20090157002CATHETER HAVING COMMUNICATING LUMENS - A catheter having a plurality of longitudinal lumens for removing biological, natural and/or man-made materials from cavities, ducts, vessels, or other locations in a patient's body. The multi-lumen catheter comprises a longitudinally-extending suction lumen with suction holes through which materials pass into the lumen in response to suction forces generated by a source of negative pressure coupled to a proximal end of the lumen. A longitudinally-extending vent lumen coupled to a source of at least neutral vent pressure through, for example, an opening to ambient air at the proximal end of the lumen, and preferably, through vent holes disposed along a length of the catheter.

20090292246CASSETTE FOR A HIDDEN INJECTION NEEDLE - A system for injecting a fluid medicament into a patient includes a drive mechanism, and a cassette loaded with a pre-filled hypodermic syringe. When the cassette is loaded, the syringe is held firmly inside and the cassette can be selectively engaged with the drive mechanism. The drive mechanism has two motors. A first motor initially moves the hypodermic syringe from a position inside the cassette where its needle is concealed, to a position where the needle extends from the cassette for insertion into a patient for an injection. With the needle inserted, a second motor pushes the syringe stopper to expel a fluid medicament from the syringe. After an injection, the first motor withdraws the syringe back into concealment inside the cassette, to again firmly hold the syringe on the cassette. The cassette and syringe, in combination, can then be removed from the drive mechanism and discarded.11-26-2009

A shaft supported to rotate in axial direction and to connect to the drill drive that the shaft can be rotated by the drill drive. The adapter comprises a disc which is connected to the shaft in such manner that the disc rotates along when the shaft rotates. The disc comprises an attachment in an eccentric arrangement or the disc is inclined towards the rotation axis of the shaft. The adapter is connected to the lavage system by second fastener so that the rotating disc drives the lavage system. The adapter is connected to the lavage system by means of the second fastening facility in such manner that the pestle drives the lavage system and hits periodically onto a membrane of the lavage system.06-06-2013
20080200877Fluid Exchange Catheter System - A catheter system that can be used for concurrent fluid infusion and aspiration in humans, animals and biological material, at a wide range of flow rates, without any blockage problems. The system has devices that control the infused liquid's pressure changes accordingly to the aspirated liquid's pressure changes, in order to allow accurate and safe fluid exchange flow control and create changes of pressures at the catheter's tip that do not allow the catheter's blockage.08-21-2008
20110224613HYPODERMIC INJECTION SYSTEM - The invention relates to a hypodermic injection system having a direct-drive motor for moving a ram towards an injectate chamber for discharging injectate therein through a discharge orifice.
