A catheter device (3) configured to provide access to a hollow organ is provided. It includes a body (4) extending longitudinally from a proximal end to a distal end and a flexible insertion tube (8) extending longitudinally from a proximal end to a distal end, wherein the body comprises: an elongated channel (30) along the longitudinal length of the body extending from the proximal end of the body to the distal end of the body, wherein the channel is configured to receive an elongate needle. The body further comprises one or more cutting edges (9, 10) extending rearwardly from a distal end of the body. Furthermore, the flexible insertion tube of the catheter device is coupled to the distal end of the body and comprises a tubular elongated passage (32) aligned with the tubular elongated channel of the body forming a lumen. Kits including such catheter devices and methods for accessing a hollow organ are also provided. |
