Abstract
A tissue capture device is disclosed. The tissue capture device may include a frame, wherein the frame defines an orifice. The tissue capture device may include a set of fasteners disposed within the orifice, wherein at least some of the fasteners of the set of fasteners are formed from a material displaying one or more shape-changing properties, wherein the one or more shape-changing properties comprises a transition from a deformed phase to a non-deformed phase.
Claims19
A tissue capture device comprising:
- a frame, wherein the frame defines an orifice;
- and
- a set of fasteners disposed within the orifice and encircled by the frame, wherein at least some of the fasteners of the set of fasteners are formed from a material displaying one or more shape-changing properties, wherein the one or more shape-changing properties comprises a transition from a deformed phase to a non-deformed phase, wherein the set of fasteners emerges from a side wall of the frame and extends radially inward from the side wall into the orifice to form an inscribed circle with tips of the set of fasteners.
A capsule endoscopy system, comprising:
- a tissue capture device, the tissue capture device comprising:
- a frame, wherein the frame defines an orifice;
- and
- a set of fasteners disposed within the orifice and encircled by the frame, wherein at least some of the fasteners of the set of fasteners are formed from a material displaying one or more shape-changing properties, wherein the one or more shape-changing properties comprises a transition from a deformed phase to a non-deformed phase, wherein the set of fasteners emerges from a side wall of the frame and extends radially inward from the side wall into the orifice to form an inscribed circle with tips of the set of fasteners;
- and
- a capsule endoscope, wherein the tissue capture device is coupled to the capsule endoscope.
3 more elements
A method, comprising:
- introducing a capsule endoscope to a gastrointestinal (GI) tract, wherein a tissue capture device is coupled to the capsule endoscope, wherein the tissue capture device comprises:
- a frame, wherein the frame defines an orifice;
- and
- a set of fasteners disposed within the orifice and encircled by the frame, wherein at least some of the fasteners of the set of fasteners are formed from a material displaying one or more shape-changing properties wherein the one or more shape-changing properties comprises a transition from a deformed phase to a non-deformed phase, wherein the set of fasteners emerges from a side wall of the frame and extends radially inward from the side wall into the orifice to form an inscribed circle with tips of the set of fasteners;
- reaching an area of interest within the GI tract;
- inserting the set of fasteners of the tissue capture device into tissue of the GI tract in the area of interest, wherein the fasteners are inserted into the tissue in the deformed phase;
- and
- securing the tissue capture device to the tissue of the GI tract by transitioning the set of fasteners of the tissue capture device from the deformed phase to the non-deformed phase.
