Publication number: 20180280029Abstract: A vascular remodeling device is provided. The device has an anchor portion, sized for deployment in a blood vessel, that is radially expandable from a collapsed state to an expanded state. The device also includes a distal portion sized for deployment in a blood vessel. The distal portion is radially expandable from a collapsed state to an expanded state and has a distal face that is sufficiently occlusive in the distal-to-proximal direction to perform a therapeutic blocking function in an aneurysm neck. The device also has an intermediate portion that interconnects a distal end of the anchor portion and a proximal end of the distal portion. In some embodiments, the anchor portion and/or distal portion has a plurality of interconnected struts.Type: ApplicationFiled: June 7, 2018Publication date: October 4, 2018Inventors: Masoud Molaei, Evan Epstein, Gabriel Newell, Quang Tran

Publication number: 20180280030Abstract: A compression device is used to increase intra-luminal pressure within the upper esophageal sphincter of a patient in order relieve an impact of an abnormal or defective upper esophageal sphincter anatomy, physiology, or functionality. In one implementation, the compression device is used in conjunction with an external pressure sensing device to determine the external pressure that is to be applied to the cricoid for a specific patient. The compression device can be a means for the management and/or treatment of abnormal upper esophageal sphincter functionality, or a means for strengthening an esophageal sphincter of a subject, or a means for curing esophageal reflux disease of a subject, or a means for improving vocal function in a subject, or a means for managing lung aspiration, or a means for applying cricoid pressure during anesthesia intubation, or a means for stabilizing body structures such as during medical imaging or radiation treatment.Type: ApplicationFiled: June 4, 2018Publication date: October 4, 2018Inventors: Nick T. Maris, James S. Miller, Reza Shaker, Timothy Bachman, Nathan Schlueter, Eugene Paul Maloney, Eric David North, Paul Raine, Peter Alex

Publication number: 20180280033Abstract: A trocar for preparing pilot holes, tunnels and other spaces within bone includes a piercing tip, a cutting element, and an expansion element for expanding the cutting element radially outwardly with respect to a longitudinal axis of the trocar. The cutting element includes one or more cutting blades. The trocar also includes a hollow shaft. The hollow shaft can include one or more apertures axially and radially aligned with the one or more cutting blades. The expansion element can include an activation rod housed inside the hollow shaft. The one or more cutting blades can be in the form of two opposed cutting blades separated by a gap, the two opposed cutting blades being radially displaceable with respect to the longitudinal axis. The activation rod can include a wedge that partially enters the gap between the two opposed cutting blades to displace the cutting blades to an expanded position.Type: ApplicationFiled: November 15, 2016Publication date: October 4, 2018Inventor: Erik Papenfuss

Publication number: 20180280035Abstract: A mill head for replaceable attachment to a base so as to collectively form a bone mill. The mill head includes shell with: a first opening in which bone stock is introduced into the head; and a second opening through which the bone chips are discharged. A cutting device is mounted in the shell to both rotate and move laterally. Attached to the cutting device are coupling features for engaging a drive spindle able to rotate the cutting device. Also attached to the housing is an alignment feature. The alignment feature engages a complementary alignment feature associated with the drive spindle so as a result of the engagement of the alignment features, the cutting device moves within the shell so that the cutting device coupling features are positioned to engage the drive spindle.Type: ApplicationFiled: June 4, 2018Publication date: October 4, 2018Applicant: Stryker CorporationInventors: Richard Burmeister, Gary Kalinka, Michael Peterson
