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.

Abstract: An assembly for coupling a drug delivery device to a cartridge is disclosed. Optionally the assembly includes a coupling, for example a cannula, having one end extending toward the cartridge. The cartridge is optionally aligned by a guide. Optionally the cartridge has a limited freedom of movement. The coupling is optionally supported by a mount. In some embodiments, the mount is compliant enough that the end of the coupling that extends toward may move to said limited freedom of movement under a force less than a leak threshold of the connection between the coupler and the cartridge.
