Magnetic compression anastomosis device
An apparatus for joining organ wall portions of first and second hollow organs, including first and second connectors, wherein the first and second connectors are magnetically attracted to one another. A device for delivering and deploying the first and second connectors to portions of the first and second hollow organs can be provided, wherein the device is configured and dimensioned to axially align the first and second connectors for performing circular anastomosis of the first and second hollow organs.
1. An apparatus for joining organ walls of first and second hollow organs, comprising:
a first connector;
a second connector defining a cavity, the first and second connectors magnetically attracted to one another; and
a device for delivering and deploying the first and second connectors to the first and second hollow organs, the device including a first portion and a second portion, the second portion sized to pass through the first and second connectors, the first portion releasably housing the second connector at a distal end thereof and the second portion releasably affixed to the first connector, the second portion including a cutting edge facing the first portion and configured to pass through the cavity of the second connector, wherein the first portion includes an actuator that is releasably engageable with the second portion and is moveable between a first position in which disengagement of the second portion from the actuator is allowed and a second position in which disengagement of the second portion from the actuator is prevented.
2. The apparatus of claim 1 , wherein at least one of the first and second connectors produces a magnetic field.
3. The apparatus of claim 1 , wherein each of the first and second connectors produces a magnetic field.
4. The apparatus of claim 1 , wherein the cutting edge is configured to core tissue within the cavity.
5. The apparatus of claim 1 , wherein the cutting edge is disposed on an outer dimension of the second portion.
6. The apparatus of claim 5 , wherein the cutting edge is annular.
7. The apparatus of claim 5 , wherein the cutting edge defines a diameter less than a diameter defined by the cavity.
8. The apparatus of claim 1 , wherein the second portion includes a proximally extending rod received by the first portion.
9. The apparatus of claim 1 , wherein the second portion includes a rod, the rod of the second portion being releasably engagable with the actuator.
10. The apparatus of claim 1 , wherein the second portion includes a rod, the rod of the second portion being slidably engagable with the actuator such that as the device is actuated, the rod approximates the first and second portions together to bring the first and second connectors into close approximation with one another, wherein the magnetic attraction between the first and second connectors applies a compressive force to tissue captured therebetween.
11. The apparatus of claim 1 , wherein the first and second connectors define annular bodies.
12. The apparatus of claim 1 , wherein at least one of the first and second connectors includes a protrusion on a surface facing the other one of the first and second connectors.
13. The apparatus of claim 1 , wherein at least one of the first and second connectors includes an inner connector member and an outer connector member.
