    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 of the type employing an elongated introducer sleeve for receiving a catheter or lead body and an associated hemostasis clamp including a clamping member configured to engage the outer circumference of the introducer sleeve. The clamp is provided with a mechanism for maintaining the clamping member in engagement with said outer circumference of the sleeve to compress the outer circumference of the sleeve around a catheter or lead body inserted therethrough. In some embodiments the clamp takes the form of a hinged clamp provided with two jaws each having a recess adapted to engage a portion of the other circumference of the introducer sleeve. In other embodiments the clamp takes the form of interacting ramped members. The clamp is maintained in engagement with the sleeve either resiliently or by means of a latch.
