Title
(EN) IMPROVED HEMOSTATIC MATERIAL AND DEVICE FOR ACHIEVING DURABLE HEMOSTASIS OF A BLEEDING BIOPSY TRACT
(FR) MATÉRIAU HÉMOSTATIQUE AMÉLIORÉ ET DISPOSITIF PERMETTANT D'OBTENIR UNE HÉMOSTASE DURABLE D'UNE VOIE HÉMORRAGIQUE DE BIOPSIE
Abstract
(EN) Systems and method of facilitating hemostasis in a tract in a patient are disclosed. The method can include, in some cases, delivering an elongate member into the tract, the elongate member comprising a lumen; injecting a suspension through the elongate member, the suspension comprising pledgets comprising surface irregularities; a hemostatic agent; and particles comprising an average diameter less than an average diameter of the pledgets. The pledgets, hemostatic agent, and particles pack the tract and promote hemostasis.
(FR) Sont divulgués des systèmes et un procédé permettant de faciliter l'hémostase d’une voie chez un patient. Le procédé peut comprendre, dans certains cas, l'administration d'un élément allongé dans la voie, l'élément allongé comprenant une lumière ; l'injection d'une suspension dans l'élément allongé, la suspension comprenant des petites compresses comprenant des irrégularités de surface ; un agent hémostatique ; et des particules comprenant un diamètre moyen inférieur à un diamètre moyen des petites compresses. Les petites compresses, l'agent hémostatique et les particules remplissent la voie et favorisent l'hémostase.
