Matrix detachable coils (Boston Scientific Neurovascular) are another example of modified endovascular coils, employing a stainless steel delivery wire coated with a bioabsorbable copolymer of 90% polyglycolide and 10% polylactide. In a study by Murayama et al. (2003), matrix detachable coils were shown to accelerate the rate of aneurysm healing in swine aneurysm models, specifically by promoting the formation of a thick neointimal layer at the aneurysm neck more quickly bare platinum coils (Murayama et al, 2003). Taschner et al. (2005) evaluated the use of Matrix detachable coils in 25 patients with intracranial aneurysms. Again, stable emboUzed aneurysms were achieved over a six-month period, but only when Matrix coils were used in conjunction with bare platinum coils (Taschner et al, 2005).

Future perspectives Detachable coils can be repositioned until a focal and compact mechanical obstruction is achieved. Detachable coils may be covered with small Dacron strands to promote thrombus formation or with an expanding hydrogel to minimize dead space between the coil loops. Although dedicated detachable coils are available for intracranial aneurysm embolization, the high cost of these coils precludes its routine use in non-neurointerventional indications.
