Publication number: 20170290599Abstract: Disclosed herein is an intravascular device for removing thrombosis and recovering a blood flow, wherein the attachment of thrombosis can be facilitated since a plurality of minute protrusions are formed on the surface of the stent structure. The present inventive concept is able to significantly minimize any separation of the thrombosis when the device for removing thrombosis and recovering a blood flow is transferred to the outside of a human body in such a way that a plurality of minute protrusions are formed on the surface of the stent structure, and the attachment of the thrombosis to the stent can be facilitated.Type: ApplicationFiled: September 22, 2015Publication date: October 12, 2017Inventors: Sung-Won YOUN, Young-Cheol LEE

Publication number: 20170290600Abstract: Catheter-delivered endovascular medical devices are described. The devices may include a pull wire attached to a distal body. The distal body may be formed of a distal body outer body comprising a basket comprised of a plurality of cells defined by a plurality of basket strips and a distal body inner body located in the interior of the distal body outer body and comprising a plurality of distal braided mesh openings formed by a plurality of woven linear strands. The distal braided mesh openings may be smaller than the cells when the device is in the relaxed state. Methods of using and making the devices are also described.Type: ApplicationFiled: June 21, 2017Publication date: October 12, 2017Inventor: Arthur John Ulm, III

Publication number: 20170290602Abstract: Arthroscopic cutters are used for resecting tissues, such as meniscal tissues, in meniscectomies or other arthroscopic procedures. The arthroscopic cutters have a shaft assembly with openable-closeable jaws at a working end of the shaft. A handpiece having a motor drive may be detachably coupled to a hub on a hub end of the handpiece. When the shaft is coupled to the handpiece, the motor drive will couple to the jaw structure to open and close the jaw structure to cut meniscal and other tissues.Type: ApplicationFiled: April 10, 2017Publication date: October 12, 2017Applicant: RELIGN CorporationInventors: Aaron Germain, Jeffrey Norton, Salvatore G.

Publication number: 20170290603Abstract: Rotational atherectomy devices and systems can remove or reduce stenotic lesions in blood vessels by rotating an abrasive element within the vessel. The abrasive element can be attached to a distal portion of an elongate flexible drive shaft that extends from a handle assembly. In particular embodiments, the handle assembly includes a compressed gas driven turbine member that drives rotation of the drive shaft. The turbine member can be rotatably attached to a carriage that is longitudinally translatable in relation to a housing of the handle assembly. The handle assembly can include a latch mechanism that when actuated allows the carriage to translate to a proximal-most position. While the carriage is in the proximal-most position, an open pathway is created so that a guidewire can be slidably passed through the handle assembly and a lumen of the drive shaft.Type: ApplicationFiled: April 6, 2016Publication date: October 12, 2017Inventors: Cassandra Ann Piippo Svendsen, Charles Anthony Plowe, Albert Seiden Benjamin, Paul Joseph Robinson, Evan Leingang

Publication number: 20170290604Abstract: An atherectomy catheter having an inner shaft which rotates a distal rotary tissue borer with a helical cutting surface which enables the catheter to out it and cross a CTO. Additionally, the atherectomy catheter has a distal cutting element rotated by an outer drive shaft configured to cut material from the wall of a vessel at a treatment site as the catheter is pushed distally through the treatment site. The atherectomy catheter includes a collection chamber positioned proximally of the cutting element and rotary tissue borer. The atherectomy catheter may include means to direct material cut from the treatment site into the collection chamber, means to break down larger portions of material that may block or clog the collection chamber and means of transporting the material collected from the treatment site to a proximal opening in the atherectomy catheter.Type: ApplicationFiled: June 26, 2017Publication date: October 12, 2017Inventors: Jenny Zeroni, Robert VanPelt, JR., Cory Sills, Scott Petersen, Nick van der Lugt

Publication number: 20170290605Abstract: The invention generally relates to intracavitary medical devices and methods for using the devices. In one aspect, the devices comprise: a tube comprising a longitudinal body having opposed proximal and distal ends, and at least three lumens extending there between; and an expandable balloon region located at the distal end of the tube; wherein at least one lumen comprises at least one of: a drainage lumen which opens at a portion of the distal end of the tube and configured to allow fluid communication from a body cavity into the drainage lumen, an inflation lumen connected to an interior of the balloon region and configured to enable passage of a distending fluid to control expansion and contraction of the balloon region, and an instillation lumen which opens at a portion of the distal end of the tube and configured to allow a fluid to be introduced from the instillation lumen into the body cavity.Type: ApplicationFiled: April 11, 2017Publication date: October 12, 2017Inventor: Younes Noaman Bakri

Publication number: 20170290606Abstract: A cosmetic device includes a housing having a handle portion, a head assembly coupled to the handle portion, and a drum assembly within the head assembly. The drum assembly includes a drum having an outer surface configured to abrade the skin or nails of a user during rotation of the drum. The device further includes a electromechanical drive system located within the housing and configured to rotate the drum. The head assembly is configured to rotate about an axis that is substantially perpendicular to the axis of rotation of the drum.Type: ApplicationFiled: April 7, 2016Publication date: October 12, 2017Inventor: Wai Wah Yiu

Publication number: 20170290607Abstract: A minimally invasive screw with double threaded plugs is provided, for connecting to a connecting rod. The screw includes an inner threaded plug, an outer threaded plug, a lengthened arm connector, a press block and a pin with a hollow ball head. The connecting rod can be fixed to the lengthened arm connector via the press block, the inner and outer threaded plugs, to prevent the vertebral body from rotating and loss of intervertebral height when the vertebral body is distracted and pressurized.Type: ApplicationFiled: September 3, 2016Publication date: October 12, 2017Inventors: Wenzhi Zhang, Xiyi Huang, Guoshuai Miu, Yaling Wang, Wensheng Lu, Hongyan Li
