Patent CA-2671295-A1 (CA)
Title: Self-cleansing bladder drainage device
Inventor: TIHON CLAUDE
IPC: A61F2/04
Filed: 2000-06-01
Abstract: An urethral drain having deep external drainage channels, a low-profiled bladder retention segment, and a reversibly detachable collection segment, facilitates the draining of urine and fluids from the bladder. The low-profiled retention means minimizes bladder irritations and the deep external channels reduce the occurrence of infections. Incorporation of a reduced diameter smooth segment on the catheter, proximate the location of the external urethral sphincter allows the patient to void normally and at will. Modifying the size of this smooth segment aids the function of a defective sphincter in controlling urine leakage. The drain can be worn concealed within the urethra. Flushing action from normal voiding washes out particulate matters in the urethra and the concealed drain further minimizes contamination. Together, these features improve quality of life for patients needing catheterization.

Title: Facilitating handover between a source and a target base station without using a random access channel (rach)
Inventor: DAMNJANOVIC ALEKSANDER
IPC: H04W24/00
Filed: 2008-03-17
Abstract: Systems and methodologies are described that facilitate handing over mobile device communications in a wireless network from a source base station to a target base station without using a random access channel (RACH). In this regard, the source base station can request shared data bandwidth resources from the target base station on behalf of the mobile device and assign the resources to the mobile device. The mobile device can calculate a timing difference between the source and target base stations and can handover communications by transmitting over the shared data bandwidth using the timing difference to generally provide correct timing for the transmission. To this end, the target base station can have transmission time intervals where it allows transmitting with an extended cyclic prefix to ensure more reliable handover for the mobile device.

Title: Mesh comprising ecm
Inventor: NIELSEN LENE FELDSKOV
IPC: A61L31/10
Filed: 2008-03-07
Abstract: Herein is disclosed the utility of discontinuous regions of Extraceullar Matrix Proteins (ECM) in promoting cell growth in a Mesh. When the described scaffolds are applied on top of inert materials, cell in-growth is promoted and the attachment of the mesh is properly secured. In one aspect, the mesh has a side with reduced cellular in-growth and a side with enhanced in-growth. Combining inert materials with cell attractive materials such as ECM can do this. This is particularly advantageous for use as hernia implant. Here, the mesh should adhere only to the abdominal wall (on one side of the mesh) without adhering to the intestines. In one aspect of the invention, the inert material is elongated and coated on both ends. This is particularly advantageous for use as slings. Here, the mesh will adhere to the anchorage points in the ends of the sling, and still allow urethral redistribution as a consequence of bladder emptying.

Abstract: An oil well includes a wellbore (2), below ground level (4), which extends to an oil reservoir (6). The wellbore includes a casing (8) within which is arranged a progressing cavity pump (PCP) 10 which includes an inlet (12) at its lower end and is connected at its upper end to production tube (14). An annulus (16) is defined between the pump (10)/tube (14) and the casing (8). The annulus communicates with the reservoir and includes a head (20) of reservoir fluid. A water based formulation which comprises an optionally cross-linked polyvinylalcohol can be poured down the annulus (16) and pass under gravity to the reservoir (6), immediately upstream of inlet (12). The formulation may improve the performance and efficiency of the pump (10) due to its ability to increase the mobility of the oil in the reservoir immediately upstream of the pump (10) and/or enhance the ability of the oil to enter the pump inlet. Furthermore, by improving mobility and/or reducing the level of back pressure when the oil enters the pump inlet (or any other constriction) the rate of flow of oil from the reservoir into the wellbore may be increased resulting in an increased rate of oil production.
