    Abstract: A steerable catheter includes control handle having a generally tubular housing with a longitudinal slot therein in which an axially or longitudinally movable tow-part slideblock resides, and a generally cylindrical, rotatably mounted thumbwheel surrounding a distal portion of the tubular housing, for controlling the axial translation of the slideblock. The pullwire passes into the distal end of the control handle and is only secured to the proximal part of the two-part slideblock so as to prevent the user from placing the pullwire under compression. A tip radius adjusting wire is attached to and extends distally from a slide actuator in the control handle into and through the main catheter shaft portion. The free distal end of the tip radius adjusting wire is selectably locatable at different positions. The radius of curvature of the tip portion, when deflected, depends upon how far distally into the deflectable tip portion the radius adjusting wire has been advanced by the user. The electrode catheter thus has a deflectable tip whose radius of curvature is adjustable over a relatively wide range.

    Abstract: An apparatus for mapping and/or ablating tissue includes a braided conductive member that may be inverted to provide a ring-shaped surface. When a distal tip of the braided conductive member is retracted within the braided conductive member, the lack of protrusion allows the ring-shaped surface to contact a tissue wall such as a cardiac wall. In an undeployed configuration, the braided conductive member is longitudinally extended, and in a deployed configuration, the distal end of the braided conductive member is retracted to invert the braided conductive member.

    Abstract: A handle for use with a catheter, the handle including a housing, a cable, and a guide. The housing has a proximal end, a distal end, and a longitudinal axis that extends from the proximal end of the housing to the distal end of the housing. The cable is disposed in the housing and extends through the proximal end of the housing. A portion of the cable that is disposed in the housing is movable, under compression, in a first direction that is substantially aligned with the longitudinal axis of the housing. The guide is disposed in the housing and is adapted to prevent the portion of the cable from moving in a second direction that is transverse to the first direction when the portion of the cable is moved in the first direction. The handle is suitable for use with an electrophysiology catheter having an elongated shaft.

    Abstract: A device, and method for performing cardiac ablations includes a therapeutic instrument, for example, an ablation catheter (10), to which is mounted a flexible, and braided electrode (14). The electrode configuration is selected so that it has a desired surface area for proper heat convection properties. RF energy (26) is delivered to the electrode to heat, thereby ablate local heart tissue, with the electrode having good convection abilities to protect against coagulation, embolisms, and other undesirable effects of ablation procedures.
