Microwave ablation catheter, handle, and system
First Claim
1. A handle for longitudinal movement of a first tubular member over a second tubular member, the handle comprising:
- a handle body defining a slot;
a nose cone movable over the handle body between an extended position and a retracted position; and
a locking pin disposed within and biased out of the slot of the handle body, the locking pin including a retention plate that retains the locking pin within the slot, the locking pin having a locked position in which the nose cone and the handle body are fixed relative to one another and an unlocked position in which the nose cone is movable over the handle body between the extended position and the retracted position.

Abstract
A handle for longitudinal movement of a first tubular member over a second tubular member includes a handle body, a nose cone, a locking mechanism, and a retraction control. The nose cone has a sleeve and an outer wall that define a control channel therebetween. The nose cone is moveable over the handle body between extended and retracted positions. The locking mechanism has locked and unlocked positions for selectively fixing the nose cone in the extended and retracted positions. A finger of the retraction control is positioned within the control channel of the nose cone. The retraction control has first and second positions relative to the nose cone for transitioning the locking mechanism between the locked and unlocked position and for moving the nose cone between the extended and retracted positions.

12. A handle for longitudinal movement of a first tubular member over a second member, the handle comprising:
-
a housing body defining a proximal portion of a through passage of the handle and a nut recess; and an adjustment nut received within the nut recess which longitudinally fixes the adjustment nut relative to the housing body, the adjustment nut coupled to a catheter hub disposed in the proximal portion of the through passage and being configured to longitudinally fix the second member relative to the housing body. - View Dependent Claims (13, 14, 15, 16, 17, 18)
