摘要:
"barbed sutures having contour barbs that facilitate passage through the fabric and increase retention resistance". wound closure device (200) includes a filamentous member (202) having a proximal end (206) and a distal end (210), and a plurality of barbs (204) extending outwardly from the filamentous member. each barb has a base (230) connected to the filamentous member, a tip (232) spaced from the base, and an outer edge (234) extending between the base and the tip. the outer edge includes a first section (242) having a concave surface extending between the base and a barb transition point (246) and a second section (244) having a convex surface extending between the transition point of the barb and the tip of the barb. the outer edge transforms from the concave surface of the first section to the convex curve of the second section at the barb transition point. the barb tip has a convexly curved surface facing the distal end of the filamentous member. The unique dual radius shape of the outer edge of the barbs minimizes resistance when the filamentous element is pulled in a first direction through the fabric and maximizes movement resistance when the filamentous element is pulled in an opposite second direction through the fabric to keep the wound closure device in steady state.resumo patente de invenção "suturas farpadas tendo farpas de contorno que facilitam a passagem através do tecido e aumentam a resistência de retenção". dispositivo para fechamento de ferimento (200) inclui um elemento filamentoso (202) tendo uma extremidade proximal (206) e uma extremidade distal (210), e uma pluralidade de farpas (204) estendendo-se para fora a partir do elemento filamentoso. cada farpa tem uma base (230) conectada com o elemento filamentoso, uma ponta (232) espaçada em relação à base, e uma borda externa (234) estendendo-se entre a base e a ponta. a borda externa inclui uma primeira seção (242) tendo uma superfície côncava que estende-se entre a base e um ponto de transiç
