Abstract: The disclosure provides a needle-electrode anchor system having a needle and an optional electrode with one or more anchors. The system can provide an electrical cutting current to the needle-electrode to create an opening in a tissue portion. An anchor coupled to the needle-electrode can be pushed through the opening with a pusher and pulled into position to set the anchor on a distal surface of the opening. If the tissue portion is to be approximated to another tissue portion, the system can be relocated to another tissue portion and another opening created with the cutting current with another anchor pushed through the opening and secured on a distal surface. Lines coupled to the anchors can be pulled together, approximating the tissue portions. If the tissue portion is to be retracted, an anchor line can be grasped to retract the tissue portion from an adjacent tissue portion.

Abstract: The present disclosure provides a scope carrier that contains a channel for a scope to be inserted therethrough. The scope can be coupled to the scope carrier so that during insertion of the carrier, the objective lens of the scope is used to guide the scope carrier. When the carrier is properly positioned, the scope can be released from the carrier and continue further through the body passages to the intended tissue or structure. The scope carrier can have a relatively much larger channel as a percentage of the carrier outer diameter than a typical scope. The carrier channel can be at least 50% of the scope carrier outer diameter. The carrier channel allows use of a larger scope to be inserted therethrough than has typically been available. The corresponding larger channel of the larger scope allows instruments to be inserted therethrough that heretofore have been unavailable in such combinations.

Abstract: The present disclosure provides a system and method for removing a tissue that extends from a tissue layer, such as a polyp, lesion, or organ. The disclosure provides a medical loop that can be tightened around the tissue extending from the tissue layer by using a one-way anchor and a flexible member to form a loop, the flexible member having ridges to interface with the anchor and secure the flexible member in a tightened position around the tissue. The ridges interface with the tissue to secure the loop in position on the extending tissue and reduce slippage of the loop off of the tissue after tightening the loop. A snare or other cutting instrument may be used to remove the tissue extending outward from the loop. An endoscopic system may be used to guide the medical loop and the cutting instrument to an appropriate location inside a body passage.

Abstract: The present disclosure provides an improved method and device for approximation and retraction of tissue portions during a medical procedure. The disclosure includes a tissue approximator-retractor elastic device, comprising: an elastic portion having a contracted length and adapted to expand to a different length to exert a contractile force; and at least three coupling rings spaced along the elastic portion for an operator to choose between the rings and couple at least two rings to at least two tissue portions to adjust a contractile force on the two tissue portions. The disclosure also discloses providing the device near the tissue portions; coupling a first coupling ring to a first tissue portion; choosing between the remaining coupling rings to select a second coupling ring; engaging the second coupling ring and elastically pulling the elastic portion to the second tissue portion to attach to the second tissue portion.
