Abstract
A device is designed to anchor a tissue to a bone. The device comprises a contractible implant, one or more sutures attached to the implant, and a pasty medicine capable of solidification. The implant is made of a flexible wall and provided with a holding portion and an injection port. The flexible wall is provided with a plurality of pores, each having a diameter smaller than 0.1 millimeter. The pasty medicine is injected into the holding portion of the implant upon completion of insertion of the contracted implant into the bone, thereby resulting in expansion of the contracted implant. The implant is thus securely lodged in the bone upon solidification of the pasty medicine to facilitate the anchoring of the tissue to the bone by suturing.
Claims15
A method for anchoring a tissue to a bone, said method comprising the following steps:
- inserting an implant into a bone, said implant made of a flexible wall and provided with a holding portion and an injection port in communication with said holding portion, with said holding portion being enclosed by said flexible wall which is provided with a plurality of pores, each having a diameter smaller than 0.1 mm, wherein said implant is contractible and is contracted prior to being inserted into the bone, wherein said implant is provided with one or more sutures, said sutures are fastened at one end with said implant, such that other end of the sutures is extended out of the bone;
- injecting a pasty medicine capable of solidification into said holding portion via said injection port of said implant in the wake of insertion of said implant into the bone, thereby resulting in expansion of said implant so as to enable said implant to be securely lodged in the bone upon completion of the solidification of said pasty medicine;
- and
- fastening the other end of one or more sutures with a tissue.
