A treatment device to treat a living tissue, includes: first and second holding portions; a rotary member including a working portion including an edge portion which is rotated around a central axis equal to or substantially parallel with the longitudinal axis, the rotary member capable of moving the edge portion from the first holding portion to the second holding portion; a first guide portion provided in the first holding portion and capable of guiding the edge portion toward the second holding portion through the holding surface of the first holding portion; and a second guide portion provided in the second holding portion, and capable of guiding the edge portion to the second holding portion through the holding surface of the first holding portion.

A polyp removal device comprises an outer tubular body; an inner tubular body being movable with respect to the outer tubular body; a handle; an actuation member configured to cause movement of the inner tubular body with respect to the outer tubular body when the actuation member is moved with respect to the handle; a vacuum port for coupling thereto of a vacuum source; and an opening near a distal end of the polyp removal device, the opening configured to allow fluid communication between an environment external to the polyp removal device and the lumen of the inner tubular body, wherein a size of the opening is variable based on the movement of the inner tubular body with respect to the outer tubular body.

An adjusting and cutting tool including a distal end engageable with an elongate portion of an implantable article to facilitate manipulation of the elongate portion relative to a support portion of the implantable article and to facilitate cutting of the elongate portion. Also included is method of treating vaginal prolapse, the method including the steps of providing a multi-piece implantable article having at least one extension portion piece and a support portion piece, placing the support portion piece in contact with vaginal tissue, placing at least one extension portion piece in contact with tissue of a component of sacral anatomy, adjusting a position of the at least one extension portion piece relative to the support portion piece using a adjusting and cutting tool, and cutting the at least one extension portion with the adjusting and cutting tool.

A surgical device. The surgical device may comprise a transducer configured to provide vibrations along a longitudinal axis and an end effector coupled to the transducer and extending from the transducer along the longitudinal axis. The surgical device also may comprise a lower jaw extending parallel to the end effector. The lower jaw may comprise a clamp face extending toward the longitudinal axis. Also, the lower jaw may be slidable relative to the end effector to bring the clamp face toward a distal end of the end effector.

A catheter for removing tissue from a body lumen and for providing information relating to the body lumen. The catheter includes a tissue cutting element that rotates relative to the catheter body and is mounted to the drive shaft for imparting rotation to the tissue cutting element. As energy emitting element of the catheter rotates relative to the catheter body and is rotatable independently of the tissue cutting element.

Methods and devices for separating an implanted object, such as a pacemaker lead, from tissue surrounding such object in a patient's vasculature system. Specifically, the tissue separating device includes a handle, an elongate sheath and a circular cutting blade that may extend from the distal end of the sheath upon actuating the handle. The elongate sheath, particularly its distal end, includes a non-uniform wall thickness having one or more thicker portions in the outer sheath, particularly the outer cam member, and/or one or more thicker portions in an inner member disposed radially inward of the blade.

An endoscopic surgical device having a windowed blade case featuring an interior surface that is black or dark, provides improved feasibility and ease of use. Further advantages are achieved by flanging the exterior surface of the blade case, and by providing a scraper tip.

A medical cutting instrument for cutting muscles and tendons, having a shaft on whose distal end a tool is mounted consisting of two jaw members, such that one jaw member can be moved with respect to the other jaw member, and on whose proximal end a handle is mounted, such that the movable jaw member and the handle operatively interact by way of an actuation element, in such a way that the movable jaw member can be shifted by actuating the handle between a closed position and an opened position. The other jaw member is U-shaped such that the two parallel legs of the U are disposed diagonally to the instrument longitudinal axis and the opening of the U points toward one side of the other jaw member, so that the other jaw member can be pushed from the side onto the muscle/tendon tissue that is to be severed.

Prosthetic valve systems for replacing a native valve exhibiting regurgitation comprises a support structure and a transcatheter heart valve (THV) that is separate from the support structure. The support structure can be configured to be positioned such that it extends annularly around the native valve leaflets. After the support structure is deployed around the native valve leaflets, the THV can be expanded within the support structure such that the native valve leaflets are engaged between the support structure and the THV.

A surgical instrument includes a hollow member having a sidewall provided with a window and a closure member movably connected to the hollow member for alternately covering and uncovering the window. The hollow member has a first clamping surface along an edge of the window, while the closure member has a second clamping surface opposing the first clamping surface and disposable substantially adjacent thereto in a clamping or closure configuration of the instrument. The instrument additionally comprises a tissue occlusion component mounted to at least one of the hollow member and the closure member for acting on tissues gripped between the first clamping surface and the second clamping surface, to couple the tissues to each other.
