Abstract
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.

Claims Analysis
Total Claims: 29
Claim 1
Independent Claim
91 words
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.
Claim 2
Independent Claim
91 words
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.
Claim 3
Dependent Claim
25 words
The method of claim 1 , wherein: the dissolving step is carried out by delivering the fluid to the material to dissolve the dissolvable material.
Claim 4
Dependent Claim
22 words
The method of claim 2 , wherein: the dissolving step is carried out with the fluid being delivered through the delivery element.
Claim 5
Dependent Claim
61 words
The method of claim 3 , wherein: the dissolving step is carried out with a tube positioned in the delivery element, the tube having a lumen, the tube and delivery element defining a space therebetween, the fluid being delivered through one of the lumen and the space and the fluid being withdrawn through the other of the lumen and the space.
Claim 6
Dependent Claim
19 words
The method of claim 1 , wherein: the providing step is carried out with the occlusion element forming coils.
Claim 7
Dependent Claim
20 words
The method of claim 1 , wherein: the providing step is carried out with the dissolvable material having a cavity.
Claim 8
Dependent Claim
19 words
The method of claim 6 , wherein: the providing step is carried out with the cavity being a throughhole.
Claim 9
Dependent Claim
47 words
The method of claim 1 , further comprising the step of: positioning a blocking element to impede fluid contact with a least a protected portion of the dissolvable material, the blocking element being movable to a position spaced apart from the protected portion of the dissolvable material.
Claim 10
Dependent Claim
19 words
The method of claim 8 , wherein: the blocking element is positioned in a cavity in the dissolvable material.
Claim 11
Dependent Claim
25 words
The method of claim 1 , wherein: the providing step is carried out with the occlusion element having a portion embedded in the dissolvable material.
Claim 12
Dependent Claim
69 words
The method of claim 10 , wherein: the providing step is carried out with the embedded portion being embedded in the dissolvable material in an expanded position, the embedded portion being naturally biased toward a collapsed position; and the dissolving step is carried out so that the portion of the occlusion element is no longer embedded in the material thereby permitting the portion to move toward the collapsed position.
Claim 13
Dependent Claim
25 words
The method of claim 10 , wherein: the providing step is carried out with the portion embedded in the material including a plurality of filaments.
Claim 14
Dependent Claim
24 words
The method of claim 10 , wherein: the providing step is carried out with the portion embedded in the dissolvable material being a coil.
Claim 15
Dependent Claim
28 words
The method of claim 1 , wherein: the providing step is carried out with the occlusion element having a plurality of flexible fibers embedded in the dissolvable material.
Claim 16
Dependent Claim
23 words
The method of claim 1 , wherein: the providing step is carried out with the portion embedded in the material including a ball.
Claim 17
Dependent Claim
23 words
The method of claim 1 , wherein: the providing step is carried out with the portion embedded in the material including a cage.
Claim 18
Dependent Claim
26 words
The method of claim 1 , wherein: the providing step is carried out with a flexible sheath covering at least a portion of the dissolvable material.
Claim 19
Dependent Claim
19 words
The method of claim 17 , wherein: the providing step is carried out with the sheath having openings therein.
Claim 20
Dependent Claim
49 words
The method of claim 18 , wherein: the providing step is carried out with the delivery element having a fluid distributing portion with openings for distributing the fluid; the dissolving step being carried out to deliver the fluid through the openings in the distributing portion to dissolve the material.
Claim 21
Dependent Claim
19 words
The method of claim 19 , wherein: the providing step is carried out with the distributing portion being conical.
Claim 22
Dependent Claim
34 words
The method of claim 1 , further comprising the step of: moving the delivery element relative to the occlusion element after the dissolving step to fully release the occlusion element from the delivery element.
Claim 23
Dependent Claim
19 words
The method of claim 1 , wherein: the dissolving step fully releases the occlusion element from the delivery element.
Claim 24
Dependent Claim
51 words
The method of claim 1 , wherein: the providing step is carried out with the occlusion element having a blocking portion which isolates the material from the patient's blood; the advancing step being carried out so that the blocking portion isolates the material from the patient's blood during the advancing step.
Claim 25
Dependent Claim
22 words
The method of claim 23 , wherein: the providing step is carried out with the blocking portion being a plug of material.
Claim 26
Dependent Claim
20 words
The method of claim 24 , wherein: the providing step is carried out with the plug of material being solder.
Claim 27
Dependent Claim
20 words
The method of claim 23 , wherein: the providing step is carried out with the blocking portion being a disc.
Claim 28
Dependent Claim
32 words
The method of claim 1 , wherein: the dissolving step is carried out with the fluid being a fluid selected from the group consisting of water, saline and the patient's own blood.
Claim 29
Dependent Claim
30 words
The method of claim 1 , wherein: the providing step is carried out with the material being selected from the group consisting of sugar, salt, manitol or a combination thereof.
