Alternatively, a push-out catheter is known to push out the main body from the tip of the catheter, and the main body has a badminton shuttle shape and a pawl for preventing movement is provided on the outside of the shuttle. (For example, Japanese Medical Journal 51st 7th
No. 72P to 74P) As another technique, as shown in FIG. 22, a net-shaped fiber (5) for catching a bird is fixed to one end of two V-shaped filter shafts (4) to form a V-shaped filter shaft (4). There is known a technique in which a pawl (6) for preventing movement is provided in the portion (4) and is placed in a blood vessel. (For example, JouNAL of

【発明が解決しようとする課題】従来の技術には，次の
ような欠点があった。 イ）形状がシャトル状であるため血管内で固定しにく
く，患者の体位により簡単に傾き血栓を通しやすい。 ロ）体内に挿入時大径のカテーテルを用いてフィルター
を挿入するため血管損傷が大きい。 ハ）フィルター本体が溶接により組み立ててあるため，
長期に挿入中，本体が折れやすい。The prior art has the following drawbacks. B) Due to its shuttle-like shape, it is difficult to fix it inside the blood vessel, and it is easy to tilt the blood clot depending on the patient's position. B) When inserted into the body, a large-diameter catheter is used to insert the filter, resulting in large blood vessel damage. C) Since the filter body is assembled by welding,
The body easily breaks during long-term insertion.

熟練者でないとネットの留置形状にムラができる。 本発明は以上の欠点をなくすために発明されたものであ
る。With regard to the latter technique, d) it is time-consuming and complicated because it is a method of pushing out a filter from the tip of a catheter to form a net shape in a blood vessel. E) Once inserted and placed in the blood vessel, the recovery position cannot be corrected because there is no recovery or correction ring and no metal thread. F) Since the net is created by operating the guide wire, the indwelling shape of the net can be uneven unless the user is skilled. The present invention has been invented to eliminate the above drawbacks.

It can be used even if you are not a person. (B) Since the filter is in a state of capturing the thrombus simply by pushing it out of the sheath, the operation can be completed in a short time. C) Since both ends of the filter are always in contact with the blood vessel wall, stability is good and it does not easily collapse and move. D) Since the filter has a structure that does not easily fall, thrombus does not pass through due to the filter falling. E) Since a collection part can be made in the filter,
Can be collected and moved.
