20080249412Preoperative and Intra-Operative Lens Hardness Measurement by Ultrasound - The present disclosure provides methods, systems, techniques and apparatus related to an instrumentation used to classify tissue before and/or during removal. The tissue can include any hard tissue/soft tissue interface, such as a cataract within a lens. Before an operation, an ultrasound image can be provided that gives a full scan of the targeted region, e.g., a lens, and provide a hardness profile. The profile could include a two or three dimensional map of the tissue hardness, assisting a surgeon to choose a suitable surgical procedure and strategy. During the operation, hardness measurements can be carried out real-time, in a constant manner, while the surgeon is working. This data can allow the handpiece to automatically adjust to the surgical conditions including the tissue hardness, increasing surgical performance, decreasing surgical procedure time and reducing the rate of complications.10-09-2008
20080262512Thrombolysis In Retinal Vessels With Ultrasound - Systems and methods are described providing for the use of ultrasound energy to effect the dislodging of one or more blood clots inside blood vessels. Such clots can include those inside retinal vessels, especially in patients with central retinal vein occlusion. Embodiments of the present disclosure may be used for any retinal arterial or venous occlusion. In exemplary embodiments, a small probe can be inserted into the eye of a patient and placed over the retinal vessels. Acoustic streaming created by the probe can be directed to an area or region including targeted blood vessels, resulting in increased flow in one or more retinal veins and facilitating or effecting mechanical dislodging of one or more blood clots in the targets blood vessels. Exemplary embodiments can utilize ultrasonic energy produced at a frequency of approximately 44 MHz to 46 MHz with pulse repetition frequencies of approximately 100 Hz to 100 kHz.10-23-2008
20080319319Intraocular Ultrasound Doppler Techniques - Systems and methods are disclosed providing for the use of ultrasound energy to measure blood flow within blood vessels by Doppler velocity measurement. Directional high-frequency pulsed-wave Doppler measurements can be made with a suitable ultrasonic needle transducers for in vivo measuring of blood flow. A needle probe can include a ultrasonic material such as PMN-PT. Such blood flow measurements can be made in any part of the body, e.g., in the central retinal vein and branch retinal veins.12-25-2008
20090030323Ultrasound and Microbubbles in Ocular Diagnostics and Therapies - The present disclosure described methods, systems, and techniques for applying contrast-enhanced ultrasound to locate areas of blockage within retinal vessels and to break up clots that are causing damage. In addition to identifying the damaged area, the researchers anticipate that the initial image may serve as a baseline for monitoring the effect of treatment on the vessel, which may be achieved in multiple ways. The vibration effect of the ultrasound itself may suffice to dislodge clots. The microbubbles may also be coated or filled with medication, with ultrasonic shock waves activating the coating or causing mini explosions to release the medicine. Loading the microbubbles with a therapeutic agent, visualizing their presence at the diseased site using the ultrasound diagnostic mode, and then activating the microbubbles to release their contents at the targeted lesion could be a powerful and effective way to reverse occlusion without harming other areas of the eye or body.01-29-2009
20090177245SUBCHOROIDAL RETINAL PROSTHESIS - Embodiments of the present disclosure are directed to utilization of one or more arrays that are placed under the choroid. In this approach, an array is placed under the choroid. To achieve this, a scleral incision can be made without cutting the underlying choroid or retina. The array can then be inserted into the space between the sclera and choroid and is pushed to the desired place. It is possible to make several of such scleral incisions in each quadrant of the eye to insert arrays of similar or different shapes into the subchoroidal space. Following insertion of the electrode array the scleral wound may be sutured around the cable to make the array and the eye more stable.07-09-2009

20090117158Transdermal sustained release drug delivery - Provided herein are microprojections and microprojection arrays wherein a microprojection is coated with at least two layers. One layer comprises a biologically active agent, for example, a PTH agent and optionally other excipients. Another layer, which is generally, initially devoid of active agent comprises a polymer or a mix of polymers to provide controlled release, for example sustained release, of the biologically active agent contained in the first layer. Microprojections coated with multiple layers, some layers containing a biologically active agent and other layers containing a polymer for controlled release are also contemplated herein.05-07-2009
