DEPLOYMENT CONTROL APPARATUS FOR A CATHETER WITH A DEPLOYABLE ARRAY

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.
