Abstract: An exemplary catheter includes a housing having the distal catheter region configured to be at least partially disposed in a body and the proximal catheter region configured to remain at least partially outside of the body. The catheter may define an imaging lumen configured to receive an imaging device, a guidewire lumen, an off-ramp, and an indicator lumen configured to receive an indicator that is detectable by the imaging device. The guidewire lumen is configured to receive a guidewire and includes a distal region and a proximal region. The off-ramp extends from the guidewire lumen at or near an intersection of the distal and proximal regions of the guidewire lumen. The catheter may also include one or more guidewire feeders configured to cause the guidewire to move from the proximal section to the off-ramp.

Abstract: An engine mounted fuel manifold configured to inhibit gelling of fuel is provided, comprising: a housing comprising an internal chamber configured to receive drain fuel from a pump, an accumulator and a fuel injector, and a recirculation passage in fluid communication with the internal chamber to receive the drain fuel; a tank fuel port configured to receive fuel from a fuel tank; an output port configured to output fuel to a filter; a fuel supply passage in communication with the tank fuel port and the output port; and a thermal recirculation valve in fluid communication with the recirculation passage and the fuel supply passage, the valve responding to temperatures of fuel received by the tank fuel port being below a predetermined value by mixing drain fuel from the recirculation passage with fuel in the fuel supply passage, thereby causing mixed fuel to be supplied to the filter.
