TISSUE RESECTION SNARES |
摘要 |
A tissue resection device for resecting tissue from a target site within a patient's body. The device includes an elongate shaft having a proximal end and a distal end. An actuation member extends partially through the shaft, and reciprocates within the shaft between a retracted position and an extended position. Multiple snare wires extend through the actuation member, and emerge outwards from a distal portion of the actuation member. The snare wires cooperate and join to form a snare loop, which engages the tissue intended to be resected. The snare loop is configured to enhance friction while engaging the tissue, to resect the tissue. |

1. A tissue resection device comprising:
an elongate shaft having a proximal end and a distal end; an actuation member extending at least partially through the elongate shaft, and being configured to reciprocate within the shaft between a retracted position and an extended position; one or more snare wires extending through a lumen of the actuation member and emerging outwards from a distal portion of the actuation member; and a snare loop formed by the one or more snare wires, the snare loop being configured to engage tissue intended to be resected from a target site, and further comprising a plurality of elements positioned over a peripheral surface of the snare loop, the elements being configured to increase friction between the tissue and the snare loop. |
