An intraluminal catheter which provides access to distal locations within a patient's body lumen and which is provided with a flexible distal section having an inner lining, an outer jacket or coating and a helical coil between the lining and jacket. The distal section of the catheter is quite flexible yet it has sufficient transverse or radial rigidity to prevent significant distortion of the transverse cross-sectional shape of the catheter.

Catheter providing intraluminal access

A dilatation catheter assembly which has a dilatation catheter with a sheath mounted on the catheter shaft having an inner lumen extending in the distal portion of the sheath which is configured to slidably receive at least a portion of the dilatation balloon on the distal end of the catheter. The position of the sheath is fixed with respect to the catheter, e.g. a friction fit or bonded in some manner, before the assembly is inserted into the patient's vasculature with the distal portion of the sheath covering a portion of the balloon but leaving a portion of the balloon uncovered with a length equal to the stenotic region to be dilated so that the entire stenosis can be dilated at the same time. The distal portion of the sheath is preferably formed of a flexible polymeric tube with inelastic reinforcement to prevent substantial expansion thereof when the balloon is inflated.

Sheath for an adjustable length balloon

This is a percutaneous medical device and related methods for its use. More particularly, it is a percutaneous catheter having ends which are interchangeably capable both of distal introduction into a delivery device lumen or body space and of proximal coupling to other medical devices.

Bi-directional catheter

A dilatation catheter having a balloon with an inflated length than can be adjusted according to the length of stenosis to be dilated. In one embodiment an exterior sheath having an expandable distal tip is employed about a elongated balloon which can be longitudinally adjusted so as to expose a length of balloon which provides a working balloon length required to dilate the stenosis. In another embodiment, the balloon has independently inflatable chambers. In yet another embodiment, the balloon has longitudinal tubular sections which expand sequentially higher pressures. Other means are also described.

Adjustable length balloon catheter

An intravascular catheter such as a dilatation catheter for angioplasty procedures having a removable distal shaft section. The catheter construction allows the original distal shaft section of the catheter to be removed and a replacement distal shaft section to be secured to the proximal section which is useful with angioplasty catheters when the dimensions of the balloon on the original distal shaft section are inappropriate for dilating a particular stenotic region. Such catheter construction is also useful when there is a need to implant a stent into a dilated stenotic region to maintain its patency.
