Abstract: A programming algorithm is disclosed to efficiently select stimulation parameters for a patient having a Deep Brain Stimulation (DBS) implant. The algorithm preferably first determines an optimal longitudinal position (Lopt) and amplitude (Iopt1) for stimulation along the lead. This occurs by the algorithm efficiently suggested various values for L and I at which stimulation can be tried on the patient and scored. Once Lopt is determined, the algorithm can also determine an optimal rotational angle (?opt) and amplitude (Iopt2) for stimulation around the lead at the optimized longitudinal position Lopt. This also occurs by the algorithm efficiently suggesting various values for ? and I at which stimulation can be tried on the patient and scored. Despite suggesting next L,I or ?,I values to test, the algorithm allows flexibility to allow a user to test any desired stimulation parameters beyond those suggested.

Abstract: Methods and systems for assisting a user to program stimulation parameters for an implantable pulse generator (IPG) are described. The IPG may be configured to provide electrical stimulation via a plurality of electrodes. The amount of stimulation current provided by each of the electrodes may be individually controlled. A graphical user interface (GUI) is provided for displaying an indication of the current to be delivered via each the electrodes. In some embodiments, the currents are expressed in terms of a total current to be delivered by the plurality of electrodes, and percentage values of that current to be delivered by each individual electrodes. If a user wishes to modify an amount of current amplitude to be delivered by a particular electrode, the described system is configured to update the total current and the percentage values for each of the electrodes based on the modification.

Abstract: Disclosed is a device that uses suture to close various layers of tissue quickly and precisely. The device and methods enhance the efficiency, consistency and cost-effectiveness of traditional hand-suturing without compromising cosmetic or wound healing outcomes. Adjustable instruments on either side of the device are applied to opposing sides of the desired layer of tissue to approximate the edges of the tissue to be closed. The user may control the delivery of a single stitch or a series of stitches at an adjustable interval to the desired layer of tissue. An instrument may perform the stitch or series of stitches as the operator guides the device along the tissue opening. Once the device has delivered the appropriate stitch(es), the user may remove excess suture material and release the tissue from the instruments on either side of the incision and the process may be repeated as necessary to close a wound.
