Patent number: 11890003Abstract: A medical device includes a surgical needle, an elongated suture, and an intervening segment. The elongated suture has a first end proximate to the needle and a second end located away from the needle. The elongated suture also includes a plurality of fibers defining a mesh wall between the first and second ends. A plurality of pores extend through the mesh wall, at least some which are in the macroporous size range of greater than 200 microns for facilitating tissue integration when introduced into a body. The intervening segment is disposed between and connected to either or both ends of the elongated suture and the needle. The intervening segment includes one or more fibers of the plurality of fibers and has a cross-sectional dimension smaller than a cross-sectional dimension of the mesh wall such that the intervening segment facilitates indirect attachment of the elongated macroporous mesh suture to the needle.Type: GrantFiled: July 9, 2021Date of Patent: February 6, 2024Assignee: Northwestern UniversityInventor: Gregory A.

Patent number: 10881394Abstract: A medical device includes a surgical needle attached to an elongated mesh suture. The suture is constructed of macroporous flat wall that facilitates and allows tissue integration into the suture core subsequent to introduction to the body, thereby preventing suture pull-through and improving biocompatibility.Type: GrantFiled: September 13, 2017Date of Patent: January 5, 2021Assignee: NORTHWESTERN UNIVERSITYInventors: Gregory Dumanian, Anandev Gurjala

Publication number: 20200129172Abstract: A medical device includes an elongated suture having a tension indicator carried by the elongated suture. The tension indicator signals over-tensioning of the elongated suture when a tensile load applied along an axial direction of the elongated suture exceeds a predetermined tensile load, thereby preventing over-tensioning of the suture and collapsing of the suture. Advantageously, the tension indicator serves as an integrated feedback device that provides instantaneous feedback when tensioning a suture, rather than having to use an external measuring device to determine the amount of tensile load applied to the suture.Type: ApplicationFiled: October 29, 2018Publication date: April 30, 2020Inventors: Gregory A. Dumanian, Adom Dumanian

Patent number: 10279157Abstract: Embodiments for superficial tissue compliance modulation and negative pressure wound therapy for stabilization of a chronic percutaneous implant are disclosed. An external cap is coupled to a compliance gradient of progressively decreasing stiffness. Together the external cap and compliance gradient act as a stress shield that allows forces that would otherwise act on the skin at the skin-implant interface to be dissipated over a larger area. In addition, negative pressure and fluids may be applied through negative pressure and fluid adapters, respectively, to the skin-implant interface, the status of which may be further monitored through the use of one or more sensors.Type: GrantFiled: March 14, 2014Date of Patent: May 7, 2019Assignee: Rehabilitation Institute of ChicagoInventors: Todd A. Kuiken, Gregory A. Dumanian, Jason M. Souza

Publication number: 20180360453Abstract: A medical device includes a surgical needle and an elongated suture. The suture has a first end attached to the surgical needle and a second end located away from the surgical needle. The suture includes a mesh wall and a plurality of pores extending through the mesh wall. At least some of the pores in the macroporous size range of greater than 200 microns and adapted to facilitate tissue integration through the mesh wall of the suture when introduced into a body. The suture is configured to resist a tensile load applied along an axial direction between the first and second ends of the elongated suture such that upon overloading the mesh wall collapses upon itself resulting in apparent suture elongation, collapsed diameter, and/or reduction in pore size.Type: ApplicationFiled: August 28, 2018Publication date: December 20, 2018Inventors: Gregory A. Dumanian, Justin Herbert, Adom Dumanian

Publication number: 20180042608Abstract: A medical device includes a surgical needle attached to a mesh suture having anti-roping elements. The suture is constructed of a macroporous mesh wall that facilitates and allows tissue integration subsequent to introduction to the body, thereby preventing suture pull-through and improving biocompatibility. Advantageously, the anti-roping elements serve to maintain the desired construct of the mesh wall when undergoing axial tensile loads by resisting elongation and loss of outer mesh wall macroporosity, while still permitting a flattening of the suture with lateral loading.Type: ApplicationFiled: March 1, 2016Publication date: February 15, 2018Inventors: Gregory Dumanian, Justin Herbert
