Abstract
A circuit system includes a user interface, voltage source, and a terminal bank connected to the voltage source. The circuit can be used in a powered catheter system where the catheter includes a structural reinforcement layer such as a braid comprised of one or more wires. The reinforcement layer can be used to convey a current or signal in a powered catheter. The catheter may utilize a hypotube element which provides integrated sensors in order to power and control multiple systems in the powered catheter.
Claims15
A catheter comprising:
- an elongated tubular portion having a proximal end, a distal end, and forming a continuous inner lumen spanning from said proximal end to said distal end;
- a plurality of wires extending between said proximal end and said distal end;
- a hypotube located at said distal end of said elongated tubular portion;
- said hypotube having a proximal edge that is proximally facing toward said proximal end of said elongated tubular portion;
- said proximal edge comprising a plurality of notched areas formed by cutout portions extending completely radially through said hypotube between an exterior of said hypotube and an interior of said hypotube, and longitudinally into said proximal edge of said hypotube;
- said notched areas being electrically joined to a distal end of one or more of said plurality of wires so as to create a snug electrical connection with said hypotube;
- said hypotube comprising one or more electrical paths;
- one or more electrically powered components connected to said hypotube and in electrical communication with one or more of said electrical paths;
- and,
- an interface connectable to said proximal end of said elongated tubular portion to supply power to said hypotube via at least two of said plurality of wires.
