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: This invention provides a pressure sensing catheter, and method for using the same, which eliminates the practitioners' need to fill the catheter with fluid manually prior to insertion, and thereby increases the accuracy and ease of the overall pressure-sensing procedure. The illustrative catheter includes, in its proximal end, a transducer base or housing that is permanently attached to the catheter shaft. The base includes, inserted thereinto, one or more miniaturized pressure transducer assemblies, which are in fluid communication with corresponding pressure lumens that extend down the shaft and are in communication with one or more predetermined balloons by discrete channels or ports, which provide a fluid passage between the interior space of the balloon and the corresponding pressure lumen. The integral assembly includes a predetermined, previously installed charge of fluid that extends from the transducer, through the corresponding pressure lumen and into the interior volume of the sensing balloon. The charge of fluid has been made free of any air bubbles at the point of manufacture, and is delivered fully charged, so that maximum sensing accuracy and minimum setup time are achieved. In alternate embodiments the catheter can include a fluid infusion/flushing lumen and port interconnected to a proximal fluid connection.

Abstract: An integrated catheter tip that is fabricated to include an inflation balloon that is formed/bonded to the catheter tip as part of an initial molding operation. A tip portion of the integrated catheter tip is formed of a first high durometer polymer while the inflation balloon is formed using a second low durometer polymer. Utilizing a two-step molding operation, the first high durometer polymer can be injected to form the catheter tip and subsequently allowed to cool. Next, the second low durometer polymer is injected to form the inflation balloon and to bond the inflation balloon to the catheter tip so as to create an integrated catheter tip. Once the integrated catheter tip has been formed, the integrated catheter tip can be attached to a catheter body utilizing a conventional attachment method.

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.
