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: A torque limiting tool is described. The tool comprises a two stage torque limiting mechanism that resides within a housing. The torque limiting mechanism comprises a shank positioned through a gear, a plate, and a bias member. The plate is constructed having at least one post and at least one tooth providing a ramp surface that extends outwardly from a plate surface. The gear is constructed having at least one recess providing at least one inclined surface that resides part-way within the thickness of the gear. The gear and plate are positioned in opposition so that the at least one tooth and extending post are received within or detachably mated to the opposing recess and through-bore. Torque is transferred therebetween the plate and gear when the ramped teeth and extending posts mate with the respective recess and through-bore. A first torque limit is exceeded when the post breaks free from the through-bore. A second, lesser torque limit is exceeded when the ramped teeth release from their mated recess.

Abstract: A multilayer helical wave filter having a primary resonance at a selected RF diagnostic or therapeutic frequency or frequency range, includes an elongated conductor forming at least a portion of an implantable medical lead. The elongated conductor includes a first helically wound segment having at least one planar surface, a first end and a second end, which forms a first inductive component, and a second helically wound segment having at least one planar surface, a first end and a second end, which forms a second inductive element. The first and second helically wound segments are wound in the same longitudinal direction and share a common longitudinal axis. Planar surfaces of the helically wound segments face one another, and a dielectric material is disposed between the facing planar surfaces of the helically wound segments and between adjacent coils of the helically wound segments, thereby forming a capacitance.

Abstract: A method of programming electrodes includes automatic current balancing and lock control. A virtual representation of a lead is displayed. The lead includes a plurality of electrodes. A subset of the electrodes is selected for programming. Each of the electrodes in the subset has one of two polarities. The two polarities are anode and cathode. A first percentage of a total stimulation current is assigned to a first one of the electrodes in the subset. In response to a user input, the first percentage is fixed to the first electrode. A plurality of second electrodes in the subset that have the same polarity as the first electrode is identified. Thereafter, a respective second percentage of the total stimulation current is automatically assigned to each of the second electrodes. A sum of the first percentage and the respective second percentages is equal to 100%.

Abstract: A hermetically sealed feedthrough filter assembly is attachable to an active implantable medical device and includes an insulator substrate assembly and a feedthrough filter capacitor disposed on a device side. A conductive leadwire has a proximal leadwire end extending to a distal leadwire end, wherein the proximal leadwire end is connectable to electronics internal to the AIMD. The distal leadwire end is disposed at least partially through a first passageway of the feedthrough filter capacitor and is in contact with, adjacent to or near a device side conductive fill. A first electrically conductive material makes a three-way electrically connection that electrically connects the device side conductive fill to an internal metallization of the feedthrough filter capacitor and to the distal leadwire end. A second electrically conductive material electrically connects an external metallization of the feedthrough filter capacitor to a ferrule or an AIMD housing.

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.
