An ocular disorder treatment implant includes an anchor and a therapeutic agent. The implant has a body with first and second end portions. The implant is configured to transport fluid from the anterior chamber of an eye to a physiological outflow pathway of the eye. The body has at least one inlet opening at the first end portion and at least one outlet opening at the second end portion such that the inlet and outlet openings are in fluid communication and define an axis therebetween. The anchor extends substantially perpendicularly to a part of the axis between the openings, and at least one outlet opening is configured to be positioned in the physiological outflow pathway. One implant has two outlet openings, and the anchor is disposed closer to one of the outlet openings.

A heat producing device is placed in contact with a heat exchanger that is fluidically coupled to a fluid pump. The fluid pump operates to pumps fluid through a closed fluidic system between the heat exchanger and a spot where the heat can be dissipated. In an aspect, an actuator forces fluid to be pumped without passing through a wall of the pump. One aspect uses an impedance pump as the pumping element.

The present invention relates to a system for three-dimensional (3-D) acoustic imaging of a scattering structure using information from a two-dimensional (2-D) image. The system uses a characterized sensor array to emit a signal from the sensor array into an object of interest to generate at least one 2-D representation of the object of interest. The 2-D representation comprises a plurality of x and y coordinate pairs and at least one candidate scattering structure. The candidate scattering structure comprises a shape defined by at least one pair of x and y coordinates. The candidate scattering structure shape is restricted to at least one pair of x and y coordinates. The pair of x and y coordinates of the candidate scattering structure shape are then compared with a first coordinate-dependent response function to assign an x, y, and z position of a scattering structure in 3-D space.

Determining instantaneously three-dimensional coordinates of large sets of points in space using apertures associated with cameras or camera parts. An embodiment associates information from the apertures with different portions of the imager, so that portions on the imager do not overlap.

A multilayered impedance pump is formed by an inner tube and an outer tube which have different mechanical characteristics. The outer tube is relatively stiff, and can be used for a structural material. The inner tube is excitable, and a gel is placed between the inner and outer tube. The actuator actuates the gel to cause pressure waves along the inner tube.

A shunt system for use in a human body that is formed from a length of tube that is configured as a pump. The length of tube may be configured as a hydroimpedance pomp, whose surfaces are pressed to pump fluid in the specified direction and way. The length of tube that forms the pump may be connected to shunt inlet and outlet parts, and may also include a valve that is adjustable to prevent back draining of fluid.
摘要:
A three-dimensional imaging system uses apertures through which images are projected. The image through each aperture is obtained by a different camera element. The camera elements can be totally physically separate, multiple receiving parts of a single camera, or a single camera which is effectively spatially modulated so that the single camera receives different images at different times. The outputs from the camera are used to form three-dimensional information about the object.

Surgical methods and related medical devices for treating glaucoma are disclosed. The method comprises trabecular bypass surgery, which involves bypassing diseased trabecular meshwork with the use of a stent implant. The stent implant is inserted into an opening created in the trabecular meshwork by a piercing member that is slidably advanceable through the lumen of the stent implant for supporting the implant insertion. The stent implant is positioned through the trabecular meshwork so that an inlet end of the stent implant is exposed to the anterior chamber of the eye and an outlet end is positioned into fluid collection channels at about an exterior surface of the trabecular meshwork or up to the level of aqueous veins.
摘要:
The subject system hardware and methodology combine disparate cameras into a cohesive gesture recognition environment. To render an intended computer, gaming, display, etc. control function, two or more cameras with non-coaxial axes are trained on a space to detect and lock onto an object image regardless of its depth coordinate. Each camera captures one 2D view of the gesture and the plurality of 2D gestures are combined to infer the 3D input.

A new and improved sterile ultrasound probe cover, said cover comprising two layers. The inner layer being placed inside the outer layer, the cover is gelled inside both inner and outer layers. The present invention can be manufactured inexpensively, is easy to use, and can cover an ultrasound probe in sterile manner very quickly, in amount of time which is appealing to practitioners and can be used without using an assistant.
