Abstract
Abstract Stent and stent delivery system suited for the noninvasive treatment of aneurysms, diseased blood vessels, and other bodily lumen are described. Detachable proximal and/or distal wires connected to the proximal and distal ends, respectively, of the stent allow the operator to manipulate the position and final configuration of the stent upon deployment.

Claims Analysis
Total Claims: 29
Claim 1
Independent Claim
53 words
A stent device having a proximal end and a distal end, the device comprising at least one detachable proximal wire connected to the proximal end and at least one detachable distal wire connected to the distal end, wherein the proximal wire is further attached to at least one additional location in the stent.
Claim 2
Dependent Claim
53 words
A stent device having a proximal end and a distal end, the device comprising at least one detachable proximal wire connected to the proximal end and at least one detachable distal wire connected to the distal end, wherein the proximal wire is further attached to at least one additional location in the stent.
Claim 3
Dependent Claim
31 words
The stent of claim 1 , wherein the detachable proximal wire comprises an electrolytically detachable end adapted to detach from the stent by imposition of a current on the proximal wire.
Claim 4
Dependent Claim
26 words
The stent of claim 1 , wherein the detachable proximal wire is adapted to detach from the stent using mechanical, hydraulic, ultrasonic or radio-frequency detachment mechanisms.
Claim 5
Dependent Claim
31 words
The stent of claim 1 , wherein the detachable distal wire comprises an electrolytically detachable end adapted to detach from the stent by imposition of a current on the distal wire.
Claim 6
Dependent Claim
26 words
The stent of claim 1 , wherein the detachable distal wire is adapted to detach from the stent using mechanical, hydraulic, ultrasonic or radio-frequency detachment mechanisms.
Claim 7
Dependent Claim
35 words
The stent of claim 1 , wherein the detachable distal and proximal wires comprise an electrolytically detachable end adapted to detach from the stent by imposition of a current on the proximal and distal wires.
Claim 8
Dependent Claim
28 words
The stent of claim 1 , wherein the detachable distal and proximal wires are adapted to detach from the stent using mechanical, hydraulic, ultrasonic or radio-frequency detachment mechanisms.
Claim 9
Dependent Claim
18 words
The stent of claim 1 , further comprising at least one insulator between the proximal and distal ends.
Claim 10
Dependent Claim
22 words
The stent of claim 1 , wherein the distal wire is further attached to at least one additional location in the stent.
Claim 11
Dependent Claim
24 words
The stent of claim 1 , wherein the distal and proximal wires are each further attached to least one additional site in the stent.
Claim 12
Dependent Claim
33 words
The stent of claim 10 , wherein the stent further comprises at least one insulator between the sites of attachment of the proximal wire and the sites of attachment of the distal wire.
Claim 13
Dependent Claim
18 words
The stent of claim 10 , wherein each additional site of attachment is via an electrolytically detachable link.
Claim 14
Dependent Claim
22 words
The stent of claim 10 , wherein the each addition site of attachment is via mechanical, hydraulic, ultrasonic or radio-frequency detachable link.
Claim 15
Dependent Claim
19 words
The stent of claim 1 , further comprising at least one aperture through which the distal wire is threaded.
Claim 16
Dependent Claim
11 words
The stent of claim 1 , further comprising a bioactive coating.
Claim 17
Dependent Claim
14 words
The stent of claim 15 , wherein the bioactive coating comprises a therapeutic agent.
Claim 18
Dependent Claim
12 words

Claim 19
Dependent Claim
12 words
The stent device of claim 1 , wherein the stent is self-forming.
Claim 20
Dependent Claim
72 words
The stent device of claim 18 , wherein the stent has a first substantially linear configuration for insertion into a restraining member and a second tubular configuration upon extrusion from the restraining member, the second tubular configuration comprising a plurality of turns, wherein the turns are not touching and further wherein the second tubular configuration has an outer diameter and at least a portion of the outer diameter conforms to the vasculature.
Claim 21
Dependent Claim
15 words
The stent of claim 19 , wherein the stent self-forms into the second tubular configuration.
Claim 22
Dependent Claim
14 words
The stent of claim 19 , wherein the restraining member comprises a deployment catheter.
Claim 23
Dependent Claim
29 words
The stent of claim 19 , wherein the stent further includes at least one aperture in each turn of the secondary configuration through which the distal wire is threaded.
Claim 24
Dependent Claim
63 words
A method of delivering a stent according to claim 19 to a selected site in a body cavity, the method comprising: (a) loading a substantially straightened stent according to claim 19 into a catheter; (b) accessing the selected site with the catheter; and (c) discharging the stent from the catheter at the selected site, wherein the stent forms a tubular configuration upon discharge.
Claim 25
Dependent Claim
13 words
The method of claim 23 , wherein the selected site is a lesion.
Claim 26
Dependent Claim
56 words
The method of claim 23 , wherein step (c) comprises: (i) pushing the stent out of the catheter by applying pressure to the proximal wire while keeping the stent in the desired location by applying tension to the distal wire; and (ii) applying electrical impulses sufficient to detach the distal and proximal wires from the stent.
Claim 27
Dependent Claim
15 words
The method of claim 25 , wherein step (c) further comprises: (iii) moving the catheter.
Claim 28
Dependent Claim
11 words
The stent device of claim 1 , further comprising a sheath.
Claim 29
Dependent Claim
16 words
The stent of claim 27 , wherein the sheath further includes at least one delivery wire.
