Abstract

A coupling device, set to be linked to an interventional delivery system, for coupling and releasing a medical implant. The coupling device comprises a generally tubular channel sized and shaped to be conducted in an intravascular catheter and a pivot extended in and along the generally tubular channel having a distal end comprising a lower surface for applying pushing force a medical implant and an upper surface, mounted above the lower generally tubular surface and having at least one niche for receiving at least one anchoring element of the medical element so that a tip of each the anchoring element is placed between the lower and upper surfaces.

Claims

1. A coupling device, set to be linked to an interventional delivery system, for coupling and releasing a medical implant, comprising:

a generally tubular channel sized and shaped to be conducted in an intravascular catheter; and

a pivot extended in and along said generally tubular channel having a distal end comprising a lower surface for applying pushing force on a medical implant and an upper surface, mounted above said lower generally tubular surface and having at least one niche for receiving at least one anchoring element of said medical element so that a tip of each said anchoring element is placed between said lower and upper surfaces.

2. The coupling device of claim 1, wherein said generally tubular channel is sized and shaped to cover said pivot and said medical implant so as to fasten said at least one anchoring element between said upper and lower generally tubular surfaces.

3. The coupling device of claim 1, wherein said pivot is coated with a polymer to provide a supportive structure.

4. The coupling device of claim 1, wherein said medical implant is coupled to said pivot without and direct mechanical connection.

5. The coupling device of claim 1, wherein said pivot is mechanically connected to a control mechanism facilitating the retrieving or repositioning of said medical implant into said generally tubular channel.

6. The coupling device of claim 1, wherein said pivot is mechanically connected to a safety mechanism for requiring a verification action of the user before a deployment of said medical implant.

7. The coupling device of claim 1, wherein said distal end is curved so that said tip is directed substantially toward said upper surface when respective said anchoring element being placed between said lower and upper surfaces.

8. A method for coupling a medical implant, the method comprising:

providing a coupling device comprising a generally tubular channel sized and shaped to be conducted in an intravascular catheter and a pivot extended in and along said generally tubular channel having a distal end comprising substantially parallel lower and upper surfaces having a gap therebetween, said upper surface having at least one niche;

placing at least one anchoring element of a medical implant in proximity to said distal end so that at least a tip of said at least one anchoring element implant is placed between said lower and upper surfaces and so that said at least one anchoring element passing through said upper surface; and

encircling said medical implant using said generally tubular channel.

9. The method of claim 8, wherein said medical implant having an elastic blocking element having compressed and uncompressed states, said encircling comprising covering said elastic blocking element in said compressed state.

10. The method of claim 9, further comprising uncovering said at least one anchoring element so as to allow outward tilting thereof.

11. The method of claim 9, wherein said medical implant is discoupled by:

uncovering said at least one anchoring element, and

rotating said pivot in relation to said generally tubular channel.

12. The method of claim 9, wherein said placing comprises:

attaching an implant adaptor containing said medical implant in front of distal end of said generally tubular channel,

performing said placing, and

pulling said pivot into said generally tubular channel.

13. A coupling device, set to be linked to an interventional delivery system, for coupling and releasing a medical implant, comprising:

a generally tubular channel sized and shaped to be conducted in an intravascular catheter; and

a pivot extended in and along said generally tubular channel having a distal end comprising a fastening element for coupling with a complementary fastening element of a medical implant.

14. The coupling device of claim 13, wherein said pivot, said fastening element, and said complementary fastening element have a common diameter.
