Closing long pending interview process?

Wondering how do u approach this?

Got to final stage interviews, it's been long and smooth process with 2 companies and then at the last stage when recruiter needs to put offer together, both Recruiter and HM has been pushing meetings and delaying.  Quite likely I am an expensive candidate in their pack. My guess is that they are keeping me warm while trying to progress some other candidates through the process. 

how would you create sense of urgency without looking too desperate ? to move this to closure.
