Abstract
Apparatus is provided for facilitating percutaneous delivery of an implant to a target site of a body of a subject. The apparatus includes a delivery tool that includes a needle that defines a lumen through which the implant passes. The needle has a proximal end and a distal end, and defines a triple-grind bevel at the distal end. The triple-grind bevel defines a primary grind and two side-grinds. The side-grinds do not extend to meet each other to define a point at a distal-most part of the needle. Other embodiments are also described.

Apparatus for facilitating percutaneous delivery of an implant to a target site of a body of a subject, the apparatus comprising a delivery tool, the delivery tool comprising a needle, the needle comprising:
- a distal end;
- and
- a proximal end,
- the needle defining:
- a lumen configured to facilitate passage of the implant therethrough,
