Systems, apparatus and methods are disclosed for medical treatment comprising bone access and dilatation and/or cavity creation or enlargement using a narrow gauge, preferably 11-gauge or smaller, cannula wherein a catheter/expandable element assembly meeting medical protocols is designed, adapted and fabricated to fit through the interior of the associated 11-gauge or smaller cannula.

Apparatus and methods for accessing and dilating bone structures using a narrow gauge cannula

Systems, apparatus and methods are disclosed for medical treatment comprising bone access and dilatation and/or cavity creation or enlargement using a narrow gauge, preferably 11-gauge or smaller, cannula wherein a catheter/expandable element assembly meeting medical protocols for such procedures is designed, adapted and fabricated to fit through the interior of the associated 11-gauge or smaller cannula, and further including apparatus and methods for wrapping and/or folding the expandable element either before or after a procedure to reduce its profile to fit through the cannula.

Apparatus and methods for treating bone structures, tissues and ducts using a narrow gauge cannula system

Apparatus and methods are disclosed for medical treatment comprising bone, tissue or duct dilatation using inflatable dilatation elements together with apparatus and techniques for tensioning, stretching, folding, and/or wrapping the dilatation elements externally as well as in situ to facilitate insertion, positioning and withdrawal procedures.

Apparatus and methods for bone, tissue and duct dilatation

Balloons and balloon catheters with a superior overall combination of distensibility, elastic stress response and strength. The improved properties of the balloons result from the method or process used to form the balloons, as well as the polymeric materials used in said balloon forming process. Additionally, the enhanced combination of properties of the balloons will not be adversely affected by the novel sterilization process contemplated by this invention.

Distensible dilatation balloon with elastic stress response

A balloon dilatation catheter used for percutaneous transluminal coronary angioplasty includes a coaxial construction of an inner tube and an outer tube. The inner tube extends distally beyond the distal end of the outer tube. A dilatation balloon is mounted on the distal end of the catheter and is connected at its proximal end to the distal end of the outer tube and at its distal end to the distal end of the inner tube. The lumen of the inner tube is adapted to receive a guidewire and may permit pressure monitoring and liquid infusion. The annular inflation lumen is defined between the inner and outer tubes. The distal end of the outer tube extends into the balloon and is anchored directly to the inner tube. The balloon may be inflated and deflated through an annular inflation lumen defined between the inner and outer tubes, there being openings in the outer tube within the balloon to communicate the inflation lumen with the interior of the balloon. The catheter displays increased column strength and resistance to axial buckling and balloon bunching by reason of the secure connection between the distal end of the outer tube and the inner tube.

Coaxial PTCA catheter with anchor joint

A balloon dilatation catheter used for percutaneous transluminal coronary angioplasty includes an inner tube and an outer tube. The anchor joint of the inner tube and outer tube is permit distal movement of the inner tube with respect to the outer tube while precluding proximal movement of the inner tube with respect to the outer tube. The outer tube is not immovably secured to the inner tube but, rather, may be slidably disposed on the inner tube. The distal end of the outer tube may be tapered to reduced diameter that permits the tapered portion to move longitudinally with respect to the inner tube. The inner tube is provided with an abutment member against which an abutment surface to the outer tube may abut.
