Imaging apparatus, atherectomy devices, systems, and methods of operation thereof are disclosed. The imaging apparatus further comprises one or more light transmittable windows defined along the dividing layer and a catheter outlet port defined along a ventral side of the catheter body. The catheter outlet port allows the guidewire to advance out of the second catheter lumen and the catheter outlet port is aligned with at least one of the light transmittable windows such that the guidewire is within a field of view of the imaging component when the guidewire extends partially though the catheter outlet port. The atherectomy device can comprise a tubular housing and an inflatable balloon coupled to an exterior side of the tubular housing. The tubular housing includes a cutting window and a rotatable cutter configured to debulk the atherosclerotic material extending into the cutting window. The inflatable balloon can comprise a lumen in fluid communication with the housing lumen such that fluid introduced into the housing lumen via the catheter lumen inflates the inflatable balloon.

Apparatus and methods are provided for performing a medical procedure using a stapler apparatus including a reusable handle portion including a shaft include proximal and distal ends, a disposable end effector attached to the distal end of the shaft of the reusable handle carrying one or more staples. For example, the end effector may include first and second jaws movable relative to one another between open and closed positions, the first jaw carrying a cartridge which includes the one or more staples. A Doppler sensor, cutting element, thermal element, and/or grasper may be provided on the end effector. The end effector is introduced into a patient's body, tissue is positioned/locked between the jaws, and a plurality of staples are deployed into the tissue. The Doppler sensor is used to confirm that blood flow has discontinued in the stapled tissue, and the cutting element is actuated to sever the stapled tissue.

A medical device may comprise a handle portion; an insertion portion having a proximal end portion at the handle portion, wherein the insertion portion includes a lumen therein and a distal end having a distal opening in communication with the lumen; and a member disposed within the lumen, the member having a distal end portion with an imaging device. The member may be configured to transition between a first configuration and a second configuration. In the first configuration, the imaging device may face distally, and, in the second configuration, the imaging device may face proximally. Extending the distal end portion of the member distally past the distal opening may cause the member to transition from the first configuration to the second configuration.

A system and method for displaying an endoscope image in a preferred orientation. An endoscope scans a sample with spectrally encoded light by rotating imaging optics inside an endoscope guide. A processor generates an image based on light returned from the sample, and rotates the image by a first angle offset value and a second angle offset value to display the rotated image in the preferred orientation. The first offset value is an angle difference between a specific direction in which the image is to be displayed on a display and a direction in which the tip of the endoscope is oriented with respect to the imaging plane. The second offset value is an angle difference between a direction of the line of scanning light projected onto a plane perpendicular to the tip and the specific direction in which the image is to be displayed.

A medical system comprises an entry guide, a display, and a processor. The processor may be configured to receive state information for an articulatable image capture device controllably extendable out of a distal end of the entry guide. The processor may be configured to generate a view including a graphical representation of a distal end portion of the articulatable image capture device as determined from the received state information and a graphical representation of a field of view of the articulatable image capture device extending distally from the distal end portion of the articulatable image capture device. The processor may also cause the view to be displayed on the display.

The subject matter discloses a multi-sensor endoscope having a dynamic field of view comprising an elongated shaft terminating with a tip section; a maneuvering section connected to the elongated shaft; at least two sensors, wherein at least one sensor is placed behind the tip section, on the maneuvering section; and one or more illuminators located on external surface of the shaft. In some cases, the sensors include a camera. The subject matter also discloses a multi-sensor endoscopy system comprising an endoscope comprising a handle and a controller, such that the maneuvering section is controlled by the controller.

There is provided an endoscope of which a structure is simple and co-rotation of an external cable can be prevented.

A fixing member to be rotated integrally with a knob in a direction around an axis is disposed in an operation unit body, and a part of a light guide in a longitudinal direction is fixed by a fixing part of the fixing member. A light guide-insertion space is formed between the fixing part and a distal end-side opening portion in the operation unit body. A light guide is inserted into and disposed in the light guide-insertion space so that tension is not applied to the light guide present between the fixing part and the distal end-side opening portion even in a case where the fixing member is rotated in the direction around the axis by the knob.

A single solid-state image sensing device is disposed for a first optical system and a second optical system provided in a rigid endoscope. The first image formed by the first light beam emerging from the observation target and passing through the first optical system and the second image formed by the second light beam emerging from the observation target and passing through the second optical system are formed on the imaging surface of the solid-state image sensing device. The solid-state image sensing device then converts the first image and the second image into electric signals. In the picture display unit, the first picture corresponding to the first image and the second picture corresponding to the second image are displayed on the display surface based on the electric signal obtained by the solid-state image sensing device.

A control device includes an image quality control unit configured to control image quality of an image for display on a basis of optical axis angle information with reference to a scope axis of an endoscope and an image signal acquired by an image sensor. The optical axis angle information is information detected by information obtained by acquiring light source angle information controlled by an imaging device.
