Abstract:
A bone cement is provided that includes a solid component and a liquid component. The solid component and liquid component are mixed together to form the bone cement. After completion of the solid and liquid component mixing, the bone cement has an initial viscosity effective for manual application or manual injection onto or into a targeted anatomical location, e.g., bone, and the cement has stable viscosity range that over both time and temperature is effective for uniformly filling the targeted anatomical location, for example an osteoporotic bone or a fractured vertebral body, with minimal to no leakage of the cement from the targeted anatomical location. Additionally, both the initial viscosity and the stable viscosity of the bone cement are within a range that renders the bone cement effective for injection with a manually operated syringe or multiple syringes.
Abstract:
The invention relates to a preparation and application device (10) for implant materials consisting of at least one powder or granulate component and one liquid component, which are to be prepared immediately before use. Said device comprises a first container (12) which holds the powder or granulate component in a sterile, closed-off manner; and a second container (54) which holds the liquid component in a sterile, closed-off manner and which can be connected to the first container (12). Means are provided for producing an overflow connection between the two containers, for forcing the liquid component out of the second container and into the first container (12) and for internally, homogeneously mixing the components in the first container by moving a mixing mechanism (30) which is situated in the first container, on a mixing shaft (28) that is guided out of the container in a sealed manner. The first container is configured in such a way that it can be connected to a source of negative pressure. The mixing shaft (28) that is guided out of the first container (12) is hollow and joins a hand pump (34) for producing negative pressure at its external end, also being connected to said hand pump (34). In the completely pushed-in position, the hollow mixing shaft (28) is provided with a through opening in the area which is guided through the container wall in a sealed manner, said through opening being connected to an admission channel which opens out in the container wall in this area, which is provided with a self-closing valve (24) and which is guided into the inside of the container. A measuring device (26) which indicates the negative pressure in the container can be connected to the first container (12) and the housing (36) of the hand pump (34) is configured in such a way that it is suitable for use as a handle for moving the mixing shaft (28).
Abstract:
Flüssigkeitsbehälter mit Sollbruchstelle (4), die von einem Elastomerseptum (3) abgedeckt ist. Der Behälter bildet einen Hohlkörper (10) aus einem einzigen Material, das gegenüber kritischen Flüssigkeiten, wie Arzneimittel, kompatibel ist. Das Elastomerseptum (3) und die Sollbruchstelle (4) sind mit einer Hohlnadel (51) durchstoßbar, um Flüssigkeit aus dem Behälter zu entnehmen.
Abstract:
The invention relates to a bone cement consisting of a hydrophilic component and a hydrophobic component, wherein biodegradable material is deposited in pores in the bone cement via the hydrophilic component.
Abstract:
Liquid container with a predetermined break point (4), which is covered by an elastomer septum (3). The container forms a hollow body (10) made of a single material that is compatible with critical liquids such as medicines. The elastomer septum (3) and the predetermined break point (4) can be pierced by a hollow needle (51) in order to withdraw liquid from the container.
Abstract:

Abstract:
Die Anmeldung betrifft eine Vakuum-Mischvorrichtung (1) für Knochenzement, bei welcher das Monomer aufgrund anliegenden Vakuums und eines im Monomerbehälter (10) vorhandenen Gasvolumens in einen Mischbehälter (2) gedrückt wird.
Abstract:
Verfahren zur Herstellung von Knochen-Implantatmaterial mit verbesserter mechanischer Beanspruchbarkeit auf der Basis von Formkorpern aus porosem Implantatmaterial, vorzugsweise porosem Hydroxylapatit-Keramikmaterial. Die Poren der Formkorper aus Keramikmaterial werden mit einer aus einer pulverformigen Komponente, die im Wesentlichen aus einer Mischung von Hydroxylapatit- und Kalziumsulfatpulver besteht, wobei das Hydroxylapatitpulver aus C synthetisch hergestellten, gefollten hochreinen kristallinen Nano-Partikein besteht, die eine Kristallgrol e von 10 bis 20 nm Breite und 50 bis 60 nm Lange aufweisen, mit Wasser zu einer flie13fâhigen Konsistenz aufbereiteten Füllmasse gefüllt und die in den Poren befindliche Füllmasse wird dann verfestigt.
