18 Claims

1. A fluid delivery device, comprising: a fluid reservoir; a transcutaneous access tool fluidly coupled to the fluid reservoir, the transcutaneous access tool including a needle and a cannula; a glucose monitoring device, wherein the fluid reservoir, the transcutaneous access tool, and the glucose monitoring device are located within a housing, and wherein at least a portion of the transcutaneous access tool and the glucose monitoring device are configured to extend from the housing and into a patient; and an insertion and retraction mechanism within the housing, the insertion and retraction mechanism comprising: a spring defining a longitudinal axis; and a first linkage and a second linkage coupled between the spring and a first sliding member, wherein the first sliding member is coupled with the needle, wherein the first and second linkages are configured to move the first sliding member in an insertion direction and a retraction direction in response to a force from the spring, and wherein the first linkage includes a first end adjacent the spring and a second end directly coupled to the second linkage; and a frame operable to lock the first sliding member and a second sliding member in a pre-deployment position and to lock the second sliding member in a post-deployment position, wherein the needle is located within the cannula such that the cannula remains deployed when the needle is retracted.
