Control mechanism for steerable medical device
First Claim
Patent Images
1. A steering mechanism for use as part of a medical device, comprising:
- a main handle portion including a proximal end and a distal end, the main handle portion extending along a longitudinal axis, the main handle portion configured to be coupled to a medical device;
a rotatable handle portion movably coupled to the main handle portion at an interface, the rotatable handle portion configured to be rotated about the longitudinal axis and relative to the main handle portion, the rotatable handle portion configured to move a distal end of the medical device in a first direction when rotated relative to the main handle portion; and
a control lever axially movable along the longitudinal axis, the control lever configured to move the distal end of the medical device in a second direction different than the first direction, wherein an entirety of the control lever is disposed proximally of the interface.

Abstract
A control mechanism for use with a steerable medical device allows for single-handed operation of at least a distal portion of the medical device. The device can be a catheter or an endoscope, for example.

19. A steering mechanism for use as part of a medical device, comprising:
-
a main handle portion including a proximal end and a distal end, the main handle portion extending along a longitudinal axis, the main handle portion configured to be coupled to a medical device; a rotatable handle portion movably coupled to the main handle portion at an interface, the rotatable handle portion including a proximal end and a distal end, the distal end of the rotatable handle portion disposed adjacent the proximal end of the main handle portion, the rotatable handle portion configured to be rotated about a first axis, the first axis being substantially parallel to the longitudinal axis, the rotatable handle portion configured such that rotation of the rotatable handle portion with respect to the main handle portion causes a distal end of the medical device to move in a first direction; and a control lever movable about a second axis substantially perpendicular to the first axis, an entirety of the control lever being disposed proximally of the interface, wherein the control lever is configured to move the distal end of the medical device in a second direction different from the first direction, the control lever is movable between a first proximal position and a second distal position, and, when in the second distal position, the control lever is positioned closer to the interface than when in the first proximal position. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26)
