Get professional therapy (7)
I believe the answer is:
procure
'get' is the definition.
(I know that procure is a more specific form of the action capture)
'professional therapy' is the wordplay.
'professional' becomes 'pro' (abbreviation).
'therapy' becomes 'cure' (cure is a kind of therapy).
'pro'+'cure'='PROCURE'
(Other definitions for procure that I've seen before include "Acquire" , "Get by special effort" , "Obtain; solicit" .)
