  • Patent number: 9446235
    Abstract: In some examples, relatively low frequency (e.g., less than about 50 Hertz) electrical stimulation therapy is delivered to a target tissue site proximate to one or more of the T9, T10, T11, T12, L1, L2, or L3 (“T9-L3”) spinal nerves of a patient to manage a pelvic floor disorder, such as urinary retention, fecal retention, or both. The relatively low frequency electrical stimulation therapy is configured to excite the one or more of the T9-L3 spinal nerves, which may generate an activating response from the patient related to voiding and help promote voiding by the patient. For example, the low frequency electrical stimulation may be configured to help improve the patient's pelvic sensations, which may help the patient better control urination.

  • Patent number: 9433790
    Abstract: In response to input from a patient who is being treated by a sacral nerve stimulation therapy, an electronic diary is generated that includes a plurality of voiding responses of the patient over a period of time. The sacral nerve stimulation therapy includes electrical pulses delivered to the patient according to a first stimulation program and via a first subset of electrode contacts on a lead that is implanted in the patient. The lead has a plurality of electrode contacts that include the first subset. Based on the voiding responses in the electronic diary, a loss of efficacy of the sacral nerve stimulation therapy is detected. The sacral nerve stimulation therapy is automatically adjusted in response to the detected loss of efficacy. The automatically adjustment of the sacral nerve stimulation therapy may include either a program-based sweep or a contact-based sweep.

  • Patent number: 9173678
    Abstract: The disclosure is directed to a method and tool for implanting a stimulation lead or other medical device adjacent a pudendal nerve. The tool includes a shaped needle that enters a patient and passes through an obturator foramen passage in a pelvis. A physician places a tip of the tool at the pudendal nerve and performs test stimulation to confirm an effective stimulation location. A shape memory cannula initially covering the needle remains at the pudendal nerve when the physician removes the tool. The cannula deforms to follow the curve of the pudendal nerve once the needle is removed, and a lead is inserted into the cannula and secured at the pudendal nerve placement site. This method may provide an easier and more consistent procedure for implanting the stimulation lead near the pudendal nerve.

  • Patent number: 9168004
    Abstract: Cardiac catheterization is carried out by memorizing a designation of a contact state between an electrode of the probe and the heart wall as one of an in-contact state and an out-of-contact state, and making a series of determinations of an impedance phase angle of an electrical current passing through the electrode and another electrode, identifying maximum and minimum phase angles in the series, and defining a binary classifier adaptively as midway between the extremes. A test value is compared to the classifier as adjusted by a hysteresis factor, and a change in the contact state is reported when the test value exceeds or falls below the adjusted classifier.

  • Patent number: 9149627
    Abstract: Kits provide management of implantable lead extensions being implanted by providing a kit body with features that retain the extension in a configuration, with amounts being removed as needed during the implantation procedure. The kit can be present within a sterile field, and the kit body features may be arranged so that a length of a path that the extension forms is approximately equal to a length of the extension needed for the tunnel. The kit body may include features that allow the connectors of the extension as well as implantation tools to be retained within the kit body while being easily accessed when needed during the procedure. The kit may be coupled to the patient during the trial period, as the extension may have an implanted distal connector while having a proximal connector coupled to an external stimulator and while being retained on the kit body.
