Abstract
A system for endoscopically forming an anastomosis between two naturally adjacent points in the digestive tract. The system utilizes elongate magnetic devices that, when connected across a tissue boundary, necrose tissue until an anastomosis forms and the devices are passed naturally. Despite the elongate shape of the devices, the resulting anastomosis is substantially round. As such, round anastomoses can be formed having increased diameters merely by increasing the lengths of the devices, obviating the need for wider endoscopes.
Claims9
A system for forming a substantially round anastomosis between two adjacent walls of a digestive tract, the system comprising:
- a first elongated component comprising a first plurality of magnet elements provided in series, the first magnetic implant being flexible and sized for insertion into a working channel of an endoscope;
- and
- a second elongated component comprising a second plurality of magnet elements provided in series, the second elongated component being magnetically attracted to the first elongated component;
- wherein the magnet elements of at least one of the first and second plurality of magnet elements have a width ranging from about 1.5 mm to about 3.7 mm;
- wherein the first and second elongated components are configured to be deployed into the digestive tract in a delivery configuration;
- wherein the first and second elongated components are further configured to magnetically couple to each other through the two adjacent walls of the digestive tract in a magnetic compression configuration to exert a compression force onto a portion of the two adjacent walls located between the first and second elongated components, the compression force being sufficient to cause ischemic pressure necrosis to subsequently form the substantially round anastomosis;
- and
- wherein the first and second elongated components are further configured to remain magnetically coupled to each other in an excretion configuration to be excreted from the digestive tract.
