Abstract
A medical device may include a housing. The housing may include an outer wall, an inner wall spaced from the outer wall, and a cavity defined by the outer wall and the inner wall. The distal end of the outer wall may be disposed proximally from the distal end of the inner wall. The housing may further define a passageway therethrough. The cavity may be in fluid communication with a port configured to adjust pressure within the cavity.
Claims20
A medical device, comprising:
- a housing including an outer wall, an inner wall spaced from the outer wall, and a cavity defined by the outer wall and the inner wall, wherein the distal end of the outer wall is disposed proximally from the distal end of the inner wall, the housing further defines a passageway therethrough, and the cavity is in fluid communication with a port configured to adjust pressure within the cavity.
The medical device of claim 8, wherein the housing defines an opening having a plurality of straight edges.
An endoscopic mucosal resection device, comprising:
- an elongate member including a proximal end, a distal end, and a lumen extending therebetween;
- a housing operably coupled and movable relative to the distal end of the elongate member, the housing including an outer wall, an inner wall spaced from the outer wall, and a cavity defined by the outer wall and the inner wall, wherein the distal end of the outer wall is disposed proximally from the distal end of the inner wall, the housing further defines a passageway therethrough, and a proximal portion of the passageway is configured to receive the elongate member therein;
- and
- a cutting device.
A method of resecting tissue from within a patient, comprising:
- advancing an endoscopic mucosal resection device to a target location within the patient, the endoscopic mucosal resection device comprising:
- a housing operably coupled and movable relative to the distal end of an elongate member, the housing including an outer wall, an inner wall spaced from the outer wall, and a cavity defined by the outer wall and the inner wall, wherein the housing further defines a passageway therethrough, a proximal portion of the passageway being configured to receive the elongate member therein;
- disposing a distal end of the housing adjacent a tissue wall;
- applying suction to the cavity to draw at least one layer of the tissue wall into the cavity;
- and
- resecting a portion of tissue drawn into the cavity.
