Publication number: 20190091047Abstract: A stent is formed from an at least partially cylindrical non-bioresorbable framework with a longitudinal zone of the stent that extends from the proximal end of the framework to the distal end and is defined by opposing longitudinal edges. A plurality of bioresorbable struts are secured to opposing longitudinal edges of the longitudinal zone. The bioresorbable struts hold the opposing longitudinal edges a first distance apart at an expanded deployed diameter to apposition the framework against a wall defining the vessel. After the stent is endothelialized, degradation of the bioresorbable struts causes the stent to contract to a reduced deployed diameter so that the opposing longitudinal edges are a second distance apart that is less than the first distance.Type: ApplicationFiled: March 29, 2016Publication date: March 28, 2019Applicant: Cardinal Health Switzerland 515 GmbhInventor: Quentin Walsh

Publication number: 20190091049Abstract: A crimper device can facilitate sheathing of a stent frame for vascular delivery. The device can include first and second components that rotate relative to each other to drive radial movement of one or more compression members of the device. The one or more compression members can direct and balance a compressive force within an aperture of the device. In use, the stent frame can be positioned within the aperture and be compacted by actuation of the compression members.Type: ApplicationFiled: November 26, 2018Publication date: March 28, 2019Inventor: Brandon G. WALSH

Publication number: 20190091051Abstract: A deployment device for deploying an expandable endoluminal prosthesis within a body vessel may include an elongate member extending longitudinally along at least a portion of a length of the deployment device. The deployment device may include at least one engagement member coupled to the elongate member and extending outwardly from the elongate member. The deployment device may include a circumferential trigger wire extending at least partially circumferentially around the elongate member and removably received between the engagement member and the elongate member. The circumferential trigger wire may be manipulatable from a distal end of the deployment device, whereby the circumferential trigger wire is removable from between the engagement member and the elongate member.Type: ApplicationFiled: November 30, 2018Publication date: March 28, 2019Applicant: COOK MEDICAL TECHNOLOGIES LLCInventor: Blayne A.

Publication number: 20190091053Abstract: The present invention relates to a device for intermittently obstructing a bodily opening, such as a gastric opening, and includes a proximal member connected to a distal member by a tether. The proximal member includes an apron member surrounding a first occluding member, which is formable from an elongated and narrower configuration to a contracted or expanded but wider configuration. When employed in the stomach, the device of the present invention is arranged transluminally, with the distal member disposed in the duodenum and the proximal member disposed against the pyloric valve, intermittently occluding the pyloric valve and preventing or delaying the flow of gastric contents through the pyloric valve. In certain embodiments, a reservoir may be included for releasing a substance of interest, for example for releasing insulin from a reservoir disposed in the distal member. Sensors, actuators, and data transmission devices may also be included.Type: ApplicationFiled: October 11, 2018Publication date: March 28, 2019Applicant: BAROnova, Inc.Inventors: Daniel R.
