Abstract: Methods and devices for implanting an intra-ocular pressure sensor within an eye of a patient are provided herein. Methods include penetrating a conjunctiva and sclera with a distal tip of a fluid-filled syringe and positioning the pressure sensor within a vitreous body of the eye by injecting the sensor device through the distal tip. The sensor device may be stabilized by one or more anchoring members engaged with the sclera so that the pressure sensor of the sensor device remains within the vitreous body. Methods further include advancing a sensor device having a distal penetrating tip through at least a portion of the sclera to position the sensor within the vitreous body and extracting of the sensor devices described herein by proximally retracting the sensor device using an extraction feature of the sensor device.

Abstract: The invention relates to a cavity determination apparatus for determining a cavity (3) within an object (2), in particular, for determining the location and dimensions of a heart chamber within a person. A bendable segment of an introduction element (5) is arranged within the cavity in different arrangements, wherein curves defined by the bendable segment in the different arrangements are determined by a curve determination unit (7). A cavity reconstruction unit (8) reconstructs the cavity based on the determined curves. Thus, not only single locations within the cavity are acquired and used for reconstructing the cavity, but larger curves. A lot of spatial information can therefore be acquired and used very fast. This allows reconstructing the cavity with improved quality in a relatively short time.

Abstract: The subcutaneous injection device contains a pump and a mechanism for inserting a cannula into the patient's skin. The cannula is fixedly positioned relative to the pump and the insertion mechanism has a flexible surface adhering to the skin. The flexible surface is positioned relative to the cannula in such a way that in a first position the tip of the cannula is concealed by the surface and in a second position the cannula is exposed beyond the surface. The insertion mechanism brings the surface from the first to the second position, thereby pulling the skin against the tip of the cannula.

The video camera pixel locations may be mapped to the physical space. A xy-scan device of the laser system may be calibrated by defining control parameters for actuating components of the xy-scan device to scan a beam to a series of locations. Optionally, the beam may be scanned to a series of locations on a fluorescent plate. The video camera may be used to capture reflected light from the fluorescent plate. The xy-scan device may then be calibrated by mapping the xy-scan device control parameters to physical locations. A desired z-depth focus may be determined by defining control parameters for focusing a beam to different depths. The video camera or a confocal detector may be used to detect the scanned depths.

Abstract: A patient treatment unit and method analyzes and treats pain in tissues by applying an electrical pulse train to the affected tissue. The impedance of the affected tissue is measured, and the measured impedance is correlated to a level of pain in the patient. The pulse train is further applied in response to the measured impedance to reduce the patient's pain. The patient treatment unit includes a probe stimulus generator that outputs the pulse train. The treatment unit also includes a pair of probes for contacting the patient's body and receiving the pulse train. The pulse has improved shaping based on isolation of high voltage from a low voltage control. The unit further includes a body impedance analysis circuit that senses voltage and current via the probes when the probes are contacting the patient and observe the impedance. A monitor is electrically coupled to the body impedance analysis circuit and provides an indication of the measured impedance indicative of the patient's level of pain in real-time.
