  • Patent number: 10285614
    Abstract: An implantable cardiac system that includes an implantable cardiac pacemaker or leadless pacemaker (iLP) and a second device such as a subcutaneous implantable cardioverter-defibrillator (S-ICD). The pacemaker includes an R-spike amplifier that amplifies stimulated ventricle excitations or R-waves to increase R-wave to T-wave signal to noise ratio and to improve indirect detection of ventricular rhythm classification by the S-ICD. The S-ICD includes an electrode line for defibrillation, a sensing unit and a stimulation detection unit. The S-ICD records a subcutaneous electrocardiogram between shock electrode poles and provides potentially life-saving therapy based thereon. The system significantly increases the specificity and sensitivity of an S-ICD in combination with an implanted cardiac pacemaker or iLP having an R-spike amplifier.

  • Publication number: 20180272133
    Abstract: A device for neurostimulation includes a pulse generator for generating current having pulses and at least one first pair of electrodes connected to the pulse generator. The device provides a user-programmable therapy strength parameter configuration and at least two current parameter configurations for neurostimulation stored in the pulse generator. The current parameter configurations are controlled by the therapy strength configuration, at least one of the current parameter configurations is associated with a level of paresthesia sensation of a patient and at least one of the current parameter configurations is associated with a paresthesia-free therapy for the patient. The association between therapy strength parameter and current parameter configurations uniquely adjusts the current parameter configurations based on paresthesia or paresthesia-free intent, when neurostimulation is performed using parameter configurations.

  • Publication number: 20180071543
    Abstract: A system and method for installing/implanting a leadless implant can include a leadless implant with shortened tine-based anchors and an implantation tool with a modified tip. The tines can extend from a surface of the leadless implant and may include a preformed curve or other shape to enable the tine to hook into or grapple tissue. The implantation tool may be provided with a modified tip to assist with proper alignment, insertion, and anchoring of the shortened tines. A tip of the implantation tool can have a reduced inner diameter to cause the tine tips to be approximately normal to the surface of the tissue to which the implant is being anchored. Upon deployment of the leadless implant, the tines of the anchoring mechanism are appropriately aligned for proper insertion so that robust anchoring is achieved.
