Abstract
Abstract This invention is directed to a member which is mounted on an elongated intraluminal device such as a catheter or a guidewire, preferably the proximal portion thereof, which releasably holds at least one turn of a coiled product. The coiled product may be the intraluminal device on which the fixture is mounted or it may be a separate product. In one embodiment of the invention, the turn holding member has a body and at least one flexible arm which holds a turn against the body of the fixture. In another embodiment of the invention, the holding member is a tubular element having a wall portion with a spirally shaped cutout through which a turn of coiled product can be advanced into the inner lumen or the tubular element.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
76 words
An elongated intravascular device comprising: a) a flexible elongated shaft having a distal portion which is configured to be advanced through a patient's vascular system and a proximal portion which extends out of the patient when the distal portion is advanced through the patient's vascular system; and b) means secured on the proximal portion if the flexible elongated shaft to releasably secure at least one turn of a coiled elongated element to maintain a coiled structure.
Claim 2
Dependent Claim
76 words
An elongated intravascular device comprising: a) a flexible elongated shaft having a distal portion which is configured to be advanced through a patient's vascular system and a proximal portion which extends out of the patient when the distal portion is advanced through the patient's vascular system; and b) means secured on the proximal portion if the flexible elongated shaft to releasably secure at least one turn of a coiled elongated element to maintain a coiled structure.
Claim 3
Dependent Claim
35 words
The elongated intravascular device of claim 1 wherein the means to releasably secure at least one turn of a coiled elongated element is a fixture having a body portion and at least one flexible arm.
Claim 4
Dependent Claim
18 words
The elongated intravascular device of claim 2 wherein the fixture has a pair of inwardly directed arms element.
Claim 5
Dependent Claim
26 words
The elongated intravascular device of claim 2 wherein the fixture has a single arm for releasably securing at least one turn of the coiled elongated element.
Claim 6
Dependent Claim
46 words
The elongated intravascular device of claim 1 wherein the means to releasably secure at least one turn of a coiled elongated element comprises a tubular member with a wall having a spirally shaped cutout therein which is adapted to receive a turn of the coiled product.
Claim 7
Dependent Claim
19 words
