Publication number: 20120035686Abstract: In general, the invention is directed to a system with a fail-safe mode for remote programming of medical devices, such as implantable medical devices (IMDs). During a remote programming session, an adverse event, such as a programming session failure, may prevent proper completion of a programming or result in improper programming due to data corruption or other factors. If a programming session is not completed correctly, the IMD is susceptible to improper operation, possibly exposing a patient to delivery of unnecessary or inappropriate therapies. A fail-safe mode reduces the likelihood of improper operation following a programming session failure. The fail-safe mode defines one or more fail-safe operations designed to preserve proper operation of the IMD. In some embodiments, the fail-safe operations include notifying a person concerning the failure of the programming session, modifying programming parameters within the implantable medical device, and delivering a therapy to a patient.Type: ApplicationFiled: October 20, 2011Publication date: February 9, 2012Inventors: Christopher M.

In various embodiments, a red event is an imminent life threatening event, a yellow event is a serious health-related condition that is not imminently life threatening, and a green event is an event that is neither an imminent life threatening event nor a serious health-related condition. Other aspects and embodiments are provided herein.Type: GrantFiled: December 18, 2002Date of Patent: October 25, 2011Assignee: Cardiac Pacemakers, Inc.Inventors: John Hatlestad, Jeffrey E.

Publication number: 20110257705Abstract: A control unit for an implantable medical device includes a housing and electronics within the housing. The electronics control an RF emission from the control unit. An antenna is pivotably connected to the housing. The antenna is movable between a stowed position where RF emission from the antenna is prevented and a deployed position where RF emission from the antenna is permitted. To use the external control unit to effect communication between an external control unit and an implanted medical device, the user places the external control unit within electronic communication range of the implanted medical device. The control unit antenna is moved from the stowed position to a deployed position where RF emission from the antenna is permitted. RF waves are emitted from the antenna to establish communication between the external control unit and the implanted medical device.Type: ApplicationFiled: June 8, 2011Publication date: October 20, 2011Applicant: CODMAN NEURO SCIENCES SARLInventors: Alec Ginggen, Thierry Pipoz

Patent number: 8036747Abstract: A system and method for rapidly switching stimulation parameters of a Spinal Cord Stimulation (SCS) system increases the number of stimulation parameter sets that may be tested during a fitting procedure, or alternatively, reduces the time required for the fitting procedure. The switching method comprises selecting a new stimulation parameter set, and setting the initial stimulation levels to levels at or just below an estimated perception threshold of the patient. The estimated perception level is based on previous stimulation results. The stimulation level is then increased to determine a minimum stimulation level for effective stimulation, and/or an optimal stimulation level, and/or a maximum stimulation level, based on patient perception.Type: GrantFiled: July 21, 2009Date of Patent: October 11, 2011Assignee: Boston Scientific Neuromodulation CorporationInventors: James R.

Patent number: 8032229Abstract: Systems and methods for adjusting a therapy delivered to a patient include detecting a value of at least one sensed patient parameter and adjusting a therapy parameter value to accommodate different patient parameter values. A data structure including a plurality of patient parameter values and associated therapy parameter values may be stored within a medical device or a programming device. Upon detecting a patient parameter value, an associated therapy parameter value from the data structure may be selected. If no therapy parameter value is associated with the detected patient parameter value, an intermediate therapy parameter value may be generated by interpolating between the most recently implemented therapy parameter value and a stored therapy parameter value. In some embodiments, the rate of shifting between parameters of two stored or interpolated therapy parameter values may be based on the rate of change of the patient parameter value over time.Type: GrantFiled: June 15, 2010Date of Patent: October 4, 2011Assignee: Medtronic, Inc.Inventors: Martin T. Gerber, John C. Rondoni

Patent number: 8032226Abstract: Some embodiments of an infusion pump system can include a controller device that communicates with a pump device, the pump device having a memory device. The controller device can be configured to record controller-related data, such as user profile data on the memory device of the pump device. This user profile data that is stored in the memory of the pump device can serves as a data backup system that permits the user to program a new controller device in a situation where the original controller device is lost or damaged. In addition or in the alternative, the controller device can be configured to receive controller-related data, such as software update programs or backup controller data, from the memory device of the pump device.Type: GrantFiled: September 7, 2007Date of Patent: October 4, 2011Assignee: Asante Solutions, Inc.Inventors: Steve Miller, John W.

Publication number: 20110238135Abstract: An improved implantable pulse generator (IPG) containing graceful shutdown circuitry is disclosed. A magnet sensor senses the presence of an emergency shutdown magnet. Output of the magnet sensor is conditioned by a signal conditioning circuit. Output of the signal conditioning circuit is delayed by a delay element before being fed to a power cut-off switch, which cuts-off power to the IPG circuitry. An interrupt signal is routed from before the delay element to the IPG processor as an indicator of imminent shutdown. The processor launches shutdown routine that carries out shutdown operations such as logging the emergency shutdown event, saving and closing open files, saving data from volatile memory to non-volatile memory, etc., before the power cut-off switch is activated upon elapsing of delay provided by the delay element. The magnet sensor, signal conditioning circuit, and delay element are powered separately from the rest of the circuitry of the IPG.Type: ApplicationFiled: February 18, 2011Publication date: September 29, 2011Applicant: Boston Scientific Neuromodulation CorporationInventors: Goran Marnfeldt, Jordi Parramon
