摘要:
Lead tip removal is accomplished by first stabilizing an area around the lead tip attachment site in the heart wall. A balloon located at the tip of the lead when inflated expands substantially perpendicular to the lead, stabilizing the area around the lead tip. Upon further inflation, the balloon expands substantially parallel with the lead, causing the lead tip to pull away from the heart wall. In another embodiment, a sheath is inserted over the lead and advanced to the heart wall. A passive or active stabilization device is attached to the sheath tip to stabilize the area around the lead tip. In another embodiment, a balloon is located at the tip of the sheath that, when inflated, expands substantially perpendicular to the lead, stabilizing the area around the lead tip. The lead tip is removed with less force due to the stabilization provided to the lead tip area.
