Medical implant attachment mechanism

A system comprising:

• an elongate shaft including a wall defining a lumen;
• a medical implant including a wall defining a lumen;
• a first attachment part configured to be fixedly attached to a distal end of the elongate shaft, the first attachment part having a tubular proximal portion with a first engagement feature configured to non-reversibly engage the elongate shaft, such that when the tubular proximal portion and the first engagement feature are inserted within the lumen of the elongate shaft, the first engagement feature fixedly attaches the first attachment part to the elongate shaft;
• and
• a second attachment part configured to be fixedly attached to a proximal end of the medical implant, the second attachment part having a tubular distal portion with a second engagement feature configured to non-reversibly engage the medical implant, thereby fixedly attaching the second attachment part to the medical implant;
• wherein the first attachment part and the second attachment part are configured to interlock with each other such that relative axial translation between the first attachment part and the second attachment part is prevented when the first attachment part is interlocked with the second attachment part;
• wherein the tubular distal portion and the second engagement feature are configured to be inserted within the lumen of the medical implant, such that when the tubular distal portion and the second engagement feature are inserted within the lumen of the medical implant, the second engagement feature fixedly attaches the second attachment part to the medical implant.
