Abstract: A method of treatment comprises intravascularly securing an anchor extending from an anchor member at least partially within a vessel lumen such that blood flows unobstructed through or past the anchor. While the anchor is secured, a distance of the anchor member, between the anchor and a barrier or membrane projecting distally from a deployment catheter, is adjusted such that an open area defined by the barrier or membrane is placed against or adjacent to a portion of a patient tissue. Adjusting the distance of the anchor member comprises moving the deployment catheter distally with respect to the anchor member. The method also comprises displacing blood with a transparent fluid from the open area, and while the anchor is secured, articulating the barrier or membrane circumferentially around the anchor. The method also includes treating the tissue while visualizing through the transparent fluid.

Abstract: The present invention relates, generally, to reporting the approximate three-dimensional orientation of the steerable distal portion of an endoscope to the user of the endoscope. More particularly, the present invention relates to a system and method for providing the endoscope-user a display from which to more easily determine the approximate three-dimensional orientation of the steerable distal portion of the endoscope, thereby facilitating navigation of the endoscope. The present invention also relates to a system and method for limiting the amount the steerable distal portion can bend overall to reduce or eliminate the user's ability to over-retroflex the steerable distal portion of the endoscope.

Abstract: A side-viewing endoscope includes an elongated tube for entry in a body cavity for imaging. A wire line is contained in the elongated tube, for moving in an axial direction back and forth. A guide device is coupled with a distal end of the wire line, caused to shift between first and second positions by the wire line, for orientation in a direction crosswise to the axial direction upon being set in the second position. An input lever is disposed at a proximal end of the wire line, for moving the wire line in the axial direction. A cam mechanism is connected between the input lever and the wire line, for shifting the guide device at a first shift between the first position and an intermediate position, and shifting the guide device at a second shift smaller than the first shift between the intermediate and second positions.

Abstract: Medical devices are described and illustrated herein. In particular, steerable guide members and catheters useful in the identification and treatment of bodily passages are provided. Methods of identifying and treating bodily passages are also provided.

Abstract: A method of inhibiting tissue migration comprises positioning an open area of a hood against or adjacent to a tissue region. The method also comprises displacing an opaque fluid with a transparent fluid from the open area. The method includes engaging a portion of the tissue region within the open area via an end effector advanced through the open area and which grasps onto the portion. The end effector includes a tapered section, tapered along its entire length, through which a lumen extends. The tapered section includes threads extending from a surface of the tapered section in a direction orthogonal to the longitudinal axis. The tissue region is pierced while displacing the opaque fluid with the transparent fluid through the distal opening of the hood and while maintaining engagement of the portion of the tissue region such that distal movement of the tissue is inhibited.

Abstract: An articulated tip part (3) for an endoscope (1). The articulated tip part (3) comprises a distal end segment (4), a proximal end segment (6) and a number of intermediate segments (5) arranged between the distal end segment (4) and the proximal end segment (6). Each intermediate segment (5) comprises a first passage (8) adapted to accommodate and support an outer wall (11) of a tube (9) providing a working channel of the endoscope (1).

Abstract: An endoscope includes a flexible tube having a curved part at a tip and an endoscope main body part operating a curving operation on the curved part for work, the endoscope having a treatment tool insertion part for inserting a treatment tool projecting from the endoscope main body part and for use in a treatment of a subject into a treatment tool insertion tube arranged in the curved part along an axial direction, wherein the treatment tool insertion part includes an attachment and removal part having an insertion tube and a body, the insertion tube having one end inserted in the endoscope main body part to be arranged to communicate to the treatment tool insertion tube and another end placed outside the endoscope main body part, and the body holding and fixing the insertion tube to the endoscope main body part.
