Cardiac ablation catheters and methods of use. Catheters that include an expandable membrane, an imaging member disposed within the expandable membrane, the imaging member having a field of view, a light source disposed within the expandable member adapted to deliver light towards the field of view of the imaging member, and an electrode comprising an outer conductive layer and inner light absorbing layer disposed between the electrode and the expandable membrane, the inner light absorbing layer adapted to absorb light from the light source and thereby reduce reflection of the light from the outer conductive electrode.

A linear drive for a miniaturized optical system, as used for example in an endoscope, includes a stator and an armature. The stator has a coil with two stator pole shoes arranged in axial direction, and two magnetic field sensors arranged at the outer side of the stator pole shoes. The armature has permanent magnets which are polarized in opposite directions, and a center armature pole shoe between the two permanent magnets, and an armature pole shoe at each side of the permanent magnet, opposite to the center armature pole shoe in axial direction. The magnetic field of the outer armature pole shoe goes completely or only in part, dependent from the armature position, through the magnetic field sensor and thus generates a position-dependent signal. This signal can be used for measuring and/or controlling the position of the armature.

The present specification describes a circuit board design that uses circuit boards for illuminator sets associated with the various optical assemblies. In one configuration, front and side illuminators are assembled on front and side illuminator circuit boards. Leaf connectors associated with each illuminator are provided to interface with a common base board.

An integrated clot evacuation device having visualization for use in neurosurgical applications, particularly for the evacuation of clots formed as a result of intracranial hemorrhage (ICH). The device may further include an integrated camera and light for visualizing the interior of the brain and the clot itself. Further, the device is configured to evacuate clots through aspiration and irrigation.

A medical device is used to image a body cavity using a plurality of axially and angularly spaced imaging sensors. Each imaging sensor generates an image that is distinct from one another due to distinct fields of vision. Each image includes an overlapping zone with commonalties that are used to extrapolate a greater calibrated image.

A variable direction of view endoscope system including an endoscope having an image receiver with a variable direction of view adjustable over a viewing range bound by a first limit and a second limit and a single button for adjusting the variable direction of view of the image receiver, wherein actuation of the single button advances the variable direction of view sequentially through the viewing range. When the image receiver is at the second limit of the viewing range, actuation of the single button adjusts the image receiver back to the first limit of the viewing range.

An endoscope includes: a first image acquisition portion configured to acquire a first object image from a first direction; a second image acquisition portion configured to acquire a second object image from a second direction different from the first direction; first illumination light emission portions provided on a straight line with the first image acquisition portion, the first image acquisition portion being interposed between the first illumination light emission portions, and arranged along a line orthogonal to an optical axis of the first image acquisition portion; and second illumination light emission portions lined up and arranged on a plane where the second image acquisition portion is arranged at the insertion portion, and a lining direction of the first illumination light emission portions and a lining direction of the second illumination light emission portions are arranged at positions to be a twisted relation.

A light therapy diagnostic device comprising a shaft, an optical waveguide disposed in a lumen of the shaft and being movable forward and backward in a longitudinal direction of the shaft, and a transparent member disposed in the lumen and located distal to the optical waveguide, wherein: the optical waveguide guides a first light and a second light; the shaft has a lateral emission window which allows the first light and the second light to be emitted toward a lateral direction and a distal emission window which allows the first light to be emitted toward a distal direction; the optical waveguide includes a core and a clad, wherein a distal end surface of the core is inclined with respect to an optical axis of the optical waveguide; the first light passes through the transparent member in a state where the optical waveguide is in contact with the transparent member.

A medical imaging device configured to be inserted to a patient's body, comprising an elongated tube, comprising two or more cameras for capturing visual content in the vicinity of the device in different directions of view, a light source for illuminating a field of view of the two or more cameras, a wireless module configured to transmit data captured by the two or more cameras to a remote devices, and a power source for supplying power to the camera, the light source and the wireless module.

Disclosed is an elongated shaft detachably mountable on a reusable handle of a multi-camera endoscope, The elongated shaft includes a shaft body. The shaft body includes, at a shaft body distal section, at least two cameras and at least one illumination component, and, at a shaft body proximal section, an adaptor. The adaptor is configured to mechanically and electronically detachably couple to a coupling interface on a distal section of the handle, such as to mount the elongated shaft on the handle. The adaptor is further configured to dictate a preferred mounting orientation such that the at least two cameras provide a combined and predetermined at least about 270 degrees horizontal field-of-view (FOV) of a target area within an anatomical cavity when the elongated shaft is mounted on the handle.
