Device number | Device name | 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 |
