Abstract
A medical device for placing an embolic coil at a preselected location within a vessel comprising a positioning catheter having a distal tip for retaining the embolic coil which when pressurized with a fluid expands outwardly to release the coil at the preselected position.
Claims23
A vasoocclusive coil deployment system for use in placing a coil at a preselected site within a vessel comprising:
- an elongated flexible catheter having a lumen extending therethrough and having a proximal section and a distal section;
- an embolic coil being disposed in fluid-tight engagement within the lumen of the distal section of the catheter;
- and,
- a source of fluid pressure coupled to the proximal section of the catheter for upon actuation applying fluid pressure to the lumen of the catheter to thereby release the embolic coil.
A vasoocclusive coil deployment system for use in placing a coil at a preselected site within a vessel comprising:
- an elongated flexible catheter having a lumen extending therethrough and having a proximal section and a distal section;
- an embolic coil being disposed in fluid-tight engagement within the lumen of the distal section of the catheter;
- and,
- a connector coupled to the proximal section of the catheter adapted to be connected to a source of fluid pressure which when applied through the connector to the lumen of the catheter causes the release of the embolic coil.
An implant device deployment system for use in placing a coil at a preselected site within a vessel comprising:
- an elongated flexible catheter having a lumen extending therethrough and having a proximal section and a distal section;
- an implant device being disposed in fluid-tight engagement within the lumen of the distal section of the catheter;
- and,
- a source of fluid pressure coupled to the proximal section of the catheter for upon actuation applying fluid pressure to the lumen of the catheter to thereby cause the release of the implant device.
