| 摘要 |
An apparatus or device and a method of using such device for lifting, separating, or removing a first material (e.g., targeted tissue) from a second material (e.g., tissue of a body lumen in a patient) is presented. The method generally comprises placing the distal end of the device to a location that is proximate to the first material; deploying a first anchor member (e.g., T-anchor) fastened to a suture strand into the first material; deploying a second anchor member (e.g., loop anchor) spaced away from the first anchor member, whereas the suture strand is slidably received by the second anchor member; applying tension to the suture strand; cutting the first material at a predetermined depth around the periphery of the first material; and separating or removing the first material along with the first anchor member. The tension applied to the suture strand maintains the first material in a raised position and/or allows the operator to manipulate the first material relative to the second material. |
