Abstract: A device for delivery of agent to a biological barrier may comprise a petal bearing main body having a set of guides each having an upstream and downstream portion. The device may further comprise a reservoir including at least one delivery sharp. The device may further comprise a plunger having a set of plunger protrusions each disposed in a respective guide. The device may further comprise a first bias member urging the plunger toward a position in which the protrusions are at an end of the downstream portions. The device may further comprise a trigger body with a first and second set of barriers. The trigger body may be displaceable between a position in which the second barriers are stowed and the first barriers obstruct displacement of the protrusions and another position in which the first barriers are stowed and the second barriers obstruct travel of the protrusions.

Abstract: A delivery device for delivery of medical agent to a barrier may comprise a main body including a central region defining a receptacle, a peripheral region defined by a number of petal members, and a set of retention tabs extending into the receptacle. The delivery device may further comprise a reservoir including at least one delivery sharp, a main interior volume, and at least one septum in fluid communication with the main interior volume. The reservoir may be coupled to the main body via the retention tabs. The delivery device may further comprise an adhesive coupled to the main body. The delivery device may further comprise at least one bias member positioned within the receptacle between the reservoir and a wall of the receptacle.

Abstract: An access assembly for administration of agent to a shallow delivery destination may comprise a body having a first exterior surface and a second exterior surface. The first exterior surface may be at a non-orthogonal angle to the second exterior surface. The body may have a passage extending therethrough to a corner formed between the first and second exterior surfaces. The assembly may further comprise an adhesive pad coupled to the second exterior surface. The assembly may further comprise a member having a flow path extending therethrough and a sharp bearing body including a number of microneedles coupled to an end of the member. The member may be disposed within the passage and in contact with at least one stop defined by the passage. The assembly may further comprise a coupler configured to couple with a cooperating coupler on a fluid flow conduit.

Abstract: A medical agent administration device may comprise a main body including a central region and a peripheral region. The peripheral region may have a plurality of petal members extending outwardly from the central region. The device may further comprise at least one coupling on a first face of the central region. The device may further comprise at least one sharp bearing body on an opposing face of the central region. Each of the at least one sharp bearing body may be in fluid communication with a respective one of the at least one coupling.

Abstract: A delivery device may comprise a main body. The main body may comprise a peripheral region. The main body may further comprise a central region extending proud of the peripheral region. The peripheral region may have a top surface and a base. The peripheral region may include a number of bodies spaced apart by slits which extend from the periphery of the peripheral region toward the central region. The delivery device may further comprise an adhesive coupled to at least a part of the main body. The delivery device may further comprise a collapsible reservoir coupled to the main body and to at least one delivery sharp.

Abstract: Apparatus for continuously micro-embossing a seamless precision optical pattern onto a moving substrate without the use of an intermediate layer, comprising an energy source, such as a laser, along with reduction optics, a mask and a moving substrate. The moving substrate provides both precision linear and rotational movement which motion is coupled with the laser projection imaging episode. Etched patterns can therefor be continuously and precisely ablated in the substrate to substantially cover the entire surface to uniquely micro-emboss therein a seamless precision optical image.
