Abstract

A diametrically adjustable endoprosthesis includes a controlled expansion element extending along at least a portion of a graft and is supported by a stent. The controlled expansion element diametrically constrains and limits expansion of the endoprosthesis. Upon deployment from a smaller, delivery configuration, the endoprosthesis can expand to the initial diameter set by the controlled expansion element. Thereafter, the endoprosthesis can be further diametrically expanded (e.g., using balloon dilation) by mechanically altering the controlled expansion element.

Claims (28)

1. A diametrically adjustable endoprosthesis having a compacted, delivery configuration, the diametrically adjustable endoprosthesis comprising:

a stent-graft including a stent and a base graft secured to the stent, the base graft having a first end and a second end and the stent-graft being self-expanding and exhibiting a self-expansion force, the stent-graft having a maximum diametric expansion limit; and

a controlled expansion element having a continuous wall extending for less than an entire length of the endoprosthesis when the endoprosthesis is in the compacted, delivery configuration, the controlled expansion element having an initial diametric expansion limit and being adjustable to an adjusted diameter through a range of diameters between the initial diametric expansion limit and the maximum diametric expansion limit when placed under an expansion force in addition to the self-expansion force of the stent-graft, the controlled expansion element being configured to maintain the adjusted diameter under physiological conditions following removal of the expansion force and the stent-graft being configured to limit the range of diameters for the adjusted diameter to the maximum diametric expansion limit.

2. The endoprosthesis of claim 1 , wherein the controlled expansion element defines a sliding interface with the stent-graft such that during diametric expansion of the endoprosthesis, the sliding interface between the controlled expansion element and the stent-graft permits at least a portion of the controlled expansion element to change in longitudinal dimension at a different rate than the stent-graft at the sliding interface.

3. The endoprosthesis of claim 1 , wherein the endoprosthesis has an inner lumen configured to convey biological fluid and further wherein the base graft defines the inner lumen of the endoprosthesis.

4. The endoprosthesis of claim 1 , wherein at the initial diametric expansion limit the controlled expansion element defines one or more tapers in diameter.

5. The endoprosthesis of claim 1 , wherein the controlled expansion element has a first end portion, a second end portion, and a central portion between the first and the second end portions, and further wherein at the initial diametric expansion limit the controlled expansion element includes the first end portion tapering outwardly to a first diameter and the second end portion tapering outwardly to a second diameter, and the central portion having smaller diameter than the first and second diameters.

6. The endoprosthesis of claim 1 , wherein the controlled expansion element includes a sleeve of controlled expansion material configured to deform upon application of the expansion force and to maintain the adjusted diameter under physiological conditions.

7. The endoprosthesis of claim 1 , wherein the base graft has a length and the stent-graft includes a lined region and an unlined region, the lined region corresponding to the length of the graft and the unlined region remaining uncovered.

8. The endoprosthesis of claim 7 , wherein the stent includes a section defining a chain-link pattern, the section corresponding to the unlined region of the stent-graft.

9. The endoprosthesis of claim 1 , wherein the controlled expansion element is mechanically coupled to the stent-graft.

10. The diametrically adjustable endoprosthesis of claim 1 , wherein the controlled expansion element extends for less than an entire length of the endoprosthesis when the endoprosthesis is in a delivery configuration.

11. A diametrically adjustable endoprosthesis comprising:

a stent-graft including a stent and a base graft secured to the stent, the base graft having a first end portion including a first end, a second end portion including a second end, and a central portion extending between the first end portion and the second end portion, the stent-graft being self-expanding and exhibiting a self-expansion force; and

a controlled expansion element having an initial diametric expansion limit defined by a delivery diameter, the controlled expansion element coupled to the stent-graft so that, at the initial diametric expansion limit, the first end portion tapers outwardly to a first diameter and the second end portion tapers outwardly to a second diameter so that the central portion has a smaller diameter than the first diameter and the second diameter, the controlled expansion element being continuously adjustable to an adjusted diameter throughout a range of diameters between the initial diametric expansion limit and the maximum diametric expansion limit when placed under an expansion force in addition to the self-expansion force of the stent-graft, the controlled expansion element being configured to maintain the adjusted diameter under physiological conditions following removal of the expansion force and the stent-graft being configured to limit the range of diameters for the adjusted diameter to the maximum diametric expansion limit.

12. A diametrically adjustable medical device, comprising:

a self-expandable member exhibiting a self-expansion force, the self-expandable member having a maximum diametric expansion limit; and

a controlled expansion element mechanically coupled to and extending for less than an entire length of the self-expandable member so that a sliding interface is defined between the controlled expansion element and the self-expandable member, the controlled expansion element having an initial diametric expansion limit and being adjustable to an adjusted diameter in a range of diameters between the initial diametric expansion limit and the maximum diametric expansion limit when placed under an expansion force in addition to the self-expansion force of the self-expandable member, the controlled expansion element being configured to maintain the adjusted diameter under physiological conditions following removal of the expansion force and the self-expandable member being configured to limit the range of diameters for the adjusted diameter to the maximum diametric expansion limit.

13. The diametrically adjustable medical device of claim 12 , wherein the controlled expansion element is configured to change in longitudinal dimension at a different rate than the self-expandable member at the sliding interface.

14. The diametrically adjustable medical device of claim 12 , wherein the controlled expansion element is coupled to the self-expandable member via interference fit.
