Abstract: This invention discloses a catheter comprising a first hollow tubular body of flexible non-kinking material having an entry and an exit port and a first lumen therethrough. A fixation balloon of soft elastomeric material is attached coaxially to the first hollow tubular body proximate the exit port. A second hollow tubular body of flexible non-kinking material having a second lumen therethrough is operatively attached at one end to the fixation balloon and at a opposite second end to means to selectively inflate or deflate the fixation balloon by applying pressure to a liquid contained in the second lumen. The second lumen provides a passageway for communicating pressure to inflate or deflate the fixation balloon to a liquid between the fixation balloon and the selective inflation and deflation means. Means are operatively coupled to the selective inflation and deflation means to limit the pressure supplied to inflate the fixation balloon through the second lumen to a selected pre-set pressure limit.
