A hole forming device for forming a hole in a vessel wall is provided. The hole forming device comprises a shaft. It further comprises a sheath arranged to be axially advanced along the shaft. It yet further comprises a distal end formation on the shaft. The distal end formation is arranged to pierce and pass through a vessel wall and to cooperate with the sheath, so that when the distal end formation has pierced and has been passed through the vessel wall, and the sheath is then advanced along the shaft, a peripheral portion of the vessel wall is drawn into the sheath and severed from the rest of the vessel wall thereby to form a hole in the vessel wall. Advantageously, the device is arranged to form the hole in a hemostatic manner. A method of forming a hole in a vessel wall is also provided. |
