Abstract: An imaging device includes a grin lens having a proximal end and a distal end, wherein the grin lens is made from a polymeric material, an optical fiber having a distal end coupled to the proximal end of the grin lens, and a beam director coupled to the distal end of the grin lens, wherein the beam director is configured to direct light at an angle relative to a longitudinal axis of the optical fiber.

Abstract: A method of making an axicon includes providing a structure having an axicon-shape cavity, the cavity having a first end and a second end, the first end of the cavity having a cross sectional dimension that is smaller than the second end, placing a polymeric substance into the axicon-shape cavity, and forming an axicon using the polymeric substance.

Abstract: A medical device includes an elongate member having a proximal end, a distal end, a body extending between the proximal end and the distal end, and a lumen located within the body, and a rotor rotatably supported in the lumen, the rotor having an opening for allowing light to pass theretherough, wherein the rotor is rotatable about an axis that extends through the opening, wherein the elongate member further has a region for allowing an output light to exit therethrough.

Abstract: An imaging device includes a grin lens having a proximal end and a distal end, an optical fiber having a distal end coupled to the proximal end of the grin lens, a tube surrounding the optical fiber, wherein the tube is coupled to the optical fiber and includes a plurality of cutouts, and a beam director coupled to the distal end of the grin lens, wherein the beam director is configured to direct light at an angle relative to a longitudinal axis of the optical fiber.

Abstract: A medical device includes an elongate member having a proximal end, a distal end, a body extending between the proximal end and the distal end, and a lumen located within the body. The medical device also includes a tube located inside the lumen, wherein the tube is rotatably supported inside the lumen, a optical waveguide located inside the tube, and a bearing element located in the lumen and disposed between the tube and the body of the elongate member. The elongate member further has a side wall and a region at the side wall for allowing an output light from the optical waveguide to exit therethrough.

Abstract: A device for delivering fluid inside a vessel includes an elongated member having a proximal end, a distal end, and a channel extending between the proximal end and the distal end, and a first port located at the distal end, wherein the first port is in fluid communication with the channel, wherein the first port faces at least partially towards a proximal direction.

Abstract: A device includes a rotor having a proximal end, a distal end, and a body extending between the proximal and distal ends, wherein the rotor has an opening extending from the proximal end, the rotor being rotatable about an axis that extends through the opening, and wherein the rotor has a port with a port axis that forms an angle relative to the axis, the angle having a value that is larger than zero and less than 180°.
