Abstract: Methods for data de-duplication and data augmentation are performed by systems and devices. A request for information is received over a network from a requestor by a host, and is provided to an information source for a response. The host retrieves first data from a data source associated with the request, and receives the response that includes second data associated with the request. The first and second data are aggregated by the host. The aggregated data is processed by the host to remove duplicate information/records. The aggregated data is processed by the host to augment eligible data fields to correct, supplement, and calculate the aggregated data through data augmentation. An updated response is then provided back to the requestor with augmented data tracking. Neural network models are also utilized by the host for data augmentation.

Abstract: A medical electrical lead includes a proximal insulation segment, a distal insulation segment, a conductor extending within the proximal and distal segments, and an electrode coupled to the conductor and disposed in proximity to a distal end of the distal insulation segment. A fixation element of the lead is coupled to a distal end of the proximal insulation segment and includes a wire wound in a helix, which extends distally from the proximal segment, over the distal insulation segment.

Abstract: An implantable medical lead configured for active fixation in the vasculature of a patient includes an elongated lead body having a central lumen and a distal tip. Disposed within the central lumen are a fixation helix and an elongated member, such as a lead coil, coupled to the fixation helix. The elongated member is adapted to rotate the fixation helix, thereby causing it to advance or retract within the central lumen of the lead body. The lead body includes a window along a portion of its length through which the fixation helix may be affixed to a blood vessel of the patient's vasculature.

Abstract: An implantable medical device that includes an elongated body having a proximal end and a distal end, a helical fixation member extending from the distal end of the elongated body, the helical fixation member including a distal tip for affixing the distal end of the elongated body at an implant site, and a tracking member extending from the distal end of the elongated body, through the helical fixation member and outward from the distal tip of the helical fixation member for tracking along an implant pathway during implantation of the implantable medical device.

Abstract: A medical electrical lead comprises an elongate conductor and a sheath extending over the conductor to form a rotating assembly.

Abstract: A distal tip coupled to a body of an implantable medical device includes a canted passageway extending distally from a lumen of the body and an opening terminating the passageway and positioned in proximity to a distal end of the distal tip; a helical fixation element coupled to an elongated member extending within the lumen of the body is adapted to deflect along the canted passageway of the distal tip. The elongated member is adapted to move the helical member through the passageway of the distal tip and out from the opening and to rotate the helical element thereby affixing the helical element into an implant site.

Abstract: A pre-formed j-shape stylet, slideably received within a lumen of a medical electrical lead, includes a proximal end, a distal end, a substantially straight distal segment extending from the distal end, a curved intermediate segment extending from the substantially straight distal segment, a substantially straight proximal segment extending from the curved intermediate segment toward the proximal end, and a taper zone extending within the curved intermediate segment.

Abstract: A connector sleeve includes a lumen adapted to receive a medical lead connector wherein a retention element engages a retention edge formed at a distal end of a connector element included on the lead connector. The connector sleeve further includes a contact element adapted to electrically engage the lead connector element within the lumen and an external conductive surface electrically coupled to the contact element and adapted for electrical engagement within the connector bore of an implantable medical device.
