Patent CA-2582779-C (CA)
Inventor: MURATOGLU ORTHUN K
IPC: C08L29/04
Filed: 2005-10-11
Granted: 2013-07-02
Abstract: The present invention provides methods of making covalently crosslinked vinyl polymer hydrogels having advantageous physical properties, and covalently crosslinked vinyl polymer hydrogel compositions made by such methods, as well as articles of manufacture comprising such covalently crosslinked vinyl polymer hydrogel compositions. The physical properties of the produced hydrogels can be adjusted by varying controlled parameters such as the proportion of physical associations, the concentration of polymer and the amount of radiation applied. Such covalently crosslinked vinyl polymer hydrogels can be made translucent, preferably transparent, or opaque depending on the processing conditions. The stability of the physical properties of the produced vinyl polymer hydrogel can be enhanced by controlling the amount of covalent crosslinks.

Abstract: The disclosed invention is based on the discovery that a cell-based therapy can be used to treat, ameliorate, manage and/or reduce the progression of clinical sequelae associated with vascular interventions or cardiovascular diseases, particularly occlusive thrombosis, restenosis, intimal hyperplasia, inflammation and vasodilation. The invention further benefits from the additional discovery that a heretofore undescribed implantable flowable composition is capable of sustaining a confluent population of sufficiently viable cells which can be effectively administered via a minimally-invasive surgical procedure without diminishing the clinical effectiveness or the viability of the cells. The disclosed invention can be used to treat vasculature as well as non-vascular tubular structures such as a fallopian tube.

Title: Method and device for measuring imaging errors in the human eye
Inventor: HEIBERGER KURT
IPC: A61B3/103
Filed: 2006-02-01
Granted: 2012-07-10
Abstract: The invention relates to a device for measuring imaging errors in the human eye (A), wherein substantial scanning of the lens of the eye (A) with a light beam of a laser diode (LD 1) determines the measuring accuracy of local refractive power. Measuring accuracy of locally dependent refractive power is achieved by a two-dimensionally refractable tilting mirror (KS) which is embodied in the form of a micro-scanner mirror with the aid of piezomotors (PM  1, PM 2) for positioning and by electrically controllable liquid lenses (FL 1, FL 2). As a result, it is possible to manufacture the measuring device as small as possible, enabling it to be integrated into a processing laser (LD 2) in order to monitor the result of treatment with a laser (LD2) during individual adaptation of contact lenses, intraoccular lenses or surgical correction of the retina in situ and to calculate data of a required correction.

The drive and bearing assembly includes a drive block mounted to extend within the hollow of the support body at the first end thereof. The drive block includes a motor provided with a torque transmitting driveshaft. A first coupling assembly is connected to the driveshaft of the motor and the support body. The first coupling assembly is operable to transmit the torque produced by the motor to the support body to thereby urge rotation of the brush cutting head. The drive and bearing assembly further includes a second coupling assembly mounted to extend within the hollow of the support body at the second end thereof. The second coupling assembly has a first end and a second end. The second end of the coupling assembly is fixedly attached to the support body. The second coupling assembly includes a bearing support member, a bearing assembly housed within the bearing support member and a coupling member. The bearing assembly is mounted in surrounding relation with a portion of the coupling member to thereby allow free rotation of the coupling member relative to the bearing support member.

Granted: 2011-08-30
Abstract: A downhole abrading tool (10) has a body (20) with a first end (12) for connection to a drill string, a cutting end (14), an exterior surf ace (21), a drilling fluid passageway (26), a valve (80), and a chamber (18). Upon exposure of the chamber to a wellbore fluid pressure due to excessive wear on the cutting end, the valve opens. The opening of the valve permits drilling fluid to flow from the drilling fluid passageway, through the exterior surface and into the wellbore. The flow of drilling fluid through the exterior surface causes a pressure drop that is detected at the surface by an operator of the downhole abrading tool. The valve movement may also cause the release of taggants, or indicators, into the drilling fluid that may also be detected by the operator, either visually or with the aid of detection equipment.
