Abstract
A device for delivering an occlusion element, or other medical device, which includes a fluid dissolvable bond. The occlusion element is coupled to the delivery element with the fluid dissolvable bond. The bond may be dissolved by delivering a fluid through the delivery element either through the delivery element itself or through a tube positioned in the delivery element.
Claims65
A method of delivering an occlusion element, comprising the steps of:
- providing an occlusion element which is coupled to a delivery element with a dissolvable material, the dissolvable material being dissolvable with a fluid, the dissolvable material forming a dissolvable connection between the delivery element and the occlusion element;
- advancing the occlusion element through a patient's vascular system with the occlusion element coupled to the delivery element with at least the dissolvable connection;
- and
- dissolving the dissolvable material thereby releasing the occlusion element from the dissolvable connection with the delivery element, wherein the dissolving step is carried out with the dissolvable material being dissolved faster by the fluid as compared to other fluids contacting the material during the advancing step.
