    摘要： Guidewire exit ramp members that may be placed over a tubular member having a guidewire lumen, which longitudinally extending and laterally accessible, and methods of use. The guidewire exit ramp member can be placed to force a guidewire loaded through the lumen in a first direction to be forced out of the lumen via an opening, slit or channel. The guidewire exit ramp member, in an illustrative embodiment, takes the form of a relatively short member having a proximal portion and a distally extending flap. The flap may be designed to enter and remain in a longitudinally accessible guidewire lumen. Combinations of such ramp members and device shafts having longitudinally extending laterally accessible guidewire lumens are also disclosed, as are methods for securing such combinations together. A method of backloading a guidewire into a catheter while causing lateral exit of the guidewire at a desired location is also shown.

    摘要： A steerable imaging catheter is provided, including an elongated catheter tube, at least one steering cable extending along the catheter tube to control the movement of the distal end thereof, and a fiber optic cable extending along the catheter tube. The fiber optic cable transmits illumination light from its proximal end to its distal end and transmits an image from its distal end to its proximal end. In one embodiment, two or more steering cables are used, and the catheter tube is configured to have greater flexibility near its distal end than its proximal end so as to concentrate the movement (flexing) of the catheter tube at its distal end. The use of two or more steering cables, together with the catheter tube having varying flexibility, permit better control of the distal end of the catheter tube while reducing undue twisting of the remainder of the catheter tube.

    摘要： Spiral-wound materials, spirals, and shafts made therefrom that have wraps with edges that may nest within one another are described. Such edges allow the spiral to achieve a smaller bending radius, meaning tighter turns and more flexibility due to the ability of adjacent wraps to nest within each other when the shaft is bent. Spirals having wraps with edges capable of nesting can be used in the medical field for devices that track anatomy, such as endoscopes, colonoscopes, catheters, and the like.
