Patent number: 7214201Abstract: A guide wire, and a method for the manufacture thereof, having a core and a plastic jacket enclosing the core. The plastic jacket comprises a proximal portion formed of a first plastic material and a distal jacket portion formed of a second plastic material. The distal end of the proximal jacket portion and the proximal end of the distal jacket portion substantially abut each other and are of substantially equal outer diameters so as to form a smooth transition between the proximal and the distal jacket portions.Type: GrantFiled: December 17, 2004Date of Patent: May 8, 2007Assignee: Boston Scientific Scimed, Inc.Inventors: Paul H. Burmeister, Richard E. Cappetta, Steven S. Hackett, Paul Slaikeu

Patent number: 7063674Abstract: A guide wire, and a method for the manufacture thereof, having a core and a plastic jacket enclosing at least a portion of the core. In some embodiments, the plastic jacket comprises a proximal portion formed of a first plastic material and a distal jacket portion formed of a second plastic material. In some embodiments, the core member has a proximal portion and a distal portion, and a first plastic jacket is disposed about the proximal portion and a second jacket formed of a fluoroelastomer is disposed about the distal portion.Type: GrantFiled: October 9, 2002Date of Patent: June 20, 2006Assignee: SciMed Life Systems, Inc.Inventors: Paul H. Burmeister, Richard E. Cappetta, Steven S. Hackett, Paul Slaikeu

Patent number: 6908443Abstract: A guide wire, and a method for the manufacture thereof, having a core and a plastic jacket enclosing at least a portion of the core. In some embodiments, the guidewire also includes a radiopaque coil disposed about a first portion of the core wire. The polymer jacket includes a first portion disposed about the radiopaque coil, and a second portion adjacent the first portion and overlaying and in contact with a second portion of the core wire. In some embodiments, the plastic jacket comprises a proximal portion formed of a first plastic material and a distal jacket portion formed of a second plastic material.Type: GrantFiled: November 20, 2001Date of Patent: June 21, 2005Assignee: SciMed Life Systems, Inc.Inventors: Paul H. Burmeister, Richard E. Cappetta, Steven S. Hackett, Paul Slaikeu

The plastic jacket comprises a proximal portion formed of a first plastic material and a distal jacket portion formed of a second plastic material. The distal end of the proximal jacket portion and the proximal end of the distal jacket portion substantially abut each other and are of substantially equal outer diameters so as to form a smooth transition between the proximal and the distal jacket portions. According to another aspect, there is provided a guide wire with a selectively formable metallic core and a plastic jacket encasing the formable core. The plastic jacket has a distal portion with a hydrophilic coating and a proximal portion without a hydrophilic coating. According to another aspect, there is provided a guide wire having a formable metallic core and a plastic jacket encasing the formable core. The plastic jacket has a distal portion that is more radiopaque than a proximal portion.Type: ApplicationFiled: October 9, 2002Publication date: February 13, 2003Applicant: Scimed Life Systems, Inc.Inventors: Paul H.

Patent number: 5443907Abstract: An improved guide for a medical insertion device includes a core, a jacket of hydrophobic polymer surrounding the core, and a mixture of hydrophobic and hydrophilic polymer coated onto the jacket. The hydrophobic polymer of the coating is the same as or compatible with the hydrophobic polymer of the jacket, resulting in improved bonding between the jacket and coating. The hydrophilic polymer of the coating provides a slippery surface which facilitates insertion of the device into a vein or other organ. The hydrophilic polymer has reduced tendency to leach or dissolve away, because it is ensnared with the hydrophobic polymer of the coating.Type: GrantFiled: December 7, 1994Date of Patent: August 22, 1995Assignee: Scimed Life Systems, Inc.Inventors: Paul Slaikeu, Paul H. Burmeister, Richard E. Cappetta, Steven S. Hackett
