Patent number: 10034705Abstract: The present disclosure is directed to electrode assemblies, and specifically to struts comprising electrode assemblies and electrodes contained on the struts. The electrode assembly struts are constructed to have a low profile and to have superior strength over the length of the strut such that an electrode assembly including the strut is highly resistant to radial compression. The electrodes included on the low profile, high strength strut also is designed to have a reduced profile such that electrode assemblies including the strut and electrode can easily be used with 6 French and smaller guide catheter assemblies.Type: GrantFiled: October 23, 2014Date of Patent: July 31, 2018Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: John Jason Buysman, Ryan Kenneth Buesseler, Qingshan Ye, Victor Yevgenyevich Kotov, Gregory James Dakin, Russ Terwey, Janson Lee Ayer

Patent number: 9289540Abstract: A modified medical device substrate surface designed to improve adhesion of biomimetic surfactants to the medical device surface, thus reducing the risk of thrombosis is described. The surface modification is accomplished through either an application of a tie layer of a hydrophobic material on the substrate surface intermediate the biomimetic coating or through incorporation of a hydrophobic dopant in the polymeric substrate prior to extrusion or molding. Either method creates a hydrophobically modified surface that enhances the biomimetic surfactant bonding strength.Type: GrantFiled: May 7, 2010Date of Patent: March 22, 2016Assignee: Greatbatch Ltd.Inventor: Qingshan Ye

Patent number: 8958891Abstract: A reinforced suture sleeve designed to cover and protect a medical lead from physical damage resulting from an over tightened suture is described. The reinforced suture sleeve comprises a metallic tubular insert with at least one slot that cut through the surface of the insert in a spiraled pattern. A biocompatible and pliable polymeric body is molded over the insert. The spiraled cut slot in the metallic tubular insert provides flexibility without degrading structural integrity. An alternate embodiment comprises a polymeric body provided with an embedded fiber mesh made of polymeric fibers, metallic fibers or combinations thereof. The fiber mesh prevents an over tightened suture from cutting through the suture sleeve and damaging the medical lead.Type: GrantFiled: July 9, 2010Date of Patent: February 17, 2015Assignee: Greatbatch Ltd.Inventors: Larry Kane, Qingshan Ye

Publication number: 20140324144Abstract: Methods and apparatus for implanting a neural stimulation lead in a patient's body are described. A lead assembly comprises a pointed-tip stylet, a stimulation lead, and an optional tube to deploy a fixation element attached to the lead. One embodiment of the implant methods starts with inserting the pointed-tip lead assembly directly into tissue. After the desired implant position is determined, the pointed-tip component is separated from the stimulation lead and removed from the tissue, leaving the stimulation lead implanted. After confirmation that the stimulation lead is in the right tissue location, the pointed-tip component is removed from the body, leaving the stimulation lead in place. The stimulation lead can be connected to a neurostimulator to delivery therapies to treat neural disorders, such as urinary control disorders, fecal control disorders, sexual dysfunction, and pelvic pain, etc.Type: ApplicationFiled: July 10, 2014Publication date: October 30, 2014Inventors: Qingshan Ye, John M.

Patent number: 8634932Abstract: Methods and apparatus for implanting a neural stimulation lead in a patient's body are described. A lead assembly for minimally invasive implantation of a stimulation lead comprises a pointed-tip stylet, a stimulation lead, and an optional tube to deploy fixation element attached on the lead. One embodiment of the implant methods starts with inserting the pointed-tip lead assembly directly into tissue. The desired implant position is determined by electric stimulation either through stimulation lead or the pointed tip. Afterwards, the pointed-tip component is separated from the stimulation lead and removed from the tissue, leaves the stimulation lead implanted. In one variation, a needle is inserted to identify the optimal stimulation site first, after mark the needle path and position, the needle is removed and a pointed-tip stimulation lead assembly is inserted along the needle path marked.Type: GrantFiled: July 21, 2009Date of Patent: January 21, 2014Assignee: Greatbatch Ltd.Inventors: Qingshan Ye, John M.

Patent number: 8175700Abstract: One or more inductors and one or more capacitors are physically disposed relative to one another in series and are electrically connected to one another in parallel to form a bandstop filter. Chip inductors and chip capacitors having spaced apart conductive terminals are physically arranged in end-to-end abutting relation to minimize electrical potential between adjacent conductive terminals. The bandstop filter may be hermetically sealed within a biocompatible container for use with an implantable lead or electrode of a medical device. The values of the inductors and the capacitors are selected such that the bandstop filter is resonant at one or more selected frequencies, such as an MRI pulsed frequency.Type: GrantFiled: October 28, 2009Date of Patent: May 8, 2012Assignee: Greatbatch Ltd.Inventors: Robert Shawn Johnson, Kishore Kumar Kondabatni, Christopher Michael Williams, Ryan Thomas Bauer, Scott Brainard, Qingshan Ye, Warren S.

Patent number: 8109908Abstract: An introducer assembly includes a sheath and a dilator. A biodegradable shroud covers the distal portion of the introducer assembly on the surface of both the sheath and the dilator. The biodegradable shroud dissolves in blood after being exposed for a predetermined time. Afterwards, the dilator can be separated from the sheath without breaking the sheath. The shroud improves movement of the introducer assembly through a venous system by preventing body tissue from getting caught in the space between the dilator and the shroud, for example should a “fish mouth” separation occur between them.Type: GrantFiled: January 22, 2009Date of Patent: February 7, 2012Assignee: Greatbatch Ltd.Inventors: Mark C.

Patent number: 8055322Abstract: Devices and methods for measuring a target ion concentration uses an electrode pair. The pair includes a working electrode and a reference electrode. The working and reference electrodes are ion-selective electrodes (ISEs). The reference ISE can include a sodium ISE. The ISE pair interacts with body fluids where a target ion concentration changes more than sodium ion concentration over time. Some ISE membranes of a pair vary essentially only in the ionophore. An ISE pair can determine the ratio of a target ion concentration to sodium ion concentration in vivo. Periodic measurement of sodium concentration in drawn blood can be used to calibrate an ISE pair and provide target ion concentration as an output. Or, a potassium/sodium ISE pair beneficially monitors potassium concentration changes over time in heart- or kidney-failure patients. Then, manual or automatic titration of a diuretic material can be implemented to maintain a desired potassium concentration.Type: GrantFiled: February 21, 2008Date of Patent: November 8, 2011Assignee: Medtronic, Inc.Inventor: Qingshan Ye

Patent number: 7993305Abstract: An improved splittable medical device introducer designed to introduce a medical device such as a lead or catheter, into a patient's vasculature without loss of blood or the introduction of air is described. The introducer assembly is designed to easily separate in a smooth tactile manner without disrupting placement of the medical device during removal of the introducer. The introducer is composed of a fluoropolymeric material which combined with an internal stress confining structure propagates a stress initiated by the operator that tears the entire introducer assembly in two without creating a jagged separated edge.Type: GrantFiled: October 22, 2009Date of Patent: August 9, 2011Assignee: Greatbatch Ltd.Inventors: Qingshan Ye, Aaron Opbroek
