Braided medical device and manufacturing method thereof
An medical implantable occlusion device ( 100 ) is disclosed having a collapsed state and an expanded state and comprising a braiding ( 101 ) of at least one thread, and a distal end ( 102 ) comprised of said braiding. The distal end comprises loops ( 103, 104, 204, 304 ) formed by loop strands ( 105, 106, 206, 306 ) of the at least one thread, wherein, at least in said expanded state, each loop strand has a curved shape and extends away from a centre point ( 117 ) of the distal end, whereby an apex point ( 107, 108, 208, 308 ) of each of the loop strands corresponds to the turning point of the curved shape and to the point of each of the loop strands being arranged closest to the centre point. At least one of the loop strands is displaced from the centre point by a centre distance ( 109, 110, 210, 310 ), and the apex point lie at a distance from a periphery ( 113 ) of the distal end.
1. A medical implantable occlusion device comprising:
a braiding of at least one thread, and
a distal end having a periphery and a center,
a proximal end comprising a fixation,
wherein said distal end comprising loops formed by loop strands,
wherein each loop strand has a curved shape with an apex located between said periphery of said distal end and said center of said distal end,
wherein said occlusion device comprises a through going hole between said distal and proximal end through said device.
2. The medical implantable device according to claim 1 , wherein said through going hole between said distal and proximal end through said device forms a center axis between said proximal and distal end.
3. The medical implantable device according to claim 1 , wherein said distal end has a circular disc shape, and or a spherical shape, and/or an elongate shape.
4. The medical implantable device according to claim 1 , wherein said loop strands are formed such that the strands cross each other.
5. The medical implantable occlusion device according to claim 1 , comprising at least two groups of loop strands forming said distal end,
wherein the apices of said first group of loop strands are located about a first radius from said center, and
wherein the apices of said second group of loop strands are located about a second radius from said center.
6. The medical implantable occlusion device according to claim 1 further comprising at least one center strand, wherein said at least one center strand crosses said distal end at a region close to said center of said distal end but are not crossing said center.
7. The medical implantable occlusion device according to claim 1 , wherein the medical implantable occlusion device is an atrial septal defect (ASD) occlusion device.
8. The medical implantable occlusion device according to claim 1 , wherein the medical implantable occlusion device is a ventricular septal defect (VSD) occlusion device.
9. The medical implantable occlusion device according to claim 1 , wherein the medical implantable occlusion device is an arterial venous fistula (AVF) occlusion device.
10. The medical implantable occlusion device according to claim 1 , wherein the medical implantable occlusion device is a patent foramen ovale (PFO) occlusion device.
11. The medical implantable occlusion device according to claim 1 , wherein the medical implantable occlusion device is a para-valvular leak (PVL) occlusion device.
12. The medical implantable occlusion device according to claim 1 , wherein the medical implantable occlusion device is an atrial venous malformation (AVM) occlusion device.
