    摘要: A medical system for electrical stimulation includes a first column of electrodes, a second column of electrodes, an expandable member disposed between first and second columns, and an expansion mechanism adapted to transmit an externally applied pressure to the expandable member. The pressure expands the expandable member in order to force the first column of electrodes apart from the second column of electrodes. The first and second columns, disposed side-by-side, may be inserted through a percutaneous needle and into a epidural space, alongside a spinal cord; after insertion, the first column may be forced apart from the second column by applying the pressure to the expandable member.

    摘要: An intrathecal catheter for delivering fluid to, or withdrawing fluid from, the cerebrospinal fluid compartment of a patient, includes a proximal end and a distal portion. The distal portion has an outer diameter of about 1 mm or less, a bending stiffness of about 0.002 pounds per square inch or less, and a distal end. A delivery region is located between the proximal end and the distal end, and a lumen extends from the proximal end to the delivery region. The catheter may further include a coiled structure region to prevent dislodgement of the catheter from a tissue in which the coiled structure is implanted, for example the cisterna magna. The catheter may also include tines to anchor portions of the catheter, for example to a portion of the spinal canal.

    摘要: A lead and a lead system for dispersion of a cardioversion/defibrillation electrode formed of one or more small diameter defibrillation electrodes in a heart chamber and for attaching a pace/sense electrode in contact with the heart. The small diameter defibrillation electrode or electrodes extend distally from the distal end of the lead body. If multiple electrodes are employed, they are preferably biased to spread apart when unrestrained and have a cross-section size small enough to be inserted into interstices of trabeculae in the ventricular chamber. The distal ends of the defibrillation electrodes may be free of attachment to the lead body or may be attached by a weak bond to the distal portion of the lead.

    摘要: An introducer system featuring a sheath which is kink resistant. Such a sheath thereby permits the sheath to be dramatically bent while still allowing a lead to be introduced therethrough. The kink resistance is provided by a composite construction of the sheath. In particular the sheath has at least one integral reinforcing fiber. In the preferred embodiment the reinforcing fibers are provided in a braided configuration. The sheath preferably is constructed to be readily split using a slitter in a longitudinal direction and thus permits the sheath to be removed from the venous system without having to withdrawn the sheath over an end of the pacemaker lead. In an alternate embodiment the sheath is scored, including the reinforcing fibers, to thereby permit the sheath to be longitudinally split apart and removed from the venous system without having to withdrawn the sheath over an end of the pacemaker lead.

    摘要: A cardiac transvenous defibrillation lead has a continuous coil conductor within a layer of insulation. A portion of the coil conductor is exposed as a defibrillation electrode. In order to enhance fluoroscopic visualization of the exposed electrode during implant, the end of the exposed electrode is marked with a radiopaque element. The element may be in the form of an adhesive filled with radiopaque material that is used to backfill under the layer of insulation. Alternatively, a tube made of radiopaque material may be installed between the layer of insulation and the coil conductor.
