Title
(EN) APPARATUS AND METHODS OF USE FOR PREVENTING BLOOD SEEPAGE AT A PERCUTANEOUS PUNCTURE SITE
(FR) APPAREIL ET PROCEDES DESTINES A LA PREVENTION DU SUINTEMENT DE SANG AU NIVEAU D'UN SITE DE PONCTION PERCUTANEE
Abstract
(EN)
Apparatus (20, 100, 200) and methods of use for reducing bleeding from the situs of a percutaneous arterial puncture (10) in a living being, with the opening (10B) in the arterial wall having been closed by a closure (24, 208) including at least one portion of a suture (24A, 24B, 208) extending out of the puncture. The apparatus basically comprising a mass of material (22, 212) which inhibits the flow of blood therethrough, e.g., collagen, a carrier (30, 206, 210) for carrying the suture portion through the mass of material, and means (24E, 46, 50, 250, 252) for holding the mass of material with respect to the suture portion so that it closely engages tissue contiguous with the puncture tract. The means for holding may comprise a knot (24E, 252) in the suture portion, or can be a releasably securable member (46, 50, 250) for location on the suture portion. In one embodiment, the carrier comprises a piercing member, e.g., a needle (206), arranged for location within the interior of the artery for passage thereout through the wall of the artery and through the mass of material to carry the suture portion therethrough. In another embodiment, the carrier comprises an elongated member, e.g., a flexible filament (44), arranged to selectively grasp the suture portion to carry it through the mass of material. A housing (26) is provided for retaining the mass of material while the carrier extends the suture portion through it. A tamper (28) may be provided for tamping the mass of material into intimate engagement with the contiguous tissue.

L'invention se rapporte à un appareil (20, 100, 200) et à des procédés d'utilisation de ce dernier, qui permettent de réduire le saignement provenant d'un site de ponction artérielle percutanée (10) effectuée sur un être humain, l'ouverture (10B) de la paroi artérielle ayant été fermée par un élément de fermeture (24, 208) comprenant au moins une partie d'un fil de suture (24A, 24B, 208) s'étendant à l'extérieur de la ponction. L'appareil comprend essentiellement une masse de matière (22, 212), tel que du collagène, qui empêche le sang de passer, un support (30, 206, 210) faisant passer la partie du fil de suture dans la masse de matière, et un élément (24E, 46, 50, 250, 252) retenant la masse de matière par rapport à la partie du fil de suture de sorte qu'il place le tissu contigu en contact étroit avec la voie de ponction. Cet élément de retenue peut comporter un noeud (24E, 252) dans la partie du fil de suture ou peut être un élément de fixation libérable (46, 50, 250) se plaçant sur la partie du fil de suture. Selon un mode de réalisation, le support comprend un élément de perçage, tel qu'une aiguille (206), conçu pour se placer à l'intérieur de l'artère et traverser la paroi de l'artère ainsi que la masse de matière afin de transporter la partie du fil de suture à travers cette dernière. Selon un autre mode de réalisation, le support comprend un élément allongé, tel qu'un filament souple (44), permettant de saisir sélectivement la partie du fil de suture pour la transporter à travers la masse de matière. Un corps (26) sert à retenir la masse de matière tandis que le support fait passer la partie du fil de suture dans la masse. Un élément de tassement (28) peut être prévu pour tasser la masse de matière et la placer en contact étroit avec le tissu contigu.
