Patent number: 9956411Abstract: A current generation architecture for an implantable stimulator device such as an Implantable Pulse Generator (IPG) is disclosed. Current source and sink circuitry are both divided into coarse and fine portions, which respectively can provide coarse and fine current resolutions to a specified electrode on the IPG. The coarse portion is distributed across all of the electrodes and so can source or sink current to any of the electrodes. The coarse portion is divided into a plurality of stages, each of which is capable via an associated switch bank of sourcing or sinking a coarse amount of current to or from any one of the electrodes on the device. The fine portion of the current generation circuit preferably includes source and sink circuitry dedicated to each of the electrode on the device, which can comprise digital-to-analog current converters (DACs).Type: GrantFiled: April 6, 2016Date of Patent: May 1, 2018Assignee: Boston Scientific Neuromodulation CorporationInventors: Jordi Parramon, David K.

Patent number: 9956418Abstract: The disclosure provides a system that displays graphical representations of posture zones associated with posture states of a patient, on a display device communicatively coupled to a medical device. The medical device is configured to deliver therapy to the patient based on detected posture states of the patient, where the detected posture state is based on the posture zones. The display device may allow a user to manipulate the graphical representations of the posture zones, including changing the size of the posture zones. Additionally, the display device may allow a user to change transition times associated with transitions between posture states, and displaying an indication of the changed transition time by highlighting the two graphical representations of the posture zones corresponding to the posture states associated with the changed transition time.Type: GrantFiled: January 6, 2011Date of Patent: May 1, 2018Assignee: Medtronic, Inc.Inventors: Jon P.

Patent number: 9950184Abstract: A wearable cardiac defibrillator (“WCD”) system may include a support structure that a patient can wear, an energy storage module that can store an electrical charge, and a discharge circuit that can discharge the electrical charge through the patient so as to shock him or her, while the patient is wearing the support structure. Embodiments may actively take into account bystanders, both to protect them from an inadvertent shock, and also to enlist their help. In some embodiments, the WCD system includes a speaker system, a memory and a proximity detector. Prompts have been stored in the memory. In case of an emergency, upon inferring that no bystander is nearby, the speaker system may transmit a sound at a higher intensity than otherwise, hoping to attract attention.Type: GrantFiled: November 28, 2016Date of Patent: April 24, 2018Assignee: WEST AFFUM HOLDINGS CORP.Inventors: Joseph L.

Patent number: 9931502Abstract: Disclosed herein are current output architectures for implantable stimulator devices. Current source and sink circuitry is divided into a plurality of stages, each of which is capable via an associated switch bank of sourcing or sinking an amount of current to or from any one of the electrodes of the device. The current source circuitry is distinct from the current sink circuitry, and the two share no common circuit nodes prior to connection to the electrodes. In other words, the current source circuitry and the current sink circuitry do not share a common node other than the electrodes. Each stage is preferably formed of a current mirror for receiving a reference current and outputting a scaled version of current to that stage's switch bank. The scalar at each stage can be set by wiring a desired number of output transistors in parallel.Type: GrantFiled: April 6, 2016Date of Patent: April 3, 2018Assignee: Boston Scientific Neuromodulation CorporationInventors: Yuping He, David K.

Patent number: 9907959Abstract: The disclosure describes techniques for modifying an electrical stimulation or another type of therapy provided to a patient by a medical device. The therapy modification may be based on a posture and/or activity state of a patient that is detected by an IMD, such as a change in a detected posture state occupied by the patient. Different therapy modifications may be applied for different changes in detected posture state. An IMD may modify therapy based on a transition from one posture state to another posture state. The IMD may determine a posture state of the patient for use in controlling therapy adjustments and/or other aspects of the system. In some examples, when the patient's movement and/or activity velocity exceeds a velocity threshold, a previously-determined stable posture state of the patient may be used to control therapy rather than a current posture state of the patient, which may be transient.Type: GrantFiled: April 12, 2012Date of Patent: March 6, 2018Assignee: Medtronic, Inc.Inventor: Dennis M. Skelton

Patent number: 9907891Abstract: The invention relates to a fluid pump or rotary cutter having at least one first element (9??, 10??) which can be brought from a transport state into an operating state by changing at least one mechanical property. Such a pump can, for example, be a blood pump for the medical, microinvasive area. The object of achieving a transition between the transport state and the operating state which is as comfortable as possible and in so doing leaving a freedom in the design of corresponding apparatus, in particular of a pump, which is as large as possible, is achieved using the means of the invention in that the first element at least partly comprises a material (24, 25, 26, 27) or can be filled with a material or material mixture which passes through a chemical reaction, in particular cross-linking, or a crystallization for transition into the operating state.Type: GrantFiled: November 16, 2015Date of Patent: March 6, 2018Assignee: ECP ENTWICKLUNGSGESELLSCHAFT MBHInventors: Petra Wiessler, Sven-Rene Friedel, Reiner Liebing, Sami Er, Henning Schlicht

Patent number: 9907971Abstract: Embodiments are directed to a medical device, such as a defibrillator, for use with an accessory capable of collecting a parameter of a patient. The medical device is capable of at least performing a basic functionality, an advanced functionality, and of defibrillating the patient. The medical device includes an energy storage module within a housing for storing an electrical charge that is to be delivered to the patient for the defibrillating. The medical device includes a processor structured to determine whether a data set received from the accessory confirms or not a preset authentication criterion about the accessory. Although when the accessory is coupled to the housing the medical device is capable of the defibrillating and the basic functionality, the medical device is capable of the advanced functionality only when the accessory is coupled to the housing and it is determined that the preset authentication criterion is confirmed. Embodiments also include methods of operation and a programmed solution.Type: GrantFiled: May 16, 2016Date of Patent: March 6, 2018Assignee: PHYSIO-CONTROL, INC.Inventor: Richard C. Nova

Patent number: 9888860Abstract: A map of cardiac activation wavefronts can be created from a plurality of mesh nodes, each of which is assigned a conduction velocity vector. Directed edges are defined to interconnect the mesh nodes, and weights are assigned to the directed edges, thereby creating a weighted directed conduction velocity graph. A user can select one or more points within the weighted directed conduction velocity graph (which do not necessarily correspond to nodes), and one or more cardiac activation wavefronts passing through these points can be identified using the weighted directed conduction velocity graph. The cardiac activation wavefronts can then be displayed on a graphical representation of the cardiac geometry.Type: GrantFiled: August 31, 2016Date of Patent: February 13, 2018Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Dongfeng Han, Valtino X.
