SYSTEM AND METHOD FOR LOADING A STENT INTO A MEDICAL DELIVERY SYSTEM

摘要

The present disclosure relates to a device (100) for compressing and releasably connecting a stent (50), in particular the self-expanding stent (50) having a replacement placement heart valve (60) affixed thereto, with retaining means (70) of a delivery catheter system, in particular with retaining means (70) provided in or at a catheter tip (80, 80-1, 80-2) of a delivery catheter system. The loading system (100) comprises fixing means (10) for releasable fixing the stent (50) and centering means (30) connectable to the fixing means (10) for centering the stent (50) fixed to the fixing means (10). The fixing means (10) comprises a cup-shaped element (11) having a rim zone (12) formed inside the cup-shaped element (11) for clamping the stent (50). The centering means (30) comprises a frustoconical housing (31) having an open end (31.2) opposite to the fixing means (10). The housing (31) is configured to compress the stent (50) when the stent (50) is moved through the housing (31).

主权项

1. A system for loading a stent into a catheter wherein the system comprises:
a first component for receiving a first portion of the stent; and a second component for receiving a second portion of the stent, the second component being connectable to the first component; wherein the first component comprises a cup-shaped element including a rim zone, the cup-shaped element having a longitudinal axis; wherein the rim zone includes a side surface extending substantially parallel to the longitudinal axis of the cup-shaped element for receiving the first portion of the stent within the cup-shaped element; and wherein the second component comprises a housing having an open end, the open end being opposite to the first component when the second component is connected to the first component, wherein the housing includes a frustoconical area configured to compress the stent when the stent is moved through the housing.
