Abstract
The instant disclosure relates to a family of devices and methods for both measuring electrophysiological signals and delivering elongate medical devices. In an embodiment, a kit is described that includes a hollow catheter adapted to navigate a patient's vasculature having a hollow lumen terminating at a distal end, structure configured for sensing cardiac electrical activity adjacent the distal end of the hollow catheter and for acquiring electrograms. The fossa ovalis of a subject can be located therefrom and a second medical device can be advanced into and through the hollow lumen to such an extent that a distal tip of the second medical device protrudes beyond a proximal end and the distal end of the hollow catheter at the same time.
Claims20
An apparatus comprising:
- a hollow catheter comprising a hollow lumen terminating at a distal end;
- means for measuring cardiac electrical activity coupled to the distal end of the hollow catheter, wherein the hollow catheter is navigable through a patient's vasculature;
- and
- wherein said hollow lumen is adapted to receive a second medical device having a length greater than that of the hollow catheter.
An apparatus comprising:
- a hollow catheter adapted to navigate a patient's vasculature to the right atrium, wherein the hollow catheter surrounds a hollow lumen terminating at a distal end;
- and
- means for measuring cardiac electrical activity coupled to the distal end of the hollow catheter;
- wherein the hollow lumen is configured to receive a second medical device there through.
A kit comprising:
- a hollow catheter adapted to navigate a patient's vasculature having a hollow lumen terminating at a distal end;
- means for sensing cardiac electrical activity adjacent the distal end of the hollow catheter;
- means for acquiring electrograms and locating the fossa ovalis therefrom in operable communication with the means for sensing cardiac electrical activity;
- and
- a second medical device advanceable into and through the hollow lumen to such an extent that a distal tip of the second medical device protrudes beyond a proximal end and the distal end of the hollow catheter at the same time.
