Publication number: 20190053807Abstract: An occlusive medical device system may include an elongate shaft having a lumen extending longitudinally through a tubular body portion and a plurality of retaining arms extending distally from the tubular body portion. An occlusive medical device may include a proximal tubular mounting portion fixed to an expandable occlusive element. A release wire may be axially translatable between a distal engagement position and a proximal released position, the release wire having a distal engagement portion and a distal retention portion distal of the distal engagement portion. The distal engagement portion may be configured to engage the plurality of retaining arms in the distal engagement position, thereby urging the plurality of retaining arms into releasable engagement with the proximal tubular mounting portion, wherein when the release wire is in the proximal released position, the plurality of retaining arms is deflectable radially inward to disengage from the proximal tubular mounting portion.Type: ApplicationFiled: August 15, 2018Publication date: February 21, 2019Applicant: Boston Scientific Scimed, Inc.Inventors: Nicholas Lee Tassoni, Khoi Le

Publication number: 20190053808Abstract: A hub assembly for use with an endoscopic assembly of a reposable surgical clip applier includes an outer housing defining a channel therethrough, a driver gear slidably disposed within the channel, a transmission gear slidably and rotatably supported within the channel, and a display gear slidably and rotatably supported within the channel. Each of the driver gear, transmission gear, and display gear is configured for reciprocal movement within the channel. Distal advancement of the driver gear causes a corresponding distal advancement of the transmission gear and distal advancement of the transmission gear causes a corresponding distal advancement of the display gear. The transmission gear is caused to the rotated in a first direction during each distal advancement of the driver gear and the display gear is caused to be rotated in the first direction during a predetermined distal advancement of the transmission gear.Type: ApplicationFiled: July 10, 2018Publication date: February 21, 2019Inventors: Jacob C.

Publication number: 20190053809Abstract: A surgical vessel clip applier handle is provided and has a head unit capable of being flipped relative to a handle body having a front end pivotally connected to the head unit. An embedding opening is formed on the top of a barrel part of the handle body. Two slides blocks are disposed inside the barrel part at a front position and a rear position. The front part of a grip part of the handle body has a trigger having a linkage assembly disposed between the trigger and the slide blocks. The invention is capable of installing and removing conventional clamping assemblies by simply flipping the head unit; when the head unit is flipped back, the rear end of the clamping assembly will connect to the slide blocks via the embedding opening, the linkage assembly thereby drives the clamping assembly to clamp while the trigger is being pulled by a user.Type: ApplicationFiled: August 7, 2018Publication date: February 21, 2019Inventors: Kuo-Yang Chang, Chien-Wei Sun

Publication number: 20190053811Abstract: An embolic device for treating aneurysms or other vascular disorders may be more compliant than conventional devices, while still achieving desired porosity. In particular, the device may achieve the desired porosity only at discrete sections along the length of the device where such a porosity is required (e.g., sections that will block the neck of the aneurysm upon deployment). The remaining sections of the device can be configured to increase the device's compliance. For example, the remaining sections can be formed from less material than the sections with the desired porosity. In some instances, the sections with the desired porosity are formed from mesh-screen segments and the remaining sections are formed from coil segments. In some instances, the mesh-screen segments are configured to further enhance the device's compliance. For example, the mesh-screen segment can be formed from a layered structure that achieves greater compliance than conventional braided structures.Type: ApplicationFiled: August 10, 2018Publication date: February 21, 2019Inventors: Armando Garza, Be Thi Le, Tae Hee Cho, Regina Coeli Velasco
