The present disclosure is directed to a medical device. Systems and methods are provided for utilizing a laser to break a kidney stones into smaller fragments and/or dust, and removing particles, stone fragments and/or stone dust from a patient. The medical device may include a tube having a distal end and a proximal end, a first lumen extending from the proximal end to the distal end of the tube and in fluid communication with the distal end and a plurality of side ports located at a distal portion of the tube, and a second lumen extending from the proximal end to the distal end of the tube.

A baby endoscope which forms a medical device includes: a rotary member; an exterior member which rotatably holds the rotary member about a predetermined rotation axis, houses the rotary member in the exterior member, and has a surface which is brought into contact with a portion of an outer peripheral surface of an operation section of a mother endoscope on an outer peripheral portion; and a bending operation lever mounted on the rotary member, and is disposed within a width of the exterior member in a direction of the rotation axis when the exterior member is viewed in a direction orthogonal to the rotation axis.

A system for modularly assembling a scope device includes an optical module which has an optical housing and a longitudinal member extending distally therefrom. A distal end of the member includes a camera for visualizing a target area, electric wires and a light source extending from the camera to the optical housing. The system also includes a deflector module coupleable with the optical module. The deflector module includes a deflector housing and a deflector shaft extending distally therefrom. The shaft includes a first channel sized, shaped and configured to receive the member therein and a deflectable portion extending along a distal portion of the shaft. The deflector housing includes an actuator for deflecting the deflectable portion, the optical and deflector housings including corresponding connecting elements to engage one another when the member is inserted through the first channel and the deflector and optical housings are coupled.

A piston is inserted into a piston passage of a cylinder. The piston is displaced between a first position of a non-contact state and a second position by a pressing operation. At the first position, a suction source connection port of the cylinder faces a circumferential groove of the piston and a suction source conduit communicates with an outside atmosphere. At the second position, the suction source connection port faces an outer peripheral surface opening and the suction source conduit communicates with a suction connection port. A V-shaped opening portion as a correction opening portion is formed in the outer peripheral surface opening. The V-shaped opening portion causes an increment of a communication opening width at which the suction source connection port overlaps with the outer peripheral surface opening to be three times or less an increment of a pressing stroke of the piston.

There is provided herein a flexible electronic circuit board for a tip section of a multi-camera endoscope, the circuit board comprising a front camera surface configured to carry a forward looking camera, a first side camera surface configured to carry a first side looking camera, a second side camera surface configured to carry a second side looking camera, one or more front illuminator surfaces a configured to carry one or more front illuminators to essentially illuminate the FOV of the forward looking camera, one or more side illuminator surfaces configured to carry one or more side illuminators to essentially illuminate the FOV of the first side looking camera and one or more side illuminator surfaces configured to carry one or more side illuminators to essentially illuminate the FOV of the second side looking camera.

Disclosed are access devices that can be used to safely guide instruments, such as EP ablation catheters, to a therapy site such one within the pericardial space of the heart. The access devices include integrated visualization, illumination, stabilization, and safety features in a single platform that can, for example, more safely and efficiently identify and ablate several ventricular tachycardia (VT) locations on the left ventricle of the heart.

A surgical console includes a drive assembly, vacuum interface, fluid transfer device, user interface, and control circuit. The drive assembly is configured to be coupled to an endoscopic tool and to be rotated by a motor. The vacuum interface is configured to apply a vacuum to the endoscopic tool. The fluid transfer device is configured to flow fluid through the endoscopic tool. The user interface is configured to receive a user input indicating at least one of instructions to rotate the endoscopic tool while applying the vacuum, or to flow fluid through the endoscopic tool. The control circuit controls at least one of the drive assembly, the vacuum interface, or the fluid transfer device based on the instructions, and is configured to cause the drive assembly to rotate the endoscopic tool while the vacuum interface applies the vacuum responsive to the user input indicating instructions to rotate the endoscopic tool.

In some embodiments, an electronic laryngoscope includes a camera, a hollow connecting rod, a handle, and a control display. The front end of the connecting rod is connected to the camera, the rear end of the connecting rod is connected to the handle, and the rear end of the handle is connected to the control display. The laryngoscope further includes a hollow tube whose inner diameter is greater than the outer diameter of the connecting rod. The camera and the connecting rod are located on the inner side of the hollow tube. A sputum suction opening is formed between the front end of the hollow tube and the front end of the camera, and a sputum passage in communication with the opening is formed between the hollow tube and the connecting rod. The laryngoscope further includes a connector between the hollow tube and the camera and/or the connecting rod.

Provided are products of manufacture and methods for the removal and/or destruction of a biofilm in situ, e.g., a gastro-luminal biofilm, and for the treatment or amelioration of biofilm-associated diseases, infections and conditions, including and GI luminal infections. Provided are devices and apparatus, and methods for using them, for the removal, disruption and/or destruction of a biofilm in situ, e.g., a gastro-luminal biofilm. In alternative embodiments, provided are devices and apparatus, and methods, for enhancing biofilm dissolving or disrupting agents, or for administering biofilm dissolving or disrupting agents, where in alternative embodiments the biofilm comprises a gastro-luminal ‘unstirred layer’, adherent layer or gastro-luminal mucus layer; or the biofilm comprises a matrix or a DNA-containing layer, or alternatively the biofilm comprises a polysaccharide gastro-luminal peripheral layer.

The endoscope adapter for obstruction removal attaches to an endoscope via a flexible coupler/collar. The endoscope uses a pump to create suction, the low pressure causing a flow through the adapter. A constriction, or venturi, between the endoscope tip and adapter creates an increase in suction pressure, resulting in an increased effectiveness in gripping and removing obstructions, such as partially-chewed food. The endoscope adapter for obstruction removal includes two primary features: First, the tip is a larger diameter than the coupler, thus increasing the area for gripping the food or bolus. Second, a construction, forming a venturi, between the location where suction is applied by the endoscope, increasing the resulting suction.
