Abstract
Apparatus is provided including a surgical tool configured to be advanced distally within a body of a subject. The surgical tool is shaped to define a side-facing suction port at a distal portion of the surgical tool to facilitate drawing tissue through the suction port and into the surgical tool, and includes a slidable transparent shutter configured to be disposed over the suction port, and to be slidably removed from the suction port. A needle is configured to be slidably disposed within the surgical tool and configured to puncture the tissue while the tissue is in the surgical tool. Other applications are also described.
