Abstract
Embodiments of the invention include a medical device for accessing a patient's body portion and used for diagnosis and treatment of medical conditions. Embodiments of the invention may include a particular endoscopic positioning mechanism for placing an endoscope and an additional treatment device within desired body portions in order to assist in diagnosis and treatment of anatomical diseases and disorders. In particular, a medical device according to an embodiment of the invention includes a positioning mechanism configured for movement through at least two degrees of freedom.
Claims31
A medical device, comprising:
- an elongated flexible tube including a distal end and a proximal end, and defining a lumen extending from the proximal end to an aperture at the distal end, wherein the aperture is a side-facing aperture opening laterally along the flexible tube;
- a positioning mechanism positioned at the distal end of the flexible tube proximate the side-facing aperture, the positioning mechanism configured for movement through at least two degrees of freedom to transmit force to a treatment instrument extending through the lumen and to control a direction at which the treatment instrument extends from the side-facing aperture, wherein the positioning mechanism includes a sleeve having a roller positioned on a distal end of the sleeve and being rotatable relative to the sleeve, wherein the sleeve and the roller are configured to move relative to the side-facing aperture to extend external the side-facing aperture, wherein the roller is rotatable relative to the side-facing aperture, the roller including a lumen therethrough configured for receiving the treatment instrument extended distally beyond the lumen;
- an instrument sleeve extending within the lumen of the roller and movable within and distally beyond the lumen of the roller, wherein the instrument sleeve is configured for receiving the treatment instrument and imparting rotation to the treatment instrument upon rotation of the instrument sleeve;
- and
- an actuation wire coupled to a proximal end of the instrument sleeve, wherein longitudinal movement of the actuation member causes longitudinal movement of the instrument sleeve and the treatment instrument.

- a roller positioned at a distal end of a sleeve and rotatable relative to the sleeve, the roller including a lumen therethrough configured for receiving a treatment instrument extended distally beyond the lumen, wherein the sleeve and the roller are configured to move relative to the side-facing aperture to extend external the side-facing aperture;
- an instrument sleeve extending within the lumen of the roller and movable within and distally beyond the lumen in the roller, wherein the instrument sleeve is configured for receiving the treatment instrument and imparting rotation to the treatment instrument upon rotation of the instrument sleeve;
- and
- an actuation wire coupled to a proximal end of the instrument sleeve, wherein longitudinal movement of the actuation member causes longitudinal movement of the instrument sleeve.
