20090063977 | BODY REGION INDICATION - The invention is directed toward two-dimensional dynamic body image templates, and associated techniques, that allow a user to indicate regions of the human body. The body region indications may correspond to locations of injury, pain, treatment, discoloration, paresthesia, or the like. A user is presented with the body image templates and asked to indicate regions on the body templates that correspond to affected regions of a patient's body. The body image templates represent views of an external surface of a human body rotated about at least one axis. In exemplary embodiments, a user controls display of overlapping templates, which may allow the user to perceive rotation of a three-dimensional body surface. The user indicated regions from each of the displayed body image templates are stored in a body surface coordinate system, such that regions indicated via one template may be appropriately displayed on other templates. | 03-05-2009 |

20110022139 | Electrode having erectable lead - Disclosed is an electrode, such as an SCS paddle electrode, having a lead attached thereto along an interior portion of the electrode. The lead and electrode are configured such that the lead may be positioned generally coplanar with a top surface of the electrode, and may likewise be erected from such coplanar orientation up and away from the top surface of the electrode. Thus, the lead can maintain the typical configuration of emerging from the back end of the electrode, but because at least portions of the lead are not permanently bonded into the electrode paddle, the lead (when desired) can be pulled upward, with or without surrounding strain relief material, to emerge from the top surface of the paddle at an angle or curve to such top surface. This allows the base of the paddle to engage a bony opening, such as when the electrode is inserted into a patient's spine, skull, plane of fascia, etc. | 01-27-2011 |
20110022143 | Spinal cord stimulation lead anchor - Disclosed is an implantable anchor for anchoring a catheter, including (by way of non-limiting example) an implantable lead, such as may be used for spinal cord stimulation, to the body of a patient, along with a method for its use. The anchor comprises an elongate body have a central lumen extending through the body from its proximal end to its distal end, which central lumen is configured to snugly receive the catheter body. In addition to the central lumen, a second lumen is provided in the proximal end of the anchor and is configured to receive an injector so that adhesive may be injected into the anchor surrounding at least a portion of the catheter body. In doing so, the anchor may be fixed to the catheter body, such that when the anchor is sutured in place within the patient's body, migration of the catheter may be avoided. | 01-27-2011 |
20110029053 | Modular electrode and insertion tool - Disclosed is a modular system for providing electrical stimulation to a patient's body, in which a first modular electrode section has a contoured back end configured to engage with a contoured front end of another electrode section or a tool that may be used to place the first modular electrode section in the patient's body. The contours of the back end of the first modular electrode section and of the front end of the second electrode section or tool allow the two components to engage with one another so as to prevent their separation in the horizontal plane (i.e., the plane that contains the top surfaces of the two components). Additionally, in order to prohibit both the lateral and vertical separation of the two components, a lead extending from the first modular electrode is configured to engage keels on the top surface of the second electrode portion or tool, with such keels providing a snap-type attachment between the lead and the second electrode portion or tool, such that the two components may be joined together but easily separated from one another through the intentional separation of the lead from the keels on the second electrode portion or tool. With this construction, a surgeon may ensure that the two components remain connected to one another through the implantation process, and may likewise separate the components if and when desired to accommodate a particular application or clinical condition. | 02-03-2011 |
20110125221 | FAILSAFE PROGRAMMING OF IMPLANTABLE MEDICAL DEVICES - A watchdog unit receives stay-alive signals from a programming device during programming of an implantable medical device. The watchdog unit maintains a watchdog timer, and resets the timer upon receipt of each stay-alive signal. If the watchdog timer expires, the watchdog unit changes a mode of operation of the implantable device, e.g., places the implantable medical device into a known, safe state. For example, the watchdog unit may cause the implantable medical device to suspend delivery of therapy, perform a power-on reset, and/or recall a known, safe, therapy delivery program. | 05-26-2011 |

Programs and information received from a plurality of programming devices and for a plurality of patients may be stored in the database and analyzed by the server to provide responses to user queries made by clinicians via programming devices. | 07-28-2011 |
20110196455 | NEUROSTIMULATION THERAPY MANIPULATION - A user, such as a clinician or the patient, uses a control device to manipulate at least one neurostimulation parameter. A mapping system uses a calibrated map to map the directional output of the control device to values of at least one stimulation parameter to allow the user to intuitively control the value of the parameter. In some embodiments, where a stimulation device is used to deliver spinal cord stimulation (SCS) therapy for example, the user manipulates a parameter to effect the location and/or strength of paresthesia experienced by the patient. In exemplary embodiments, the parameter values are combinations of electrodes, and the mapping system selects electrode combinations based on the output of the control device such that a direction of movement of paresthesia experienced by the patient corresponds to a direction of manipulation of a directional controller of the control device. The mapping system may calibrate the map based on patient paresthesia information received from a user. | 08-11-2011 |
