Abstract
Abstract An extractable device is used to insert a medicinal filling into an animal tissue. The device comprises a filling member and a pasty medicine. The filling member is made of a flexible and hermetic wall and is provided with a holding portion and an injection port via which the pasty medicine is injected into the holding portion after the filling member is inserted into the animal tissue. The holding portion is provided with an opening which is releasably lashed by one end of one or more threads so as to make the opening leakproof. Upon completion of solidification of the pasty medicine in the holding portion of the filling member, other end of the thread is pulled to unlash the opening of the holding portion, thereby enabling the filling member to be extracted from the animal tissue so as to leave only the medicine in the animal tissue.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
174 words
An extractable device for inserting a medicinal filling into an animal tissue, said device comprising: a filling member comprising a flexible and hermetic wall and provided with a holding portion, an injection port at one end of the holding portion, and an opening at another, releasably closable, opening end of the holding portion; one or more thread, each having one end for releasably closing said opening end of said holding portion in such a manner that said opening end is leakproof; and a pasty medicine to be injected into said holding portion via said injection port of said filling member in the wake of a process for inserting said filling member into the animal tissue whereby said pasty medicine solidifies in said holding portion of said filling member; said opening of said holding portion being reopened at the time when other end of said threads is pulled by an external force, thereby enabling said filling member to be extracted from the animal tissue so as to leave only said medicine in the animal tissue.
Claim 2
Dependent Claim
174 words
An extractable device for inserting a medicinal filling into an animal tissue, said device comprising: a filling member comprising a flexible and hermetic wall and provided with a holding portion, an injection port at one end of the holding portion, and an opening at another, releasably closable, opening end of the holding portion; one or more thread, each having one end for releasably closing said opening end of said holding portion in such a manner that said opening end is leakproof; and a pasty medicine to be injected into said holding portion via said injection port of said filling member in the wake of a process for inserting said filling member into the animal tissue whereby said pasty medicine solidifies in said holding portion of said filling member; said opening of said holding portion being reopened at the time when other end of said threads is pulled by an external force, thereby enabling said filling member to be extracted from the animal tissue so as to leave only said medicine in the animal tissue.
