In a shapable catheter and method for positioning a shapable catheter within a body cavity, a core wire is provided which includes a pre-shaped region bent into a predetermined shape. A catheter is provided which includes a lumen proportioned to slidably receive the core wire. The catheter includes a rigid proximal section and a flexible distal section. A pull wire may additionally be provided to allow the user to cause deflection at a distal portion of the catheter.

Shapable catheter using exchangeable core and method of use

A method is provided for forming a stent within a body lumen. According to the method, a distal catheter body is advanced within a body lumen to a section of a body lumen at which a stent is to be formed. One or more expandable members attached to the distal catheter body are expanded such that sections of the body lumen proximal and distal to the stent formation section of the body lumen are occluded, the distal catheter body in combination with the body lumen defining a mold space. A fluent pre-stent composition is delivered to the mold space from outside the body lumen which is continuously in fluent state during pre-stent composition delivery from outside the body lumen to the mold space. The fluent pre-stent composition is then transformed within the mold space to a non-fluent stent composition to form a stent within the mold space.

Method for forming a stent in situ

In a shapable catheter and method for positioning a shapable catheter within a body cavity, a core wire is provided which includes a pre-shaped region bent into a predetermined shape. A catheter is provided which includes a lumen proportioned to slidably receive the core wire. The catheter includes a rigid proximal section and a flexible distal section. During use, the distal end of the catheter is inserted through a patient's vasculature and is passed into a body cavity. The pre-shaped region of the core wire is passed into the lumen and is straightened by the rigid proximal section of the catheter. The pre-shaped region is passed further into the catheter until it reaches the flexible distal region, in which the pre-shaped section re-assumes its predetermined shape and causes the core wire to form the distal section of the catheter into the predetermined shape. The distal section of the catheter is positioned in contact with tissue in the body cavity, and electrodes carried by the distal end are used to map and/or ablate the tissue.
