    Abstract: A balloon catheter is provided to minimize curving of the balloon when the balloon is expanded with an inflation media. The balloon catheter has an elastic inner shaft that stretches longitudinally as inflation pressure in the balloon is increased. The balloon catheter may also have an inner shaft with a portion that is corrugated to allow longitudinal stretching of the inner shaft.

    Abstract: A balloon catheter assembly comprises an elongate catheter shaft having a proximal portion and a distal portion, and an inflatable balloon secured to the shaft distal portion. A plurality of cutters are arranged along an outer surface of the balloon. The cutters are shielded by folds of the balloon when the balloon is uninflated, and are arranged and configured to facilitate breakdown of a vascular restriction when said balloon is inflated. Preferably, the cutters are arranged in at least three generally parallel longitudinal rows along the balloon outer surface, and there are at least three longitudinally-aligned cutters in each row. Preferably, the cutters are formed of the same or a similar base composition as the balloon, and are bonded to the balloon outer surface.

    Abstract: An apparatus for percutaneous catheterization. The apparatus comprises a catheter, and an inner cannula received within the lumen of the catheter. The inner cannula has a distal portion that tapers toward the distal end, and is sized to extend through the distal opening of the catheter to provide a generally smooth diametrical transition between the distal end of the catheter and the distal open end of the inner cannula. A stiffening cannula is sized to be received in the lumen of the inner catheter, and has an inner diameter sized to receive a wire guide therethrough. The stiffening cannula as a distal section of greater flexibility than the flexibility of a proximal section for providing kink resistance to the apparatus.

    Abstract: In at least one embodiment of the present invention a balloon catheter is provided. The balloon catheter comprises a shaft having a lumen formed therethrough. Connected to the shaft is an inflatable balloon. The inflatable balloon has a balloon wall defining a balloon interior surface and a balloon exterior surface that is opposite the interior surface. In fluid communication with the balloon wall is the lumen for inflating the balloon to define an inflated state and for collapsing the balloon to define a deflated state. The balloon wall is textured in the deflated state such that the balloon interior surface is spatially registered with the balloon exterior surface. The balloon in the inflated state is tensioned to have a surface roughness substantially less than a surface roughness of the balloon in the deflated state.
