A medical implant for occluding a left atrial appendage may include an expandable framework configured to shift radially between a first configuration and a second configuration, and an occlusive element secured to the expandable framework. The framework includes a plurality of strut groups, each strut group comprising first and second joints, and first, second, and third struts. The first and second struts move laterally from a first position in the first configuration to a second position in the second configuration. The third strut is configured to shift radially from a first position in the first configuration to a second position in the second configuration. The first and second struts and a majority of the third struts of each strut group may be oriented parallel to each other in the first configuration and nonparallel to each other in the second configuration.

Medical device for occluding a left atrial appendage

An occlusive implant may include an expandable framework configured to shift between a collapsed configuration and an expanded configuration, the expandable framework including a proximal end and a distal end. The expandable framework includes a plurality of anchor members extending radially outward from the expandable framework in the expanded configuration, each anchor member including a root portion fixedly attached to the expandable framework and extending distally to a trunk portion in the expanded configuration. At least a portion of the trunk portion extends radially outward relative to the root portion in the expanded configuration. At least one of the plurality of anchor members includes a plurality of branches extending radially outward from the trunk portion in the expanded configuration.

Multi-sharpness split top soft tissue anchors

An implant includes a pair of anchors and a pair of anchor housing assemblies, wherein an anchor housing assembly includes an anchoring component configured to translate the anchor proximally-distally through the anchor housing assembly and a cinch component configured to control a space between the pair of anchor housing assemblies.

Simplified coaxial shaft design delivery system and implant for mitral valve annulus reduction

An example occlusive implant is disclosed. The example occlusive implant includes an expandable framework configured to shift between a first configuration and an expanded configuration and a fixation member disposed along the expandable framework. The fixation member includes a first engagement portion and an anchor portion. Further, the first engagement portion is designed to be secured to the expandable framework and the anchor portion extends away from an outer surface of the expandable framework.

Occlusive medical device

An occlusive implant system may include a catheter having a lumen extending from a proximal opening to a distal opening, a core wire slidably disposed within the lumen, and an occlusive implant having an expandable framework configured to shift between a collapsed configuration and an expanded configuration, and an occlusive element disposed on the expandable framework. The expandable framework may include a plurality of anchor members extending radially outward from the expandable framework, at least some of the plurality of anchor members each have a barb projecting circumferentially therefrom. The occlusive implant may be releasably connected to a distal portion of the core wire.

Occlusive medical device with fabric retention barb

Example medical devices and methods of making example medical devices are disclosed. An example medical device includes a frame configured to be secured to cardiac tissue, wherein the frame includes a fatigue resistant nickel-titanium alloy that is heat set at a temp in the range of 450-550 degrees Celsius.

Medical devices having increased fatigue resistance

An example occlusive implant is disclosed. The example occlusive implant includes an expandable framework configured to shift between a collapsed configuration and an expanded configuration, wherein the expandable framework includes a plurality of strut members circumferentially spaced around a longitudinal axis of the expandable framework, wherein one or more of the plurality of strut members includes a first twisted portion and a face portion. The occlusive implant also includes a plurality of fixation members disposed along the face portion of one or more of the plurality of strut members.

Occlusive medical device with fixation members

Solutions for reducing irritation and/or trauma which may result upon contact of an implanted implantable device with tissue surrounding or adjacent to the implantable device. Various embodiments include features which allow a tangential or otherwise atraumatic contact of the implantable device with the tissue, in contrast with a sharper contact which may occur with prior art implantable devices. The broad principles are applicable to annuloplasty devices, and have other broader applications as well.

Atraumatic components and structures for implantable devices

An implant for occluding a left atrial appendage may include an expandable framework configured to shift between a collapsed configuration and an expanded configuration, wherein the expandable framework includes an attachment point configured to secure the expandable framework to a delivery device, and an occlusive element disposed on a proximal portion of the expandable framework, wherein the occlusive element covers the attachment point.

Left atrial appendage implant with continuous covering

An example medical device for occluding the left atrial appendage is disclosed. The example medical device for occluding the left atrial appendage includes an expandable member having a first end region, a second end region and an inflation cavity. The example medical device includes at least one fixation member having a first end and a second end coupled to the expandable member. The at least one fixation member is configured to move from a delivery configuration to a deployed configuration in response to an expansion of the expandable member. Additionally, the example medical device includes a valve member extending at least partially into the inflation cavity and the expandable member is configured to expand and seal the opening of the left atrial appendage.

Occlusive device with actuatable fixation members

An actuator sleeve includes resiliency features that may reduce chronic strain on valve annulus implants. The resiliency features may relate to one or more of a material, a manufacture, a dimension, and/or design attribute of the sleeve. In one aspect the resiliency features may allow deformation of the sleeve at frame interfaces to distribute forces to reduce the frame fatigue.

Strain-relieving sleeve for cardiovascular devices

Anchoring assemblies that increase the surface area and/or amount of anchored tissue include a barb anchor, translatably disposed within the opening of an anchor housing, the barb anchor comprising a barb arm, the barb arm including a linear configuration wherein the barb arm is aligned with an axis of the opening and a deflected configuration wherein at least a portion the barb arm is deflected away from a central axis of the opening of the anchor housing.

Coil and barb anchors for heart valve repair devices

An example occlusive implant is disclosed. The example occlusive implant includes an expandable framework configured to shift between a first configuration and a second expanded configuration, an occlusive member disposed along at least a portion of an outer surface of the expandable framework and a resilient member coupled to the occlusive member. Further, the resilient member is configured to keep the occlusive member taut against an outer surface of the expandable member in both the first configuration and the second configuration.

Medical device with occlusive member

An implant includes a frame comprising a tubular body formed by a plurality of interconnected struts that are manufactured to reduce stresses and strains resulting from component interaction during chronic use. At least a portion of a longitudinal corner of one or more struts of the frame may be chamfered, rounded, or otherwise modified to distribute stresses experienced at the strut corner throughout the strut body. Chamfering and/or rounding corners along at least a portion of a strut of the frame may reduce stresses on the frame caused by interactions between the frame and other components of the implant. The implant may be manufactured by cutting (e.g., laser cutting) a plurality of struts from a tubular metal alloy, polymer, or the like forming the tubular body, and softening at least a portion of an edge of the strut by cutting, grinding, and/or micro-blasting the edges of the corner.
