Device and method for implantation of hair grafts into the scalp of a patient. In the device, a cross-sectional shape of a rod riding in an implantation needle is configured with respect to the needle to communicate a vacuum in a chamber anterior to the needle forward to an interior of the needle, thereby facilitating loading of the hair graft into the device by direct-to-needle aspiration of the hair graft.

A structure of aligned (e.g., radially and/or polygonally aligned) fibers, and systems and methods for producing and using the same. One or more structures provided may be created using an apparatus that includes one or more first electrodes that define an area and/or partially circumscribe an area. For example, a single first electrode may enclose the area, or a plurality of first electrode(s) may be positioned on at least a portion of the perimeter of the area. A second electrode is positioned within the area. Electrodes with rounded (e.g., convex) surfaces may be arranged in an array, and a fibrous structure created using such electrodes may include an array of wells at positions corresponding to the positions of the electrodes.

Exemplary embodiments of the present disclosure provide method and apparatus for facilitating stretching of a biological tissue by forming a plurality of micro-slits in the tissue. Each micro-slit can be less than about 2 mm or less than about 1.5 mm long, or even less than about 1 mm, such that small gaps that can heal quickly can be formed when the tissue is stretched. The micro-slits can be formed using a plurality of cutting arrangements or an ablative laser. The micro-slits can be formed in various patterns, including staggered rows, circular or spiral patterns, or random patterns.

An improved skin substitute is presented comprised of a silicone layer backed up with a woven nylon fabric layer, the silicone layer possessing a regular pattern of slits that permit the porosity of the skin substitute to be adjusted by clinicians by means of applying tension to the skin substitute that differentially opens the slits. A variety of therapeutic substances can be applied to the skin substitute to promote healing, including aloe and other medicinal preparations. A layer of water soluble or water insoluble anti-scar compound is also present, the preferred compound being salinomycin.

Devices and methods for inserting an implant into skin or other tissue of a patient can include an insertion device that can enclose and support a hyaluronic thread as it is injected into a patient's skin or other tissue. The device can include a cover member, a non-tubular support member, and the thread. The cover member can have a proximal portion, a closed distal portion, and an inner cavity extending from the proximal portion toward the closed distal portion. The thread can be positioned along a longitudinal length of support member, between the support member and the cover member. The non-tubular support member can extend within the inner cavity of the cover member. The cover member can be moveable relative to the support member to expose the thread.

A transfer device for living organisms is used for placing an object in a living organism. The transfer device for living organisms includes a tubular needle extending in one direction, and a pushing member located inside the needle. The needle is configured to capture an object therein from an opening at a tip of the needle. The pushing member is configured to be movable relative to the needle from inside the needle toward the opening.

The present invention relates to an integrated device for hair follicle extraction and implanting, comprising a body mechanism and a connecting mechanism, the body mechanism comprising a body supporting frame, a first motor, a transmission frame, a second motor, a clamping component, a transmission mechanism and a pushing needle, the connecting mechanism comprises a connecting head, a fixing head and a cutter head, wherein the first motor of the body mechanism controls the up and down movement of the cutter head through the cooperation of the transmission frame and the transmission mechanism, and the second motor controls the pushing needle by the rotary motion of the clamping unit, simultaneously controls the rotational movement of the cutter head through the transmission mechanism. Compared with the prior art, the invention realizes the integrated operation of hair follicle extracting and implanting, and makes the operation of hair follicle implanting more convenient.

A multi-laminar electrospun nanofiber scaffold for use in repairing a defect in a tissue substrate is provided. The scaffold includes a first layer formed by a first plurality of electrospun polymeric fibers, and a second layer formed by a second plurality of electrospun polymeric fibers. The second layer is combined with the first layer. A first portion of the scaffold includes a higher density of fibers than a second portion of the scaffold, and the first portion has a higher tensile strength than the second portion. The scaffold is configured to degrade via hydrolysis after at least one of a predetermined time or an environmental condition. The scaffold is configured to be applied to the tissue substrate containing the defect, and is sufficiently flexible to facilitate application of the scaffold to uneven surfaces of the tissue substrate, and to enable movement of the scaffold by the tissue substrate.
