Abstract: A device for visualizing and providing suction for a surgical procedure in an ear may include a handle, a main shaft extending from the handle, an imaging sensor at a distal end of the main shaft, a light source at the distal end of the main shaft, and a suction shaft extending from the handle. The device may also include a spring coupled with the suction shaft and/or the handle, such that when the suction shaft is advanced in a distal direction and then released, the suction shaft retracts automatically. The suction shaft may have a distal curved portion, and the device may have a thumb depress portion that allows a user to spin the suction shaft to suction in different directions. Some embodiments may include a suction shaft with a sharp distal tip that is configured for placing an ear tube in the tympanic membrane.

Abstract: A device, system and methods for a minimally invasive bypass procedure, includes a graft having a supporting segment, an extending segment and a bypass segment. The supporting segment includes a flexible portion and a supporting member, and the extending segment includes a flexible portion and a supporting member. The extending segment has an initial configuration wherein it is unextended and a final configuration wherein it is extended proximally into the vessel. The bypass segment is positioned outside of the vessel to be treated, and the supporting segment is positioned within the vessel and distal to the incision. Once the supporting segment and the supporting member are anchored in place, the extending segment is extended proximally past the incision site. Thus, the supporting segment and the extending segment are substantially aligned, and allow for blood flow through the vessel while also providing blood flow around an obstruction via the bypass segment.
