Abstract

In one aspect, the present disclosure relates to a device for obtaining biological tissue. In some embodiments, the device can include a first row of a plurality of hollow tubes; a second row of a plurality of hollow tubes, adjacent the first row of hollow tubes; a third row of a plurality of hollow tubes, adjacent the second row of hollow tubes, the first, second and third rows forming an array of hollow tubes; wherein each hollow tube can include at least one point at the distal end of the hollow tube, the plurality of rows forming a two dimensional array of hollow tubes; wherein an inner diameter of the at least one tube is less than about 1 mm, the distal end of each of the hollow tubes is configured to be inserted into a biological tissue donor site to remove a portion of tissue therefrom when each of the hollow tubes is withdrawn from the donor site.

Claims

1. A device for obtaining biological tissue comprising;

an array of hollow tubes, the array comprising

a first row of a plurality of hollow tubes;

a second row of a plurality of hollow tubes, adjacent the first row of hollow tubes;

a third row of a plurality of hollow tubes, adjacent the second row of hollow tubes, the first, second and third rows forming an array of hollow tubes;

wherein each hollow tube comprises two points at the distal end of the hollow tube, the plurality of rows forming a two dimensional array of hollow tubes;

wherein the two points are formed by a first bevel on a first external side of an outer surface of the hollow tube and a second bevel on a second external side of an outer surface of the tube opposing the first side of the hollow tube;

the first bevel having at least two angle sections including a first shallow angle section to form a first narrow heel and the second bevel having at least two angle sections including a second shallow angle section to form a second narrow heel;

the array comprising a circle having an area of about one square inch;

wherein an inner diameter of each hollow tube is less than about 1 mm, the distal end of each of the hollow tubes is configured to be inserted into a biological tissue donor site to remove a portion of tissue therefrom when each of the hollow tubes is withdrawn from the donor site;

wherein the array comprises a sufficient number of hollow tubes to withdraw about 0.1 square inches of tissue from the donor site with a single insertion of the array;

a first solenoid, wherein first the solenoid actuates at least a first row of hollow tubes to insert at least the first row of hollow tubes into the biological tissue donor site.

2. The device of claim 1, wherein the donor site comprises an area of about one square inch.

3. The device of claim 1 wherein the array of hollow tubes comprises about 300 hollow tubes.

4. The device of claim 1 comprising:

a plurality of pins, each of the pins provided within a central lumen of each of the hollow tubes.

5. The device of claim 1, comprising a stop to limit the depth of insertion into biological tissue of each of the hollow tubes in the array of hollow tubes.

6. The device of claim 1, comprising a second solenoid, wherein the second solenoid actuates in a direction opposite the first solenoid.

7. The device of claim 1, comprising a force sensor, wherein the force sensor senses the force with which the device is applied to the biological tissue donor site.

8. The device of claim 1, wherein the first narrow heel comprises less than about 10% of the inner diameter of the hollow tube and the second narrow heel comprises less than about 10% of the inner diameter of the hollow tube.

9. The device of claim 1, wherein the hollow tube has an inner diameter of less than about 0.8 mm.

10. The device of claim 1, wherein the biological tissue comprises skin tissue and adipose tissue.
