Resin parts and manufacturing method of resin parts
A resin part, wherein the resin part has an asymmetrical shape in a thickness direction, so that a portion in which an increase in internal temperature by heating is relatively quick is positioned closer to one end of the resin part in the thickness direction while a portion in which an increase in internal temperature by heating is relatively slow is positioned closer to the other end of the resin part in the thickness direction, wherein the resin part has an asymmetrical shape in a width direction, so that the portion in which the increase in internal temperature by heating is relatively quick is positioned closer to one end of the resin part in the width direction while a portion in which an increase in internal temperature by heating is relatively slow is positioned closer to the other end of the resin part in the width direction.
Joining element
Disclosed is a joining element, especially a suture material for surgical use. The joining element is composed of a core having a length that extends along a longitudinal direction, the core including a polymer material and an osmotically active substance distributed within the polymer material, wherein the core has a volume capable of swelling along a transverse direction that is perpendicular to the longitudinal direction upon exposure to a fluid; and, a diffusion-controlling extendable membrane that surrounds at least a portion of the length of the core, wherein the membrane is configured to regulate hydration of the core by the fluid, and is further configured to expand along the transverse direction in response to swelling of the core.
Method for producing a molded body
The present invention relates to a method for producing a molded body (10), comprising the following steps: a) providing a molding tool (40) which has at least one receptacle (12) in which at least one material (30) which comprises at least one shape-memory material (31) is introduced, wherein the shape-memory material (31) is present in a first state (111), wherein the material (30) at least partially fills the receptacle (12) of the molding tool (40) in such a manner that said material adjoins at least one surface of the receptacle (12); b) creating a molded body (10) in the receptacle (12) of the molding tool (40) from the material (30), wherein the shape-memory material (31) is present in a second state (112), wherein a form (11) is embossed into the molded body (10) during the second state (112); c) transferring the shape-memory material (31) to a third state (113), wherein the molded body (10) can be deformed during the third state (113) in such a manner that the molded body (10) is demolded from the receptacle (12) of the molding tool (40); and d) at least partially restoring the form (11) of the molded body (10) by transferring the shape-memory material (31) to a fourth state (114), wherein the molded body (10) at least partially resumes the form (11) according to step b) during the fourth state (114).
Joining Element
Disclosed is a joining element (10), especially a suture material for surgical use. The joining element (10) is composed of a first material (12) that is essentially rigid during impingement by a relatively short-lasting tensile load on opposite sides as well as a second material (11) which is connected to the first material. The second material is substantially rigid during impingement by said tensile load on opposite sides while contracting slowly during a second period of time that is longer than the first period of time.
Process for medical components and uses thereof
The invention relates to a process for making a medical component such as a medical implant for example a graft or stent-graft, said medical component comprising ultra high molecular weight polyethylene (UHMWPE) fibers, a medical component obtainable by said process as well as uses of said process and medical component.
Orientated polymeric devices
The present disclosure relates to a shape memory polymer material containing at least one two dimensional region having a first amount of stored stress in a first direction and a second amount of stored stress higher than the first amount of stored stress in a second direction, wherein the two dimensional region is capable of changing shape in only one of the first or second directions.
Joining element
The present disclosure is directed to a joining element having a core having first and second opposed ends that define a length therebetween along a longitudinal direction, a jacket that surrounds the core along at least a portion of the length and defining first and second opposed ends that are spaced along the longitudinal direction, where the first and second opposed ends are in mechanical communication with the first and second ends of the core; and, where one of the jacket and the core is pre-tensioned, and the other of the jacket and the core is configured to transition from a first rigid configuration where its length is constant, to a second deformed configuration where the one of the jacket and the core relaxes from a pre-tensioned state so as to draw the first and second opposed ends of the other of the jacket and the core toward each other.
BIONYLON HAVING TRIPLE SHAPE MEMORY PROPERTIES, AND PREPARATION METHOD THEREFOR
Provided is a method for preparing nylon having triple shape memory effects, comprising the steps of generating amino acid, containing a biomass-derived pyrrolidone group, by using itaconic acid and a diamine; and generating a nylon copolymer by reacting the amino acid containing the pyrrolidone group and an α, ω-aliphatic amino acid. Therefore, provided is a bionylon having triple shape memory effects, capable of shape deformation, fixing and recovery through two steps and adjusting shape recovery temperature to a desired level by controlling the content of a reactant.
Display device and method of manufacturing cover member
A display device includes a display member configured to display an image in a first direction and a cover member on the display member. The cover member includes a flexible member including a front part defining a front plane perpendicular to the first direction, and a first side part connected to a first side of the front part and defining a first side plane different from the front plane, and a rigid member partially overlapping the flexible member and on the front part.
METHOD FOR PRODUCING A MOULDED BODY
The present invention relates to a method for producing a molded body (10), comprising the following steps: a) providing a molding tool (40) which has at least one receptacle (12) in which at least one material (30) which comprises at least one shape-memory material (31) is introduced, wherein the shape-memory material (31) is present in a first state (111), wherein the material (30) at least partially fills the receptacle (12) of the molding tool (40) in such a manner that said material adjoins at least one surface of the receptacle (12); b) creating a molded body (10) in the receptacle (12) of the molding tool (40) from the material (30), wherein the shape-memory material (31) is present in a second state (112), wherein a form (11) is embossed into the molded body (10) during the second state (112); c) transferring the shape-memory material (31) to a third state (113), wherein the molded body (10) can be deformed during the third state (113) in such a manner that the molded body (10) is demolded from the receptacle (12) of the molding tool (40); and d) at least partially restoring the form (11) of the molded body (10) by transferring the shape-memory material (31) to a fourth state (114), wherein the molded body (10) at least partially resumes the form (11) according to step b) during the fourth state (114).
