Implant, medical implant, and method for delivery of a medical implant
An intravascular delivery device is disclosed comprising a delivery wire having a proximal and a distal end and an interior lumen extending there between and wherein said distal end comprises a connection interface adapted to matingly interlock with a proximal end portion of a medical implantable device, wherein said delivery device comprises a locking unit arranged to secure said connection interface in a locking position in which said medical implant is pivotably locked before a controlled release.
1. An intravascular delivery device comprising:
a delivery wire having a proximal end and a distal end; and,
an interior lumen extending therebetween; and,
wherein said distal end comprises a connection interface adapted to matingly interlock with a proximal end portion of a medical implantable device;
a locking unit arranged to secure the connection interface in a locking position in which the medical implantable device is pivotably locked before a controlled release;
a locking wire arranged moveably within the lumen of the delivery wire for relative longitudinal movement therein, the locking wire having a distal end comprising a holding structure, and;
wherein the holding structure comprises two longitudinal extensions being resiliently radially outwardly expandable at their distal ends and wherein the two longitudinal extensions are integrally connected as one piece.
2. The intravascular delivery device according to claim 1 whereby said holding structure is axially moveable relative to said delivery wire between said locking position at which said delivery wire encloses said holding structure and a second position at which said holding structure at least partly protrudes beyond said distal end of said delivery wire such that said connection interface unlocks and said medical implantable device is controllably released.
3. The intravascular delivery device according to claim 1 , wherein said medical implantable device is an occlusion device for occluding a selected site in a body.
4. The intravascular delivery device according to claim 1 , wherein said connection interface holding said medical implantable device provides for an axial flexibility such that said medical implantable device may tilt relative the longitudinal axis of said delivery device.
5. The intravascular delivery device according to claim 1 wherein said holding structure is radially enlarged to at least partly contact the interior lumen of said distal end of said delivery wire.
6. The intravascular delivery device according to claim 1 wherein each of the longitudinal extensions of said holding structure having a recess for receiving a portion of said medical implantable device.
7. The intravascular delivery device according to claim 6 , wherein said recesses of the two longitudinal extensions are in the form of a portion of a sphere configured to enclose said proximal end portion of said medical implantable device at least partly.
8. The intravascular delivery device according to claim 1 comprising a control device connected to said proximal end of said delivery wire for controllably unlocking of said connection interface.
9. The intravascular delivery device according to claim 8 , wherein said control device is secured when said holding structure is in said locking position such that said control device has to be manually operated to allow for said unlocking of said connection interface for controlled release of said medical implantable device from said delivery device.
10. An assembly comprising:
a delivery device according to claim 1 and
a medical implantable device arranged in a catheter for intravascular delivery of said medical implantable device.
11. The intravascular delivery device according to claim 1 , comprising a resiliently flexible unit arranged to provide for flexibility of the intravascular delivery device in said locking position.
12. The intravascular delivery device according to according to claim 1 , wherein said medical implantable device is an occlusion device for occluding a selected site in a body.
13. In combination, the intravascular delivery device of claim 1 , and the medical implantable device with the proximal end portion of the medical implantable device releasably interlocked with said connection interface.
14. The combination of claim 13 , wherein said medical implantable device comprises a bundle of strands, said bundle of strands of said device comprising a welded end having a welded proximal end portion, wherein said welded proximal end portion has defined proportions and dimensions configured as a connection interface adapted to matingly interlock with the holding structure.
15. The combination of claim 13 , arranged in a catheter for intravascular delivery of said medical implantable device.
