SINGLE PASS A-V LEAD |
摘要 |
<p>A dual chamber pacing lead requiring but a single transvenous pass for implantation. The ventricular electrode has tines for sustaining acute and chronic fixation. The ventricular electrode is coupled to a first conductor which is space wound having an insulation sheath. The proximal end of the first space wound coil protrudes slideably from a first connector pin of a bifurcated connector assembly. An optional stylet may be inserted into the first space wound coil to assist in ventricular placement. A second space wound coil is slideably located over the first space wound coil. The second space wound coil serves as a support means rather than a conductor. The proximal end of the sec-ond space wound coil is fixedly attached to the connector assembly. The first space wound coil protrudes near the distal end of the second space wound coil. A third space wound coil having an insulating sheath serves as a conductor having the distal end attached to the tined atrial electrode and the proximal end coupled to a second pin of the bifurcated cable. The distal end of the third space wound coil is located coaxially within the second space wound coil. A stylet straightens the distal end of the third space wound coil which assumes a "J" shape upon removal of the stylet. An outer sheath encloses the second and third space wound coils from the bifurcated connector to the atrial electrode.</p> |
