Description

Indication

Contraindication

1,2

Palmaz Genesis Transhepatic Biliary Stent

Unmounted, balloon-expandable; laser cut stent made from 316L stainless steel tubing.

Palliation of malignant neoplasms in the biliary tree

- Stenting of a perforated duct where leakage from the duct could be exacerbated by the prosthesis;

- Patients with bleeding disorders or who cannot receive anticoagulants

- Severe ascites

3

Jostent coronary stent graft

High grade surgical stainless steel (316L) manufactured from a solid tube using precision laser technology adjacent to expandable PTFE graft material.

Free coronary perforations defined as free contrast extravasation into the pericardium, in native coronary vessels or saphenous vein bypass grafts greater than or equal to 2.75mm in diameter

- Bleeding disorders;

- Inability to take anticoagulants;

- A lesion which prevents complete inflation of an angioplasty balloon

4,5,6

Intrastent Mega LD and Max LD Biliary stents

Balloon expandable stents made from a stainless steel tube cut into an open lattice.

Palliative treatment of malignant neoplasms in the biliary tree

no known contraindications

7

Amplatzer Vascular Plug

Self expandable nitinol mesh occlusion device, with screw attachment and marker bands at either side.

Arterial and venous embolizations in the peripheral vasculature

no known contraindications

8

Amplatzer Atrial Septal Occluder

Percutaneous, transcatheter, atrial septal defect closure device intended for the occlusion of atrial septal defects (ASD), made of a Nitinol mesh filled with polyester fabric sewn into place by polyester thread.

- Echocardiographic evidence of ASD;

- Intracardiac thrombus

- Right ventricular volume overload

- Coagulation disorders

- Closure of the fenestration from a prior fenestrated fontan procedure

- Inadequate vessel size,

 

- Thinned septum which will not secure the device

9

Helex Occluder

ePTFE patch material supported by a single nitinol wire frame.

Transcatheter closure of ostium secundum atrial septal defects. Over several months cells being to infiltrate and grow over the ePTFE material for closure of the defect

- Intracardiac thrombi, vasculature which cannot accommodate the introducer sheath,

- If position required is too close to valves

- Patients in whom anticoagulation is contraindicated

10

Flipper Detachable Embolization Coil

Stainless steel wire with synthetic fibers,

Arterial and venous embolization of peripheral vasculature

no known contraindications

11

Nit-Occlud Coil

Nitinol coil designed for patent ductus arteriosus (PDA) It has a stiffer aortic side, and a more flexible pulmonary side for this purpose.

Closure of Patent ductus arteriosus (PDA)

no known contraindications
