Abstract

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.

Dependent claims

A suturing device comprising:

a first and second hypodermic needle;
one or more sutures comprising a magnetic tip at an end of the one or more sutures and being at least partially disposed in a cavity of the first hypodermic needle;
a magnetic retrieving probe comprising a magnetic tip and being at least partially disposed in a cavity of the second hypodermic needle;
and
a suture advancement component having a cannula, the suture advancement component being at least partially disposed in the cavity of the first hypodermic needle, the one or more sutures being at least partially disposed in the cannula,
wherein the diameter of the magnetic tip of the one or more sutures is greater than an inner diameter of the cannula, and
wherein the magnetic tip of the one or more sutures and the magnetic tip of the magnetic retrieving probe have opposite polarities.
