Abstract
Abstract The invention relates to a one-piece or multipiece application system for applying plastic masses out of a receptacle. The application system (10) comprises a funnel-shaped outlet piece (16) adapted to the receptacle and an elongate application part (30), wherein along the inner surfaces of all parts of the application system no shoulder is formed which could impair the application of the plastic mass.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
120 words
An application system for applying bone cement out of a receptacle into a medullary cavity, the application system comprising: an outlet piece adapted to receive the receptacle, the outlet piece having a smooth inner surface and an outside; and an elongate application part attachable to the outside of the outlet piece, the application part having a longitudinally extending space which mates with the outlet piece with no inner shoulder, the application part formed of a deformable, flexible material and having a plurality of longitudinally extending folds which freely fold, allowing the application part to be inserted into the medullary canal in a freely folded state and then deform and expand due to bone cement introduced into the longitudinally extending space.
Claim 2
Dependent Claim
120 words
An application system for applying bone cement out of a receptacle into a medullary cavity, the application system comprising: an outlet piece adapted to receive the receptacle, the outlet piece having a smooth inner surface and an outside; and an elongate application part attachable to the outside of the outlet piece, the application part having a longitudinally extending space which mates with the outlet piece with no inner shoulder, the application part formed of a deformable, flexible material and having a plurality of longitudinally extending folds which freely fold, allowing the application part to be inserted into the medullary canal in a freely folded state and then deform and expand due to bone cement introduced into the longitudinally extending space.
Claim 3
Dependent Claim
15 words
The application system according to claim 1, wherein the outlet piece comprises a funnel-shaped part.
Claim 4
Dependent Claim
16 words
The application system according to claim 2, wherein the outlet piece comprises a rotationally non-symmetrical funnel.
Claim 5
Dependent Claim
12 words
The application system according to claim 1, which has a two-piece structure.
Claim 6
Dependent Claim
24 words
The application system according to claim 1, wherein the application part in its unfolded condition has a length of approximately 3 to 25 cm.
Claim 7
Dependent Claim
19 words
The application system according to claim 1, wherein outlet piece comprises a bayonet catch for receipt of the receptacle.
Claim 8
Dependent Claim
45 words
The application system according to claim 1, wherein the application part is mounted at least partially over the outside of the outlet piece, and wherein the outside of the outlet piece comprises at least one sharp-edged extension having an undercut for holding the application part.
Claim 9
Dependent Claim
51 words
The application system according to claim 1, wherein the longitudinally extending folds are located at a free end of the application part and extend for only a portion of the application part, and wherein the application part comprises a non-foldable attachment part for mating with and attaching to the outlet piece.
Claim 10
Dependent Claim
29 words
The application system according to claim 1, wherein the outlet piece is formed of a material selected from the group consisting of: TPX, rubber, silicon, polycarbonate, metal and glass.
Claim 11
Dependent Claim
18 words
The application system according to claim 1, wherein the application part is formed of a smooth elastic material.
Claim 12
Dependent Claim
15 words
The application system according to claim 10, wherein the application part is formed of TEFLON.
Claim 13
Independent Claim
154 words
A method of applying bone cement out of a receptacle into a medullary cavity, the method comprising: attaching an outlet piece to the receptacle, the outlet piece having a smooth inner surface and an outside; and attaching an elongate application part having a longitudinally extending space to the outside of the outlet piece such that the longitudinally extending space mates with the outlet piece with no inner shoulder, the application part formed of a deformable, flexible material and having a plurality of longitudinally extending folds which freely fold, allowing the application part to deform and expand due to bone cement introduced into the longitudinally extending space; inserting the application part in a freely folded state into a medullary canal; and introducing bone cement through the outlet piece into the application part such that the bone cement deforms and expands the application pair such that the applied bone cement essentially completely fills the medullary cavity.
Claim 14
Independent Claim
154 words
A method of applying bone cement out of a receptacle into a medullary cavity, the method comprising: attaching an outlet piece to the receptacle, the outlet piece having a smooth inner surface and an outside; and attaching an elongate application part having a longitudinally extending space to the outside of the outlet piece such that the longitudinally extending space mates with the outlet piece with no inner shoulder, the application part formed of a deformable, flexible material and having a plurality of longitudinally extending folds which freely fold, allowing the application part to deform and expand due to bone cement introduced into the longitudinally extending space; inserting the application part in a freely folded state into a medullary canal; and introducing bone cement through the outlet piece into the application part such that the bone cement deforms and expands the application pair such that the applied bone cement essentially completely fills the medullary cavity.
Claim 15
Dependent Claim
10 words
The method of claim 12 for applying PMMA bone cements.
Claim 16
Dependent Claim
37 words
The method of claim 12, further comprising the step of: after filling the application part, retracting the application part longitudinally out of the medullary cavity while leaving the applied bone cement in position in the medullary cavity.
