    摘要: Electrical medical leads having active fixation electrodes, particularly helix electrodes intended to be screwed into body tissue, e.g., the heart, are disclosed having selectively applied insulation to optimize exposed electrode surface area and dispose the exposed electrode surface area toward tissue that is less traumatized by injury caused by screwing in the fixation helix. In a preferred fabrication method, an outer helical surface is masked by contact with a masking tube while a dielectric coating is applied to the inner helical surface of the coil turns of the helix, and the masking tube is removed when the dielectric coating has set. In one variation, at least one aperture is formed through the masking tube sidewall exposing an area of the outer helical surface thereby interrupting the uninsulated outer helical electrode.

    摘要: A medical fluid delivery system includes an implantable medical lead including a fixation element adapted to secure the lead to a tissue site and a fluid delivery device including a tissue piercing distal tip; the device is adapted to pass through a proximal port, a lumen and a distal port of the lead. The system further includes means for adjusting a position of the device distal tip with respect to the lead distal port.

    摘要: An implantable lead system includes an elongated device slideably engaged within a lumen of a lead body. A distal portion of the elongated device is slidable through a helix tip coupled to a distal end of the lead body by passing through a pierceable fluid-tight seal disposed in proximity to the distal end of the lead body; the seal prevents ingress of bodily fluid into the lumen of the lead body.
