Abstract
A dilator tip assembly of an endoprosthetic delivery device includes a mounting component of an endoprosthetic delivery device, the dilator tip being mountable on a distal end of the mounting component and defining a luminal conduit having a longitudinal axis and a chamfered proximal end, the luminal conduit including a luminal lateral groove. A circlip mountable on the mounting component at the mounting component lateral groove secures the mounting component to the dilator tip by occupying both the mounting component lateral groove of the mounting component and the luminal lateral groove of the dilator tip.

A dilator tip assembly of an endoprosthetic delivery device, comprising:
- a) a mounting component of an endoprosthetic delivery device, the mounting component including a proximal end and a distal end, and defining a mounting component lateral groove between the proximal end and the distal end;
- b) a dilator tip of the endoprosthetic delivery device mountable on the distal end of the mounting component, the dilator tip having a proximal end and a distal end, and defining a luminal conduit having a chamfered proximal end, and wherein the luminal conduit includes a luminal lateral groove between the proximal end and the distal end of the luminal conduit;
- and
- c) a circlip that is mountable on the mounting component at the mounting component lateral groove, wherein longitudinal travel of the circlip, while mounted on the mounting component lateral groove, along the chamfered proximal end toward the luminal conduit causes radial compression of the circlip, whereby the circlip is directed to the luminal lateral groove and expands within the luminal groove, aligning with and engaging the luminal lateral groove, and securing the dilator tip to the mounting component, the dilator tip thereby being mounted on the mounting component.
A method of mounting a dilator tip on a mounting component of an endoprosthetic delivery device, comprising the steps of:
- a) assembling a circlip with a mounting component of an endoprosthetic delivery device at a mounting component lateral groove defined by the mounting component and located between a proximal end and a distal end of the mounting component;
- and
- b) directing the distal end of the mounting component, while assembled with the circlip, into a chamfered proximal end of a luminal conduit of a dilator tip of the endoprosthetic delivery device, whereby the circlip is radially compressed during travel in a distal direction along the chamfered proximal end, further travel of the circlip into the luminal conduit of the dilator causing the circlip to be directed to and radially expand within a luminal groove defined by the luminal conduit, thereby mounting the dilator tip on the mounting component.
