Abstract:
Systems, methods, and devices for delivering ablation fluid to a location of interest within a body (e.g., a location with the lung) are described herein. Ablation fluid delivery systems and devices can include flexible delivery needles (2010) within which a plurality of smaller flexible needles (2040) is housed. The smaller flexible needles can be configured to articulate or bend with respect to the flexible delivery needle to increase an effective delivery area for the ablation fluid. The smaller flexible needles can include apertures or other openings (2042) to facilitate delivery of the ablation fluid to the location of interest.
Abstract:
An apparatus including a housing, an electrical conductor, and a suction control valve. The housing forms a handle and a shaft. The housing defines a suction channel from a distal end of the shaft: The electrical conductor extends to the distal end of the shaft. The suction control valve is connected to the suction channel at the handle. The suction control valve includes a valve body having a first channel and a second channel connected to the first channel, where the first channel forms a portion of the suction channel; and a valve barrel rotatably connected to the valve body. The valve barrel includes a rotatable ring extending around the handle and forming a portion of the housing. The ring includes an orifice configured to be rotated into and out of registration with an end of the second channel as the ring is rotated about the valve body.
Abstract:
A microdebrider (2) comprising; {a) a handpiece (4); (b) an interchangeable tip (10) connected to the handpiece: (c) an outer tube (16) rotatably connected to the interchangeable tip, the outer tube including an outer tube window (18); (d) an inner tube (12) extending at least partially through the outer tube, the inner tube including an inner tube window (14); (e) a lock selector (24) connected to the inner tube; and (f) a bias device (26); wherein the bias device is movable, and upon movement of the bias device into contact with the lock selector the inner tube is immobilized so that the inner tube window is aligned with the outer tube window, aligned with a wall of the outer tube, or in a condition therebetween.

Abstract:
A surgical device comprising: a handle assembly; a locking collar, and a set of replaceable bits that load along an axis into the handle assembly; wherein the locking collar is fully removable from the handle assembly, the locking collar loads axially to a first position, and the locking collar rotates between the first position and a second position; wherein, in the first position, the locking collar is free to be axially removed from the handle assembly and the replaceable bits are free to be loaded or unloaded from the handle assembly; wherein, in the second position, the locking collar is prevented from axial movement relative to the handle assembly and the replaceable bits are revented from being received within, or removed from, the handle assembly; and the Locking collar is guided to the first position and between the first position and the second position by a groove in the handle assembly mating with a member carried by the locking collar.

Abstract:
Imaging apparatus, including an imaging unit (18, 44), which consists of an image sensor (56), configured to capture images of a region and to output image signals in response to the captured images and an illumination source (72), configured to illuminate the region. The unit further includes a driver circuit (80), which is coupled to receive a digital value indicative of a target luminous flux of the illumination source and to generate a pulse-width-modulated (PWM) signal to drive the illumination source with a duty cycle of the signal determined by the value. The apparatus includes a camera control unit (14), which is configured to process the image signals so as to generate images of the region and to output the digital value indicative of the target luminous flux based on the images. A single cable (50) connects the imaging unit to the camera control unit.
