  • Patent number: 10265137
    Abstract: Systems, methods, and devices are provided for assisting or performing guided interventional procedures using custom templates. The system uses pre-procedure scans of a patient's anatomy to identify targets and critical structures. A template is then manufactured containing guide elements. During a procedure, the template may be aligned to the patient and instruments passed though the guide elements and into various targets. The template may be aligned using one or more of, for example, a position sensing system or a live imaging modality to register the patient to the template. The system makes optional use of devices designed to immobilize or track an organ during therapy.

  • Patent number: 10252068
    Abstract: An implantable medical device having a sensing module and a control module is configured to receive a cardiac electrical signal and sense events from the cardiac electrical signal received via electrodes carried by a medical electrical lead when the medical electrical lead is coupled to the implantable medical device. The control module coupled is configured to detect non-sustained tachyarrhythmia (NST) episodes based on sensed event intervals and determine if the sensed event intervals during the detected NST episode satisfy oversensing criteria. If the oversensing criteria are satisfied, the control module determines whether the detected NST episode satisfies non-lead related oversensing criteria and withholds a lead integrity alert when the NST episode meeting the oversensing criteria is determined to satisfy non-lead related oversensing criteria.

  • Patent number: 10238879
    Abstract: Implantable medical devices including interconnections having strain-relief structure. The interconnections can take the form of flexible circuits. Strain relief gaps and shapes are integrated in the interconnections to relieve forces in each of three dimensions. In some examples, the region of an interconnection which couples with a component of the implantable medical device is separated by a strain relief gap from a connection to a second component and/or a location where the flex bends around a corner.

  • Patent number: 10238311
    Abstract: Devices and methods are disclosed which relate to the detection of cardiovascular efficiency and risk of disease. The rate of volumetric change of the heart can be determined by measuring the parallel conductance across electrodes attached to the heart. Measurements from a lumen would consider the total conductance. The rate of volumetric or lumen cross-section area change can then be compared to an average model to determine the health of a patient.

  • Patent number: 10213609
    Abstract: Devices, systems, and methods are disclosed for relaying information from a cardiac pacemaker to an external device. Logic on the pacemaker modulates a heartbeat clock of the pacemaker to encode information onto a blood pressure sequence by adding or subtracting a small subinterval to or from a pulse repetition interval of the pacemaker. A muscle stimulator beats the heart according to the modulated sequence. A monitoring device external to the body monitors the blood pressure to retrieve the encoded information, or message. The encoded information is then decoded to determine the information in the message. This information may concern the pacemaker as well as other devices within the body that communicate with the pacemaker such as blood monitors, etc. Since the message is conveyed via simple modulation of the heart beat intervals, no separate transmitter is required in the pacemaker which would otherwise increase cost and decrease battery life.
