Abstract
Systems, methods, and apparatuses for assisting with submucosal dissections include a retraction strip body. The retraction strip body is formed at least partially from a deformable material. The retraction strip body is capable of being selectively moved between a first condition and a second condition. In the first condition, the retraction strip body is capable of engaging a target patient tissue. In the second condition, the retraction strip body is capable of retracting the target patient tissue. At least one tissue engagement member is located on the retraction strip body.
Claims15
A system for assisting with submucosal dissections, comprising:
- a tissue retraction device having
- a retraction strip body, the retraction strip body having first and second ends spaced laterally apart, the retraction strip body being formed at least partially from a deformable material, the retraction strip body being capable of being selectively moved between a first condition, in which the retraction strip body defines a first radius of curvature between the first and second ends, and a second condition in which the retraction strip body defines a second radius of curvature between the first and second ends, such that in the first condition, the retraction strip body is capable of engaging a target patient tissue, while in the second condition, the retraction strip body is capable of exerting a tensile force on the target patient tissue to retract the target patient tissue, and
- at least two sets of tissue engagement members, a first set of tissue engagement members being located on the retraction strip body first end, a second set of tissue engagement members being located on the retraction strip body second end, the tissue engagement members being at least one of a barb, a clip, a hook, or an adhesive;
- an endoscope, the endoscope having a proximal end and a distal end, the endoscope having an endoscope lumen extending longitudinally between the endoscope proximal end and the endoscope distal end;
- and
- a dissector;
- wherein the deformable material is a malleable material, and the retraction strip body at least partially formed from a malleable material is capable of being selectively deformed to, and retained in, at least a selected one of the first and second conditions.

- a tissue retraction device having
- a retraction strip body, the retraction strip body having first and second ends spaced laterally apart, the retraction strip body being formed at least partially from a deformable material, the retraction strip body being capable of being selectively moved between a first condition , in which the retraction strip body defines a first radius of curvature between the first and second ends, and a second condition in which the retraction strip body defines a second radius of curvature between the first and second ends, such that in the first condition, the retraction strip body is capable of engaging a target patient tissue, while in the second condition, the retraction strip body is capable of capable of exerting a tensile force on the target patient tissue to retract the target patient tissue, and
- at least two sets of tissue engagement members, a first set of tissue engagement members being located on the retraction strip body first end, a second set of tissue engagement members being located on the retraction strip body second end, the tissue engagement members being at least one of a barb, a clip, a hook, or an adhesive;
- an endoscope, the endoscope having a proximal end and a distal end, the endoscope having an endoscope lumen extending longitudinally between the endoscope proximal end and the endoscope distal end;
- and
- a dissector;
- wherein the deformable material is a flexible stainless steel bistable spring band, the retraction strip body in the first condition is shaped to engage the outer surface of a mandrel, each tissue engagement member is in a flattened condition when the retraction strip body is in the first condition, and each tissue engagement member is in a flared condition when the retraction strip body is at least partially in the second condition.
