Abstract

"DILATADOR-INCISOR COM BALãO AFUNILADO". A presente invenção é um dispositivo para realizar um incisão e um dilatação dos segmentos estenóticos dentro dos sistema vascular de um paciente. Estruturalmente, a presente invenção inclui uma sonda de dilatação elipsoidal rígida montada na extremidade distal de um catéter. Uma série da lâminas orientadas longitudinalmente se projeta radialmente a partir da superfície de sonda. Um balão inflável afunilado também é montado no catéter em uma posição que é proximal à sonda de dilatação. Em uso, a sonda e o catéter são avançados sobre um fio guia para alcançar o segmento estenótico alvo. A sonda e as lâminas são então avançadas através do segmento estenótico para realizar a incisão na estenose. O balão pode então ser inflado a fim de adotar um formato fusiforme afunilado, permitindo que o balão avance através da estenose para dilatar adicionalmente a estenose. Alternativamente, o balão pode ser posicionado através da estenose e inflado para dilatar a estenose. O formato fusiforme do balão corresponde á geometria afunilada de muitos vasos arteriais coronátios, diminuindo as chances de um segmento do vaso ser pressurizado excessivamente pelo balão de enchimento.
