Untersuchung der Sicherheit und Funktion eines neuen Stentsystems das durch die Unterarmarterie eingesetzt werden kann und durch die Blutgefässe in den Oberschenkelbereich gebracht werden kann.

Data source: BASEC (Imported from 30.04.2024), WHO (Imported from 25.04.2024)

Disease category: Arterial and venous diseases including deep venous thrombosis and lung embolism

Brief description of trial (Data source: BASEC)

Die PAVK kann mit einer Änderung des Lebensstils, einer Ballonangioplastie, einem Stent oder einer Bypass-Operation behandelt werden. Patienten, deren Arzt der Meinung ist, dass Angioplastie und das Setzen eines Stents die geeignete Option zur Behandlung ihrer PAVK sind, können für diese Studie in Frage kommen.

Health conditions investigated(Data source: BASEC)

Die periphere arterielle Verschlusskrankheit (PAVK) ist eine Verengung der peripheren Arterien, die das Blut vom Herzen wegführen. PAVK wird durch die Ansammlung von Fettsubstanzen und/oder Kalkablagerungen in den peripheren Arterien verursacht. Dies kann den Blutfluss zu Geweben und Organen einschränken oder blockieren.

Intervention investigated (e.g. drug, therapy or campaign) (Data source: BASEC)

Wir wollen herausfinden, ob das S.M.A.R.T. RADIANZ Vascular Stent System (ein experimentelles Medizinprodukt) bei der Behandlung von PAVK sicher und wirksam ist, indem es den S.M.A.R.T. Nitinol Stent (der bereits von den europäischen Zulassungsbehörden genehmigt wurde) über einen Zugang in einer Arterie im Handgelenk in Arterien im Bauch und in den Beinen einbringt. Die Patienten, die an der Studie teilnehmen möchten, werden getestet, um festzustellen, ob sie für die Studie in Frage kommen. Wenn ja, wird ihnen der S.M.A.R.T. Nitinol Stent implantiert. Der Eingriff findet in einem Katheterlabor oder im Operationssaal unter sterilen Bedingungen statt. Der Eingriff dauert etwa 1.5 bis 3 Stunden, und der Patient bleibt danach noch etwa 0 bis 2 Tage im Krankenhaus. Etwa 30 Tage nach der Implantation des Geräts findet eine Nachuntersuchung im Krankenhaus statt.

Inclusion criteria 9 and 10 AND 11a through 14a OR 11b through 16b (whichever is
applicable) would be assessed via baseline angiography performed at the time of index
procedure:

9. The Investigator has assessed that the patient is a suitable candidate (i.e, meets all
inclusion criteria and none of the exclusion criteria), for treatment of a lesion in
the iliac, superficial femoral and/or proximal popliteal arteries via transradial
approach and is eligible for conversion from a transradial to transfemoral approach,
if it becomes necessary.

10. The guidewire is across the target lesion(s) and located intraluminally within the
distal vessel following a transradial approach

Patients whose target lesion is in the iliac artery must meet these additional criteria
prior to enrollment:

11a. A single de novo or restenotic lesion = 50% stenosis in the common and/or external
iliac artery

12a. Stenotic lesion (one long or multiple serial/tandem lesions) less than or equal to 100
mm, by visual assessment, within or across the common or external iliac arteries. The
stenosis must be treatable with no more than two stents (while minimizing stent overlap)

13a. Reference vessel diameter (RVD) ranging from 4.0 to 9.0 mm by visual assessment
