摘要： Various fixation techniques for implantable medical device (IMDs) are described. In one example, an assembly comprises an IMD; and a set of active fixation tines attached to the IMD. The active fixation tines in the set are deployable from a spring-loaded position in which distal ends of the active fixation tines point away from the IMD to a hooked position in which the active fixation tines bend back towards the IMD. The active fixation tines are configured to secure the IMD to a patient tissue when deployed while the distal ends of the active fixation tines are positioned adjacent to the patient tissue.

摘要： A physiologic sensor device configured to be placed on an appendage. The sensor device includes a foldable portion designed to be deformed around the tip of the appendage. In some embodiments the foldable portion is a soft compressible material. In other embodiments a stabilization component is provided to isolate sensing elements from external forces. Some embodiments also include a deformable frame that folds in response to a bending force as the sensing device is placed on the appendage. The deformable frame holds the sensor device in place until another bending force is applied. In other embodiments the frame and/or sensor elements are removable and disposable relative to other components of the sensor device.

摘要： An atherectomy device is disclosed, with a clutch between the motor and the drive shaft. The clutch includes two plates that rely on frictional to transmit torque from one plate to the other. The clutch has an attractive magnetic normal force that holds the plates together. For relatively low torques, as is the case during normal use, a static frictional torque holds the plates together, and the plates spin together without slipping. For relatively high torques, as occurs when the distal end of the drive shaft encounters an obstacle and stops abruptly, the high torque exceeds the maximum possible static frictional torque, and the plates slip. When slipping, the plates transmit a kinetic frictional torque that is low enough to avoid damage to the patient or to the atherectomy device. In some cases, the torque levels associated with a stoppage of the drive shaft distal end are chosen to mimic those of a known atherectomy device, in which a gas-driven turbine is clutchlessly attached to the drive shaft.
摘要翻译：公开了一种粥样斑块切除装置，其中电动机和驱动轴之间具有离合器。离合器包括两个依靠摩擦传递扭矩从一个板到另一个板的板。离合器具有吸引力的法向力，将板保持在一起。对于相对较低的扭矩，如正常使用情况下，静摩擦转矩将板保持在一起，并且板旋转在一起而不滑动。对于相对较高的扭矩，当驱动轴的远端遇到障碍物而突然停止时，高扭矩超过最大可能的静摩擦转矩，并且板滑动。当滑动时，板传递足够低的动力学摩擦转矩，以避免对患者或粥样斑块切除装置造成伤害。在一些情况下，与驱动轴远端的停止相关联的扭矩水平被选择为模拟已知的粥样斑块切除装置的扭矩水平，其中气体驱动涡轮机无离子地附接到驱动轴。

摘要： A medical device configured to be temporarily secured at a tissue field, such as a fetal skull, via a spiral probe. The spiral probe functions to both secure the sensor in place and provide an electrode for ECG purposes. The spiral probe is non-uniform and includes one or more of a stop element, a cross bar element and a collapsed portion adapted to engage tissue after a predetermined rotation of the probe into the tissue field. The probe diameter can expand with an increase in torque applied to a drive rod, leading to disengagement of the drive rod from the probe. The spiral probe and drive rod may define a detent mechanism whereby upon reaching a predetermined torque the drive rod is disengaged from the probe and freely rotates without further entry of the spiral probe into the tissue field.
摘要翻译：一种被配置为经由螺旋探针临时固定在诸如胎儿头骨的组织场的医疗装置。螺旋探头用于将传感器固定到位，并提供用于ECG目的的电极。螺旋探针是不均匀的，并且包括止动元件，横杆元件和折叠部分中的一个或多个，其适于在将探针预定旋转到组织区域中之后接合组织。探头直径可以随施加在驱动杆上的扭矩的增加而膨胀，导致驱动杆与探头分离。螺旋探针和驱动杆可以限定制动机构，由此当达到预定扭矩时，驱动杆从探头脱离并自由旋转，而不再进一步将螺旋探针进入组织区域。
