Abstract:
1. A microneedle delivery device, comprising: a hub housing having a proximate end and a distal end with a skin contact surface, said proximate end having a coupling member for removably coupling said device to a supply reservoir containing a substance to be delivered to a patient; a fluid communication member located at said proximate end of said housing and having a length sufficient to communicate with said supply reservoir, said fluid communication member mounted to said housing so as to be removable therewith, said fluid communication member terminating with a piercing member; a microneedle extending from said skin contact surface and having a length sufficient to penetrate the skin of a patient to a selected depth, said microneedle being separate, and spaced, from said fluid communication member, wherein a fluid flow path is defined between said supply reservoir and said selected depth, said microneedle defining the narrowmost portion of said fluid flow path; and a depth limiting member extending from said skin contact surface for limiting a depth of penetration of said microneedle into said skin.
