Abstract: An ophthalmic surgical cartridge has a fluid pump with a pump chamber and a drive chamber which are separated by a fluid-tight and ion-tight partition element. A body fluid is suppliable to the pump chamber and a drive fluid is suppliable to the drive chamber. A deformation or change in position of a portion of the partition element is achievable with the drive fluid which increases the second volume in size and decreases the first volume in size to drain the body fluid from the pump chamber. The drive chamber has a front side wall with an edge zone in which only a single passage opening is provided, through which the drive fluid is suppliable into the drive chamber to fill the drive chamber with the drive fluid, and through which said drive fluid can be drained from the drive chamber to remove the drive fluid from the drive chamber.

Abstract: A cassette for a console of an ophthalmosurgical system for treating an eye is configured for insertion into a cassette receiving region of the console and has a fluid pump configured to deliver a treatment fluid, a tube for attachment to a handpiece, and a connection unit secured against detachment, of a cassette-side end of the tube to a cassette housing of the cassette. The connection unit includes an attachment stub arranged on the cassette housing and has a through opening for the treatment fluid, and a plug-in connector arranged on the cassette-side end of the tube and likewise has a through opening for the treatment fluid, with the plug-in connector, when it is connected to the attachment stub, being held in a fluid-tight manner with respect to the attachment stub and so as to be able to rotate about a longitudinal axis of the through opening.

Abstract: An implantable medical device (IMD) including a power supply, a sensing device and/or a stimulation device, a control unit, a magnetic resonance (MR) detection unit, and at least two magnetic field sensors. The power supply is connected to one or more of the sensing device, the stimulation device, the control unit, the MR detection unit and the magnetic field sensors. The control unit is connected to the sensing device and/or stimulation device, to the MR detection unit, and to the at least two magnetic field sensors. The at least two magnetic field sensors are arranged spatially separately from one another and the MR detection unit determines a spatial and/or temporal gradient of magnetic field strengths detected by the at least two magnetic field sensors and transmitted to the MR detection unit. The MR detection unit detects an MR field and transmits an MR signal to the control unit.
