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, the elastic element of the control portion defining a plurality of lumens extending between a proximal end portion and a distal end portion of the elastic element, each lumen of the plurality of lumens configured to receive a pull wire; and
a plurality of pull wires, each pull wire of the plurality of pull wires corresponding to a respective lumen of the plurality of lumens of the elastic element, each pull wire having an outer diameter less than an inner diameter of its respective lumen.

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.

15. 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, the elastic element defining a plurality of pull wire lumens extending between a proximal end portion and a distal end portion of the elastic element, each pull wire lumen of the plurality of pull wire lumens configured to receive a pull wire; and a plurality of pull wires, each pull wire of the plurality of pull wires corresponding to a respective pull wire lumen of the plurality of pull wire lumens of the elastic element, each pull wire having an outer diameter less than an inner diameter of its respective pull wire lumen. - View Dependent Claims (16, 17, 18)
