Patent number: 8992592Abstract: An endoprosthesis for deployment within a body passage includes an external tubular framework disposed about a tubular member, e.g., a metallic film having a thickness of about 50 ?m or less. The tubular member may be sandwiched between the external tubular framework and an internal tubular framework located internally of the external tubular framework and the tubular member. Whether or not the internal tubular framework is included, the endoprosthesis can be self-expanding. During deployment of the endoprosthesis using a deployment device, the external tubular framework prevents substantial frictional contact between the deployment device and the tubular member.Type: GrantFiled: December 29, 2004Date of Patent: March 31, 2015Assignee: Boston Scientific Scimed, Inc.Inventors: Masoud Molaei, John Peckham

Publication number: 20130123899Abstract: An implantable vascular prosthesis is provided for use in a wide range of applications wherein at least first and second helical sections having alternating directions of rotation are coupled to one another. The alternating helical section includes a first and second helical portions each having a flange and having adjacent ends joined directly to one another to define an apex. Each helical portion has a widened flange portion adjacent to the apex, the widened flange portions extending into a space between the helical portions. The prosthesis is configured to conform to a vessel wall without substantially remodeling the vessel, and permits accurate deployment in a vessel without shifting or foreshortening.Type: ApplicationFiled: January 3, 2013Publication date: May 16, 2013Applicant: NovoStent CorporationInventors: Eric W.

Patent number: 8157855Abstract: An inventive repositionable stent may comprise a plurality of adjacent serpentine bands connected to one another by at least one permanent connector strut and by at least one disengagable connector strut. The stent may self-expand within a bodily lumen to an intermediate deployment diameter, wherein the stent is constrained from further expansion by the at least one disengagable connector strut. The stent may be repositioned within the bodily lumen while in the intermediate deployment configuration. The disengagable connector strut may be disengaged via electrolytic detachment, whereupon the stent may expand to a full deployment diameter.Type: GrantFiled: December 5, 2003Date of Patent: April 17, 2012Assignee: Boston Scientific Scimed, Inc.Inventors: Tracee Eidenschink, John Peckham

Patent number: 7963988Abstract: A vascular graft includes a vessel structure having outer and inner wall surfaces. The vessel structure has outer and inner transverse dimensions. The vascular graft includes a fold structure which is integral with the vessel structure. The fold structure extends from the outer or inner wall surface of the vessel structure for altering the inner or outer transverse dimension thereof. A method for making the vascular graft facilitates formation of the fold structure.Type: GrantFiled: June 23, 2005Date of Patent: June 21, 2011Assignee: Boston Scientific Scimed, Inc.Inventors: John Peckham, Frank A.

Publication number: 20080029612Abstract: An improved shell-and-tube steam instantaneous heat exchange system of a closely coupled feedback design which overheats water in the heat exchanger portion of the system and then blends the water, as needed, with proportional amounts of cold water to achieve the correct outlet temperature for a wide range of flow rates. The system uses at least two primary heat exchangers to provide redundancy in the case of failure of a major component of the system. Steam flow through the heat exchangers is controlled by the use of steam traps, rather than using a thermostatically controlled valve to vary the supply of steam. To obtain precise temperature control during varying water volume use, water is directed from the blended outlet of a first water tempering valve into the hot inlet port of a second water tempering valve.Type: ApplicationFiled: September 10, 2007Publication date: February 7, 2008Inventors: John Peckham, Frank Myers, Christopher Bollas
