摘要:
Disclosed are a lung volume reduction elastic implant and a lung volume reduction device, wherein the lung volume reduction elastic implant (500) is tubular and at least opens at the proximal end thereof, and comprises an elastic deformation section (51), a flexible guide section (53) connected to the distal end of the elastic deformation section (51), and a protuberance (571) connected to the proximal end of the elastic deformation section (51), wherein the elastic deformation section (51) has shape memory characteristics and has several grooves (514) arranged at intervals along the length direction, each groove (514) connecting with the lumen of the elastic deformation section (51). Under the same external force, the flexible guide section (53) deforms more easily than the elastic deformation section (51), the outer diameter of the protuberance (571) is larger than the outer diameter of the elastic implant (500) in the delivery state when same is close to the protuberance (571), and the device delivers the implant without a delivery sheath, thereby preventing the delivery sheath from causing damage to the inner wall of the bronchus and reducing the incidence of pneumothorax.
