A method and apparatus for the treatment of intravascular blockages includes introducing a medicament and ultrasound to the blockage, monitoring the blockage or bleeding to determine a status thereof and controlling the agent introduced to the blockage based upon the monitoring.

Processing data in a computer-aided design (CAD) system includes determining that a feature of a three-dimensional model has a condition that requires correction. The condition is automatically corrected by performing an action. The action may be an action that reorders a sequence of features in the three-dimensional model, an action that changes at least one parameter of the feature, an action that deletes a feature reference, or an action that changes a feature reference. Furthermore, the action may have one or more constraints that bound the action to a set of features that are directly and indirectly related to the feature on which the action operates.
摘要:
A multi-purpose clamping device that stabilizes and holds a wide variety of irregularly shaped objects by means of a stationary and a movable jaw, a linear ratchet and a rotary power cam; both used to engage the work piece, a pair of conformable jaw faces consisting of an array of spring-loaded pins to grasp the work piece, and a base with retractable stabilizing outriggers that ground and stabilize the work. The device is configured in such a way that it will lay flush on one side so that it can be used as a vise in an alternate orientation to allow access from both the top and the side. The base is also configured to allow the clamp portion to detach from the base in order to be used separately as a clamp.

摘要:
An improved single- or multiple-dose syringe having a conventional housing and an improved plunger configuration carrying a medicament- or saline-filled cartridge the contents of which are sequentially dispensed after the dispensing of a volume of a drawn-up primary fluid. A method for sequential administration of medicinal fluids using the improved syringe is also a part of the invention.

A communication adapter connected between a communication line and a host processor segments a received data frame by storing the received data in a buffer chain made up of equal length buffers. As each buffer is filled, the adapter interrupts the host. The host moves the data stored in the filled buffer into its own storage. It interrupts the adapter so that the buffer can be returned to the chain of free buffer and completes transmission protocol processing before the entire frame is received. If the frame has been received without error or buffer overrun it is delivered to the user immediately after transfer of the last buffer.
摘要:
An ultrasonic angioplasty device comprising an elongate ultrasound transmission member having a proximal end attachable to an ultrasound generating device and a bulbous distal head or probe formed on the distal end thereof for effecting ablative treatment of an occluding lesion. The ultrasound transmission member may be formed of one or more superelastic metal alloys such as NiTi (50 at. % Ni). A guidewire lumen may be formed in the distal head or probe to permit passage of a guidewire therethrough. Portions of the ultrasound transmission member may be curved or bent. Portions of the ultrasound transmission member may be tapered or narrowed. One or more surface disruptions may be formed on the distal head or probe to improve treatment efficacy. An increased hardness coating or outer skin may be formed on the ultrasound transmission member. The device of the present invention may be incorporated into an angioscopic device.

摘要:
A micromechanical component and a method of producing same are described; the component has a supporting body, in particular a silicon body, and a membrane which is connected to the supporting body and is unsupported at least in some areas. The membrane is also provided with at least one stabilizing element in an unsupported area in some areas of the surface. The method described here includes the following process steps: a) forming a first area within the supporting body including at least a first surface area of the supporting body; b) forming a second surface area of the supporting body which is in the first surface area in at least some areas; c) selective etching of the first area down to an adjustable depth, forming porous silicon, the second surface area being at least almost not etched; d) depositing a membrane layer on the surface of the supporting body, with the membrane layer covering the first area that has been rendered porous in at least some areas and covering the second surface area in at least some areas, and e) selectively removing the first area which has been rendered porous.
