METHOD FOR DEPLOYING A STENT DELIVERY SYSTEM HAVING A BLOWMOLDED HOLDER
First Claim
1. A method for deploying a stent, wherein the stent is configured to expand from a compressed state to an expanded state, comprising:
- delivering the compressed stent placed on a blowmolded holder and the holder into a predetermined deployment site,wherein the holder is blowmolded onto an inner surface of the compressed state, the holder contacting the inner surface and at least portions of side surfaces of the stent, the holder and the stent thereby having an interference fit therebetween;
releasing the stent from interference with the holder; and
expanding the stent from the compressed stent to the expanded stent.

Abstract
A method for deploying a stent delivery system having a blowmolded holder is provided. The stent is configured to expand from a first diameter to a second diameter. The holder is blowmolded to an inner surface of the compressed state. The holder contacts the inner surface and at least portions of side surfaces of the stent, and the holder and the stent have an interference fit therebetween. The deployment method includes delivering the compressed stent placed on the blowmolded holder and the holder into a predetermined deployment side. The deployment method further includes releasing the stent from interference with the holder and expanding the stent from the compressed stent to the expanded stent.

6. A method for deploying a sheathless stent delivery system comprising a stent disposed on a blowmolded holder wherein the stent is configured to expand from a compressed state to an expanded state,
wherein the blowmolded holder of the sheathless stent delivery system comprises: -
a cylindrical body; and a plurality of edges integrally formed with the cylindrical body and two neighboring edges extending toward a strut of the stent and wrapping around at least a portion of the strut of the stent on opposite sides of the strut, wherein the edges radially inwardly press over the stent and contact a portion of a radially outwardly exposed side surface of the strut of the stent and simultaneously restricts longitudinal movement of the stent relative to the holder; wherein a selected diameter of the holder at the edges is approximately the same as an outer diameter of the stent as a whole in the compressed state; the method comprising; delivering the compressed stent and the holder to a deployment site by threading the holder over a wire through an interior of the holder, releasing the stent from interference with the blowmolded holder by using a stimulator; and expanding the stent from the compressed stent to the expanded stent. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)

14. A method for deploying a sheathless stent delivery system comprising a stent disposed on a blowmolded holder wherein the stent is configured to expand from a compressed state to an expanded state,
wherein the blowmolded holder of the sheathless stent delivery system comprises: -
a cylindrical body; and a plurality of patterns or impressions integrally formed with an outer diameter of the cylindrical body, the plurality of patterns or impressions wrapping around at least a portion of a strut of the stent in the compressed state with a first edge and a second edge of two neighboring patterns or impressions on opposite sides of the strut, wherein the first and the second edges extend toward the strut of the stent disposed between the two neighboring patterns or impressions; wherein the first and the second edges radially inwardly press over the strut of the stent and contact a portion of a radially outwardly exposed side surface of the strut of the stent and simultaneously restricts longitudinal movement of the stent relative to the holder; the method comprising; delivering the compressed stent and the holder to the deployment site by threading a wire through an interior of the holder; providing a stimulator attached to the wire to a predetermined deployment site, the wire extending from a proximal end to a distal end; stimulating an inner surface of the holder by retracting the stimulator toward the proximal end, wherein a diameter of the stimulator is larger than an inner diameter of the holder; and releasing the stent from interference with the blowmolded holder. - View Dependent Claims (15, 16, 17, 18, 19)
