Methods, apparatus and systems for measuring pressure and/or for quantitative or qualitative measurement of analytes within the eye or elsewhere in the body. Optical pressure sensors and/or optical analyte sensors are implanted in the body and light is cast from an extracorporeal light source, though the cornea, conjunctiva or dermis, and onto a reflective element located within each pressure sensor or analyte sensor. The position or configuration of each sensor's reflective element varies with pressure or analyte concentration. Thus, the reflectance spectra of light reflected by the sensors' reflective elements will vary with changes in pressure or changes in analyte concentration. A spectrometer or other suitable instrument is used to process and analyze the reflectance spectra of the reflected light, thereby obtaining an indication of pressure or analyte concentration adjacent to the sensor(s). The wavelength of the interrogating beam of light may vary to control out potential interference or inaccuracies in the system.

Implantable devices and methods for measuring intraocular, subconjunctival or subdermal pressure and/or analyte concentration

This invention is a system, an apparatus and a method for measuring biomechanical properties of cornea and the intraocular pressure in vivo. More than one dimensional topographic information of the cornea is recorded and analyzed before and during the fluid discharge and converted to the stress-strain relationship and other cornea parameters, for example the cornea thickness and radius of curvature, etc. The deformation of cornea is initiated by a non-contact fluid discharge whose profile is predetermined and monitored in real time. Utilizing this non-contact topographer, the true intraocular pressure can be derived from the response of the cornea due to the impact of fluid discharge and the corneal topographic parameters. One embodiment of this invention includes the use of a multiple color strobe light/multiple detector system to record the corneal topographic deformation due to the impact of fluid discharge.

A catheter combination is described using a percutaneous transluminal transmitter for transmitting energy to a localized area. The combination includes a catheter having a hollow tubular member. A transmitter combination for partial insertion into the catheter includes a continuous central conductor terminating in a tip for receiving and transmitting a signal to the tip. A dielectric material surrounds at least a significant portion of the central conductor, and a continuous coaxial conductor surrounds the dielectric material for receiving and transmitting a signal to a point adjacent the tip to form an antenna for transmitting energy to tissue when the transmitter is placed into biologic tissue. A coating around the coaxial conductor covers the coaxial conductor. A signal generator is coupled to the central conductor and the coaxial conductor for applying a signal between the central and coaxial conductors to transmit energy from the tip of the central conductor.

Percutaneous transluminal catheter and transmitter therefor

A spectacle system for individuals having impaired vision having at least one ocular implant lens is provided which includes an objective lens for forming a magnified image of a distant object on the individual's retina and a spectacle frame for suporting the objective lens on an individual's head in a spaced apart relationship with the implanted intraocular lens. An actuator and driver are provided to enable manually controlled non-rotational and translational movement of the objective lens along an optical axis defined by the objective lens and the implanted intraocular lens.
