Abstract: A rotatable surgical instrument, system, and method includes an outer tubular member and an inner tubular member contained, at least in part, within the outer tubular member and configured to rotate relative to the outer tubular member. A distal tip is coupled to and configured to rotate with the inner tubular member, the distal tip forming a channel around a portion of the distal tip. A bearing is rotatably positioned within the channel, wherein the channel inhibits radial and axial movement of the bearing, with respect to the distal tip, along a major axis of the outer tubular member and inner tubular member, and wherein the bearing is configured to inhibit deflection of the distal tip from the major axis.

Abstract: An endoscope can include an elongated endoscope body. An optical fiber can extend along the endoscope body. The optical fiber can direct therapeutic light and illumination light longitudinally along the optical fiber to a distal portion of the endoscope body. The therapeutic light and the illumination light can have different wavelengths. A wavelength-sensitive light separator, disposed at a distal portion of the optical fiber, can direct the illumination light to exit the optical fiber laterally through a lateral side of the optical fiber at the distal portion of the optical fiber and permit the therapeutic light to exit the optical fiber longitudinally through a distal end of the optical fiber. Examples of suitable wavelength-sensitive light separators can include one or more fiber Bragg gratings that can be obliquely angled, or a diffraction grating disposed on a lateral edge of a length of coreless fiber.

Abstract: An end effector assembly of a forceps includes a first jaw with a tissue sealing surface and an electrode on the sealing surface, and a second jaw with a tissue sealing surface and an electrode on the sealing surface. The first jaw and the second jaw move between an open position and a closed position. The sealing surface of at least one of the first jaw and the second jaw has a rigid medial section and flexible lateral sections.

Abstract: An endoscope body of an endoscope can include a handle, a shaft extending distally from the handle, and a distal portion at a distal end of the shaft. The handle can include a light guide that can receive illumination from a light source that is separate from the endoscope body. The light guide can include an illumination splitter that can split the received illumination into a target illumination and a handle illumination. The light guide can propagate the target illumination to the distal portion to illuminate a target. The distal portion can optionally include a camera that can capture an image of the illuminated target. The illumination splitter can propagate the handle illumination to illuminate at least a portion of the handle, such as an instrument port that can provide access to a proximal end of an instrument sheath that extends to the distal portion.

Abstract: An electrosurgical assembly that includes one or more electrodes, and one or more AC conductors electrically connecting the one or more electrodes to a power source that is configured to generate and output an AC power signal to the one or more electrodes via the one or more AC conductors. A rectifier is electrically connected to the one or more AC conductors, and configured to convert the AC power signal into a DC power signal. A light source is electrically powered by the DC power signal.

Abstract: A surgical needle comprising: (a) a sensor; (b) a distal tip with the sensor being located at the distal tip; (c) a needle advancing mechanism that is adjustable to change an insertion depth; and (d) a control unit in communication with the needle advancing mechanism; wherein the sensor provides a signal to the control unit regarding a thickness of a feature of interest and the control unit controls the insertion depth based upon the signal from the sensor so that the insertion depth into the feature of interest is varied or the control unit prevents the needle advancing mechanism from activating.

Abstract: A surgical device comprising: (a) a first jaw; (b) a second jaw opposing the first jaw, the first jaw, the second jaw, or both being movable relative to one another between a jaw nominal position and a jaw clamped position; (c) a clamp lever in communication with the first jaw and the second jaw, the clamp lever moving the first jaw, the second jaw, or both from the jaw nominal position to the jaw clamped position when an external force is imparted upon the clamp lever in a first direction; and (d) a stop bias member that stops movement of the clamp lever when the external force is removed so that the first jaw and the second jaw are in the jaw nominal position at rest; wherein the first jaw and the second jaw are movable from the jaw nominal position to a jaw spread position when the clamp lever is moved in a second direction that opposes the first direction by an external force deforming the stop bias member so that a distance between the first jaw and the second jaw is larger in the jaw spread position than in the jaw nominal position.

Abstract: Various disclosed embodiments include illustrative apparatuses, medical systems, and methods for attaching two dissimilar materials. In an illustrative embodiment, an apparatus includes a first rod formed from a first material and a second rod formed from a second material. The first rod includes a first end defining a cavity exposed at an end of the first rod. The cavity has a cavity length and a cavity width perpendicular to a longitudinal axis of the first rod. The cavity length is greater than the cavity width. The second rod includes a first section and a second section. The first section has a width that corresponds to the cavity width and a length that corresponds to the cavity length. The apparatus includes a bonding structure that attaches the first rod to the second rod.

Abstract: Various disclosed embodiments include illustrative apparatuses, systems, and methods for injecting medicant into target tissue. In an illustrative embodiment, an illustrative apparatus includes a distal end, a proximal end configured to engage a delivery catheter, and a plurality of flexible bands that extend from the distal end to the proximal end. The flexible bands exhibit a delivery configuration and a deployed expanded configuration. When the plurality of flexible bands are in the deployed expanded configuration a cavity is formed and a medicant receivable via the delivery catheter is disbursable into the cavity.
