    摘要： A laser cutting system including a chamber configured to provide a controlled environment while the laser is being used to cut a pattern into a material to reduce or eliminate heat and oxygen related changes to the mechanical characteristics of the material. A system for providing a gas to the controlled environment within the chamber, as well as a means for exhausting gas and cutting debris from the chamber is also described. A cutting mandrel that provides for flow of a shielding gas and also provides a means for dispersing a laser beam before it can produce unwanted damage to a section of tubing is also described.

    摘要： A substantially anhydrous electropolishing electrolyte solution that includes at least one sulfate salt. The substantially anhydrous electropolishing electrolyte solutions described herein do not use water as a solvent; instead, such electropolishing electrolyte solutions use anhydrous alcohols and/or glycols as a solvent. For example, an electropolishing electrolyte solution, as described herein, may include an alcohol, at least one mineral acid, and at least one sulfate salt. The at least one sulfate salt can act as a source of sulfate ions to replenish sulfate ions consumed in the electropolishing process. Anhydrous sulfate salts can also act as water scavengers by reacting with water to form sulfate salt hydrates. Methods of electropolishing metal articles using such electropolishing electrolyte solutions are disclosed herein as well.

    摘要： Methods and apparatuses for the image guidance and documentation of medical procedures. One embodiment includes combining small field of view images into a recorded image of with a large field of view and aligning the small field of view real time image with the recorded image through correlation of imaging data. A location and orientation determination system may be used to track the imaging system and provide a starting set of image alignment parameters and/or provide change updates to a set of image alignment parameters, which is then further improved through correlating imaging data. The recorded image may be selected according to real time measurement of a cardiac parameter during an image guided cardiac procedure. Image manipulations planned based on the recorded image can be stored and applied to the real time information. The position of the medical device may be determined and recorded through manipulating a cursor in a 3-D image space shown in two non-parallel views.

    摘要： Catheter or guidewire mounted automatic vessel occlusion and fluid dispersion devices that expand to occlude or partially occlude a vessel when a fluid is flowing in the catheter or guidewire, and that automatically collapse when fluid flow is stopped. Each occlusion device has an elastic skeleton covered with a flexible cover coupled thereto and may have a hole(s) or openings in its distal or proximal end thereof to allow controlled flow through the desired end of the occlusion device. The fluid may be a flush fluid for enabling or improving the performance of imaging devices and image enhancing fluids, of treatment fluids for localized treatment of a vessel or tissues in communication with the vessel and/or of the transmission of energy to the vessel wall and adjacent tissues. Various embodiments are disclosed.

    摘要： An echogenic medical device, such as a needle catheter, which produces an improved ultrasonic image of the device, and a method of performing a medical procedure using a device of the invention. One aspect is directed to a catheter which reduces artifacts in the ultrasound image of the catheter. In one embodiment, the catheter has a spherical distal tip. Another aspect of the invention is directed to an echogenic catheter with echogenic portions arranged in an array to facilitate determination by ultrasonic imaging of the rotational orientation of the catheter relative to a desired location within the patient.
