Abstract: An implantable medical lead may include an electrode at a distal portion of the lead that is configured to monitor or provide therapy to a target site. The lead may include a visible indicator that is visible to the naked eye of a clinician at a medial portion of the lead that is configured to indicate when the electrodes of the lead are longitudinally and radially aligned properly to monitor or treat the target site. A clinician may insert the lead into the patient using an introducer sheath inserted to a predetermined depth into the patient and subsequently aligning the distal portion of the lead by orienting the indicator at an entry port of the introducer sheath.

Abstract: A relatively compact implantable medical device includes a fixation member formed by a plurality of fingers mounted around a perimeter of a distal end of a housing of the device; each finger is elastically deformable from a relaxed condition to an extended condition, to accommodate delivery of the device to a target implant site, and from the relaxed condition to a compressed condition, to accommodate wedging of the fingers between opposing tissue surfaces at the target implant site, wherein the compressed fingers hold a cardiac pacing electrode of the device in intimate tissue contact for the delivery of pacing stimulation to the site. Each fixation finger is preferably configured to prevent penetration thereof within the tissue when the fingers are compressed and wedged between the opposing tissue surfaces. The pacing electrode may be mounted on a pacing extension, which extends distally from the distal end of the device housing.

Abstract: A medical electrical lead may include a conductive electrode shaft located near the distal end within the lead body, a coiled conductor extending within the lead body from the proximal end and coupled to a first end of the conductive electrode shaft, and an electrode located near the distal end of the lead body and coupled to an opposite end of the conductive electrode shaft as the coiled conductor. The lead may also include an energy dissipating structure located near the distal end of the lead body and defining a lumen through which a portion of the coiled conductor extends. The energy dissipating structure may include a region having one or more protrusions extending toward a central axis of the lumen to push the coiled conductor off center relative to the central axis of the lumen.

Abstract translation: 医疗电引线可以包括位于引线主体内的远端附近的导电电极轴，从该近端延伸到引线主体内并连接到导电电极轴的第一端的线圈导体，以及位于导体主体附近的电极 引线主体的远端并且与导线电极轴的相对端耦合，作为线圈导体。 引线还可以包括位于引线主体的远端附近的能量消散结构，并限定一个内腔，一部分螺旋导体穿过该内腔延伸。 能量耗散结构可以包括具有一个或多个突出部的区域，该突出部朝着内腔的中心轴线延伸，以将线圈导体相对于管腔的中心轴线中心推出。
