    Abstract: The present disclosure relates to a system and method for coordinated laser delivery and imaging during an interventional procedure. A method may include activating an imaging source to provide a pulsed imaging signal and activating a laser source to provide a pulsed laser signal while the imaging source remains activated. The method may include coordinating the pulsed laser signal and the pulsed imaging signal to output each pulse of the pulsed laser signal and each pulse of the pulsed imaging signal in non-overlapping time windows. A system may include a controller in communication with the laser source and the imaging source for coordinating the output of the laser signal and the imaging signal.

    Abstract: 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.

    Abstract translation: 通过首先使围绕心脏壁的引线附着部位的区域稳定来实现引线尖端去除。 当充气时位于引线尖端处的气囊基本上垂直于引线膨胀，稳定了引线端周围的区域。 在进一步膨胀时，气囊基本上与铅平行地膨胀，导致引线尖端远离心壁。 在另一个实施例中，护套插入在引线上并前进到心脏壁。 被动或主动稳定装置连接到护套尖端以稳定引线尖端周围的区域。 在另一个实施例中，气囊位于护套的尖端，当充气时，气囊基本上垂直于导线膨胀，从而稳定了引线头周围的区域。 由于提供给引线尖端区域的稳定性，引线尖端以较小的力移除。
