A medical system includes an insertion device including a delivery shaft with an internal lumen, a coupling tube coupled to the delivery shaft and configured to receive a medical device, and a liner tube inserted through the internal lumen of the delivery shaft.

The present disclosure relates to an endotherapy camera coupler. The coupler may detachably couple an endotherapy eyepiece cap to a camera and may support a drape for covering the camera. In one example, the coupler comprises an optically transmissible and liquid impermeable member configured to be arranged in an optical path between the eyepiece cap and the camera, a base holding the optically transmissible and liquid impermeable member in the optical path, a receiving portion for the eyepiece cap, wherein the receiving portion comprises a base-side receiving portion configured to receive the eyepiece cap along an insertion path extending in one direction, and a liquid barrier provided in the receiving portion and configured for hindering or preventing liquid from entering between the eyepiece cap and the optically transmissible and liquid impermeable member when the eyepiece cap is coupled to the camera. Other examples of devices and methods of use are described.

A controller for use with a hollow endoscopic needle for collecting tissue, cell and/or fluid specimens from a patient that includes an outer body enclosing a slidably retaining a spring loaded plunger, a click and release plunger holder, a vacuum port, and a hollow needle attached to the plunger that is slidably retained in an outer tube or sheath. The controller permits a surgeon to positively control the needle and penetrate tissue, to pulse the needle, and to quickly and positively return the plunger and its needle back to its original un-pushed position. A vacuum or fluid pathway is defined between proximal and distal seals and along the needle's exterior and the interior of the outer tube or sheath and leads to a distal end of the hollow needle. A stylet can be slidably retained within the hollow needle, and can include a sensor to permit navigation.

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.

The system comprising an internal unit (10) comprising two arrays of N transmitter and N receiver antennas (11R, 11T) for transmitting a microwave signal(s) to one or more body tissues of a patient and for detecting a scattered microwave signal(s) by said one or more body tissues; feeding and multiplexing means (12) in connection with said N transmitter and N receiver antennas (11T, 11R) and with an external computing unit (20) configured to receive said scattered microwave signal(s) and convert it/them into an image, wherein the feeding and multiplexing means (12) provide, under the control of a controller (21) of the external computing unit (20), a continuous sequential selection of different pairs of transmitter and receiver antennas (11T, 11R) to perform the transmission of the microwave signal(s) and the detection of the scattered microwave signal(s).

A method of performing minimally invasive surgery includes inserting an access port through the skin of a patient and positioning the access port so that a distal end of the access port enters or is in contact with an intervertebral disk. An instrument is inserted through the access port such that a distal end portion of the instrument extends into the intervertebral disk, and the instrument is manipulated to pass a shaft portion of the instrument through at least a portion of a slot of the port.

An endoscope accessory, such as a coupler device, is provided that includes a main body with a visualization section for allowing viewing of tissue by the endoscope and a proximal end configured for attachment to a distal end portion of the endoscope. The device includes a passage within the main body having an exit portal and a proximal end aligned with the working channel of the endoscope. An instrument passing through the passage is capable of angular adjustment relative to the main body of the coupler device by actuation of the endoscope.

The present disclosure describes an improved endoscopy scope mask and related methods. One such endoscopy mask comprises a mask body defining an interior cavity that fits over a nose and mouth of a patient, in which the mask body comprises a nasal port in fluidic communication with the interior cavity having a silicone membrane that allows for insertion of an endoscopic instrument; an oral port in fluidic communication with the interior cavity having a soft silicone membrane that allows for insertion of the endoscopic instrument; an oxygen port in fluidic communication with the interior cavity; one or more filtered exhalation ports in fluidic communication with the interior cavity; and a suction port in fluidic communication with the interior cavity, the suction port having a connector for attachment to a suction tool. Other embodiments are also provided.

Lumen fluid conducting and endoscope coupling adaptor for insertion through a lumen entry into a lumen of a patient, comprising: a proximal external body-recliner; a protruding muzzle coupled to the recliner which penetrates through the lumen entry into the proximal portion of the lumen; a collapsible clutch disposed at the distal end of the muzzle, configured to assume an expanded stat in the lumen for fixating the adaptor; a longitudinally extending endoscope bore allowing insertion and retraction of an endoscope through the adaptor; and a lumen fluids conduction arrangement, comprising: a longitudinally extending conduit in fluid communication with the endoscope bore; a fluid suction port in fluid communication with the conduit for releasing fluids from the lumen; a proximal seal for preventing outward leakage of the lumen fluids; and a lumen seal for preventing backflow of lumen fluids by sealing the gap between and protruding muzzle and the lumen.

A stylet for use with a suction system and with an endotracheal (ET) tube configured for insertion into a patient airway in an intubation procedure. The stylet has a semi-rigid elongate tube portion and is configured for removable insertion into the ET tube. An inlet is located at a first end of the stylet and an outlet is located at a second end of the stylet. A suction interface located at the second end of the stylet interfaces with the suction system. The stylet is configured such that a suction pressure created within the suction passage by the suction system suctions substances located within the patient airway into the stylet via the inlet, through the suction passage, and then out of the stylet via the outlet.
