A system including a polymeric sheet. The polymeric sheet comprises a base sheet having a first surface and a second surface opposite the first surface and a multiplicity of spaced rails projecting from the first surface of the base sheet. The rails comprise a stem portion attached to and substantially upright from the first surface of the base sheet and a top portion on the distal end of the stem opposite the base sheet. The top portion comprises a first surface opposite the base sheet and a second surface facing the first surface of the base sheet. Additionally, the rails have a length greater than the width of the stems. The first surface of the base sheet, the second surface of the top portion and the surface of the stem defines a cavity with walls, and an adhesive coated on at least a portion of the cavity wall.

A flexible hook hanger comprises an elongate sheet of pliable backing, an adhesive layer and a hook element. The backing comprises first and second ends, a first zone positioned adjacent the first end, a second zone positioned adjacent the second end and a central zone positioned between the first and second zones. The adhesive layer is disposed on one side of the backing. The hook element is connected to the central zone. In one embodiment, the pliable backing comprises microstructured tape, and the adhesive layer comprises a pressure sensitive adhesive composition comprising one or more hydrocarbon block copolymers, and a polar phenolic tackifier. In another embodiment, at least one of the first and second zones includes a peel arrestor. For example, the first zone and the second zone have a first width and a second width, respectively, and the central zone has a third width that is less than at least one of the first width and the second width.

A polycaprolactone fumarate copolymer useful as a material for a biocompatible scaffold for tissue engineering applications is disclosed. The copolymer includes at least one caprolactone unit, at least one fumarate unit, and at least one third unit selected from the group consisting of acrylate units and styrenic units. A linking moiety forms a link between the third unit and at least one caprolactone unit or at least one fumarate unit. The linking moiety can be photodegradable. In one form, the third unit includes at least one methyl methacrylate unit. The copolymer can be used to form the wall of a nerve conduit.

Photodegradable polycaprolactone fumarate block copolymers

A polycaprolactone fumarate polymer useful as a matrix material for a biocompatible scaffold for tissue engineering applications is disclosed. The polycaprolactone fumarate polymer can be prepared by reacting caprolactone with an alkane polyol to prepare a polycaprolactone precursor, and then reacting the polycaprolactone precursor with fumaric acid or a salt thereof to prepare the polycaprolactone fumarate polymer. The use of an alkane diol, such as 1,2-propanediol, provides a linear polycaprolactone diol precursor. The use of an alkane triol, such as glycerol, provides a branched polycaprolactone triol precursor. The biocompatible polycaprolactone fumarate formulation releases no diethylene glycol or other undesirable byproducts during degradation.

An adhesive mounting article includes a flexible adhesive tape structure having a first major surface and a second major surface opposite to the first major surface. The flexible adhesive tape structure includes a peelable adhesive layer disposed on the first major surface and a first separable connecting member disposed on the second major surface. The peelable adhesive layer is capable of adhering to a mounting surface and thereafter being manually removable from the mounting surface by peeling. A rigid faceplate structure includes a rigid faceplate having a first major surface and a second major surface opposite to the first major surface, and a second separable connecting member disposed on the first major surface of the rigid faceplate. The first and second separable connecting members engage with each other to form a separable connection to connect the flexible adhesive tape structure and the rigid faceplate structure.
