Abstract
Embodiments of the invention include an endoscope including multiple lumens for tissue acquisition and removal and related methods of use.
Claims17
An apparatus, comprising:
- a tissue acquisition device;
- a tissue removal device, wherein the tissue removal device includes an elongate member defining a suction lumen and an expandable distal assembly coupled to the elongate member, wherein the expandable distal assembly includes an expandable closed end that defines a distal-most end of the tissue removal device and is configured to expand in a body lumen, the expandable distal assembly at least partially surrounding and at least partially containing a distal end of the elongate member in both a collapsed form of the expandable distal assembly and an expanded form of the expandable distal assembly, the suction lumen being configured to collect tissue from the expandable distal assembly;
- and
- an introducing member including a plurality of lumens;
- wherein the tissue acquisition device is disposed within a first lumen of the plurality of lumens, and the tissue removal device is disposed within a second lumen of the plurality of lumens.

An apparatus, comprising:
- an introducing member that includes at least a first lumen and a second lumen;
- a tissue acquisition device disposed within the first lumen, the tissue acquisition device including a first elongate member and a first distal assembly;
- and
- a tissue removal device disposed within the second lumen, wherein the tissue removal device includes a second elongate member defining a suction lumen and an expandable distal assembly coupled to the second elongate member, wherein the expandable distal assembly includes an expandable closed distal end that defines a distal-most end of the tissue removal device and is configured to expand in a body lumen to at least partially surround and at least partially contain a distal end of the second elongate member and the first distal assembly of the tissue acquisition device.

An apparatus, comprising:
- an introducing member including a plurality of lumens;
- a tissue acquisition device;
- and
- a tissue removal device, wherein the tissue removal device includes an elongate member defining a suction lumen, an expandable distal assembly coupled to the elongate member, and a collapsible member having a proximal end fixedly attached to the elongate member and a distal end coupled to the expandable distal assembly, wherein the expandable distal assembly includes a closed distal end that defines a distal-most end of the tissue removal device, the expandable distal assembly being configured to expand with the collapsible member in a body lumen to at least partially surround and at least partially contain both a distal end of the tissue removal device and a distal end of the tissue acquisition device.
