Magnetic compression anastomosis device

An apparatus for joining organ wall portions of first and second hollow organs, comprising:

• first and second connectors, wherein either one or both of the first and second connectors is capable of producing a magnetic field;
• and
• a device for delivering and deploying the first and second connectors to portions of the first and second hollow organs, wherein the device is configured to axially align the first and second connectors for performing circular anastomosis of the first and second hollow organs, the device including:
• a neck portion adapted to releasably house the second connector at a distal end of the neck portion;
• and
• a head portion including a proximal end, wherein the first connector is detachably affixed to the head portion, wherein the second connector includes an inner diametrical surface defining a cavity therethrough, the inner diametrical surface configured to allow the head portion to be retracted through the cavity, the head portion further including:
• a rod extending axially outward from the proximal end of the head portion and configured to be detachably mountable to a distal portion of the neck portion;
• and
• a knife having a cutting edge disposed at the proximal end of the head portion, wherein, after the rod is mounted to the distal portion of the neck portion and the organ wall portions of the first and second hollow organs are pulled into close approximation, as the head portion is retracted into the neck portion, the knife is pulled from a distal-most position to a proximal-most position to core tissue within the first and second hollow organs.

An apparatus for joining organ wall portions of first and second hollow organs, comprising:

• a first connector having a substantially annular ring shape, the first connector including a first inner diametrical surface defining a first cavity therethrough,
• a second connector having a substantially annular ring shape, the second connector including a second inner diametrical surface defining a second cavity therethrough, wherein either one or both of the first and second connectors is capable of producing a magnetic field;
• and
• a device for delivering and deploying the first and second connectors to portions of the first and second hollow organs, the device including:
• a neck portion adapted to releasably house the second connector at a distal end of the neck portion;
• and
• a head portion including an outer diametrical surface and a proximal end, wherein a diameter of the outer diametrical surface is less than a diameter of the second inner diametrical surface, wherein the first connector is detachably affixed to the head portion, the head portion further including:
• an annular knife having a cutting edge disposed at the proximal end of the head portion, wherein, when the head portion is retracted into the neck portion, the annular knife is pulled from a distal-most position to a proximal-most position to core tissue within the first and second hollow organs.
