Patent number: 10232157Abstract: An article having at least one microneedle (160, 260) is provided. The microneedle includes a base (162), an elongated body (161) having a central axis (130) and a body diameter (168), a tip portion (166), and a hollow channel (170). The a tip portion includes a tip (164), a first bevel face (140) oriented diagonally with respect to the central axis and extending through at least 75% of the body diameter, a second bevel face (146) oriented substantially perpendicular to the central axis and intersecting the first bevel face, and a bevel opening defined by a first edge (174) of the first bevel face and a second edge (176) of the second bevel face. The hollow channel extends axially into the body from the bevel opening (172).Type: GrantFiled: July 10, 2014Date of Patent: March 19, 2019Assignee: 3M Innovative Properties CompanyInventors: Dennis G.

Patent number: 10201691Abstract: An article 100 comprising at least one microneedle 160 is provided. The article comprises a first side 112 and a second side 114 opposite the first side. The first side comprises a central cavity portion 120 and a platform portion 130, with at least one microneedle extending therefrom, wherein the platform portion is not coplanar with the central cavity portion. The platform portion substantially surrounds the central cavity portion. The at least one microneedle 160 comprises a body comprising an outer surface 163; a base segment 166 having a base and a first shape; a tip segment 168 having a tip 164 and a second shape, wherein the second shape is distinct from the first shape; a transition plane 167 that delineates the base segment and the tip segment; and a central axis.Type: GrantFiled: July 10, 2014Date of Patent: February 12, 2019Assignee: 3M Innovative PropertiesInventors: Dennis G.

Patent number: 10099043Abstract: An article 100 having a first side 112 that has a central portion 130 defined by a first edge 134, a microneedle-free peripheral portion 140 that substantially surrounds the central portion, and a plurality of spaced-apart hollow microneedles 160. Each microneedle has a body that includes an outer surface 163; a base segment 166 having a base 162 and a first shape; a tip segment 168 having a tip 164 and a second shape, wherein the second shape is distinct from the first shape; a transition plane 167 that delineates the base segment and the tip segment; and a central axis 180. An angle, defined by an intersection of the central axis of at least one microneedle and a shortest line extending from the first edge and through the transition plane of the at least one microneedle, is less than about 50°.Type: GrantFiled: July 10, 2014Date of Patent: October 16, 2018Assignee: 3M Innovative Properties CompanyInventors: Dennis G.
