Catheter for imaging and measurement of pressure and other physiologic parameters

A medical device, comprising:

• an elongated tube structure for insertion within a body, the tube structure comprising a proximal end, a distal end, and a lumen extending therethrough;
• one or more sensors of one or more sensor types coupled to a distal section of the tube structure;
• a guidewire positionable within at least a portion of the lumen of the tube structure and being translatable within the tube structure;
• and
• a first, proximal power and data coupling device configured to operably associate with a proximal section of the tube structure;
• and
• a second, distal power and data coupling device affixed to the distal section of the tube structure,
• wherein the proximal power and data coupling device and the distal power and data coupling device are configured to conductively contact the guidewire when the guidewire is inserted through the lumen of the tube structure to thereby enable passage of the electrical signals between the proximal power and data coupling device and the distal power and data coupling device via the guidewire,
• wherein the guidewire is translatable through the proximal power and data coupling device and the distal power and data coupling device.
