    摘要： A medical electrical lead comprises a flexible, elongate lead body extending along a longitudinal axis and having a proximal end and a distal end. A protective distal tip structure is disposed on the distal end of the lead body. The tip structure includes a plurality of compliant projections each extending distally from the distal end of the body in the direction of the longitudinal axis. The projections are configured to contact and bear against cardiac tissue when the lead is implanted, and are deformable under the action of an axially or radially directed force. The projections optionally include a coating over a substrate. The coating can include a hydrogel material and/or a pharmaceutical agent such as a steroid for reducing inflammation at the implantation site.

    摘要： Methods of implanting a two-part cardiac lead in a heart are disclosed. The two-part cardiac lead has inner and outer portions and a pin. The inner and outer lead portions are separately advanced to a location of interest within the vasculature of a patient. The pin is attached to a proximal end of the inner lead portion and can provide a connection between the inner and outer lead portions.

    摘要： The present invention relates to a porous surface electrode including a capacitive layer and a method of making the same. The porous surface electrode of the present invention includes a more thin capacitive coating that preserves the underlying structure of the porous surface. By controlling one or more processing parameters the average thickness and surface morphology of the capacitive coating can be controlled.

    摘要： An implantable medical device lead includes an insulative lead body, an outer conductive coil extending through the lead body, and an inner conductive coil extending coaxially with the outer conductive coil. The outer conductive coil is coupled to a proximal electrode at a distal end of the outer conductive coil, and the inner conductive coil is coupled to a distal electrode at a distal end of the inner conductive coil. A cooling assembly is thermally coupled to the distal electrode to dissipate heat generated at the distal electrode during exposure to magnetic resonance imaging (MRI) fields.
