A suturing device is made of two hypodermic needles allowing one or more sutures (at the same time) and a retrieval probe to be advanced into a cavity (e.g., a stomach cavity) of the patient. Both the suture and retrieval probes comprise magnets of opposite polarities on their leading ends. Thus, after the suture and retrieval probe are inside the stomach cavity, the suture and retrieval probe may mate and the suture may be transferred from one hypodermic needle to the other using magnetic attraction. In doing so, the suture forms a loop through the stomach. Once removed, this loop, having two ends that are positioned outside the patient's body, can be pulled tight in order to pull the stomach wall closer to the surface of the patient's body. With the stomach wall close to the surface of the patient's body, it is easier to insert a gastrostomy device.
