Title: DELIVERY SYSTEM FOR LEFT AURICLE OCCLUDER
Abstract:
A delivery system (100) for a left auricle occluder. A delivery sheath (10) comprises: a main part (11), and a molded part (12) connected to the distal end of the main part (11). The molded part (12) comprises: a first molded section (121), and a second molded section (122) connected to the distal end of the first molded section (121). At least two development units (70a, 70b) are provided at the second molded section (122) and the distance between the at least two development units (70a, 70b) in an axial direction of the second molded section (122) ranges from 10 mm to 40 mm. The delivery system (100) uses the distance between the two development units (70a, 70b) as a reference to measure and calculate the size of a left auricle opening, thereby improving measurement accuracy effectively and reducing the possibility of selecting an unsuitable left auricle occluder model. The delivery system also shortens the measurement time, reduces surgery time and costs, and reduces surgical risks.
