Embodiment 1

[0032] The implant in this embodiment is an implant with at least one cavity, please refer to figure 1 , the implant 100 can be, but not limited to, a lung volume reduction ring. The implant 100 includes a hollow tubular implant base 110 and a hollow tubular connector 120 (please refer to figure 2 As shown in the sectional view), after the implant 100 is implanted in the body, the connecting member 120 is located at the proximal end of the implant 100 . The implant 100 can be cut from a nickel-titanium metal tube with superelasticity and shape memory.

[0033] Please also refer to Figure 3-Figure 5 , the delivery and recovery device 200 for implant 100 (not shown) having at least one cavity includes a delivery assembly 210, a first control assembly 220 and a second control assembly 230 that are sheathed in sequence from outside to inside, and the delivery The component 210 is located at the outermost layer of the delivery and recovery device 200, the second control compon...

Embodiment 2

[0043] Embodiment 2 proposes a delivery and recovery system for an implant 100 with at least one cavity, including the implant 100, and also includes the delivery of the implant 100 with at least one cavity in Embodiment 1 And recovery device 200. With the help of the existing medical equipment bronchoscope, the delivery and recovery system can realize the delivery, release and recovery of the implant 100 . Preferably, the implant 100 is a lung volume reducing implant. The distal end of the delivery and recovery device 200 runs through the distal end of the bronchoscope from the proximal end of the bronchoscope, and the bronchoscope is used to guide the distal end of the delivery and recovery device 200 to the target position in the body, and the delivery and recovery device 200 is used to transfer the hollow tubular The implant body 100 is delivered to the target position in the body for release; or, the distal end of the delivery and recovery device 200 is connected to the ...

Abstract

The invention relates to a delivery and retrieval device for an implant having at least one cavity, comprising a delivery assembly, a first control assembly and a second control assembly, the delivery assembly includes a first cavity and a forceps base, the The first control assembly includes a second cavity and a jaw, the distal end of the first control assembly extends into the first cavity from the proximal end of the delivery assembly, and the distal end of the second control assembly extends from the The proximal end of the first control assembly extends into the second cavity; the forceps base and the jaws cooperate to clamp or loosen the proximal end of the implant, and the second control assembly is used to Straighten the implant when protruding from the jaws and into the lumen of the implant, and release the implant when withdrawn from the lumen of the implant body. The invention also relates to a delivery and retrieval system for an implant having at least one cavity. The device of the present invention does not cause damage to lung tissue when the implant is delivered in vivo.

Description

technical field [0001] The invention relates to the technical field of interventional medicine, in particular to a delivery and recovery device and system for an implant with at least one cavity. Background technique [0002] Emphysema is a common disease, especially in the elderly. According to statistics, the survival rate of patients with end-stage emphysema after 5 years of illness is less than 50%. Traditionally, the medical treatment of emphysema includes oxygen inhalation, prevention of lung infection, bronchial spasm, etc., but the curative effect is extremely limited. Surgical treatment is mostly based on lung volume reduction surgery. The lung volume reduction implant is delivered to the target area of ​​the lungs of the human or animal body using a conveyor and then released, thereby compressing the lung tissue and reducing the lung volume. [0003] Implants placed in the body need to be removed from the body at the appropriate time. The existing implant recove...
