摘要： A catheter assembly comprises a sheath, which includes a side wall enclosing an interior bore, a distal region, and an opening in the sidewall. The assembly also comprises a bendable catheter tube, which is carried for sliding movement in the interior bore. The catheter tube has a distal portion. The assembly further comprises a coupling, which joins the distal region of the sheath and the distal portion of the catheter tube. The coupling causes bending of the catheter tube outwardly through the opening, in response to sliding movement of the catheter tube within the interior bore toward the distal region of the sheath.

摘要： Systems and methods ablate tissue within the body using a flexible guide element having an axis. A mechanism flexes the element along its axis. The flexible element carries a region for emitting energy. The region creates a lesion having a contour that follows the flexure of the element. The region creates a single continuous lesion that is curvilinear, long and thin. Manipulating such systems and methods creates diverse, specially shaped lesions in body tissue.

摘要： A method of ablating tissue in the heart to treat atrial fibrillation introduces into a selected atrium an energy emitting element. The method exposes the element to a region of the atrial wall and applies ablating energy to the element to thermally destroy tissue. The method forms a convoluted lesion pattern comprising elongated straight lesions and elongated curvilinear lesions. The lesion pattern directs electrical impulses within the atrial myocardium along a path that activates the atrial myocardium while interrupting reentry circuits that, if not interrupted, would cause fibrillation. The method emulates the surgical maze procedure, but lends itself to catheter-based procedures that do not require open heart surgical techniques. A composite structure for performing the method is formed using a template that displays in planar view a desired lesion pattern for the tissue. An array of spaced apart element is laid on the template. Guided by the template, energy emitting and non-energy emitting zones are formed on the elements. By overlaying the elements, the composite structure is formed, which can be introduced into the body to ablate tissue using catheter-based, vascular access techniques.
