Abstract
Expandable devices are disclosed herein. Several of the embodiments are directed towards an expandable device comprising a stent configured to be expanded within a body conduit of a human patient. The stent may comprise a tubular sidewall having first portions and second portions. Radial expansion of the stent may cause the first portions to bow outwardly and out of radial alignment with the second portions.
Claims18
An expandable device comprising:
- a stent comprising a tubular sidewall, the sidewall of the stent having first portions and second portions, wherein the stent has a collapsed configuration and an expanded configuration in which the device is configured to be positioned within a body conduit of a human patient at a treatment site, and wherein each of the second portions has a first end and a second end, each of the first and second ends connected to an adjacent first portion via a joint having a sinusoidal shape, and
- wherein transformation of the stent from the collapsed configuration to the expanded configuration causes the first portions of the sidewall to bow out of a cylindrical surface defined by the second portions of the sidewall such that, at least in the expanded configuration, the first portions form a plurality of buckled regions extending radially away from the second portions of the sidewall.
An expandable device comprising:
- a stent having a collapsed configuration and an expanded configuration in which the stent is configured to be positioned in a body conduit of a patient, the stent comprising a plurality of spines and a plurality of struts, the spines extending along a longitudinal axis of the stent and the struts extending between circumferentially adjacent spines, each of the spines having first portions and second portions along a respective length of the spine, wherein:
- in the collapsed configuration, the struts and the spines are the same radial distance from a central longitudinal axis of the stent and together define a cylindrical surface surrounding a lumen, and
- in the expanded configuration, (a) the struts and the first portions of the spines are a first radial distance from the central longitudinal axis, and (b) the second portions of the spines are a second radial distance from the central longitudinal axis, the second radial distance different than the first radial distance.
