Abstract
An infusion system comprising: a device for delivering fluid to a tissue of the user; a hub engaging the device for delivering fluid, the hub including an introducer needle for introducing an infusion catheter or an analyte sensor into the tissue of the user, the hub configured to be removable by the user; and an activation mechanism for moving the hub toward the user to thereby cause the introducer needle to be inserted into the tissue of the user.
Claims20
An infusion system comprising:
- a device for delivering fluid to a tissue of the user;
- a hub engaging the device for delivering fluid, the hub including an introducer needle for introducing an infusion catheter or an analyte sensor into the tissue of the user, the hub configured to be removable by the user;
- and
- an activation mechanism for moving the hub toward the user to thereby cause the introducer needle to be inserted into the tissue of the user.

An infusion system comprising:
- a device for delivering fluid to a user, the device including a pump for pumping the fluid into a tissue of the user;
- a cartridge assembly including an infusion catheter and an analyte sensor to be inserted into the tissue of the user, the needle cartridge assembly configured to move from (1) a first position, wherein infusion catheter and analyte sensor are in a retracted position above the tissue of the user to (2) a second position, wherein the infusion catheter and analyte sensor are in a deployed position inserted into the tissue of the user;
- and
- a hub configured to engage the cartridge assembly and to be removed from the cartridge assembly, the hub including first and second introducer needles for introducing the infusion catheter and the analyte sensor, respectively into the tissue of the user.

An infusion system comprising:
- a device for delivering insulin to a user, the device including a pump for pumping the insulin into a subcutaneous tissue layer of the user;
- a cartridge assembly including an infusion catheter and an analyte sensor to be inserted into the subcutaneous tissue layer of the user, the needle cartridge assembly configured to move from (1) a telescoping position above the top surface of device, wherein the introducer needle is in a retracted position within the device for delivering insulin to the user and (2) an advanced position within the device, wherein the introducer needle is in a deployed position inserted into the subcutaneous tissue layer of the user along with the catheter and the analyte sensor;
- a hub configured to be removed from the cartridge assembly, the hub including first and second introducer needles for introducing the infusion catheter and the analyte sensor, respectively into the subcutaneous tissue layer of the user;
- and
- a detachable activation mechanism for causing the cartridge assembly to move from (1) the telescoping position to (2) the advanced position within the device.
