Abstract: A deployment control apparatus to control deployment of an array at an end of a catheter includes a pair of walls, a slider assembly, and a deployment shaft. The walls project from a first surface of the interior of a handle. The slider assembly includes a rigid body, an elastomeric element, a tab, and a knob. The elastomeric element is connected to the rigid body and at least partially disposed between the walls to frictionally engage with a surface of each wall. The knob is connected to the rigid body and is configured to maintain the elastomeric element between the walls. The deployment shaft connects the rigid body to the array, wherein a force applied to the knob sufficient to overcome the frictional engagement between the elastomeric element and the surface of each wall causes movement of the slider assembly and the deployment shaft to control deployment of the array.

Abstract: A steering control apparatus includes a first wire and a second wire extending from a distal end of a catheter to a steering assembly. The steering assembly includes a steering knob disposed at an exterior of the handle, a cylindrical steering shaft projecting from the steering knob and into the interior of the handle, a first cylindrical drum disposed within the handle and connected to the first wire, and a second cylindrical drum within the handle and connected to the second wire. The first drum is configured to engage the steering shaft to produce tension on the first wire. The first drum is coaxial with the steering shaft. The second drum is configured to engage the steering shaft to produce tension on the second wire. The second drum is coaxial with the steering shaft and axially adjacent to the first drum.

Abstract: A mapping catheter including an elongate catheter body extending from a proximal end to a distal end, a handle connected to the proximal end of the catheter body, an electrode array connected to the distal end, a deployment shaft, and an irrigation system. The catheter body includes at least one lumen. The irrigation system includes a manifold and a thin, polymeric irrigation tube. The manifold is disposed within the handle and is connectable to a source of irrigation fluid. The irrigation tube is connected to the manifold and extends around the deployment shaft from the manifold to the distal end of the catheter through the catheter body lumen. The irrigation tube forms an annular lumen between an inner surface of the irrigation tube and an outer surface of the deployment shaft. The annular lumen is configured to carry irrigation fluid from the manifold to the array.
