Fistula treatment devices and methods

Disclosed herein are implantable fistula treatment devices and related methods. In some embodiments, an anorectal fistula treatment device may comprise a disc-shaped distal anchor comprising a concave side and a convex side, an outer edge region, an inner sealing region protruding from the concave side, and an attachment region configured for attachment to a connecting member. The inner sealing region may have a greater thickness than at least a portion of the attachment region and the outer edge region may be oriented at an acute angle to the inner sealing region. The distal anchor may have a tapered edge and the outer edge region and inner sealing region may be configured to form separate seals against tissue about a distal opening of an anorectal fistula. 本发明公开了可植入式瘘治疗装置及相关方法。在些实施例中，个肛门直肠瘘治疗装置可包括凹面和凸面组成的盘形远端锚定件、外缘区、从凹面突出的内部密封区以及用于附接连接部件的附接区。内部密封区可能至少比附接区的部分厚，且外缘区可以被调整到与内部密封区成锐角。远端锚定件可能具有锥形边，外缘区和内部密封区可以配置形成单独密封用以抵靠肛门直肠瘘远端开口的组织。
