CONTROLLING MOVEMENT OF DISTAL PORTION OF MEDICAL DEVICE
First Claim
1. A medical device capable of omni-directional control, comprising:
- an elongated member including a deflectable portion at a distal end portion of the elongated member; and
a control portion disposed on the elongated member, the control portion including an elastic element and a flexible element, angular movement of a first portion of the control portion with respect to a second portion of the control portion adapted to amplify deflection of the deflectable portion of the elongated member.

Abstract
A medical device allows movement control of a distal end portion of the medical device and is adapted for one-handed operation. The medical device is capable of omni-directional control of the distal end portion of the device. The device has an elongated member including a deflectable portion at a distal end portion of the elongated member. The device also has a control portion disposed on the elongated member. This control portion can be a handle for one-handed use by an operator of the medical device. The control portion comprises an elastic element and a flexible element. Angular movement of a first portion of the control portion with respect to a second portion of the control portion results in amplification of that angular movement in the deflectable portion of the device.

16. A handle mechanism for use with a deflectable medical device, comprising:
a control portion adapted for angular movement and configured to amplify deflection of a deflectable portion of a deflectable medical device in response to angular movement of the control portion, the control portion including an elastic element and a flexible element, the flexible element being received in a lumen defined by the elastic element, the elastic element being compressible, the flexible element being substantially non-compressible. - View Dependent Claims (17, 18, 19)
