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 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.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
166 words
An extractable device, comprising: a flexible, permeable container having a proximal injection port configured to receive a solidifiable medicinal filling, and a previously created releasably closable distal opening configured to selectively allow delivery of the filling into a human tissue through an incision in the human tissue; and at least one releasable thread configured to releasably close the distal opening to contain the filling within the container prior to solidification, and configured to allow the distal opening to reopen without permanently severing the container to enable the delivery of the filling into the human tissue through the incision after at least partial solidification, the container having a first configuration and a second configuration, when the container is in the second configuration, the distal opening of the container is open and the container is disposed at least partially within the human tissue during a surgical procedure, the proximal injection port having a substantially constant size when the container is in the first configuration and the second configuration.
Claim 2
Dependent Claim
166 words
An extractable device, comprising: a flexible, permeable container having a proximal injection port configured to receive a solidifiable medicinal filling, and a previously created releasably closable distal opening configured to selectively allow delivery of the filling into a human tissue through an incision in the human tissue; and at least one releasable thread configured to releasably close the distal opening to contain the filling within the container prior to solidification, and configured to allow the distal opening to reopen without permanently severing the container to enable the delivery of the filling into the human tissue through the incision after at least partial solidification, the container having a first configuration and a second configuration, when the container is in the second configuration, the distal opening of the container is open and the container is disposed at least partially within the human tissue during a surgical procedure, the proximal injection port having a substantially constant size when the container is in the first configuration and the second configuration.
Claim 3
Dependent Claim
28 words
The device of claim 1 , in which the thread is releasable upon application of at least one of an external pulling force or an external pushing force.
Claim 4
Dependent Claim
27 words
The device of claim 1 , in which the container is sufficiently flexible for removal from the human tissue after solidification of the filling within the container.
Claim 5
Dependent Claim
15 words
The device of claim 1 , in which the container is shaped like a bag.
Claim 6
Dependent Claim
15 words
The device of claim 1 , in which the container is shaped like a ball.
Claim 7
Dependent Claim
14 words
The device of claim 1 , in which the container comprises a tubular wall.
Claim 8
Dependent Claim
22 words
The device of claim 1 , in which the container comprises a holding portion integrally formed by a wall of the container.
Claim 9
Dependent Claim
14 words
The device of claim 1 , in which the container comprises a single-layered wall.
Claim 10
Dependent Claim
14 words
The device of claim 1 , in which the container comprises a multi-layered wall.
Claim 11
Dependent Claim
18 words
The device of claim 1 , in which the container comprises an inner layer and an outer layer.
Claim 12
Dependent Claim

Claim 13
Dependent Claim
19 words
The device of claim 1 , in which the container is formed of a plurality of threads by weaving.
Claim 14
Dependent Claim
25 words
The device of claim 1 , further comprising: an injection tool for injecting the solidifiable medicinal filling into the device through the proximal injection port.
Claim 15
Dependent Claim
21 words

Claim 16
Dependent Claim
49 words
The device of claim 1 , in which the at least one releasable thread has a length such that the at least one releasable thread extends from a location within the human tissue to a location outside of the human tissue when the container is in the second configuration.
Claim 17
Dependent Claim
129 words
An extractable device, comprising: a flexible, permeable container having a proximal inlet configured to receive a solidifiable medicinal filling and a previously created releasably closable distal outlet configured to allow subsequent delivery of solidified filling into a human tissue through an incision in the human tissue without permanently severing the container; and at least one releasable thread configured to reduce leakage of the filling from the container, the container having a first configuration and a second configuration, when the container is in the second configuration, the distal outlet of the container is open and the container is disposed at least partially within the human tissue during a surgical procedure, the proximal inlet having a substantially constant size when the container is in the first configuration and the second configuration.
Claim 18
Dependent Claim
129 words
An extractable device, comprising: a flexible, permeable container having a proximal inlet configured to receive a solidifiable medicinal filling and a previously created releasably closable distal outlet configured to allow subsequent delivery of solidified filling into a human tissue through an incision in the human tissue without permanently severing the container; and at least one releasable thread configured to reduce leakage of the filling from the container, the container having a first configuration and a second configuration, when the container is in the second configuration, the distal outlet of the container is open and the container is disposed at least partially within the human tissue during a surgical procedure, the proximal inlet having a substantially constant size when the container is in the first configuration and the second configuration.
Claim 19
Dependent Claim
49 words
The device of claim 16 , in which the at least one releasable thread has a length such that the at least one releasable thread extends from a location within the human tissue to a location outside of the human tissue when the container is in the second configuration.
