Publication number: 20200324089Abstract: This invention concerns a neurosurgical kit comprising a catheter (1) and a guide tube (2). The catheter (1) comprises a distal section of tubing (11) having a distal end with a port or ports for delivering fluid to a target site within the brain. The distal section of tubing (11) has an outer diameter that is smaller than an internal diameter of the guide tube (2). The catheter (1) and guide tube (2) are arranged such that, when the catheter (1) is inserted into the guide tube (2) to locate the port or ports at the target site, a recess (14) is provided in a distal end section of the guide tube (2) between the guide tube (2) and the distal section of tubing (11) of the catheter (1).Type: ApplicationFiled: June 24, 2020Publication date: October 15, 2020Applicant: RENISHAW PLCInventors: Stephen Streatfield GILL, Maxwell Roy WOOLLEY, Thomas GILL

Publication number: 20180015273Abstract: 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.Type: ApplicationFiled: September 27, 2017Publication date: January 18, 2018Applicant: RENISHAW (IRELAND) LIMITEDInventor: Stephen Streatfield GILL

Publication number: 20160346505Abstract: 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.Type: ApplicationFiled: August 12, 2016Publication date: December 1, 2016Applicant: RENISHAW (IRELAND) LIMITEDInventors: Stephen Streatfield GILL, Matthew David Frederick STRATTON, Hugo George DERRICK

Patent number: 7183109Abstract: A regulatory region is shown, a nucleotide sequence of approximately 3kb which provides improved seed preferred, and particularly embryo preferred expression in plants. Methods of use are also shown in preferentially expressing a heterologous protein to the embryo tissue of a plant. The sequence is particularly useful in expression of heterologous proteins to the embryo of monocotyledonous plants, particularly cereals, and maize.Type: GrantFiled: May 11, 2005Date of Patent: February 27, 2007Assignee: Applied Biotechnology InstituteInventors: Stephen Streatfield, Robert Love, Jeff Bray

Publication number: 20030200566Abstract: Plants are engineered to express proinsulin or insulin. The plants can be used as a source of the protein for a variety of purposes. Plant tissue can be orally administered to animals to replace the necessity of injection of insulin. Alternatively, the protein can be extracted from plant tissue and delivered to animals. Plant produced proteins can also provide a less expensive and more readily available source of the protein as reagents or in other experimentation involving insulin proteins.Type: ApplicationFiled: March 7, 2003Publication date: October 23, 2003Applicant: ProdiGene, Inc.Inventors: Stephen Streatfield, John Howard
