Patent number: 10426617Abstract: A replacement heart valve locking mechanism may include a buckle member fixedly attached to a tubular anchor member defining a central longitudinal axis, a post member axially translatable relative to the buckle member, and an actuator member releasably connected to the post member at an attachment point. The post member may include a latch portion configured to engage a catch formed in the buckle member such that movement of the post member distally relative to the buckle member is prevented. The attachment point may be disposed proximal of the latch portion. Circumferential translation of the latch portion about the central longitudinal axis may disengage the latch portion from the catch.Type: GrantFiled: March 2, 2016Date of Patent: October 1, 2019Assignee: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Andrew J.

Patent number: 10213299Abstract: Medical devices and methods for making and using medical devices are disclosed. An example medical device may include an inner shaft having a distal end region. A valve implant may be releasably coupled to the distal end region. The valve implant may be capable of shifting between an elongated configuration and an expanded configuration. A post assembly may be disposed along the valve implant. The post assembly may include a release member that is axially slidable along the post assembly. The medical device may also include a rod designed to engage the release member. The rod may be designed to shift the valve implant between the elongated configuration and the expanded configuration. Axially shifting the release member along the post assembly may release the rod from the post assembly and deploy the valve implant.Type: GrantFiled: July 22, 2016Date of Patent: February 26, 2019Assignee: BOSTON SCIENTIFIC SCIMED INC.Inventors: Andrew J.

Patent number: 10195392Abstract: A medical device may include a device handle having a diverter block non-movably disposed within an interior cavity of the handle, the diverter block including at least one lumen extending longitudinally therethrough and a distal mounting portion. A delivery sheath may be coupled to the device handle. A catheter assembly may extend distally from the device handle within the delivery sheath. The catheter assembly may include a multi-lumen polymeric shaft coupled to the diverter block, and a metallic hypotube section disposed about and fixedly attached to a proximal end of the shaft. The hypotube section may releasably lock the shaft to the diverter block in fluid communication with the at least one lumen of the diverter block. The delivery sheath may be axially translatable relative to the device handle and the catheter assembly may be fixed in position relative to the device handle.Type: GrantFiled: June 30, 2016Date of Patent: February 5, 2019Assignee: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Crissly V.
