In a snare device (10) for capturing an object (22) and/or for cutting a tissue (24) comprising at least one twisted loop of memory shaped material, the loop being housed in and movable relative to a hollow member, especially a catheter (26), to be deployed and retracted into the hollow member (26), a locking wire (18) is provided for being translated through the at least one loop (12) to capture an object (22) between part of the loop (12,14) and the locking wire (18) extending through the loop (12) and/or for puncturing the tissue (24) and/or for cutting the tissue by the loop (12) as combined with the locking wire (18) the locking wire (18) piercing the tissue (24) at an aperture (30) distant from an aperture (28) at least part of the loop (12) extends through the locking wire (18) being translated through the loop (12) and engaging with the same and retracting the loop (12) into the hollow member (26) such that the tissue (24) is cut between both of the apertures (28,30).
