Abstract: An infusion device according to certain embodiments is provided for subcutaneous delivery of a therapeutic agent to a patient. The infusion device generally includes a cannula and a hub part. The cannula includes a tubular body member including a tubular wall at least partly enclosing a longitudinally-extending internal bore. A distal portion of the tubular body member includes a distal tip end including at least one tip opening. The tubular wall includes at least two weakened portions capable of allowing the cannula to flex in an area including the weakened portions when the cannula is exposed to a compression force and/or an increased internal pressure. The hub part is configured to be fastened onto the patient's skin via a mounting pad.

Abstract: Infusion devices including a cannula have a tubular body member comprising a tubular wall enclosing a longitudinal extending internal bore. The cannula is adapted to flex in response to a compression force and/or an increased internal pressure in the cannula.
