Abstract
An intracorporeal space filling device and a delivery system and method for using the device is disclosed. The space filling device is preferably configured for percutaneous delivery from a peripheral conduit of a patient. The space filling device has an elongated tubular or interconnected bead structure which may have a transmutable material disposed within it. The transmutable material can be altered from a non-rigid state to a rigid state by the application of various types of energy or by other suitable means. The space filling device can be positioned by a delivery system and detached from the delivery system after desired positioning is achieved.
Claims19
A method for delivering an intracorporeal space filling device to a desired site within a patient's vasculature comprising the following steps performed in the following order:
- (a) advancing an intracorporeal space filling device having a first end detachably secured to a distal end of an elongated shaft to a desired site within a patient's vasculature;
- (b) heating a resistive element;
- (c) heating a polymer link detachably securing the first end of the intracorporeal space filling device to the distal end of the elongated shaft through the heating of the resistive element;
- (d) releasing the intracorporeal space filling device from the distal end of the elongated shaft through the heating of the polymer link;
- and
- (e) withdrawing the elongated shaft from the intracorporeal space filling device.

- (c) releasing the intracorporeal space filling device from the distal end of the elongated shaft through the heating of the non-tubular polymer link;
- and
- (d) withdrawing the elongated shaft from the intracorporeal space filling device.
A delivery system for an intracorporeal space filling device comprising:
- an elongated shaft;
- a polymer link detachably securing an intracorporeal space filling device to the elongated shaft, a portion of the polymer link passing through and out from a lumen of the elongated shaft;
- a resistive element in thermal contact with the polymer link;
- and
- a source of direct current in electrical communication with the resistive element through a signal conduit.
