Abstract
A device and method for retrieving an electrode array. The medical device includes a catheter defining a proximal end, a distal end, and a lumen therethrough. A control wire slidably receivable within the lumen is included, the control wire defining a proximal end and a distal end, the distal end of the control wire defining an enlarged portion. A treatment portion receivable within the lumen is included, the treatment portion including a proximal portion adapted to receive the enlarged portion at the distal end of the control wire.
Claims12
A medical device, comprising:
- a catheter having a lumen extending between a proximal end and an open distal end;
- a control wire slidably receivable within the lumen, the control wire having a proximal end and an enlarged engagement element disposed at a distal end;
- a treatment portion collapsibly receivable within the lumen and having, at a proximal portion, a receptacle adapted to receive the enlarged engagement element.
A method of retrieving a medical device from within a human patient, the method comprising applying proximally-directed pulling force on a control wire extending through a catheter lumen such that an enlarged engagement element disposed at a distal end of the control wire transmits the proximally-directed pulling force to a distally-facing receptacle located in a proximal portion of a treatment portion to thereby draw the treatment portion proximally into the catheter lumen.
A medical device, comprising:
- a catheter defining a proximal end, a distal end, and a lumen therethrough;
- a control wire slidably receivable within the lumen, the control wire defining a proximal end and a distal end;
- an engagement element mounted on the distal end of the control wire, the engagement element defining an outer diameter larger than a diameter of the control wire;
- an expandable array assembly of electrodes receivable within the lumen, the assembly having a proximal portion and a tubular element compression fit thereto to define a distally-facing receptacle sized to receive the engagement element;
- and
- a coil slidably extending through the lumen and having a distal end abutting the tubular element.
