Patent number: 11129643Abstract: A neurosurgical apparatus includes a guide device and a neurosurgical instrument is disclosed. The guide device includes a tube for insertion into the brain and a head attached to the proximal end of the tube for affixing the guide device to a hole formed in the skull. The head has a passageway therethrough in communication with the bore of the tube such that the bore of the tube and the passageway through the head define an internal channel through which a neurosurgical instrument can be passed into the brain of the subject. The neurosurgical instrument is for insertion to a desired brain target through the internal channel of the guide device. The apparatus includes one or more sealing elements for providing a fluid tight seal between the internal channel of the guide device and the exterior of the neurosurgical instrument to prevent fluid leakage from guide tube.Type: GrantFiled: February 27, 2013Date of Patent: September 28, 2021Assignee: RENISHAW PLCInventors: Steven S Gill, Attila Antalfy

Patent number: 8781589Abstract: The invention is a method of hermetically bonding a ceramic part to a metal part by welding and brazing a component assembly comprised of metal parts, a ceramic part, and a metal ferrule having alignment lips. The ceramic part is preferably a hollow tube of partially-stabilized zirconia that is brazed to an alignment ferrule that is preferably titanium or a titanium alloy, such as Ti-6Al-4V. On one end the component assembly is brazed to an end cap for closure. On the other end the alignment ferrule is preferably brazed to a ring that is preferably comprised of a noble metal, such as platinum, iridium, or alloys of platinum and iridium. The ring is laser welded to an eyelet that is preferably comprised of a noble metal.Type: GrantFiled: April 29, 2013Date of Patent: July 15, 2014Assignee: Alfred E.

Patent number: 8447402Abstract: The invention is a component assembly and method of hermetically bonding a ceramic part to a metal part by welding and brazing a component assembly comprised of metal parts, a ceramic part, and an intermediate metal ferrule. The ceramic part is preferably a hollow tube of partially-stabilized zirconia that is brazed to an alignment ferrule that is preferably titanium or a titanium alloy, such as Ti-6Al-4V. On one end the component assembly is brazed to an end cap for closure. On the other end the alignment ferrule is preferably brazed to a ring that is preferably comprised of a noble metal, such as platinum, iridium, or alloys of platinum and iridium. The ring is then laser welded to an eyelet that is preferably comprised of a noble metal.Type: GrantFiled: March 26, 2007Date of Patent: May 21, 2013Assignee: Alfred E.

Publication number: 20120237785Abstract: Forming an implantable component assembly by bonding a stainless steel part to a titanium part by heating a component assembly comprised of the titanium part, the stainless steel part, and a compact filler layer of titanium-nickel particulate material placed between the two parts and heated at a temperature that is less than the melting point of either the stainless steel part or the titanium part. The component assembly is held in intimate contact at temperature in a non-reactive atmosphere for a sufficient time to develop a hermetic and strong bond between the stainless steel part and the titanium part. The bonded component assembly is optionally treated with acid to remove any residual free nickel and nickel salts, to assure a biocompatible component assembly, when implanted in a human body.Type: ApplicationFiled: April 18, 2012Publication date: September 20, 2012Applicant: ALFRED E.

Patent number: 8177116Abstract: A method of bonding a stainless steel part to a titanium part by heating a component assembly comprised of the titanium part, the stainless steel part, and a laminated titanium-nickel filler material placed between the two parts and heated at a temperature that is less than the melting point of either the stainless steel part or the titanium part. The component assembly is held in intimate contact at temperature in a non-reactive atmosphere for a sufficient time to develop a hermetic and strong bond between the stainless steel part and the titanium part. The bonded component assembly is optionally treated with acid to remove any residual free nickel and nickel salts, to assure a biocompatible component assembly, if implanted in living tissue.Type: GrantFiled: December 6, 2011Date of Patent: May 15, 2012Assignee: Alfred E.

Patent number: 8043454Abstract: The invention is a method of making a hermetic via in a ceramic substrate that is comprised of noble metal powder in a glass-free paste that contains an admixture of a particulate phase of niobium pentoxide. The electrically conductive platinum provides excellent electrical conductivity while the niobium pentoxide phase prevents shrinkage of the paste during thermal processing and binds to both the ceramic and the noble metal particulates in the via, thus maintaining a hermetic seal around the via.Type: GrantFiled: January 10, 2011Date of Patent: October 25, 2011Assignee: Alfred E.

Patent number: 7157150Abstract: A method of bonding a stainless steel part to a titanium part by heating a component assembly comprised of the titanium part, the stainless steel part, and a compact titanium-nickel filler material placed between the two parts and heated at a temperature that is less than the melting point of either the stainless steel part or the titanium part. The compact filler material is made of particles, preferably spheres, of discrete layers of nickel and titanium metal that react with each other and with the stainless and titanium parts to form a strong assembly when thermally processed. The component assembly is held in intimate contact at temperature in a non-reactive atmosphere for a sufficient time to develop a hermetic and strong bond between the stainless steel part and the titanium part.Type: GrantFiled: April 14, 2004Date of Patent: January 2, 2007Assignee: Alfred E.

Publication number: 20060138202Abstract: A method of braze bonding a stainless steel part to a titanium part by heating a component assembly comprised of the titanium part, the stainless steel part, and a very thin substantially pure nickel foil filler material placed between the two parts and heated at a temperature that is greater than the temperature of the eutectic formed between the titanium part and the substantially pure nickel filler material, but that is less than the melting point of either the filler material, the stainless steel part, or the titanium part. The component assembly is held in intimate contact at temperature in a non-reactive atmosphere for a sufficient time to develop a hermetic and strong bond between the stainless steel part and the titanium part. The bonded component assembly is optionally treated with acid to remove any residual free nickel and nickel salts, to assure a biocompatible component assembly for implantation in living tissue.Type: ApplicationFiled: February 16, 2006Publication date: June 29, 2006Applicant: Alfred E.
