Publication number: 20130158516Abstract: A variable-stiffness guidewire system which comprises an elongated flexible guidewire. The guidewire has a body and a tensioning head coupled to the body. The tensioning head is slidably moveable with respect to a guidewire collar coupled to the body via a tensioning wire to adjust a stiffness of the guidewire. The guidewire includes one or more protrusions within a conduit of the guidewire collar which applies a frictional force to the tensioning wire to maintain the tensioning head a desired distance from the collar, thereby maintaining the desired stiffness in the guidewire. A tool can be utilized with the guidewire to engage the guidewire head and move the guidewire head a desired distance from the guidewire collar to achieve a desired stiffness.Type: ApplicationFiled: February 19, 2013Publication date: June 20, 2013Applicant: Wright-Ahn Technologies, LLCInventors: Jay Ralph Wright, Samuel Seunghae Ahn

Publication number: 20090131831Abstract: A variable stiffness guidewire comprises a outer body including a plurality of coil windings that are oriented in a first direction. The outer body has a proximal end and a distal end and a hollow interior therebetween. A tension element is positioned within the hollow interior and has first and second opposed ends, wherein the second end is coupled to the distal end of the outer body. The tension element includes a plurality coil windings that are oriented in a second direction opposite to the first direction. The tension element is configured to be pulled in a direction away from the distal end of the outer body to increase a stiffness in at least a portion of the guidewire.Type: ApplicationFiled: August 15, 2008Publication date: May 21, 2009Applicant: WRIGHT-AHN TECHNOLOGIES, LLCInventors: Jay Ralph Wright, Sam Seunghae Ahn
