Abstract
A device for accessing tissue within a body lumen comprises an elongated body portion defining a lumen and an anchoring mechanism including an expanding structure on a distal portion of the elongated body portion. The anchoring mechanism moves the expanding structure from an insertion configuration in which the expanding structure is constricted against the device to an operative configuration in a body in which the expanding structure expands away from the device without altering a length of the anchoring mechanism in combination with a control mechanism for selectively engaging the anchoring mechanism.
Claims20
A tissue access device comprising:
- an endoscope having a lumen therethrough;
- and
- an anchoring member coupled to and extending from an opening on a lateral side of a distal portion of the endoscope, the anchoring member configured to deliver to a body lumen a suction force applied at a proximal end of the device, the suction force configured to cause the anchoring member to engage tissue defining the body lumen.
A tissue access device comprising:
- an endoscope having a lumen therethrough;
- and
- an anchoring member configured to apply an adhesive force to body tissue, the anchoring member having a first end coupled to an opening in a sidewall of a distal portion of the endoscope and a second end configured to contact the body tissue during application of the adhesive force,
- wherein the second end has a diameter greater than a diameter of the first end.
A method of accessing target tissue within a body lumen comprising:
- inserting a medical device at a location proximal the target tissue, wherein the medical device comprises an endoscope having a lumen therethrough, and an anchoring member coupled at a first end to an opening in a lateral side of a distal portion of the endoscope,
- inserting a tubular guiding component through the lumen and out of the opening to engage a portion of the target tissue;
- applying suction through the lumen to the anchoring member to cause a second end of the anchoring member to engage a surface of the target tissue,
- wherein a diameter of the second end of the anchoring member is greater than a diameter of the first end of the anchoring member.
