摘要： An apparatus for interventional treatment of atherosclerosis at a vascular bifurcation includes structure for receiving a first guidewire and a second guidewire. An exit for the second guidewire is located in a central section of the structure. A first balloon portion is secured to the structure so a proximal end is located adjacent the exit. A second balloon portion is secured to the structure so a distal end is located adjacent the exit on a side of the exit opposite the first balloon portion. An annular gap is defined between the proximal end of the first balloon portion and the distal end of the second balloon portion. The annular gap, at a radial outermost location relative to the structure, has a width that is equal to or less than a width of the annular gap at a radially innermost location relative to the structure. The apparatus also includes an expandable stent that is mountable about the first and second balloon portions.

摘要： A ventricular assist device comprises a sheet of hydraulically actuated material that can be affixed to prescribed locations on the surface of the heart to assist areas of the heart that do not contract normally. The material is comprised of a network of contractible unit cells that individually contract when fluid is pumped into them. These unit cells are connected together in a network that causes the sheet to contract radially inward. This contraction causes the sheet to transmit forces to the heart to assist in its natural contraction. A sensing function coordinates the contraction of the sheet with the contraction of the heart. The change in shape of the device is accomplished by distributing pressurized fluid throughout the spaces of the device by way of a network of channels. When pressure is removed from the fluid system, it assumes a deenergized “rest” position in which it does not transmit any forces to the surface of the heart. This property of the device prevents the device from inhibiting the heart's natural contractions in the event of a failure of the device or a loss of hydraulic power.
摘要翻译：心室辅助装置包括一片液压致动材料片，该片材可以固定在心脏表面上的规定位置，以帮助心脏不能正常收缩的区域。该材料由可收缩的单体电池网络组成，当将流体泵入其中时单独收缩。这些单电池在网络中连接在一起，导致片材向内径向收缩。这种收缩导致片材将力传递到心脏以帮助其自然收缩。检测功能可以协调纸张与心脏收缩的收缩。设备形状的变化通过通过通道网络将加压流体分配到设备的整个空间中来实现。当压力从流体系统移除时，它承受断电的“静止”位置，在该位置，它不会将任何力传递到心脏表面。该装置的这种特性防止装置在装置发生故障或液压动力损失的情况下抑制心脏的自然收缩。
