Patent application numberDescriptionPublished
20100318064CATHETER - A neurosurgical catheter is described for insertion into the brain parenchyma of a subject. The catheter comprises a flexible tube and has a stiff, non-porous, tip comprising at least one fluid delivery aperture. The stiff tip of the catheter may be mechanically stiffer than the flexible tube. The stiff tip may be provided by a stiff tube attached to the distal end of the flexible tube. The stiff tube may comprise a ceramic (e.g fused silica) and/or a metal. A kit comprising the catheter and a guide tube is also described. Methods of catheter implantation are also outlined.12-16-2010
20110200244METHOD, APPARATUS AND PHANTOM FOR MEASURING AND CORRECTING TOMOGRAM ERRORS - A tomogram taken on an imaging path of a tomograph is corrected by using sets of tomogram correction data for neighbouring positions on that path, in an interpolative process. An error map of a tomograph is built up by comparing tomograms of a phantom with the expected appearance of the phantom at the tomogram positions. Also provided is a phantom having a body with one or more imaging fluid receptacles formed therein.08-18-2011
20120060847HEAD CLAMP FOR IMAGING AND NEUROSURGERY - A head clamp for neurosurgery is described that includes a member for at least partially encircling the head of a subject. The first end and second end of the head clamp include first and second skull attachment portions for attaching the member to the head of a subject. A position setter, such as an indexing mechanism, is also provided that allows the member to be moved or indexed between at least two repeatable relative positions.03-15-2012
20120065496APPARATUS FOR IMAGING A BODY PART - Apparatus for imaging a body part of a subject, for example using MRI, is described. The apparatus includes a housing for at least partially surrounding a body part (e.g. a head) and a first fiducial marker assembly retained at least partially within the housing that includes one or more fiducial markers and a datum feature. The position of the datum feature is fixed relative to the one or more fiducial markers. The first fiducial marker assembly is moveable with respect to the housing and the datum feature is accessible from outside of the housing.03-15-2012

20090082758Implantable Fluid Distribution Device and Method of Fluid Delivery - An implantable fluid distribution device is described. The device includes a first inlet for receiving fluid under pressure from a remote pump. A plurality of outlets are also provided, each outlet being connectable to a fluid delivery catheter. A valve mechanism is arranged to control the passage of fluid from the first inlet to the plurality of outlets. Apparatus including the fluid distribution device, an implantable pump and a plurality of drug delivery catheters is also described. The fluid distribution device can be used to delivery drug to multiple regions in the body and the sequential delivery of drugs to different sites in the brain is disclosed.03-26-2009
20090198218NEUROSURGICAL INSTRUMENTS - A catheter assembly for insertion into the brain. The assembly comprises a first length of tubing made of a first material. A second material surrounds the first length of tubing, the second material being more flexible than the first material and having a hardness of less than 50 Rockwell E. The second material provides damping to the first length of tubing.08-06-2009
20090279815GAS BEARINGS - A rotary gas bearing is described that comprises a first part rotatable relative to a second part. The first part comprises a support member and a first portion and a second portion attached to the support member. The first portion comprises a first bearing surface and the second portion comprising a second bearing surface. Both the first portion and the second portion are attached to the support member by screw thread connections. The second part may comprise complimentary bearing surfaces. Epoxy may be used to fix the first and/or second portions to the support member. A method of determining the bearing working gap by measuring gas flow through the bearing is also described.11-12-2009
20090304314Gas Bearing Fabrication Method - A method of fabricating a bearing surface (12-10-2009
20100217236NEUROLOGICAL APPARATUS - A guide element for insertion into the brain to guide implantable instruments, wherein the guide element comprises an elongate part, the elongate ‘part having a composition of at least 80% tungsten carbide. The guide element may have a coating, such as a biocompatible plastics material which is more resilient than the elongate part.08-26-2010
