Follicular transplantation device and method
First Claim
1. A method for removing a hair follicle from an animal comprising:
- sliding a first tubular member over a single hair of the animal until the first tubular member reaches an upper end of a follicle of the hair;
sliding a second tubular member over the first tubular member and into a dermis of the animal surrounding the hair follicle to a position deeper into the dermis than the upper end of the follicle; and
withdrawing the second tubular member with the hair follicle from the dermis.

Abstract
A hair transplantation device can include a generally tubular guide configured to locate a hair follicle bulb by sliding over a hair shaft down to an upper surface of a hair follicle. The guide can have a blunt distal end configured not to transect the hair follicle bulb. The hair transplantation device also includes an outer tubular member sized and configured to be advanced around the guide. The outer tubular member has a dilator and a harvester. The device can be used in a follicle transplantation method in which the guide locates a hair follicle bulb, and the outer tubular member is slid over the guide. Once the outer tubular member is aligned with the guide, the harvesting portion is advanced, cutting dermal tissue surrounding the hair follicle. The outer tubular member is then withdrawn with the hair follicle, relocated in a recipient area, and the hair follicle implanted.

6. A method for transplanting a hair follicle from an animal comprising:
-
sliding a first tubular member over a single hair of the animal located at a first location on the animal until the first tubular member reaches an upper end of a follicle of the hair;
sliding a second outer tubular member over the first tubular member and into the dermis of the animal surrounding the hair follicle to a position beyond the upper end of the follicle;
withdrawing the second tubular member with the hair follicle from the dermis;
implanting the hair follicle into a second location on the animal. - View Dependent Claims (7, 8, 9, 10, 11)

12. A medical device comprising:
-
A first tubular member having a blunt distal end; and
A second tubular member having a distal end configured to spread dermal tissue of an animal and cut dermal tissue around a hair follicle of the animal and wherein the second tubular member is configured to be slidably applied around the first tubular member. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A medical device comprising:
-
a guide configured to locate a hair follicle bulb in dermal tissue of an animal; and
a first tubular member configured to be slidably engaged around the guide;
wherein the first tubular member comprises a dilator and a harvester, and wherein the harvester is slidably advanceable with respect to the guide such that the harvester can cut the dermal tissue surrounding the hair follicle bulb. - View Dependent Claims (28, 29)
