  • Patent number: 11399969
    Abstract: A stent delivery system includes a handle and an elongate catheter extending from the handle. The elongate catheter includes an inner member, an outer member mounted about the inner member and adapted for longitudinal movement relative to the inner member from an extended position to a retracted position and a stent mounted about the inner member. The stent delivery system also includes a thumbwheel mounted to the handle. The thumbwheel is adapted for rotational movement to cause corresponding movement of the outer member from the extended position to the retracted position. In some examples, the stent delivery system may include a lock member adapted to engage at least one of the outer member and the thumbwheel to prevent movement thereof when the lock member is secured relative to the handle.

  • Patent number: 11395697
    Abstract: The disclosure relates to methods, systems and devices for severing and optionally removing at least a portion of heart valve leaflets. Leaflets can be partially removed or entirely removed or otherwise, the leaflets can be severed or splayed in such a way as to avoid coronary blockage, LVOT obstruction, or access challenges in procedures where a prosthetic valve is to be implanted within a previously implanted prosthetic valve. The disclosure also relates to numerous devices for and methods of disabling one or more valve ligating devices to provide an unobstructed valve opening so that a prosthetic heart valve can be implanted within the opening. The ligation device(s) is disabled either by removing the ligation device(s) or severing one leaflet so that ligated leaflets can be separated. In some embodiments, the ligation device(s) are severed to disable the ligation device(s).

  • Patent number: 10529097
    Abstract: In a method and apparatus for generating a three-dimensional multi-slice data set of a heart, a first image sequence with a number of two-dimensional images is acquired in a first slice of the heart during a duration of at least one heartbeat interval, and a second image sequence with a number of two-dimensional images is acquired in a second slice of the heart during the duration of a number of heartbeat intervals. The second image sequence is excised by selecting the two-dimensional images thereof that lie in a heartbeat interval closest to the duration of the heartbeat interval in the first slice. The three-dimensional multi-slice data set is generated by combining the first image sequence and the excised second image sequence.

  • Patent number: 10363392
    Abstract: Described herein are devices and methods for guide catheters having one or more regions of increased flexibility. A flexibility region comprises one tubular segment of the guide catheter with a non-linear seam between two non-concentric layers of material having different durometers. A non-linear seam, such as a zig-zag or sinusoidal configuration, permits controlled compression of lower durometer material between portions of higher durometer material.

  • Patent number: 10335018
    Abstract: An actuating member for making a flexible elongate member for medical use perform a predetermined action. The actuating member includes a push/pull member, an operating member, and a cam member. The push/pull member includes a first moving portion and a second moving portion, which are movable relative to each other. The push/pull member is pushed/pulled in conjunction with a movement of the first moving portion and the second moving portion. The operating member is rotatable about an axis in a direction intersecting an axial direction of the elongate member. The cam member moves the first moving portion and the second moving portion in conjunction with rotation of the operating member. The push/pull member makes the elongate member perform at least one of (i) an advance/retraction action and (ii) a bending action by transmitting the movement of the first moving portion and the second moving portion to the elongate member.

  • Patent number: 10328243
    Abstract: An improved system and method for placing implantable medical devices (IMDs) such as leads within the coronary sinus and branch veins is disclosed. In one embodiment, a slittable delivery sheath and a method of using the sheath are provided. The sheath includes a slittable hub, and a substantially straight body defining an inner lumen. The body comprises a shaft section and a distal section that is distal to, and softer than, the shaft section. A slittable braid extends adjacent to at least a portion of one of the shaft section and the distal section. In one embodiment of the invention, the sheath further includes a transition section that is distal to the shaft section, and proximal to the distal section. The transition section is softer than the shaft section, but stiffer than the distal section.

  • Patent number: 10300286
    Abstract: A tool has an outer assembly, which includes a deployment tube, extending around, and moveable with respect to an inner assembly of the tool; the inner assembly includes a single pull wire and a distal member configured to engage an end of an implantable medical device. The deployment tube includes an articulating segment located just proximal to an enlarged distal-most portion, which contains the device and the distal member. Relatively soft and stiff sections of a composite sidewall define the articulating segment and extend alongside one another, such that, when the pull wire is actuated, the composite sidewall causes bending of the segment in two directions. A handle assembly of the tool includes a control member for the pull wire, and may further include a flushing subassembly that has a connector port located at an end of the handle assembly that is opposite a proximal port of the handle.

  • Patent number: 10292820
    Abstract: A delivery device for a collapsible prosthetic heart valve may include an operating handle and a catheter assembly. The handle may include a housing, a piston cylinder, a piston longitudinally slidable within the piston cylinder, the piston and the piston cylinder together defining at least one pressure chamber, a deployment actuator coupled to the housing and rotatable relative thereto, and a pneumatic switch adapted to provide a pressurized fluid to the pressure chamber to apply a longitudinal force to the piston. The catheter assembly may include a first shaft around which a valve-receiving compartment is defined, the first shaft being operatively connected to the housing, and a distal sheath operatively connected to the piston, the distal sheath being moveable between a closed condition covering the compartment and an open condition uncovering the compartment. Longitudinal movement of the piston may move the distal sheath between the closed and open conditions.
