A device includes a catheter section comprising a flexible joint region disposed between a distal end and a proximal end. The device includes a laser fiber disposed within the catheter section. The laser fiber emits laser light at a fiber distal end. The device includes a wire comprising a distal end coupled to the catheter section. The wire is configured to move the distal end of the catheter section from a first position to a second position about the flexible joint region.

A therapeutic intubation device may comprise a tube, a first probe channel, a second probe channel, a first probe and a second probe. In various embodiments, a tube may have an elongate body having a proximal end and a distal end. The body may define a first channel between the proximal end and the distal end. A first probe channel may be defined in the body. A second probe channel defined in the body. A first probe may comprise a first body portion and a first end portion, the first end portion comprising a first ultraviolet-c (“UVC”) light emitting device. The first probe may be installable the first probe channel such that the first end portion of the first probe is adjacent the distal end of the tub during operation.

A method for identifying material to be removed from a patient may use an imaging device, a display, a control unit, and an insertion device. The method may include obtaining a first set of image data from the imaging device, sending the first set of image data to the control unit from the imaging device, and analyzing the first set of image data based on at least one of a darkness, a contrast, or a saturation. The method may include generating a coded image identifying the material to be removed from the patient to be displayed on the display. The method may further include displaying the coded image on a first screen of the display, and indicating the material to be removed with the insertion device based on the displayed coded image.

Single injection methods for obtaining conductance measurements within luminal organs using impedance devices. In at least one method embodiment, the method is performed by introducing at least part of an impedance device into a mammalian luminal organ, the impedance device comprising an elongated body and a detector positioned along the elongated body, obtaining conductance measurements indicative of a fluid native to the mammalian luminal organ and indicative of a fluid injection while the detector is present within and outside of the lumen of the outer sheath, and calculating a size parameter of the mammalian luminal organ based in part upon some of the obtained conductance measurements.

A surgical laser system comprises a laser source configured to generate laser energy; a laser fiber optically coupled to the laser source and configured to discharge the laser energy generated by the laser source; a rocker arm configured to control an orientation of the discharged laser energy; and a controller configured to control a movement of the rocker arm in response to feedback of the discharged laser energy or to pre-defined settings of the laser source.

A side-fire laser fiber (102) includes an optical fiber (112) having a distal end (116) and a fiber cap (114). The fiber cap is coupled to the distal end of the optical fiber and includes a molded reflective surface (130) and a sealed cavity (132A or 132B). The molded reflective surface defines a wall of the cavity. Laser energy discharged from the distal end along a central axis (124) of the optical fiber is reflected off the molded reflective surface in a direction that is transverse to the central axis.

The device serves for the controlled conveying of a cable. The device has a housing, having a cover plate, on which are externally mounted a drive wheel and contact wheel which can be radially pressed onto the drive wheel, between which the cable can be clamped. The cable can be conveyed by means of the drive wheel being driven by a drive unit in the interior of the housing. The rotational motion of the drive wheel is guided through a stationary light barrier by means of a counting disc, running synchronously therewith and having radial slots or holes in the circumferential area, for determining the motion and rotational speed of the drive wheel. The cover plate and the housing can be sterilized. The drive unit in the interior of the housing is not sterilizable, yet is completely enclosed by the sterilized housing and cover plate.

An endoluminal lasing system for treating vascular disorders is disclosed. Treatment comprises an elongated member that conveys laser radiation to tissue and a motorized mechanism, through which elongated member is rotated. As motor drives, its movement spins elongated member leading to a spiral movement as physician manually moves member in a longitudinal direction. In a preferred embodiment, elongated member is an optical fiber for endoluminal vessel treatment. In another preferred embodiment optical fiber comprises an off-axis firing distal end or side-firing distal end. Optical fiber can be a radial emitting fiber. Spin velocity can be varied according to treatment needs, i.e., pathology, type of vessel, energy source, vessel diameter, etc. One advantage, spiral movement prevents adherence to vessel wall in treatments. Another advantage is that radiation is applied more uniformly along vessel wall. The vessel wall is, thus more evenly treated under most conditions. Treatment velocity and reproducibility are enhanced with this procedure, and human errors are minimized.
