| description | Methods, devices, and components are provided to reduce tissue resistive pressure during a subcutaneous drug delivery operation by increasing the size of the injection cavity by partially retracting the drug delivery member after inserting the drug delivery member to a subcutaneous position. The drug delivery devices described herein include a motor operably coupled to a drug delivery member. The motor can be selectively activated by a controller to retract the drug delivery member a predetermined distance to relieve pressure in an injection cavity in a patient. A force sensor can provide the controller with a drug delivery member insertion force. The controller can then estimate a tissue resistive pressure based on the drug delivery member insertion force and determine the predetermined distance for the partial drug delivery member retraction based on the tissue resistive pressure. |
