  • Patent number: 10391321
    Abstract: A method of evaluating an implantation of a lead is disclosed. Via a graphical user interface of an electronic device, a visual representation of a sacrum of the patient and a lead that is implanted in the sacrum is displayed. The lead includes a plurality of electrode contacts. An evaluation is made as to how well the lead has been implanted in the sacrum based on the visual representation of the sacrum and the lead. The evaluating comprises: determining whether the lead is inserted in a predetermined region of the sacrum, determining how far a predetermined one of the electrode contacts is located from an edge of the sacrum, and determining a degree of curvature of the lead.

  • Patent number: 10238877
    Abstract: An anal electrode device is configured to measure a response of a patient to a stimulation pulse. The anal electrode device includes an elongated shaft that is configured to be at least partially inserted into an anal canal of the patient. A first sensory electrode is disposed on a first region of the shaft. The first sensory electrode is configured to measure a compound motor action potential (CMAP) from an internal sphincter of the patient while the shaft is partially inserted into the anal canal of the patient. A second sensory electrode is disposed on a second region of the shaft. The second sensory electrode is configured to measure the CMAP from an external sphincter of the patient while the shaft is partially inserted into the anal canal of the patient.

  • Patent number: 9889293
    Abstract: In various examples, an apparatus includes a stimulation lead including an elongate body including a distal end and a proximal end. At least one first electrode is disposed proximate the distal end of the elongate body and is configured to stimulate a first target nerve. At least one second electrode is disposed between the at least one first electrode and the proximal end of the elongate body and is configured to stimulate a second target nerve. At least one first fixation structure is disposed between the at least one second electrode and the proximal end of the elongate body. The at least one first fixation structure is configured to anchor the stimulation lead proximate the sacrum, wherein the at least one first fixation structure is located on the elongate body and spaced a first distance proximally along the elongate body from the at least one first electrode.
