Abstract: A handle assembly for controlling the implantable device includes an actuation element extending through a sheath, a paddle actuation control coupled to the actuation element, and a visual indicator. In some implementations, the handle further includes a paddle width adjustment element and a paddle width control that is actuatable to cause axial movement of the paddle width adjustment element, thereby causing a width of the at least one of the pair of paddles of the implantable device to be moved from a first width to a second width. In some implementations, the visual indicator is coupled to the actuation element or the paddle width adjustment element through the handle housing and is configured to provide an indication regarding a configuration of the implantable device.

Abstract: Delivery systems and methods of delivering devices or implants are disclosed. The devices or implants can be configured as valve repair devices or treatment devices have gripping members that are openable and closable to attach the device to leaflets of a native heart valve. The delivery systems are configured to position the device or implant and open and close the gripping members of the device or implant.

IPC: A61M25/00

Abstract: Devices and methods for selectively directing fluid flow through lumens of a catheter in order to effectively flush and/or de-air specified lumens of the catheter are disclosed. As one example, an assembly comprises a catheter including a first shaft and a second shaft extending through the first shaft. The assembly further comprises a sealing mechanism including a first seal disposed around a distal end portion of the first shaft, a second seal disposed around a portion of the second shaft that extends distal to the first shaft, and a cavity disposed within a housing of the sealing mechanism between the first seal and the second seal. A distal end of the first shaft is disposed within the cavity and the cavity is fluidly sealed by the first seal and the second seal such that fluid from a first lumen of the first shaft cannot exit the cavity.

Abstract: A system, for use with a leaflet of a valve of a subject's heart, comprises a catheter, a cutting device, a helical needle, and a suture. The catheter is transluminally advanceable toward the heart. The cutting device is advanceable distally out of the catheter, and is adapted to cut through tissue of the leaflet to form cut tissue and cut edges at the cardiac valve. The helical needle defines a helical lumen, the helical needle configured to be advanced distally out of the catheter and to rotationally extend through, and secure together, two tissue segments of the leaflet. The suture extends through the helical lumen of the helical needle. The helical needle and the suture are configured to extend along the two tissue segments of the leaflet to suture the two tissue segments to each other. Other embodiments are also described.

Abstract: Components for valve treatment systems are disclosed. Valve treatment systems can include a delivery system for an implantable device. The delivery system can include one or more of clasp control components slidably disposed on a catheter handle, a control element for opening and closing the implantable device, a catheter assembly with features to reduce friction with another catheter assembly, grips for attaching catheter assemblies to clamps, catheter assemblies with features that stiffen or provide variable stiffness, and catheter assemblies with one or more steering control lumens incorporated into a reinforcement layer.
