Abstract

Abstract An extractable device is used to insert a medicinal filling into a vertebral body. 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 vertebral body. 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 vertebral body so as to leave only the medicine in the vertebral body.

Claims Analysis

Total Claims: 24
Claim 1
Independent Claim 123 words
1 . An extractable device for inserting a solidifiable medicinal filling into an animal tissue, comprising: a flexible 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 releasibly 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; in which the container is inflatable and, after being inflated, is substantially tubular with cross sectional areas that increase from the injection port to the distal opening.
Claim 2
Dependent Claim 123 words
1 . An extractable device for inserting a solidifiable medicinal filling into an animal tissue, comprising: a flexible 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 releasibly 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; in which the container is inflatable and, after being inflated, is substantially tubular with cross sectional areas that increase from the injection port to the distal opening.
