摘要： The invention provides a rotational atherectomy system, device and method comprising a flexible, elongated, rotatable drive shaft with an abrasive section within a pre-curved section of the drive shaft. The device may further comprise a concentric or eccentric enlarged diameter section that is at least partially covered with abrasive material to comprise the abrasive section. The abrasive section may further comprise an abrasive crown or burr mounted to the drive shaft. The pre-curved drive shaft allows smaller diameter and/or massive abrasive regions to be used while sweeping larger diameters during high-speed rotation. The pre-curved region is substantially straightened for insertion into vasculature and placement adjacent stenosis by insertion of the guide wire. Removal of guide wire proximally from the pre-curved region allows the drive shaft to return to its pre-curved form for ablation. Reinsertion of the guide wire beyond the pre-curved region straightens the drive shaft for ease of removal.
摘要翻译：本发明提供一种旋转粥样斑块切除系统，装置和方法，其包括柔性的，细长的，可旋转的驱动轴，在驱动轴的预弯曲部分内具有研磨部分。该装置可以进一步包括同心或偏心的扩大直径部分，其至少部分地被研磨材料覆盖以包括研磨部分。研磨部分还可以包括安装到驱动轴上的研磨表冠或毛刺。预弯曲的驱动轴允许在高速旋转期间使用更小的直径和/或大的磨料区域，同时扫掠更大的直径。预弯曲区域基本上被拉直，用于插入脉管系统并通过插入导丝而邻近狭窄放置。从预弯曲区域向近侧移除导丝线允许驱动轴返回其预弯曲形式以进行消融。引导线超过预弯曲区域的再插入使驱动轴伸直以便于移除。

摘要： An atherectomy device is disclosed, which is rotationally driven by an electric motor. In some designs, the device includes features unavailable on gas turbine-driven systems, such as the storing in memory of low/medium/high preset rotation speeds for particular models of handle, calculations of the amount of saline left in the IV and associated warnings when it gets sufficiently low, and automatic adjustment of the IV pump rate to a predetermined or calculated level when the rotational speed of the motor is changed. The electric motor has far more rotational inertia than a comparable gas turbine, so the system includes a control mechanism that helps prevent damage from excessive torque being applied to the distal end of the drive shaft. When an obstruction at the distal end is detected, by a drop in the motor rotational speed, the motor is released and is allowed to spin freely as a flywheel. The freely-spinning motor allows the large angular momentum of the system to dissipate rapidly and safely, without excessive torque to the drive shaft.

摘要： A data processing apparatus is provided for producing a randomized value. A cell in the data processing apparatus comprises a dielectric oxide layer and stress voltage circuitry is configured to apply a stress voltage across the dielectric oxide layer of the cell to cause an oxide breakdown process to occur. Oxide breakdown detection circuitry is configured to determine a current extent of the oxide breakdown process by measuring a response of the dielectric oxide layer to the stress voltage and randomized value determination circuitry is configured to determine a randomized value in dependence on the current extent of the oxide breakdown process.

摘要： A balloon catheter is provided having an expandable distal portion and balloon protector means comprising a first removable sleeve having a variable inner diameter to ease sliding the first sleeve over the balloon, and an optional second removable (outer) sleeve positioned over the inner sleeve, the second (outer) sleeve having a constrictive relationship with the first (inner) sleeve, said first and second sleeves being removed prior to use of the catheter. A stent delivery system is provided to facilitate introduction and placement of a stent, and includes a catheter having an expandable distal portion constructed and arranged for expanding the outer diameter of the catheter from a contracted state to an expanded state, said distal portion further comprising a balloon and at least one dam over which the balloon extends, and a stent positioned around the distal portion of the catheter around the balloon or gripper linear control device, said stent having a contracted condition, being sized in the contracted condition to closely surround the balloon in the contracted state, and being expandable to an expanded condition; a first removable (inner) sleeve in the region of the distal portion of the catheter positioned around the stent (and between the dams where the device comprises two dams), said first sleeve comprising a first end, a second end and a variable inner diameter to ease sliding the sleeve over the balloon and stent; an optional second removable (outer) sleeve positioned over the stent, first sleeve and at least one dam, said second (outer) sleeve having a constrictive relationship with the first (inner) sleeve, whereby when compressed by the outer sleeve, the inner sleeve will have an inner diameter approximately equal to or less than the outer profile of the collapsed balloon over the at least one dam, said first and second sleeves being removed prior to use of the stent delivery system and release of the stent by expansion of the balloon.

摘要： Methods and devices for providing temporary placement of a filter in a blood vessel are disclosed. A filter delivery system in accordance with one exemplary embodiment of the present invention includes a catheter having an elongate shaft and a tubular member disposed within a shaft lumen defined by the elongate shaft. The elongate shaft also includes a proximal end, a distal end, and a wall defining the shaft lumen. The tubular member has a first end fixed to the wall of the elongate shaft, and a second end disposed within the shaft lumen. The tubular member defines a guidewire lumen that is in fluid communication with a distal guidewire port defined by the second end of the tubular member. The catheter also includes a proximal guidewire port extending through the wall of the elongate shaft. A filter may be disposed within a distal portion of the shaft lumen. A distal end of a guidewire is fixed to the filter. The guidewire preferably extends through the distal guidewire port, the guidewire lumen, and the proximal guidewire port.
