    Abstract: A catheter assembly (10) includes a main catheter branch (12) and a side catheter branch (14). The main catheter branch includes a main balloon (36), a side balloon (38) and a side inflation member (34). 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: The disclosure describes a device for asymmetrical irradiation of a body cavity or site, such as after removal of tissue, e.g. biopsy or lumpectomy. The device includes an elongated tubular shaft having an inner lumen and a tubular wall with a plurality of lumens extending within the wall which are configured for receiving a radiation source. The distal portion of the tubular shaft is cut into a plurality of longitudinally separated wall segments with a lumen extending within at least one of the wall segments. A support member is positioned within the separated wall segments to support and position the wall segments in a desired configuration for brachytherapy. An expandable member such as an inflatable balloon is mounted on the distal shaft portion about the separated wall segments wall which when inflated secures the distal shaft portion within a desired intracorporeal site for brachytherapy treatment.

    Abstract: A multi-layered balloon is provided where each layer is formed such that each layer is made from tubing that optimizes the inner wall stretch thus providing maximum balloon strength. The high pressure, multi-layer balloon is provided with layers that allow for slipping, such that the balloon has a very high pressure rating and toughness, yet excellent folding characteristics. Methods for producing such multi-layer balloons using existing balloon forming equipment are also provided. The multi-layer balloons can have alternating structural and lubricating layers, or layers with low-friction surfaces. The multi-layer balloons are preferably manufactured using a variety of methods including nesting, co-extrusion, or a combination of nesting and co-extrusion. The multi-layer balloons have balloon layers having substantially similar, or the same, high degree of biaxial orientation of their polymer molecules such that each balloon layer of the multi-layer balloon will fail at approximately the same applied pressure.

    Abstract: A balloon catheter used in PTCA (Percutaneous Translumin Coronary Angioplasty), a catheter shaft for the catheter and a method of production of a balloon. The balloon catheter includes a catheter shaft (1A) comprising a multi-lumen shaft inclusive of a dual lumen tube and a balloon (2) disposed at the remotest end of the catheter shaft (1A). The catheter shaft (1A) is equipped with at least a guide wire lumen (4A) and an inflation lumen (4B), and is made of a resin material having a bending modulus contributing to push force transmission property and curved route follow-up property. A resin material layer (tube (5)) having high lubrication property and surface energy of not greater than 50 dyn/cm is disposed on the inner surface of the guide wire lumen (4A).

    Abstract: A rapid exchange balloon catheter having a proximal end and a distal end, said catheter comprising: a tubular metal shaft body extending from the proximal end along a majority of the total length and having an inflation lumen arranged therein, a plastics distal end portion bonded to the metal body in extension thereof, said distal end portion being provided with an inflation lumen in communication with a balloon, and a guide wire lumen, said guide wire lumen extending from a proximal side port to a distal end opening. To reduce the resistance to kinking, the metal body comprises a transitional region having reduced stiffness at the position of bonding to the plastics distal end portion compared to a more proximal position along the metal body.

    Abstract: A balloon catheter, and method of making the same, which includes an elongated shaft, and an expandable member affixed to the distal portion of the elongated shaft such that a section of the elongated shaft extends through at least a portion of the expandable member. The elongated shaft includes a radiopaque portion that includes a radiopaque material disposed in a non-metallic coating material. In some embodiments, the radiopaque portion is positioned adjacent the expandable member such that the position of at least a portion of the expandable member (or a stent disposed thereon) can be identified or determined within the vasculature in which it is deployed using an appropriate imaging technique, such as fluoroscopy. Additionally, in some embodiments, the radiopaque portion can define one or more raised areas on the elongated shaft adjacent the expandable member. In such embodiments, the raised area or areas in the radiopaque portion can function as mounting bodies for mounting a stent.
