Abstract
Devices for use with introducers, endoscopes and catheters, where the devices relate to an articulating mechanism that allows a working end of a medical device to be steerable in order to access or visualize targeted sites in the interior of a patient's body.
Claims18
An articulating mechanism for use in a medical device having a handle with a drive unit, the articulating mechanism comprising:
- an elongated sleeve extending from the handle about an axis and having a distal end and a distal slotted articulation portion;
- and
- a tensioning sleeve extending from the handle and having a distal end and an interior channel extending therethrough, the tensioning sleeve having a proximal portion configured to receive a force from the drive unit to cause movement of the proximal portion relative to the handle, the tensioning sleeve located adjacent to the elongated sleeve, where the distal end of the elongated sleeve and the distal end of the tensioning sleeve are coupled at a coupling portion to prevent relative movement of the tensioning sleeve and elongated sleeve at the coupling portion but to allow relative movement of a remaining portion of the tensioning sleeve and elongated sleeve in response to movement of the proximal portion to articulate the distal slotted articulation portion to permit articulation of the elongated sleeve and tensioning sleeve at the coupling portion.
An articulating medical device, comprising:
- a handle;
- a first elongated sleeve with a distal end having a first slotted articulating portion, the first elongated sleeve extending from the handle;
- a second elongated sleeve with a distal end having a second slotted articulating portion, the second elongated extending from the handle, wherein a distal end of the first elongated sleeve is affixed to a distal end of the second elongated sleeve at a coupled portion to prevent relative movement of the first elongated sleeve and second elongated sleeve at the coupled portion;
- and
- an actuation mechanism coupled to the handle, where the actuation mechanism moves the first elongated sleeve and the second elongated sleeve at a proximal region relative to one another to thereby cooperatively articulate distal ends of the first elongated sleeve and second elongated sleeve.
