The expanded form of the implant has a configuration that fills the defect.

The balloon is then deflated, the distal tip of the guide catheter retaining its expanded shape.

The expanded form of the implant (16) has a configuration that fills the defect in the disc.

The injected fluid may polymerize so that the device is permanently held in its expanded form.

The sleeve includes a shape memory material such that the AED exists in a compact form in a first state and an expanded form in a second state.

Said wall includes a material that is plastically deformed in the bending zone during the bending process so that the expanded tubular section retains an expanded shape as a result of said plastic deformation.

The frame may expand from a conical deployment shape to a conical expanded shape, and may include web-like struts connected between axially-extending posts.

A medical implantable occlusion device (100, 200, 300) is disclosed comprising at least one thread (101) and a structural formation (102) thereof having a collapsed and 5 an expanded shape.

The AED is placed within the vessel while in the compact form and expanded into the expanded form such that the AED occludes the opening of the vascular malformation.

In the dilated form, the heart gets stretched out too much and cannot contract with as much force.

The holder, in the expanded form thereof, further comprises a first portion having a reduced first diameter, in which the function element can be detachably fitted.

Said element has a section, which expands at the increased temperature inside the anti-corrosion dipping bath and, afterwards, remains essentially in its expanded state at a normal temperature.

After insertion such an expanded shape is achieved by inflation of the balloon (18) through the use of an external source such as a syringe which introduces fluid through an opening and into the shaft.

In one aspect of the invention, the downhole apparatus is expanded by exposing the swellable material to at least one predetermined fluid, and the support structure abuts the swellable material in its expanded form.

A device for treating a fusiform aneurysm includes an elongate catheter and an expandable member detachably coupled with the elongate catheter at or near its distal end and adapted to assume a fusiform expanded shape.
