Patent number: 10814127Abstract: An electrical stimulation lead for a target nerve includes a sleeve having an inner surface and an outer surface, the inner surface defines a nerve channel. A longitudinal slit extends from the outer surface to the nerve channel and along an entire length of the sleeve. A width of the slit retains the target nerve within the nerve channel when the sleeve is closed and releases the target nerve when open. A plurality of electrodes are disposed on the inner surface of the sleeve. A flexible transition element electrically couples a lead body to the plurality of electrodes. Upper and lower sections of the sleeve rotates about a common hinge line (e.g., like a clam shell) located directly opposite the longitudinal slit. The material along the common hinge line remains “elastic” when the sleeve is moved from closed to open, and vice-versa.Type: GrantFiled: February 3, 2017Date of Patent: October 27, 2020Assignee: BOSTON SCIENTIFIC NEUROMODULATION CORPORATIONInventors: Ranjan Krishna Mukhari Nageri, Tiffany Shen

Patent number: 10639485Abstract: An operating-room cable-assembly for an electrical-stimulation system includes a lead connector with a lead passageway defined in a housing. Contacts disposed in the housing engage terminals of a lead when the lead is operationally-inserted into the lead passageway. A first biased tab is disposed in a first tab lumen defined in the housing.

Patent number: 9987482Abstract: A lead anchor includes a flexible housing having a first end and a second end opposite to the first end, the flexible housing defining a lead lumen forming a continuous passageway through the flexible housing. The lead anchor also includes a compressible retention ring disposed within the flexible housing and around a portion of the lead lumen. The retention ring defines an uncompressed position in which the retention ring has an elongate shape, with a major axis and a minor axis, to hold a portion of a lead received within the lead lumen. The retention ring further defines a compressed position achieved by compressing opposite ends of the major axis of the retention ring to transition the retention ring to a more circular shape that allows the lead to slidingly pass through the retention ring. Upon release of the compression, the retention ring returns to the uncompressed position.Type: GrantFiled: May 22, 2015Date of Patent: June 5, 2018Assignee: Boston Scientific Neuromodulation CorporationInventors: Ranjan Krishna Mukhari Nageri, Geoffrey Abellana Villarta
