A needle-like structure includes projections formed in rows on a substrate and extended in a direction, and needle portions formed on each of the projections such that the needle portions are spaced part from one another.

By rotationally casting soft robots, no bonding of different material layers is required. Soft robots including one or more integrated enclosed compartments are constructed from fibers that are embedded directly into the mold prior to adding elastomeric precursors.

Simulated tissue structures for practicing surgical techniques and methods of manufacturing those structures are provided. In particular, a realistic organ model or simulated tissue portion for practicing the removal of a tumor or other undesired tissue followed by suturing a remnant defect as part of the same surgical procedure is provided. The simulated tissue structures include a polyp simulation having a suturable mesh layer that is separable from a defect layer. A simulated colon model with interchangeable and suturable tissue pods is also provided as is a fully suturable rectum model and a rectum model with integrative suturable and removable polyp zones.

The method comprises of placing the palm side of a glove mold facing up, and raising the fingers portion of glove mold up, in such a way that the glove mold is tilting up at 15-45 in relative to horizontal position. The first pouring process is carried out by pouring silica gel liquid on the fingers portion of glove mold. Then adjust the glove mold to horizontal position, and rotate the glove mold by using its length as axis. Continue pouring silica gel liquid on the glove mold surface to carry out second pouring process. Let the silica gel liquid to be coated on the whole glove mold surface forming a semi-finished glove. Upon completion, let the glove mold to go through a dripping procedure for dripping treatment. After the dripping treatment, carry out vulcanization and cooling to obtain the corresponding silica gel glove.

The disclosure describes a breast implant device product that mimics the natural pectoral fat of the breast and is characterized by an incomplete pyramid with isosceles triangular base and wedge-shaped edges and sloping faces that meet at acute angles with variable degree located medially, laterally, and on the top and a footprint characterized by a semicircular lower portion and an oval paraboloid upper portion and a center of gravity located closer to the footprint than to the profile, the said footprint is advantageously converging and moving towards the underlying surface as the chest wall with a method of manufacturing and a method of use of the said implant including a breast pyramid sizing system.

A method for providing high-speed three dimensional (3D) printing is provided. The method includes producing at least one three dimensional (3D) printed part. Producing the 3D part includes continuously constructing to extend outwardly a diameter of a rotating cylindrical core via continuous deposition of a layer, and defining a first pattern in the continuously deposited layer corresponding to a cross-section of the at least one 3D printed part.

A method for production of a tubular body applying the following steps: Pressureless application of at least one first curable plastic layer made of reactive polyurethane materials with a core via a rotational molding process, Curing the at least one plastic layer, Winding at least one reinforcement layer onto the at least one first plastic layer, Pressureless application of at least one second curable plastic layer, wherein the reinforcement layer is embedded without holes between the two plastic layers, and Removal of the core after completion of the body. Because of this, the position of the reinforcement layer 7 can be individually established and it can be ensured that the reinforcement layer will not penetrate into the first plastic layer during winding after the curing of the first plastic layer.

Described herein are apparatuses and methods of creating fibers, such as microfibers and nanofibers for the production of clothing items and footwear. Also described herein is a microfiber and/or nanofiber coating system having a support that holds an object to be coated by fibers during the coating process. The support may move the object with respect to the fibers, such that at least a portion of each of the exterior surfaces of the object are coated by the fibers formed by the microfiber and/or nanofiber coating system.

Apparatus for producing a three dimensional nanofiber structure includes (1) at least two spaced electrodes; (2) a spinner adapted to rotate the at least two spaced electrodes; (3) a syringe assembly adapted to eject a polymer solution from a syringe of the syringe assembly towards the at least two spaced electrodes while the at least two spaced electrodes are rotated by the spinner; and (4) a power supply assembly for providing the two spaced electrodes at a first electric potential, and for providing the syringe at a second electric potential which is different from the first electric potential. A composition of matter may include (1) a least one layer of nanofibers in which a distribution of angles of fibers is aligned; and (2) at least one gel layer, wherein the at least one layer of microfibers and the at least one gel layer alternate to form a laminate.
