| 20080234602 | BIOLOGICAL UNIT REMOVAL TOOLS WITH RETENTION MECHANISM - Tools and methods are provided for removing biological units from a body surface utilizing a removal tool. The tools may incorporate retention members and mechanisms configured to impede movement of the biological unit in the direction of a distal end of the tool and to improve retention of the biological unit in the tool. Some of the retention members are stationary and some are movable within the lumen of the biological unit removal tools. The distal tips of the tools are desirably configured to reduce the chance of transection of a biological unit, such as by including both cutting segments and blunt relief segments. A number of dual concentric tube embodiments permit a division of removal functions. Distal fluid or gas delivery may supplement a vacuum in a luminal space to help extract biological units from surrounding tissue. | 09-25-2008 |

| 20090005765 | FOLLICULAR UNIT HARVESTING TOOLS INCLUDING DEVICES AND THEIR USE FOR SEVERING CONNECTIVE TISSUE - Devices and methods are disclosed which provide for harvesting hair follicular units, including severing any remaining connective tissue strands during the harvesting process, so that the harvested follicular units are retained in the harvesting tool without being damaged. The devices and methods of the present invention are especially useful with the partially or substantially automated systems and methods for hair harvesting and transplantation. The follicular unit harvesting tools may comprise a harvesting cannula and a grasping device moveable relative to each other. | 01-01-2009 |
| 20100234871 | SYSTEM AND METHOD FOR HARVESTING AND IMPLANTING HAIR USING IMAGE-GENERATED TOPOLOGICAL SKIN MODELS - Systems and methods are provided for orienting a hair harvesting tool relative to a follicular unit to be harvested. Further, systems and methods of implanting follicular units are provided, which are based on the orientation of the existing follicular units or based on pre-determined insertion angle. The provided systems and methods use image processing and image-generated topological skill models. In some embodiments surface fit is performed using, for example, a planar fit, quadric fit, cubic fit, mesh fit and parametric fit. | 09-16-2010 |
| 20110060321 | FOLLICULAR UNIT HARVESTING TOOL - The invention provides a device and a method for improving hair harvesting and extraction. The device includes a mechanism for assisting in separation of the hair graft from the surrounding connective tissue. The apparatus and methods of the current invention are such that the viability of the follicular unit contained within the extracted plug is substantially preserved. | 03-10-2011 |
