The invention relates in some aspects to a device for use in anchoring an implant, including anchors, sutures, implants, clips, tools, lassos, and methods of anchoring among other methods. Anchors as disclosed herein could be utilized to secure a coaptation assistance device, an annuloplasty ring, an artificial valve, cardiac patch, sensor, pacemaker, or other implants. The implant could be a mitral valve ring or artificial mitral valve in some embodiments.

Systems and methods for anchoring an implant

A method of performing a neurovascular procedure includes providing an assembly including a guidewire having a guidewire hub, an access catheter having an access catheter hub, and a guide catheter having a guide catheter hub. The method includes coupling the guidewire hub to a first hub adapter, coupling the access catheter hub to a second hub adapter, and coupling the guide catheter hub to a third hub adapter. Each of the first hub adapter, the second hub adapter and the third hub adapter is movably carried by a support table. The method includes driving the assembly in response to movement of each of the first hub adapter, the second hub adapter and the third hub adapter along the support table until the assembly is positioned to achieve supra-aortic vessel access.

Method of performing a multi catheter robotic neurovascular procedure

A method of priming an interventional device assembly includes providing the interventional device assembly including a first interventional device coupled to a first hub and a second interventional device coupled to a second hub arranged in a concentric stack, the second interventional device being positioned within a lumen of the first interventional device. The method includes coupling the interventional device assembly to a drive system while arranged in the concentric stack, axially advancing the first interventional device and the first hub relative to the second hub to decrease a depth of insertion of the second interventional device within the lumen of the first interventional device while maintaining a distal end of the second interventional device within the lumen of the first interventional device, and flushing the first interventional device with fluid after decreasing the depth of insertion of the second interventional device within the lumen of the first interventional device.

Method of priming concentrically stacked interventional devices

A method of priming an interventional device assembly includes providing the interventional device assembly, the interventional device assembly including a first interventional device and a second interventional device, the second interventional device being positioned within the first interventional device. The method further includes reciprocally moving at least one of the first interventional device and the second interventional device relative to the other of the first interventional device and the second interventional device while flushing a lumen between the first interventional device and the second interventional device with fluid to remove microbubbles from the lumen.

Method of priming an interventional device assembly

A robotic drive system includes a drive table having a main body and an extendable member configured to be at least partially received within the main body and being extendable from an end of the main body. One or more hub adapters are coupled with the drive table and are configured to couple to a corresponding hub so that axial movement of the one or more hub adapters drives the corresponding hub.

Telescoping drive table

A biostimulator, such as a leadless cardiac pacemaker, including a fixation element to engage tissue and one or more backstop elements to resist back-out from the tissue, is described. The fixation element can be mounted on a housing of the biostimulator such that a helix of the fixation element extends distally to a leading point. The leading point can be located on a distal face of the helix at a position that is proximal from a center of the distal face. The backstop elements can include non-metallic filaments, such as sutures, or can include a pinch point of the biostimulator. The backstop features can grip the tissue to prevent unscrewing of the fixation element. Other embodiments are also described and claimed.

Biostimulator having fixation element

A drive system for achieving supra-aortic access and neurovascular treatment site access includes a guidewire hub configured to adjust an axial position and a rotational position of a guidewire, a procedure catheter hub configured to adjust an axial position and a rotational position of a procedure catheter, a guide catheter hub configured to adjust an axial position of a guide catheter, and an access catheter hub configured to adjust an axial position and a rotational position of an access catheter, the access catheter further configured to laterally deflect a distal deflection zone of the access catheter.

Robotic drive system for achieving supra-aortic access

A fluidics management system includes a cassette configured to receive saline from a saline source, receive contrast from a contrast source, and receive vacuum from a vacuum source. The cassette includes a plurality of saline connectors, each of the plurality of saline connectors configured to couple to one of a plurality of catheters to provide saline thereto, a plurality of contrast connectors, each of the plurality of contrast connectors configured to couple to one of the plurality of catheters to provide contrast thereto, and a plurality of vacuum connectors, each of the plurality of vacuum connectors configured to couple to one of the plurality of catheters to provide vacuum thereto.

Fluidics management system

A biostimulator, such as a leadless cardiac pacemaker, having a patch antenna integrated into a housing, is described. The housing includes an annular wall that contains electronic circuitry of the biostimulator and provides a ground plane of the antenna. The patch antenna includes a meandering trace embedded in a curved dielectric layer that is mounted on the annular wall. The trace provides a conductor of the antenna and the dielectric layer provides a dielectric substrate of the antenna between the conductor and the ground plane. The electronic circuitry contained within the annular wall is electrically connected to the trace via an electrical feedthrough that passes through the annular wall and the dielectric layer. The electrical feedthrough places the electronic circuitry in communication with the antenna to transmit or receive wireless communication signals from an external device. Other embodiments are also described and claimed.

Biostimulator having patch antenna

A biostimulator, such as a leadless cardiac pacemaker, including a fixation element that can be locked to a helix mount, is described. The fixation element includes a fastener that engages a keeper of the helix mount. When engaged with the keeper, the fastener locks the fixation element to the helix mount. Accordingly, the fixation element does not move relative to the helix mount when the biostimulator is delivered into a target tissue. Other embodiments are also described and claimed.

Biostimulator having lockable fixation element

A leadless biostimulator including an attachment feature to facilitate precise manipulation during delivery or retrieval is described. The attachment feature can be monolithically formed from a rigid material, and includes a base, a button, and a stem interconnecting the base to the button. The stem is a single post having a transverse profile extending around a central axis. The transverse profile can be annular and can surround the central axis. The leadless biostimulator includes a battery assembly having a cell can that includes an end boss. A tether recess in the end boss is axially aligned with a face port in the button to receive tethers of a delivery or retrieval system through an inner lumen of the stem. The attachment feature can be mounted on and welded to the cell can at a thickened transition region around the end boss. Other embodiments are also described and claimed.

Leadless pacemaker having attachment feature

A leafless biostimulator, such as a leadless pacemaker, includes a housing sized and configured to be implanted within a heart of a patient and includes both primary and secondary fixation features. The primary fixation feature is adapted to rotate to fix the leadless biostimulator to a wall of the heart during initial implantation. Once the leadless biostimulator is implanted, the secondary fixation feature is adapted to resist counter-rotation of the leadless biostimulator. The primary fixation feature may include a fixation helix configured to affix the housing to the heart by rotating in a screwing direction. The secondary fixation feature may include an apex to engage the heart to resist unscrewing of the primary fixation feature.
