Magnetic tissue compression device with backup mechanical latch

A tissue compression device for forming an anastomosis between first and second anatomical structures, the device comprising:

• (a) a first device portion comprising:
• (i) a first magnetic member having a barbed tip, and
• (ii) a first latching member;
• and
• (b) a second device portion comprising:
• (i) a second magnetic member having a bore, and
• (ii) a second latching member,
• wherein the first and second magnetic members are configured to magnetically draw together the first and second device portions in a confronting relationship to compress tissue positioned therebetween,
• wherein the barbed tip of the first magnetic member is configured to pierce through the tissue, wherein the bore of the second magnetic member is configured to receive and retain the barbed tip therein,
• wherein the first and second latching members are configured to lockingly engage one another when the first and second device portions are magnetically drawn together.

A tissue compression device for forming an anastomosis between first and second anatomical structures, the device comprising:

• (a) a first device portion comprising:
• (i) a first magnetic member, and
• (ii) a first latching member;
• and
• (b) a second device portion comprising:
• (i) a socket,
• (ii) a second magnetic member arranged within the socket, and
• (iii) a second latching member,
• wherein the first and second magnetic members are configured to magnetically draw together the first and second device portions in a confronting relationship to compress tissue positioned therebetween,
• wherein the first and second latching members are configured to lockingly engage one another when the first and second device portions are magnetically drawn together,
• wherein the second magnetic member is selectively movable within the socket in a direction away from the first magnetic member to lessen a magnetic attraction force between the first and second magnetic members and thereby facilitate decoupling of the first and second device portions.
