Anchored PTCA balloon

A system for anchoring a device to a lesion in the vasculature of a patient, which comprises:

• a flexible member defining an axis and having an inner surface and an outer surface, with said member having a plurality of solid protuberances projecting radially outward from said outer surface, wherein said member and said protuberances are seamlessly interconnected and are made of a same selected material;
• a balloon en a ed with said inner surface of said flexible member for moving said member between a first configuration, wherein said member is collapsed onto the axis, and a second configuration, wherein said member is substantially rigid and is distanced from the axis;
• a longitudinally oriented cutting initiator formed on each said protuberance for penetrating said protuberances into the lesion;
• and
• a means for projecting said protuberances radially away from the axis to penetrate said protuberances into the lesion and anchor the device to the lesion.

A system for anchoring a device to a lesion in the vasculature of a patient, which comprises:

• a tubular-shaped flexible member having a first end and a second end and defining an axis, said member having an inner surface and an outer surface, wherein said outer surface is formed with a plurality of solid integral protuberances longitudinally oriented and seamlessly interconnected therewith to project radially outwardly therefrom;
• a balloon engaged with said inner surface of said flexible member for moving said member between a first configuration wherein said member is collapsed onto the axis and a second configuration wherein said member is made substantially rigid;
• and
• a means for embedding said protuberances into the lesion and for anchoring the device to the lesion.

A system for anchoring a device to a lesion in the vasculature of a patient, which comprises:

• a flexible member defining an axis and having an inner surface and an outer surface, wherein said outer surface is formed with a plurality of solid integral protuberances longitudinally oriented and seamlessly interconnected therewith to project radially outwardly therefrom, said protuberances being a plurality of raised ridges with said ridges oriented substantially parallel to the axis;
• a balloon engaged with said inner surface of said flexible member for moving said member between a first configuration wherein said member is collapsed onto the axis and a second configuration wherein said member is made substantially rigid;
• and
• a means for embedding said protuberances into the lesion and for anchoring the device to the lesion.
