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。

摘要： A wireless sensor for indicating a physical state within an environment includes a housing defining a hermetically sealed cavity. A structure located within the cavity of the housing has elements providing capacitance, the elements being arranged such that the distance and thereby the capacitance of the structure changes when a physical state of the environment changes. The structure has a resonant frequency based at least in part on the capacitance of the structure when in the presence of a fluctuating electromagnetic field. When the sensor is positioned within an environment and is subjected to a fluctuating electromagnetic field, the resonant frequency indicates the physical state of the environment.

A second conductive structureare formed on a surface of a second substrate, and the two substrates are mutually imposed such that the two conductive plates and coils are disposed in opposed, spaced-apart relation. A laser is then used to cut away perimeter portions of the imposed substrates and simultaneously to heat bond the two substrates together such that the cavity in the first substrate is hermetically sealed.

摘要： A stent constructed using elements containing micro-mechanical latching mechanisms is disclosed. The micro-mechanical latching elements allow sliding motion between two surfaces in one direction, and restrict sliding motion in the opposite direction. The micro-mechanical latch surface features are formed using microelectronic mechanical systems (MEMS) manufacturing methods. The male surface of the latching components contains an array of ridges or protrusions, and the receiving surface contains a matching array of recesses. The array of ridges or protrusions and the corresponding recesses have uniformly dissimilar slopes that result in a substantially greater frictional force in one direction than in the opposite direction. The separation distance between the two surfaces is such that the male latch surface is engaged with the receiving surface recesses in the low stress “locked” state, preventing motion in the undesired direction.
摘要翻译：公开了使用包含微机械闭锁机构的元件构造的支架。微机械闭锁元件允许在一个方向上的两个表面之间的滑动运动，并且在相反方向上限制滑动运动。使用微电子机械系统（MEMS）制造方法形成微机械闩锁表面特征。闩锁部件的阳表面包含脊或突起的阵列，并且接收表面包含匹配的凹槽阵列。脊或突起的阵列和相应的凹槽具有均匀不相似的斜面，其在一个方向上产生比在相反方向上显着更大的摩擦力。两个表面之间的分隔距离使得阳锁闩表面在低应力“锁定”状态下与接收表面凹部接合，从而防止在不期望的方向上的运动。
