Patent number: 8142367Abstract: A deflectable stylet system optimized for use in conjunction with a lead of the type having a fixation helix that is screwed into body tissue by rotation of the lead's connector pin is disclosed. The system includes an attachment that is rotatable and longitudinally slidable with respect to the handle of a deflectable stylet. A lead coupled to the attachment may be moved longitudinally with respect to a stylet to account for slight variances in the lead length. In one embodiment, the attachment couples to the lead via a pushbutton mechanism that can be locked to the lead using one hand. The attachment may be rotated to thereby rotate the lead connector. This allows for retraction and extension of a retractable fixation helix, and for further attachment or detachment of a fixation helix to adjacent tissue. In one embodiment, the attachment may be longitudinally rigidly positioned in predetermined locations with respect to the handle.Type: GrantFiled: February 26, 2008Date of Patent: March 27, 2012Assignee: Medtronic, Inc.Inventors: Kenneth C. Gardeski, Corinne A. G. Poor, William J. Clemens, Jeremy J. Odegard

Patent number: 6607496Abstract: A steerable guidewire or stylet that has increased torsional strength is disclosed. A braided structure located in the vicinity of at least the distal end of the guidewire or stylet provides for a more efficient transfer of rotational force over the length of the guidewire or stylet. The braided structure may be comprised of a flat metal ribbon wire that may optionally be reinforced with a polyimide. According to one aspect of the invention, the stylet includes an outer member, and a pull-wire located within the outer member. The pull-wire is coupled to the distal tip of the outer member such that when tension is applied to the pull-wire, the distal tip of the outer member is deflected. The distal tip of the outer member may be formed of a material having superelastic properties such as a nickel titanium alloy, whereas the proximal portion of the stylet may be formed of a material having more torsional strength.Type: GrantFiled: September 12, 2000Date of Patent: August 19, 2003Assignee: Medtronic, Inc.Inventors: Corinne A.

Patent number: 6146338Abstract: A deflectable stylet or guidewire formed of an elongated tube having a coil mounted to its distal end and a movable tension or push wire mounted within the coil and the tube, mechanically coupled to the distal end of the coil. A backbone is located within the coil, mechanically coupled to the proximal and distal ends of the coil and extending along one side of the coil. The backbone may be provided with projections extending laterally between adjacent turns of the coil and may have a generally arcuate cross section having a width greater than its arc height. In some embodiments the backbone may be formed from a tube having a slot extending longitudinally along one side thereof. In some embodiments the backbone may be attached to the coil at points between the proximal and distal ends of the coil.Type: GrantFiled: April 23, 1999Date of Patent: November 14, 2000Assignee: Medtronic, Inc.Inventors: Kenneth C.
