Extractable filler for inserting medicine into animal tissue

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 permeable 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.

1 . An extractable device for inserting a solidifiable medicinal filling into an animal tissue, comprising:
 a flexible, permeable container having a proximal injection port for injection of the filling into the container, and a releasably closable distal opening for delivery of the filling into the animal tissue outside of the container; and   at least one releasable thread that releasably closes the distal opening to contain the filling within the container prior to solidification, and that reopens the distal opening to enable the delivery of the filling into the animal tissue outside of the container after solidification.   
     
     
         2 . The device of  claim 1 , in which the thread is releasable upon application of an external pulling force. 
     
     
         3 . The device of  claim 1 , in which the thread is releasable upon application of an external pushing force. 
     
     
         4 . The device of  claim 1 , in which the container is sufficiently flexible for removal from the animal tissue after solidification of the filling within the container. 
     
     
         5 . The device of  claim 1 , in which the container is shaped like a bag. 
     
     
         6 . The device of  claim 1 , in which the container is shaped like a ball. 
     
     
         7 . The device of  claim 1 , in which the container comprises a tubular wall. 
     
     
         8 . The device of  claim 1 , in which the container comprises a holding portion integrally formed by a wall of the flexible and permeable container. 
     
     
         9 . The device of  claim 1 , in which the container comprises a single-layered wall. 
     
     
         10 . The device of  claim 1 , in which the container comprises a multi-layered wall. 
     
     
         11 . The device of  claim 1 , in which the container comprises inner and outer layers. 
     
     
         12 . The device of  claim 1 , further comprising means for injecting the solidifiable medicinal filling into the device through the injection port. 
     
     
         13 . The device of  claim 1 , in which the permeable container is formed of a plurality of threads. 
     
     
         14 . The device of  claim 1 , in which the permeable container is formed of a plurality of threads by weaving. 
     
     
         15 . In combination, the device of  claim 1  and an injection tool for injecting the solidifiable medicinal filling into the device through the injection port. 
     
     
         16 . The combination of  claim 13 , in which the injection tool comprises a guide tube connected to the injection port. 
     
     
         17 . A method for implanting a solidified medicine into an animal tissue, comprising:
 inserting into the animal tissue a flexible, permeable container having a distal opening that is releasably closable;   at least partially filling the container with a solidifiable medicinal filling;   solidifying the medicinal filling within the container;   reopening the distal opening of the container; and   depositing the filling into the animal tissue through the distal opening by extracting the container from the animal tissue.   
     
     
         18 . The method of  claim 17 , further comprising injecting the filling into the container through an injection port on a proximal end of the container. 
     
     
         19 . An extractable device for placing a solidifiable medicinal filling into an animal tissue, comprising:
 a flexible, permeable container, comprising a proximal inlet for receipt of the filling and a releasably closable distal outlet for subsequent delivery of solidified filling into the animal tissue;   at least one releasable thread to reduce leakage of the filling from the container.   
     
     
         20 . A method for placing a solidified medicine into an animal tissue, comprising:
 inserting into the animal tissue a flexible, permeable container having a proximal inlet and a distal, releasably leakproof outlet;   providing the container with a solidifiable medicinal filling through the proximal inlet;   solidifying the filling within the container;   reopening the distal outlet;   delivering the solidified filling into the animal tissue through the distal outlet opening; and   removing the container from the animal tissue.
