Patent ID: 7981085

Claim:
A medical device comprising: a housing having a mounting surface adapted for application to the skin of a subject, a transcutaneous device with a distal pointed end portion adapted to penetrate the skin of the subject, the transcutaneous device having a first position in which the distal end portion is retracted within the housing, and a second position in which the distal end portion projects relative to the mounting surface, a user actuatable driver disposed within the housing and the driver adapted to move the transcutaneous device from the first position to the second position when the driver is actuated, wherein the driver, with the transcutaneous device arranged in the first position, is actuatable from a first state through an intermediate state to a second state, whereby actuation of the driver from the first state to the intermediate state causes activation of the driver, and actuation of the driver from the intermediate state to the second state causes release of the activated driver thereby moving the transcutaneous device from the first position to the second position.
