Controlling movement of distal portion of medical device
First Claim
1. A medical device, comprising:
- an elongated member including a distal end portion and a proximal end portion, the distal end portion including a deflectable region;
a control portion including an elastic elongated member defining a plurality of lumens extending between a proximal end portion and a distal end portion of the elastic elongated member, wherein the control portion is configured to transition between (i) an elastically deformed configuration, wherein the control portion elastically deforms in response to an applied force, and (ii) a neutral, undeformed configuration, wherein the control portion inherently returns to the neutral, undeformed configuration when the applied force is removed; and
a first locking element disposed on the proximal end portion of the elastic elongated member, the first locking element fixedly attached to a proximal end portion of a pull wire disposed within one of the plurality of lumens;
wherein elastic movement of a first portion of the control portion with respect to a second portion of the control portion is configured to deflect the deflectable region of the elongated member, and wherein removal of the applied force returns the deflectable region to an undeflected state.

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.

9. A medical device, comprising:
-
an elongated member including a distal end portion and a proximal end portion, the distal end portion including a deflectable region; a control portion including an elastic elongated member defining a plurality of lumens extending between a proximal end portion and a distal end portion of the elastic elongated member, wherein the control portion is configured to transition between (i) an elastically deformed configuration, wherein the control portion elastically deforms in response to an applied force, and (ii) a neutral, undeformed configuration, wherein the control portion inherently returns to the neutral, undeformed configuration when the applied force is removed; and an elongate flexible member extending through one of the plurality of lumens; wherein elastic movement of a first portion of the control portion with respect to a second portion of the control portion is configured to deflect the deflectable region of the elongated member, removal of the applied force returns the deflectable region to an undeflected state, and a longitudinal length of the flexible member is substantially constant regardless of a configuration of the control portion. - View Dependent Claims (10, 11, 12, 13, 14, 15)
