Several embodiments of the present invention are generally directed to medical visualization systems that comprise combinations of disposable and reusable components, such as catheters, functional handles, hubs, optical devices, etc. Other embodiments of the present invention are generally directed to features and aspects of an in-vivo visualization system that comprises an endoscope having a working channel through which a catheter having viewing capabilities is routed. the catheter may obtain viewing capabilities by being constructed as a vision catheter or by having a fiberscope or other viewing device selectively routed through one of its channels. The catheter is preferably of the steerable type so that the distal end of the catheter may be steered from its proximal end as it is advanced with the body. A suitable use for the in-vivo visualization system includes but is not limited to diagnosis and/or treatment of the duodenum, and particularly the biliary tree.

A clamp having at least first and second elongate clamping portions adapted to be placed on opposite sides of the hollow anatomical structure. The first and second elongate clamping portions respectively include ends coupled together with respective resilient urging members configured to urge at least one of the first and second elongate clamping portions toward the other of the first and second elongate clamping portions from an open position into a clamping position to occlude the hollow anatomical structure. The clamp includes tissue ingrowth structure on the clamping portions.

Apparatus and methods for occluding a hollow anatomical structure

Systems for delivering a bifurcated stent to a bifurcation site include catheters and/or bifurcated systems delivered therefrom. A catheter includes a balloon with a bulge region that allows a portion of the stent to be expanded.

Bifurcated stent and delivery system

The present invention is directed to features and aspects of an in-vivo visualization system that comprises a catheter having an access port leading to an interior lumen through which an image transmission member is routed, and an endoscope having an access port leading to an interior lumen through which the catheter is routed. The catheter and endoscope are connected by an endoscope attachment device such that a handle of the catheter is mounted distal of the endoscope access port and the catheter access port is distal to the mounted position.

Medical visualization system with endoscope and mounted catheter

Systems for delivering a bifurcated stent to a bifurcation site comprise catheters and/or bifurcated stents delivered therefrom.

A bifurcated stent includes a first stent section and a second stent section. The first stent section is balloon expandable, has an unexpanded configuration, an expanded configuration, and a tubular wall defining a secondary opening. The secondary stent section is self-expanding and an end of the secondary stent section is engaged to a portion of the tubular wall of the primary stent section defining the secondary opening. The secondary stent section has an unexpanded configuration with a first length and an expanded configuration with a second length where the first length is less than the second length. The secondary stent section is expanded to the expanded configuration after the primary stent section is expanded to the expanded configuration. The secondary stent section forms a portion of the tubular wall of the primary stent section in the unexpanded configuration.

A conduit is provided to provide a bypass around a blockage in the coronary artery. The conduit is adapted to be positioned in the myocardium or heart wall to provide a passage for blood to flow between a chamber of the heart such as the left ventricle and the coronary artery, distal to the blockage. The stent is self-expanding or uses a balloon to expand the stent in the heart wall. Various attachment means are provided to anchor the stent and prevent its migration.

A medical instrument including a ductal access device comprising a low profile, ergonomic manifold hub usable to introduce fluids into a breast duct and collect ductal fluid samples including ductal epithelial cells and clumps of ductal epithelial cells from within a breast duct. The ductal access device also comprises an elongated access catheter having a distal end, one lumen and dimensions which permit introduction of the distal end through a ductal orifice so that a distal end of the catheter may be positioned distal to the ductal sphincter of a human breast. The medical instrument may also include and activate valve and a Nitinol introducer.

Ductal lavage microcatheter with user activated valve and Nitinol introducer

The radially expandable frame utilized during catheterization includes a guide wire, a radiopaque radially expandable frame with distal and proximal frame ends wherein the guide wire freely passes through the proximal frame end, an elongated actuation sleeve having a flexible distal end piece (coil strain relief) through which freely passes the guide wire, and a friction locking mechanism located at the proximal end of the system which is defined by the proximal ends of the actuation sleeve and guide wire. The expandable frame includes radiopaque frame struts and has a closed, radially compact form and an open, radially expanded form. The actuator flexible end piece is a coil which enables the system to flex in excess of 90 degrees. The actuator sleeve, at its proximal end, includes a friction locking mechanism having locking members with respective locking surfaces.

Radiopaque locking frame, filter and flexible end

An emboli filter for deployment in a body lumen to capture emboli entrained in a fluid flowing through the lumen includes a flexible elongated member sized to be passed through the lumen. A filter media is carried on and substantially surrounding the elongated member. The filter media has a first end secured to the elongated member adjacent the distal end. A second end of the filter media has a periphery movable toward and away from the elongated member. Opposing internal surfaces of the filter media define a volume into which emboli may flow through the second end when the periphery is moved away from the elongated member. The emboli are trapped within the volume when the periphery is moved toward the elongated member. An actuator moves the periphery toward and way from the elongated member. The actuator includes a plurality of elastic loops. The loops are biased to an open loop configuration with the loops urging the periphery away from the elongated member. The actuator is adapted to be manipulated by an operator to urge the loops against the bias to a closed position permitting movement of the periphery toward the elongated member without interference from the loops.
