Abstract: An example multi-lumen member forming dual inflation portions of a catheter assembly for treating bifurcated vessels includes a main tube defining a main lumen and a main inflation portion. The member includes a side tube defining a side lumen and a side inflation portion, the side tube extending along at least a first length of the main tube. The member also includes a portion extending along the first length of the main tube and coupling the main tube to the side tube to form a dual lumen configuration.

Abstract: A reinforced composite balloon may comprise a body layer and a reinforcing layer. The reinforcing layer may comprise a single-layer structural network having a plurality of apertures. The reinforcing layer may be molded from a reinforcing tube having a plurality of apertures or aperture precursor holes.

Abstract: Balloon systems for treating bifurcated lumens include desirable burst and folding characteristics. In some cases, the balloon systems can be formed by varying the wall thickness of a balloon parison.

Abstract: A catheter assembly includes a main catheter branch and a side catheter branch. The main catheter branch includes a main balloon, a side balloon and a side inflation member. The side inflation member intersects the side balloon at a location on the side balloon that is offset laterally from a central line passing from a distal most point on the side balloon to a proximal most point on the side balloon. The side balloon is configured to extend radially outward relative to the main balloon when the side balloon is inflated. The side catheter branch can be centrally aligned with the side balloon central line and be positioned laterally adjacent to the side inflation lumen.

Abstract: An implantable medical device and method for adjustably restricting a selected body lumen such as a urethra or ureter of a patient to treat urinary incontinence or ureteral reflux. The device includes an adjustable element and a tubular elongate body, where the adjustable element includes a chamber and the tubular elongate body includes at least a first interior passageway which extends longitudinally in the tubular elongate body from a first opening at the proximal end to a second opening in fluid communication with the chamber. Fluid volume passed through the first passageway is used for adjustably expanding or contracting the adjustable element. The implantable medical device further includes a sheath and a sleeve, where the sheath includes a wall having an inner surface which defines a channel through which at least a portion of the implantable device and the sleeve can pass.

Abstract: A catheter inflatable member forming mold can include first and second frames that mate to define a mold cavity, the mold cavity defining a main cavity portion and a bulge cavity portion, the mold cavity being sized to receive an elongated tube member therein. The mold can also include a pin member with a head portion positioned in the mold cavity, the pin member extending into the mold cavity, the head portion of the pin member being moveable in a first direction to contact and move the tube member towards the bulge cavity portion of the mold cavity during molding.

Abstract: The present subject matter includes an implantable device and method for restoring continence and controlling coaptivity of a body lumen. The device includes a fill port block which has one or more self-sealing septums. The fill-port block is connected to one or more elongate conduits and ultimately to one or more expandable elements for communicating fluid. The one or more expandable elements are implanted and adjusted from a remote location using the fill-port block. Methods for implantation, use, and construction are also provided.

Abstract: A bifurcated stent having a self-expanding side branch assembly and at least one restraining tether. The restraining tether prevents the side branch assembly from expanding until so desired. When desired, the restraining tether is pulled from the side branch assembly allowing the side branch to self deploy. This design allows for the side branch to deploy independent of and before, after, or during the expansion of the main stent body. It also removes any need to coordinate the inflation of multiple balloons or the complicated inflation of irregularly shaped balloons.

Abstract: Apparatus and method for adjustably restricting a selected body lumen such as an anal canal of a patient to passively treat fecal incontinence. The apparatus in various examples comprises a plurality of expandable elements. Each of the elements is comprised of a membrane of biocompatible material enclosing a volume. The elements expand upon introduction of fluid into the elements and contract upon withdrawal of fluid from the elements. The expandable elements are adjustable in size by adjusting an amount of fluid in the elements. Fluid communication to the expandable elements is provided by a plurality of flexible conduits of biocompatible material coupled to both the expandable elements and a fill port block comprising a plurality of fill ports.
