Hydrodynamically propelled pacing catheter
First Claim
Patent Images
1. A hydrodynamically propelled pacing catheter of the type primarily used for insertion of permanent pacemaker leads into the hearts of patients, said pacing catheter comprising:
- an elongated flexible catheter tube for insertion through the patient'"'"'s blood vessels into the heart, said catheter tube having a cephalic end and a rearward end;
said cephalic end including a plurality of rearwardly facing ports substantially equally spaced around the perimeter thereof;
said catheter tube further having a fluid lumen disposed longitudinally inside said tube, a distal end of said fluid lumen being in fluid-communicating relation to said ports and a rearward end of said fluid lumen being defined by said rearward end of said catheter tube;
said catheter tube further having a side lumen formed therein substantially adjacent said rearward end in communicating relation to said fluid lumen whereby a second catheter may be connected to said pacing catheter for the introduction of a fluid through said fluid lumen and out said ports to impart a forward thrust to said cephalic end;
said pacing catheter further comprising a first pacing electrode, said first pacing electrode defining the tip of said cephalic end, a first electrical connector disposed on said rearward end of said catheter tube, and a first electrical conductor operatively disposed in interconnecting relation between said first pacing electrode and said first electrical connector, said first electrical connector being dimensioned and configured to operatively engage a source of electricity whereby an electrical stimulus may be applied to the patient'"'"'s heart.

Abstract
A hydrodynamically propelled pacing catheter primarily intended for use in the placement of permanent pacemaker leads into the heart of a patient. The cephalic end of the catheter is constructed to define a plurality of nozzle orifices for the expulsion of a pressurized fluid so that the catheter will be propelled through the patient'"'"'s vascular system into the heart. Dependent upon whether placement of the pacemaker lead is intended for the right atrium or the right ventricle, the catheter cephalic end will be curved or straight, respectively.
