Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
54 words
Device for introduction into a human or animal body,
especially into an artery, specifically to be positioned in
an aneurysmal sac in an artery between the wall of the artery
and the wall of an endoprosthesis, comprising at least a
pressure sensor and a transponder for wireless transmitting
data available from the pressure sensor.
Claim 2
Dependent Claim
23 words
Device according to claim 1, wherein the device has
outer dimensions such that it can be introduced into said
artery through a catheter.
Claim 3
Dependent Claim
21 words
Device according to claim 1 or 2, wherein the
pressure sensor and the transponder are interconnected,
preferably provided within one housing.
Claim 4
Dependent Claim
61 words
Device according to any one of the preceding claims,
wherein the pressure sensor has a range of at least 50-150 mm
Hg (6.67 * 10 3 Pa - 20.0 * 10 3 Pa), preferably between 25-175
mm Hg (3.3 * 10 3 Pa - 23.3 * 10 3 Pa), more specifically 0-220
mm Hg (0 - 29.3 * 10 3 Pa).
Claim 5
Dependent Claim
23 words
Device according to any one of the preceding claims,
wherein the device comprises means for storing data,
connected to at least the transponder.
Claim 6
Dependent Claim
32 words
Device according to any one of the preceding claims,
wherein means are provided for positioning the device in a
stable position within an artery, especially within an
aneurysmal sac in an artery.
Claim 7
Dependent Claim
25 words
Device according to claim 6, wherein the positioning
means are provided for positioning the device at least partly
within blood, clogged in an aneurysmal sac.
Claim 8
Dependent Claim
21 words
Device according to claim 6, wherein the positioning
means are provided for positioning the device at least partly
on an endoprosthesis.
Claim 9
Dependent Claim
15 words
Set of a device according to any one of the preceding
claims and an endoprosthesis.
Claim 10
Dependent Claim
17 words
Set according to claim 9, wherein the endoprosthesis
is an endovascular prosthesis for use in the abdomen.
Claim 11
Dependent Claim
42 words
Set according to claim 9 or 10, further comprising
means for introduction into an artery, into which the device
has to be introduced, especially catheter means, the device
having such outer dimensions that this can be pushed through
said means for introduction.
Claim 12
Dependent Claim
20 words
Set according to claim 11, wherein the means for
introduction comprises means for positioning the device in an
aneurysmal sac.
Claim 13
Dependent Claim
53 words
Set according to any one of claims 9-12, wherein
means are provided for exiting the transponder when
positioned in an artery of a human or animal, wherein
furthermore means are provided for reading data transmitted
from the pressure sensor and/or data means through the
transponder to the outside of said human or animal.
Claim 14
Dependent Claim
20 words
Use of a miniaturized pressure sensor and transponder
attached thereto, for introduction into an artery of a human
or animal.
Claim 15
Dependent Claim
55 words
Method for measuring pressure in an artery of a human
or animal body, especially in an aneurysmal sac therein,
whereby a pressure sensor and a transponder attached thereto
are positioned in said artery, the transponder being arranged
for wireless transmitting pressure data from the pressure
sensor to detecting means outside said human or animal body.
Claim 16
Dependent Claim
55 words
Method according to claim 15, wherein the pressure
sensor and transponder are brought into said artery by means
of a catheter, whereby an endoprosthesis is brought into said
artery in a position over the pressure sensor and
transponder, thus enclosing said pressure sensor and
transponder in between the wall of said artery and said
endoprosthesis.
Claim 17
Dependent Claim
17 words
Use of a catheter for introduction of a sensor and
transponder into a human or animal body.
