The tensioning device comprises at least one body surface grabber capable of engaging the body surface, and the tensioning device is configured to be able to create tension on a body or skin surface by simply displacing the tensioning device as a whole in one general direction. The tensioning device may be secured, for example, to a patient chair. ## Claims ### Claim 1 A tensioning device for applying tension to a skin surface during a medical procedure, comprising: a displacement mechanism; a securing member; a frame comprising at least one anchoring location for receiving the displacement mechanism, a heel and two arms, wherein the heel and each of the two arms having a skin contact surface; at least one of the skin contact surfaces comprising at least one body surface grabber, wherein the at least one body surface grabber is configured to engage the skin surface; and the frame further comprising an anchoring location for receiving the securing member, wherein the securing member is configured to secure the frame to the skin surface; wherein, the frame is configured to be moved by the displacement mechanism in substantially one direction along the skin surface such that to cause tension in a treatment area on the skin surface while the medical procedure is being performed. ### Claim 2 (depends on 1) The device of claim 1, wherein the displacement mechanism comprises a first portion configured to be attached to the at least one anchoring location and a second portion configured to be attached at a location somewhere other than on the tensioning device. ### Claim 3 (depends on 1) The device of claim 1, wherein the displacement mechanism is removably or permanently attached to the frame of the tensioning device. ### Claim 4 (depends on 2) The device of claim 2, wherein a first portion of the displacement mechanism is attached to the frame of the tensioning device and a second portion of the displacement mechanism is attached to a patient chair. ### Claim 5 (depends on 1) The device of claim 1, wherein the at least one body surface grabber is disposed on the skin contact surface of the heel. ### Claim 6 (depends on 1) The device of claim 1, wherein the securing member is configured to retain a material to capture fluids from the procedure. ### Claim 7 (depends on 1) The device of the claim 1, wherein the securing member is configured to provide supplemental tension. ### Claim 8 (depends on 1) The device of claim 1, wherein the treatment area is disposed between the displacement mechanism and the securing member. ### Claim 9 (depends on 1) The device of claim 1, wherein the at least one body surface grabber comprises one or more of a barb or a microbarb. ### Claim 10 (depends on 1) The device of claim 1, wherein the displacement mechanism comprises a strand. ### Claim 11 (depends on 1) The device of claim 1, wherein the device is configured and sized to tension the body surface containing hair follicles such that the hair follicles can be harvested from or implanted into the tensioned skin surface. ### Claim 12 (depends on 1) The device of claim 1, wherein the at least one body surface grabber comprises adhesive or suction. ### Claim 13 (depends on 1) The device of claim 1, wherein each of the anchoring locations comprises a groove. ### Claim 14 (depends on 1) The device of claim 1, wherein the displacement mechanism comprises a magnetic element such that movement of the tensioning device is enabled by activation of a magnetic field. ### Claim 15 (depends on 1) The device of claim 1, wherein the displacement mechanism comprises an inelastic strand of substantially fixed length, and the frame further comprising a tensioning mechanism configured to provide variable tension. ### Claim 16 (depends on 1) The device of claim 1, wherein the displacement mechanism has a closed loop configuration. ### Claim 17 (depends on 1) The device of claim 1, further comprising a tension indicator to indicate the amount of skin tension. ### Claim 18 (depends on 1) The device of claim 1, wherein the frame is configured to conform to the skin surface. ### Claim 19 (depends on 1) The device of claim 1, the frame further comprises a fluid flow channel configured to provide fluid to a treatment area.
