Intracorporeal occlusive device and method

摘要

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.

主权项

1. A delivery system for an intracorporeal device comprising:
an elongated shaft having an inner lumen; a degradable link associating the elongated shaft and an intracorporeal device without covering an external circumference of the intracorporeal device, a portion of the degradable link disposed within the inner lumen of the elongated shaft; and at least one signal transmission element disposed within the inner lumen of the elongated shaft, the at least one signal transmission element operable to transmit a direct current to initiate degradation of the degradable link thereby completely disassociating the intracorporeal device from the elongated shaft.
