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： A controlled volume inflation-deflation device to inflate a balloon to occlude a blood vessel by dialing a knob that locks at rotational positions to locate a plunger at equally spaced locations within a syringe of the inflation-deflation device. The inflation-deflation device includes a releasable latch to lock the proximal and distal housings together to hold the plunger forward for occlusion, and to separate and hold the proximal and distal housings to retract the plunger for perfusion. When the inflation-deflation device is returned to the-latched position, the balloon is re-inflated to its previous occlusive diameter. Also, an extension tube made of a lower modulus outer material co-extruded over and miscible with a higher modulus inner material may be used to produce a suitably low compliance extension tube for the inflation-deflation device. The balloon may have tapered ends and a cylindrical center portion so that it increases by more equal increments in outer diameter in response to incremental equal increases in inflation volume.

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, including embodiments having provisions for the rapid expansion and collapse of the occlusion device or alternately, for the rapid expansion of the device, followed by much slower collapse of the device.

摘要： An infusion catheter having a distal shaft with an infusion tube extending from a proximal end to a distal end of the distal shaft, and a proximal cannula with an inner dimension and a distal end attached to a proximal end of the distal shaft to define an opening between the inner diameter of the infusion tube and the inner dimension of the proximal cannula. Also, a guidewire tube disposed within the inner dimension and the distal shaft and extending from the proximal end of the proximal cannula to the distal end of the distal shaft. The inner diameter of the infusion tube, the opening, the exterior dimension of the guidewire tube and the inner dimension cooperate and define sufficient cross sectional sizes to allow a treatment agent to be infused between the proximal end of the proximal cannula and the region of interest.

摘要： Methods and apparatuses for positioning medical devices onto (or close to) a desired portion of the interior wall of an internal channel, such as for scan imaging, for photodynamic therapy and/or for optical temperature measurement. In one embodiment, a catheter assembly has a distal portion that can be changed from a configuration suitable for traversing the internal channel to another configuration suitable for scan at least a spiral section of the interior wall of an internal channel, such as an artery. In one example, the distal portion spirals into gentle contact with (or close to) a spiral section of the artery wall for Optical Coherence Tomography (OCT) scanning. The spiral radius may be changed through the use of a guidewire, a tendon, a spiral balloon, a tube, or other ways.
