Abstract: An apparatus comprises an input configured to receive electrocardiogram (ECG) data detected by a patient monitoring device, the ECG data containing a physiologic signal and one or more segments of noise within the ECG data. A scrubber comprises a plurality of scrubbing modules each configured to process the ECG data and noise in a manner differing from other scrubbing modules. The scrubber is configured to filter the one or more noise segments that overlap with the physiologic signal, and consolidate the ECG data to eliminate the one or more noise segments that are non-overlapping with the physiologic signal. An output is configured to output scrubbed ECG data.

Abstract: An apparatus, system, and method directed to detecting a physiological signal during discrete time separated detection windows, deriving one or more respiratory disturbance indices from the physiological signal, detecting a respiratory disturbance state in response to the one or more respiratory disturbance indices deviating from a threshold value, interpolating the one or more respiratory disturbance indices between adjacent time separated detection windows, and declaring a respiratory disturbance episode based on the detected respiratory disturbance state during the detection windows and the interpolation between detection windows.

Abstract: A tunneling tool for implanting a medical device into body tissue is described. The tunneling tool comprises a first leg and a second leg. An intermediate portion of the second leg is shaped to nest a medical device therein. A hub connects the first and second distal leg ends together. A sheath providing a lumen extends from the hub to an open end distal of the first and second legs. The first and second legs are manipulatable to separate the hub and the sheath into two portions, a first split portion connected to the first leg and a second split portion connected to the second leg. When a medical device is nested in the tunneling tool, breaking the tunneling tool apart enables the first and second split portions to be removed from body tissue, leaving the implanted medical device behind.

Abstract: In various examples, an apparatus is configured for subcutaneously inserting an implantable device within a patient. The apparatus includes a dilator portion including a dilator including a dilator length. The dilator portion is configured to separate tissue to create a subcutaneous pocket within the patient sized and shaped to accommodate an implantable device within the subcutaneous pocket. A sheath portion includes a sheath sized and shaped to accommodate the dilator within a sheath lumen. The sheath is configured to accommodate an antenna of the implantable device with the dilator removed from within the sheath. The sheath includes a sheath length that is at least substantially as long as an antenna length. The sheath is configured to separate to allow removal of the sheath around the implantable device to remove the sheath from and leave the implantable device within the subcutaneous pocket within the patient.

Abstract: A medical device includes a housing configured for implantation within a body of a patient. Detection circuitry is disposed in the housing and coupled to an electrode arrangement. The detection circuitry is configured to sense a cardiac electrical signal from the patient. A processor is coupled to the detection circuitry and configured to compute a first measure of heart rate variability (HRV) using the cardiac electrical signal, and compute a second measure of HRV using the cardiac electrical signal, the second measure of HRV differing from the first measure of HRV. The processor is also configured to produce an index of patient status derived from a ratio of the first and second measures of HRV, such that the index is a normalized HRV metric personalized to the patient. The processor or a remote system can use the index to assess acute and chronic changes in patient status.

Abstract: A medical device includes a housing configured for implantation within a body of a patient, and detection circuitry disposed in the housing and coupled to an electrode arrangement. The detection circuitry is configured to sense cardiac signals from the patient. A processor is coupled to the detection circuitry. The processor is configured to compare the cardiac signals to an initial detection threshold, automatically generate an additional detection threshold in response to a predetermined number of the cardiac signals meeting or exceeding the initial detection threshold or a previously generated detection threshold, count each occurrence of a cardiac signal meeting or exceeding each of the respective detection thresholds, and record cardiac signal data only for a cardiac signal that meets or exceeds the highest of the detection thresholds.
