Abstract: A method is used to manufacture a surgical instrument including a first tube, and a second tube. The first tube extends from a proximal first end portion to a distal first end portion. The second tube extends from a proximal second end portion to a distal second end portion. The second tube is positioned coaxially within the first tube with the distal second end portion positioned adjacent to the distal first end portion. The second tube defines a lumen. The sensor is secured proximal to the distal second end portion of the second tube. A die is engaged against a distal first end portion of the first tube while first tube rotates about its own longitudinal axis; and the die is simultaneously moved relative to the distal first end portion of the first tube along a predetermined path to form a predetermined shape.

Abstract: An apparatus includes a body, an upright member, a frame, and a plurality of field generating elements. The body is configured to be positioned between a patient's back and a backrest of a chair. The upright member extends upwardly from the body. The frame has a curved configuration configured to partially surround a patient's head. The field generating elements are configured to generate an electromagnetic field around a patient's head partially surrounded by the frame.

Abstract: An apparatus includes a dilation catheter and a guide catheter. The dilation catheter includes an expandable dilator that is configured to transition between a non-expanded state and an expanded state. The guide catheter includes a hollow shaft and a malleable portion. The hollow shaft and the malleable portion together define a lumen in which the dilation catheter is slidably disposed. The malleable portion is configured to selectively bend relative to the hollow shaft from a first angular configuration to a second angular configuration. The malleable portion is configured to be coaxial with the longitudinal axis in the first angular configuration. The malleable portion is configured to define an angle that is oblique or perpendicular with the longitudinal axis in the second angular configuration. The malleable portion rigid enough to maintain a selected bend angle relative to the hollow shaft while inserted within a nasal cavity.

Abstract: An apparatus includes a cannula and a grip portion. The cannula includes a first lumen extending from a proximal end to a distal end of the cannula. The grip portion is secured to the proximal end of the cannula. The grip portion includes a second lumen, a transversely oriented vent port, a suction port, and a guidewire port. The second lumen is in communication with the first lumen. The transversely oriented vent port is configured to communicate with the second lumen to thereby vent the second lumen to atmosphere. The suction port is configured to communicate with the second lumen to thereby communicate suction to the distal end of the cannula via the first lumen. The guidewire port is configured to receive a guidewire. The guidewire port is further configured to communicate with the second lumen to thereby provide a path for the guidewire to reach the first lumen.
