Abstract: A lithium ion electrochemical cell having an electrolyte with reduced carbonate content is described. The reduced carbonate electrolyte minimizes electrolyte out-gassing when the cell is exposed to temperatures above 100° C. The preferred electrolyte comprises a primary solvent of γ-butyrolactone and a secondary solvent comprising an aliphatic or halogen constituent. A most preferred electrolyte consists essentially of γ-butyrolactone as a primary solvent, fluorotoluene as a secondary solvent, and an electrolyte additive formulation of vinylene carbonate, fluorinated ethylene carbonate, and polyvinyl pyridine-co-styrene. An alkali metal salt is added to the solvent admixture.

Abstract: A secondary header for an active implantable medical device (AIMD) incorporates a secondary header plug configured for mating insertion into an AIMD ISO DF4 or IS4 connector cavity, a secondary header ISO DF4 or IS4 connector cavity, and at least one replacement lead connector cavity. The secondary header plug has four electrical contacts which correspond to four electrical contacts of the AIMD connector cavity. The secondary header connector cavity has less than four electrical contacts conductively coupled to the secondary header plug electrical contacts. The replacement lead connector cavity has at least one electrical contact conductively coupled to at least one electrical contact of the secondary header plug. An intermediate conformal section between the secondary header plug and a housing for the secondary header connector cavity places the secondary header connector cavity housing adjacent to an exterior surface of the AIMD.

Abstract: A method of identifying a location for applying a stimulation therapy to treat a patient includes stimulating a first body region of the patient transcutaneously via a stimulus generator. The body region contains a first portion of a nerve that has an elongate shape. In response to the stimulating, action potentials received from a second portion of the nerve are monitored over a period of time. The second portion of the nerve is in a second body region of the patient that is located remotely from the first body region. Based on the monitoring, an optimized location of the second portion of the nerve is determined for applying the stimulation therapy to treat the first body region.

Abstract: A medical device for providing an electrical stimulation therapy for a patient includes a microcontroller configured to generate a plurality of electrical pulses and a control signal. The medical device includes a stimulation driver coupled to the microcontroller. The stimulation driver is configured to amplify the electrical pulses into amplified electrical pulses to be delivered to the patient as a part of the electrical stimulation therapy. The medical device includes a battery configured to supply a first voltage. The medical device includes a voltage up-converter coupled between the battery and the stimulation driver.

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: Tantalum powders produced using a tantalum fiber precursor are described. The tantalum fiber precursor is chopped or cut into short lengths having a uniform fiber thickness and favorable aspect ratio. The chopped fibers are formed into a primary powder having a controlled size and shape, narrow/tight particle size distribution, and low impurity level. The primary powder is then agglomerated into an agglomerated powder displaying suitable flowability and pressability such that pellets with good structural integrity and uniform pellet porosity are manufacturable. The pellet is sintered and anodized to a desired formation voltage. The thusly created capacitor anode has a dual morphology or dual porosity provided by a primary porosity of the individual tantalum fibers making up the primary powder and a larger secondary porosity formed between the primary powders agglomerated into the agglomerated powder.

Abstract: An improved splittable medical device introducer designed to introduce a medical device such as a lead or catheter, into a patient's vasculature without loss of blood or introduction of air is described. The introducer assembly is designed with a notch provided at the proximal end of the introducer housing. The notch, which may comprise a multitude of cross-sectional geometries, is designed to reduce the force required to separate the housing and the introducer sheath, thereby minimizing the possibility of unintentional dislodgement during separation. The notch also increases the repeatability and consistency of the amount of force required to separate the introducer housing and sheath.
