Abstract
The present invention relates to a heart valve prosthesis loading device and a method for loading a heart valve prosthesis onto a delivery system.
Claims12
An assembly of parts for crimping and/or loading a stent or stent-based prosthesis onto a delivery device or for converting a stent or stent-based prosthesis from an expanded diameter to a compressed diameter, comprising:
- (a) a funnel;
- (b) rotatable wheel;
- (c) at least one pulling suture releasably attached or deconnectable to the stent or stent-based prosthesis;
- (d) at least one pulling suture guidance hole for passing the at least one pulling suture through;
- (e) a tubular structure having an opening in an axial direction within a base part, wherein the base part is free of a through-hole in the axial direction;
- and
- (f) a peel-off tube capable of holding a portion of the stent-based prosthesis in a crimped state, wherein an outer diameter of the peel-off tube is smaller than an inner diameter of an outer shaft of a catheter, wherein the peel-off tube is configured to be split longitudinally and separated from the stent or stent-based prosthesis by pulling during loading into the catheter;
- wherein the stent or stent-based prosthesis comprises a non-smooth surface.
