Abstract: Intravascular imaging catheters are provided that include a distal sheath portion having a lumen that is configured to optionally receive a guidewire or an imaging assembly. The distal sheath portion may be configured to have dimensions such that when a guidewire is inserted through the lumen and extends through a distal exit port, the distal sheath portion may be employed as a microcatheter. External tissue may be imaged at a location at or near the distal end of the catheter, enabling, for example, the controlled imaging of a total occlusion, and the positioning of the distal end (and guidewire) within a true lumen associated with a total occlusion. A structural stop may be provided at or near the distal end of the distal sheath portion to prohibit extension of the imaging assembly out of the distal exit port, while permitting the extension of the guidewire through the distal exit port.

Abstract: Medical diagnostic devices and related methods of use are described in which one or multiple coils in a sensor, each coil connected with an RLC circuit and frequency counter, are held against a patient's head at predetermined cranial locations. Frequencies of the RLC circuit are measured and compared against those taken from known, control heads, to determine whether there is a medical problem and what type of problem. In some instances, too high of frequencies can reveal pooled blood in the head, a sign of hemorrhagic stroke, while too low of frequencies imply lack of blood supply, a sign of ischemic stroke. A head-mountable frame can assist a first responder in securing and guiding the coils and, along with fiducials, allow for automatic comparison of frequencies with the correct control data.
