Abstract

The present invention provides a cell transplantation device which is capable of inserting cells for transplantation into a cell-deficient site without application of direct external force to the cells. The present invention discloses a cell transplantation device provided with a plate-type carrier with at least one pass-through hole formed on its side surface, a linear member to be threaded through the pass-through hole, and a pusher member which engages with the linear member that comes out from each exit of the pass-through holes.

Claims (13)

1. A cell transplantation device comprising:

a plate-type carrier which has at least one pass-through hole formed on its side surface,

a linear member to be threaded through the pass-through hole, and

a pusher member which engages with the linear member when the linear member comes out from each exit of the pass-through hole; wherein the pusher member comprises arms that directly engage with the linear member and a pusher member body that supports the arms, said arms having a length so as to form a predetermined space between the carrier and the pusher member body when the arms are engaged with the linear member.

2. The cell transplantation device according to claim 1 , wherein the predetermined space is greater in height than a cell for transplantation to be mounted on the carrier.

3. The cell transplantation device according to claim 1 , wherein the end of the arm is V-shaped.

4. The cell transplantation device according to claim 1 , wherein the end of the arm has a hole through which the linear member can pass.

5. The cell transplantation device according to claim 1 , wherein the pusher member comprises a stopper that makes contact with a surface around a cell-deficient site when a cell for transplantation is inserted into the cell-deficient site at the optimum position.

6. The cell transplantation device according to claim 1 , wherein the carrier has two pass-through holes formed therein.

7. The cell transplantation device according to claim 6 , wherein positions of the pass-through holes formed differ in the level of the thickness of the carrier so that they do not cross with each other.

8. The cell transplantation device according to claim 1 , wherein the carrier is disk-shaped and the pass-through holes run through the center of said carrier.

9. The cell transplantation device according to claim 6 , wherein each exit of the pass-through holes is distributed at intervals of 90° circumferentially in the carrier.

10. The cell transplantation device according to any claim 1 , wherein the carrier is made of a biodegradable material or bioabsorbable material.
