    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.

    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.

    Abstract: A direct welding process for joining a current collector to a terminal pin in the construction of electrochemical cells is described. The resistance welding process utilizes increased current combined with an applied force to bond dissimilar metals with a melting temperature differential of preferably more than 500° C. Preferably, the method is used to bond the terminal pin to the cathode current collector. This method of attachment is suitable for either primary or secondary cells, particularly those powering implantable biomedical devices.

    Abstract: Methods and apparatus for implanting a neural stimulation lead in a patient's body are described. A lead assembly comprises a pointed-tip stylet, a stimulation lead, and an optional tube to deploy a fixation element attached to the lead. One embodiment of the implant methods starts with inserting the pointed-tip lead assembly directly into tissue. After the desired implant position is determined, the pointed-tip component is separated from the stimulation lead and removed from the tissue, leaving the stimulation lead implanted. After confirmation that the stimulation lead is in the right tissue location, the pointed-tip component is removed from the body, leaving the stimulation lead in place. The stimulation lead can be connected to a neurostimulator to delivery therapies to treat neural disorders, such as urinary control disorders, fecal control disorders, sexual dysfunction, and pelvic pain, etc.
