First Claim
Patent Images
1. A catheter for in vivo imaging comprising:
- a catheter sheath body defining a central lumen and a distal tip, the central lumen terminating at the distal tip and the distal tip having a guidewire lumen formed therein, the guidewire lumen being separate from the central lumen and having a guidewire entrance port and a guidewire exit port, the guidewire entrance port and the guidewire exit port each being positioned distal to the termination of the central lumen; and
an optical train positioned within the central lumen, the optical train comprising a rotary drive shaft configured to rotate a distal end imaging assembly about a longitudinal axis, the rotary drive shaft comprising a proximal hypotube shaft having a distal end overlapping a proximal end of a distal single-layer stranded hollow core shaft, wherein the stranded hollow core shaft comprises helically wound metal wires fixedly engaged with neighboring metal wires on their respective outer surfaces.
