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. A surgical device comprising:
a first portion defining a cavity;
a first connector releasably housed in the cavity;
a second connector, the first and second connectors magnetically attracted to one another; and
a second portion releasably affixed to the second connector, the second portion being dimensioned to pass through the first and second connectors and including a cutting edge facing the first portion, the cutting edge configured to pass through the cavity of the first portion,
wherein the first portion includes an actuator releasably engagable with the second portion, the actuator movable between a first position in which the actuator is positioned to allow disengagement of the second portion from the actuator and a second position in which the actuator is positioned to prevent disengagement of the second portion from the actuator.
2. The device according to claim 1 , wherein at least one of the first or second connectors produces a magnetic field.
3. The device according to claim 1 , wherein each of the first and second connectors produces a magnetic field.
4. The device according to claim 1 , wherein the cutting edge is configured to core tissue within the cavity.
5. The device according to claim 4 , wherein the cutting edge is annular.
6. The device according to claim 1 , wherein the cutting edge is disposed on an outer dimension of the second portion.
7. The device according to claim 1 , wherein the cutting edge defines a diameter less than a diameter defined by the cavity.
8. The device according to claim 1 , wherein the second portion includes a proximally extending rod, the proximally extending rod received by the first portion.
9. The device according to claim 8 , wherein the rod of the second portion is releasably engaged with the actuator.
10. The device according to claim 9 , wherein the rod is slidably engaged with the actuator such that as the actuator is actuated, the rod approximates the first and second portions to approximate the first and second connectors, wherein the magnetic attraction between the first and second connectors applies a compressive force to tissue captured between the first and second connectors.
11. The device according to claim 1 , wherein the first and second connectors define annular bodies.
12. The device according to claim 1 , wherein at least one of the first or second connectors includes a protrusion on a surface facing the other one of the first or second connectors.
13. The device according to claim 1 , wherein at least one of the first or second connectors includes an inner connector member and an outer connector member.
14. A surgical device comprising:
a handle;
an elongated body extending from the handle;
a first portion disposed on a distal portion of the elongate body, the first portion defining a cavity;
a first connector releasably housed in the cavity;
a second connector, the first and second connectors magnetically attracted to one another; and
a second portion releasably affixed to the second connector, the second portion being dimensioned to pass through the first and second connectors and including a cutting edge facing the first portion, the cutting edge configured to pass through the cavity of the first portion,
wherein the first portion includes an actuator releasably engagable with the second portion, the actuator movable between a first position in which the actuator is positioned to allow disengagement of the second portion from the actuator and a second position in which the actuator is positioned to prevent disengagement of the second portion from the actuator.
15. A surgical device comprising:
a first portion defining a cavity;
a first connector releasably housed in the cavity;
a second connector having an innermost wall defining a central opening; and
a second portion dimensioned to pass through the central opening of the second connector and through the first connector, the innermost wall of the second connector releasably affixed to the second portion, the second portion including a cutting edge facing the first portion configured to pass through the cavity of the first portion.
16. The surgical device according to claim 15 , wherein the first and second connectors are magnetically attracted to one another.
17. The surgical device according to claim 15 , wherein the first portion includes an actuator releasably engagable with the second portion, the actuator movable between a first position in which the actuator is positioned to allow disengagement of the second portion from the actuator and a second position in which the actuator is positioned to prevent disengagement of the second portion from the actuator.
18. The surgical device according to claim 15 , wherein the second portion includes an outermost wall, the second connector releasably affixed to the outermost wall of the second portion.
