Publication number: 20130195540Abstract: A fail-safe attachment is provided for coupling an exoskeletal prosthesis to a patient limb having a bone anchored mounting post with an external fixation structure. The fail-safe attachment comprises a first component adapted for connection to the fixation structure, and a second component adapted for connection to the prosthesis. A safety release mechanism is provided normally retaining the prosthesis in a rigid substantially motion-free interconnected relation to the fixation structure, said safety release mechanism responding to a force overload condition to permit relative movement between the prosthesis and the fixation structure. The safety release mechanism comprises a bending force release mechanism responsive to a bending force overload condition to permit the separation of the second component relative to said first component.Type: ApplicationFiled: April 12, 2011Publication date: August 1, 2013Applicant: STANMORE IMPLANTS WORLDWIDE LIMITEDInventors: Robert Michael Wozencroft, Katrina Orme

Patent number: 8303575Abstract: A mechanism which constrains the spatial location of a working or a focal point of a tool (103), has a manipulator (101) and a remote center mechanism (102) mounted thereon. The manipulator (101) provides at least one degree of freedom for positioning the remote center mechanism (102) which itself provides at least a further degree of freedom for positioning a tool holder suitable for holding the tool (103) which is to be constrained in operation with respect to a remote center point. The orientation of the tool holder is adjustable while still maintaining the position of the remote center point fixed with respect to the manipulator (101).Type: GrantFiled: August 18, 2006Date of Patent: November 6, 2012Assignee: Stanmore Implants Worldwide LimitedInventor: Ferdinando Maria Rodriguez Y Baena

Patent number: 7241313Abstract: A surgical implant comprises a core region and a porous surface region extending over at least part of the core region. The surface region has a predetermined pore volume fraction. A method of manufacturing a surgical implant comprises: (i) loading metallic powder having a predetermined particle size distribution around a pre-formed core in a sealable capsule; (ii) reducing pressure within the capsule to a predetermined pressure below atmospheric pressure; (iii) pressurising the capsule with a process gas to a predetermined pressure higher than the predetermined pressure of step (ii); (iv) sealing the capsule; (v) heating the pressurised sealed capsule at an elevated temperature and an elevated pressure for a predetermined time to produce an implant precursor; (vi) cooling the sealed capsule, and; (vii) heating the implant precursor for a predetermined time at an elevated temperature and a predetermined pressure below atmospheric pressure, whereby to generate porosity in the implant precursor.Type: GrantFiled: August 12, 2002Date of Patent: July 10, 2007Assignee: Stanmore Implants Worldwide LimitedInventors: Paul Unwin, Gordon Blunn, Michael Herbert Jacobs, Mark Andrew Ashworth, Xinhua Wu
