Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
142 words
A stent with a discontinuous expandable wall (1) comprising
on at least a portion of its length a continuous
covering layer (3) of elastic material being adhered to
the said portion of the discontinuous wall (1) of the
stent and being thereby intimately united with said wall
portion, said covering layer (3) having an outer surface
(4) surrounding the discontinuous wall (1), characterized
in that the continuous covering layer (3) of elastic
material is shaped into an outer cylindrical surface
(4) without irregularities that surrounds the discontinuous
wall at the outside and extends radially
within the said portion of the discontinuous wall (1)
and forms an inner surface following in a distance the
material parts of the discontinuous wall in places with
material parts and following the cylindrical outer surface
in places without material parts thereby forming an
inner surface with irregularities.
Claim 2
Dependent Claim
104 words
A method for applying the covering layer of the
stent according to claim 1, characterized
by the steps of : radially contracting the stent, inserting at least a portion of the contracted stent
into a tube the inner surface of which has been previously
done over with a lifting medium, allowing the stent to radially expand in the tube, wetting the assembly tube plus stent with an elastomeric
polymerisable composition dissolved in a sufficient
amount of solvent to permit wet forming, evaporating the solvent, polymerising the elastomeric composition in the
tube, and taking the layer covered portion of the stent out
of the tube.
Claim 3
Dependent Claim
37 words
A method according to claim 2, wherein said tube
is first wetted alone
with the elastomeric composition added with solvent,
and wherein the solvent is evaporated before the step
of insertion of the stent into the tube.
