Publication number: 20230233347Abstract: The invention relates to an insertion system for an implant (1) for influencing the blood flow in the region of aneurysms (22) located at vascular bifurcations. The implant (1) has two distal tubular implant portions (2) which are intended to be placed in blood vessels (21) branching off from the stem blood vessel (20) and which are connected to one another at a branching point (4). The insertion system has two sleeves (5) which are each designed to hold a distal tubular implant portion (2). The two sleeves (5) each have a distal sleeve portion (6) and the distal sleeve portions (6) each have an opening zone (7) extending in the longitudinal direction. The distal sleeve portions (6) are each adjoined proximally by a proximal portion (8), by means of which the sleeves (5) can be retracted in the proximal direction so that the opening zones (7) open and the distal tubular implant portions (2) each pass through the opening zones (7) and are released into the branching blood vessels (21).Type: ApplicationFiled: June 14, 2021Publication date: July 27, 2023Applicant: phenox GmbHInventors: Hans HENKES, Hermann MONSTADT, Ralf HANNES, Volker TRÖSKEN, Stefan ROLLA

Patent number: 10265154Abstract: A blood vessel implant to influence the flow of blood in the area of arteriovenous malformations. The implant has a wall of individual filaments forming a tubular braiding extending axially from the proximal to the distal end, the individual filaments crossing and forming points of intersection. The implant is deformable so that in an insertion catheter it is shaped so that its diameter is reduced and can be expanded at the implantation site adapting to the diameter of the blood vessel. The filament ends at the proximal and/or distal end of the braiding are each brought together at least in pairs and connected with each other permanently. The filament ends connect with each other and are shaped so as to be atraumatic The filaments cross at the points of intersection distally from the filament ends and are connected with each other at the proximal end of the implant.Type: GrantFiled: September 7, 2011Date of Patent: April 23, 2019Assignee: Phenox, GmbHInventors: Manuel Schneider, Stefan Rolla, Carsten Aporta, Ralf Hannes, Hermann Monstadt
