to a signal estimation algorithm or selectively applying distinct signal estimation algorithms.

The present specification discloses devices and methodologies for the treatment of GERD. Individuals with GERD may be treated by implanting a stimulation device within the patient's lower esophageal sphincter and applying electrical stimulation to the patient's lower esophageal sphincter, in accordance with certain predefined protocols. The presently disclosed devices have a simplified design because they do not require sensing systems capable of sensing when a person is engaged in a wet swallow, have improved energy storage requirements, enable improved LES function while concurrently delivering additional health benefits, and enable improved LES function post stimulation termination.

Analyte sensor

A method of laparoscopically implanting an electrically stimulating lead proximate the lower esophageal sphincter (LES) of a patient includes delivering the lead through a port of a laparoscope inserted into the abdominal cavity of the patient through an incision in the abdominal wall. The stimulating electrode is implanted in or proximate the muscularis layer of the lower esophageal wall to treat esophageal reflux disease (GERD). The lead includes a needle and suture at its distal end for pulling the electrode into the muscular wall of the LES. Clips are applied to the suture attached to the distal end of the lead to prevent retrograde movement of the electrode. The lead also includes an anchoring member for anchoring the portion of the lead proximal to the electrode. The method and lead used with the method allow the surgeon to work within the confined anatomy present at the gastroesophageal junction and prevents backwards movement and dislodgment of the electrode. The implantation procedure can be combined with a hiatal hernia repair to repair the hernia and prevent recurrence of a hiatal hernia.

Methods for electrically stimulating body tissues to improve function or reduce symptoms provide an electrical stimulation system having two or more electrodes that are capable of being switched independently from a hyperpolarizing (depolarizing) state to a hypopolarizing state. Multiple combinations of hyperpolarizing electrodes and hypopolarizing electrodes are created by polarity switching to determine a polarity configuration having the best performance as determined by symptom reporting and clinical diagnostic tests. Polarity switching is triggered manually or is programmed to be switched automatically. Determining the configuration providing electrical stimulation resulting in the greatest benefit allows the system to be operated with one or more electrodes in a hypopolarizing state, thereby reducing energy requirements, tissue tolerance, and tissue fatigue.
