Abstract
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.
Claims22
A probe, comprising:
- an outer member defining a distal end and including a wall defining an interior bore;
- an elongate body carried within the outer member interior bore and defining a distal region and a distal end operably connected to the distal end of the outer member;
- and
- a porous inflatable tissue coagulation body that allows substantially no liquid perfusion therethrough when fully inflated supported on the elongate body distal region.
A probe, comprising:
- an elongate body defining a distal region;
- a loop structure associated with the distal end region of the elongate body;
- and
- an inflatable tissue coagulation body that is configured to permit ionic transfer while allowing substantially no liquid perfusion therethrough when fully inflated supported on the loop structure.
