Patent number: 10076460Abstract: A method and wearable system and for enhancing human balance and gait and preventing foot injury through neurological stimulation of the foot and the ankle. Subthreshold stimulation for neurosensory enhancement is provided via electrodes or vibrational actuators, or combination thereof, disposed in or on a wearable a platform, such as an insole, sock shoe, removable shoe insert, or applied without the support of a platform, to the skin surface of an individual. Suprathreshold stimulation for therapeutic purposes, such as improving blood flow, is also provided by the vibrational actuators. The actuators and electrodes are driven by bias signals generated by a bias signal generator that is coupled to a controller. The signal generator under the control of the controller is adapted to generate a non-deterministic random signal, a repetitive pattern or series of patterns.Type: GrantFiled: November 12, 2012Date of Patent: September 18, 2018Assignee: Trustees of Boston UniversityInventors: Jason D. Harry, James J. Collins, James B. Niemi, Attila A. Priplata, Stephen J. Kleshinski

Publication number: 20180092764Abstract: A stent includes a first section and a second section. The second section is aligned with the first section along a longitudinal axis of the stent. Each section includes a plurality of expandable modules and a plurality of bridging modules. Each expandable module includes a plurality of strut elements that join together at a plurality of apices. Each bridging module includes bridging elements that connect an apex of a first module with an apex of a second module. The plurality of expandable modules or the plurality of bridging modules in the first section are more radially stiff than the plurality of expandable modules or the plurality of bridging modules in the second section such that at least a portion of the first section is configured to be placed in a region of a vein subjected to physiologic compression.Type: ApplicationFiled: May 15, 2017Publication date: April 5, 2018Inventors: Craig L.

Publication number: 20170325929Abstract: A blood clot filter, collapsible toward a central longitudinal axis into a collapsed configuration for insertion into a blood vessel and radially expandable outwardly from the longitudinal axis to an expanded configuration for contact with the inner wall of the blood vessel at two longitudinal spaced locations. A first plurality of elongate arms, in the expanded configuration, curve outwardly from the longitudinal axis toward the leading end of the filter to form a first filter basket and to center a hub at the trailing end of the filter within the vessel. A second plurality of elongate legs angle outwardly away from the longitudinal axis toward the leading edge of the filter in the expanded configuration to form a second filter basket opening toward the leading end. The ends of these legs include hooks, at least a portion of which is a reduced cross sectional area relative to the cross sectional area of the adjacent leg to permit the hooks to bend and straighten.Type: ApplicationFiled: February 23, 2017Publication date: November 16, 2017Applicant: C.R.

Publication number: 20170181835Abstract: An embolic protection device comprises a tubular filter body attached to a sheath. The tubular filter body has an open upstream end and a generally closed downstream end for capturing emboli. A self-opening passage through the emboli capture end of the tubular filter body allows multiple catheters to be advanced from the sheath or otherwise into the filter body simultaneously or sequentially. The sheath is attached to a peripheral support structure near the emboli capture end of the filter body to facilitate deployment and retrieval of the filter body through a restraining delivery catheter.Type: ApplicationFiled: April 25, 2016Publication date: June 29, 2017Inventors: Stephen J. Kleshinski, Scott M. Russell, Amir Belson

Patent number: 9629675Abstract: A hypotube based deliver system is used to position one or more elements in position for treatment within the body. The elements may include electrodes, sensors or injection ports or even anchors. The hypotubes may have pre-set shapes or are plastically deformed prior to positioning as they exit a positioning device. There are methods of providing therapy using the hypotubes including mixed mode therapies are also described.Type: GrantFiled: October 19, 2012Date of Patent: April 25, 2017Assignee: Confluent Medical Technologies, Inc.Inventors: Stephen J. Kleshinski, Christopher P. Cheng

Patent number: 9615909Abstract: A blood filter includes a hub, a plurality of legs, and a plurality of arms. Each of the legs includes a hook at a distal end thereof, a first linear segment extending substantially parallel to a hub longitudinal axis, a second linear segment extending obliquely with respect to the longitudinal axis at a first angle, and an intermediate linear segment coupled to the first and second segments, the intermediate segment extending obliquely with respect to the longitudinal axis at a second angle less than the first angle. Each of the arms has a free end closer to the longitudinal axis than the hook of each of the legs. The free ends of the arms are spaced radially transverse to the longitudinal axis at substantially the same radial distance.Type: GrantFiled: April 29, 2016Date of Patent: April 11, 2017Assignee: C.R. Bard, Inc.Inventors: Adrian C. Ravenscroft, Stephen J. Kleshinski

Patent number: 9283065Abstract: A method and an apparatus for anchoring a medical implant device within a blood vessel or other body passageway are described herein. An anchor delivery system houses one or more expandable anchors connected to the medical implant device. The anchors remain housed in a non-expanded configuration until the medical implant device has been placed in a desired position within the body, and then the anchors are propelled through a body wall where each anchor expands outwardly from an anchor shaft. In one configuration, each anchor is formed as a compressible closed loop which extends outwardly from an anchor shaft and loops back to cross over and extend beyond the anchor shaft. To propel the anchors, a drive shaft is connected to a triggering unit which, when activated, causes the drive shaft to drive the anchor shafts in a direction such that the anchors are propelled through the body wall.Type: GrantFiled: April 1, 2013Date of Patent: March 15, 2016Assignee: Nitinol Devices and Components, Inc.Inventors: Stephen J.

Publication number: 20160008003Abstract: Vascular delivery systems configured to deliver an implant to a location within a vasculature can include one or more control wires controllable by a user to detach the implant from the delivery system. Control wires can cause a feature of the delivery system to mechanically engage a hub at a proximal end of an implant. Proximal or distal movement of the control wire can allow the feature to disengage from the hub, thereby allowing release of the implant.Type: ApplicationFiled: March 14, 2014Publication date: January 14, 2016Inventors: Stephen J. KLESHINSKI, Karl S. HALDEN

Patent number: 8758395Abstract: The present invention relates generally to a device and method for preventing the undesired passage of emboli from a venous blood pool to an arterial blood pool. The invention relates especially to a device and method for treating certain cardiac defects, especially patent foramen ovales and other septal defects, through the use of an embolic filtering device capable of instantaneously deterring the passage of emboli from the moment of implantation. The device consists of a frame, and a braided mesh of sufficient dimensions to prevent passage of emboli through the mesh. The device is preferably composed of shape memory allow, such as nitinol, which conforms to the shape and dimension of the defect to be treated.Type: GrantFiled: July 19, 2005Date of Patent: June 24, 2014Assignee: SeptRx, Inc.Inventors: Stephen J.
