Patent number: 10206698Abstract: Described herein are low-profile electrodes for use with an angioplasty shockwave catheter. A low-profile electrode assembly may have an inner electrode, an insulating layer disposed over the inner electrode such that an opening in the insulating layer is aligned with the inner electrode, and an outer electrode sheath disposed over the insulating layer such that an opening in the outer electrode sheath is coaxially aligned with the opening in the insulating layer. This layered configuration allows for the generation of shockwaves that propagate outward from the side of the catheter. In some variations, the electrode assembly has a second inner electrode, and the insulating layer and outer electrode may each have a second opening that are coaxially aligned with the second inner electrode. An angioplasty shockwave catheter may have a plurality of such low-profile electrode assemblies along its length to break up calcified plaques along a length of a vessel.Type: GrantFiled: July 27, 2016Date of Patent: February 19, 2019Assignee: SHOCKWAVE MEDICAL, INC.Inventors: Doug Hakala, John M.

Patent number: 10154851Abstract: Provided herein are expandable endoscopic devices. In accordance with certain aspects of an embodiment of the invention, an endoscopic expandable device is disclosed that comprises an expandable jaw at the distal tip, a control wire connected to the jaw, a sheath enclosing the control wire, and a handle connected to the sheath or wire having an actuating trigger. The expandable jaw is configured to allow its delivery in a retracted configuration to a target site within a patient's body through the working channel of an endoscope, after which the jaw may reconfigure to an expanded configuration that is larger than the retracted configuration. This allows the expandable jaw to be easily delivered to the target site while allowing an operable jaw size that is larger than would be allowed if limited to size of the working channel.Type: GrantFiled: January 28, 2015Date of Patent: December 18, 2018Assignee: University of Maryland, BaltimoreInventors: Florence M.

Patent number: 10086191Abstract: Medical leads have one or more openly coiled filars and a distal body coupled to the openly coiled filars. The openly coiled filars provide a lead with compliance and elasticity while the distal body provides the firmness needed for placement and support of the electrodes. The openly coiled filars may transition to a linear distal portion that extends to the distal body, and the distal body may have proximal tines that fold proximally to become adjacent to the linear distal portion of the filars. The openly coiled filars may instead extend to the distal body and the proximal tines may be laterally arced to then fold against the lateral surface of the coiled filars. The tines may fold distally during explantation to allow the distal body to release and exit the body.Type: GrantFiled: January 29, 2013Date of Patent: October 2, 2018Assignee: MEDTRONIC, INC.Inventors: Eric H. Bonde, Phillip C. Falkner, Michael T. Hegland, Brian T. Stolz, Patrick D. Wells

Patent number: 9974535Abstract: A medical device for installing sutures to close an incision in tissue or human skin is disclosed. The suturing device may provide first and second arcuate needles. Once properly positioned, the first and second arcuate needles are driven through the sub-dermal layer, or alternatively through a superficial surface, of two sections of skin to be joined. This is done in arcuate fashion and at identical and symmetrical rates of angular displacement. In so doing, the sections of skin are pushed toward one another thus assuring horizontal and vertical alignment of the two sections of skin. During the driving or retraction process of the first and second arcuate needles, a suture is positioned within both the first and second sections of skin and transformed from a planar or a multi-planar serpentine orientation to a helical orientation.Type: GrantFiled: February 24, 2015Date of Patent: May 22, 2018Assignee: Surgimatix, Inc.Inventors: Jafar Syed Hasan, Wai Ngai Chin, Gary Michael Kobylewski

Patent number: 9936941Abstract: A suture manipulating instrument for passing and retrieving suture through a tissue includes a handle mechanism, an elongate shaft extending from the handle, and a working distal end. The working distal end includes a needle body, a lumen defined by the needle body, a tissue penetrating distal tip, and a lateral slot. A preformed inner member is movably disposed within the lumen of the needle. The handle mechanism is used to extend the wire from the lateral slot of the needle, and to retract the wire into the lateral slot, allowing the working end of the instrument to grasp and manipulate suture by pinning and/or trapping the suture against the needle.Type: GrantFiled: February 6, 2013Date of Patent: April 10, 2018Assignee: ArthroCare CorporationInventors: Thomas Weisel, Roger Pisarnwongs
