Abstract
An endoluminal device can comprise a flexible tubular wall and a frame member. The frame member can be comprised of a shape-memory material having sides with protrusions which are partially or substantially flattened when formed together with the flexible tubular wall to thereby create a bias in the side wall of the endoluminal device that resists deformation from a desired device profile during crush loading and is thereby resistant to invaginations when deployed.
Claims20
A method of treatment comprising:
- positioning an endoluminal device in a vasculature of a patient, the endovascular device including,
- a frame, and
- a flexible tubular wall coupled to the frame;
- and
- deploying the endoluminal device at a target location in a vasculature of a patient including expanding the endoluminal device with at least one protrusion of the frame that is radially constrained by the flexible tubular wall to produce an outward bias in a portion of the device that resists radial deformation of the endoluminal device.

A method of treatment comprising:
- positioning an endoluminal device in a vasculature of a patient, the endovascular device including,
- a frame having a generally conical shape and at least one protrusion that projects radially from the frame in an unconstrained state, and
- a flexible tubular wall configured to couple or secure to a portion of the frame to constrain the frame from the generally conical shape to a substantially cylindrical shape to create an internal structural bias that resists inward deflection of the endoluminal device in a constrained state;
- and
- deploying the endoluminal device at a target location in a vasculature of a patient.
2 more elements
A method of making an endoluminal device, the method comprising:
- forming a frame on a first mandrel, the first mandrel having one or more protrusions, the frame having a generally conical shape;
- wrapping a flexible tubular wall about the frame on a second mandrel;
- and
- applying the flexible tubular wall to the frame, the frame transitioning to a substantially cylindrical shape upon application of the flexible tubular wall such that an internal structural bias is created in the frame to resist inward deformation.
