| 20120310182 | IMPLANTABLE FLUID ROUTER - An implantable fluid router is described that includes one or more inlets, one or more outlets and at least one gas vent for removing gas from liquid routed from the one or more inlets to the one or more outlets, The implantable router may be used with implantable drug delivery apparatus. A catheter device including such a fluid router is also described. | 12-06-2012 |
| 20120302959 | PERCUTANEOUS DRUG DELIVERY APPARATUS - An implantable percutaneous fluid delivery device is described that includes a subcutaneous base portion having one or more ports for supplying fluid to one or more implanted catheter devices and a percutaneous portion including an extracorporeal surface. The one or more ports of the subcutaneous base portion are accessible from the extracorporeal surface of the percutaneous portion. The subcutaneous base portion is at least partially insertable into a complementary recess formed in a bone, the subcutaneous base portion including one or more features for gripping the internal surface of such a complementary recess thereby directly anchoring the subcutaneous base portion to the bone. The device may be used to route fluid to neurosurgical catheters optionally via a router unit. | 11-29-2012 |
| 20120123391 | NEUROLOGICAL 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. | 05-17-2012 |
| 20120065496 | APPARATUS 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 |
| 20120060847 | HEAD 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 |
| 20110282319 | Catheter and guide tube for intracerebral application - A catheter for use in neurosurgery, and a method of positioning neurosurgical apparatus. The catheter has a fine tube arranged for insertion into the brain parenchyma of a patient with an external diameter of not more than 1.0 mm. The catheter and method may be used in stereotactically targeting treatment of abnormalities of brain function, and for the infusion of therapeutic agents directly into the brain parenchyma. This is advantageous when a therapeutic agent would have widespread unwanted effects which could be avoided by confining the delivery to the malfunctioning or damaged brain tissue. | 11-17-2011 |
| 20110200244 | METHOD, 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 |
| 20110009879 | APPARATUS FOR STEREOTACTIC NEUROSURGERY - A skull mount ( | 01-13-2011 |
| 20100318064 | CATHETER - 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 |
| 20100318061 | Catheter - The invention relates to rigid surgical devices formed from rigid ceramics such as zirconium dioxide. In particular, the invention relates to a neurosurgical catheter formed from extruded zirconium dioxide. The invention also relates to an advancement means for advancing or retracting such a device along an axis of insertion into a patient. | 12-16-2010 |
| 20100312193 | Neurosurgical cap - The invention relates to a cap for use in neurosurgery. The cap may be applied to a bore hole in a patient's skull, allowing the entry and removal of neurosurgical instruments, whilst providing an openable seal over the bore hole. | 12-09-2010 |
