Abstract
Transcatheterly implantable mammalian body conduit intralumenal device and lumen wall anchor assembly. Anchor includes: wire network, connector positioning wires having a secured and a released position, and a connector disposed at end of each wire. Anchor has: a compact-secured-configuration, an expanded-secured-configuration, an expanded-released-configuration. When the anchor is in the expanded-secured-configuration, the wire network exerts a force on conduit lumen wall and the connector positioning wires are the in secured position. When the anchor is in the expanded-released-configuration, the connector positioning wires are in the released position, and do not obstruct fluid flow axially through conduit. Device includes an interconnector that allows for the releasable interconnector of the connectors thereto. Device and anchor assembly can be explanted from the conduit. Or, device can be released from the anchor at the implantation site and only the device explanted with the anchor remaining within the conduit.
Core Innovation
The invention relates to methods for explanting a blood pump from a body conduit. A blood pump is removably coupled to an anchor that is anchored to a wall of the body conduit at a delivery site, and decoupling causes the anchor to transition from a partially-expanded, secured configuration to an expanded, released configuration.
In the partially-expanded, secured configuration, a first portion of the anchor contacts the wall of the body conduit and a second portion of the anchor is secured to contacting the blood pump. In the expanded, released configuration, the second portion of the anchor is unsecured from the blood pump.
The method then removes the blood pump from the body conduit while the anchor remains anchored to the wall of the body conduit at the delivery site. The disclosed workflow includes decoupling while the anchor transitions through secured-to-released states and then performing removal such that only the blood pump is removed while leaving the anchor in place.
Claims Coverage
The supplied claims coverage identifies one independent claim directed to decoupling an anchored blood pump so the anchor transitions from a partially-expanded, secured configuration to an expanded, released configuration, followed by removing the blood pump while leaving the anchor anchored.
Decoupling an anchored blood pump by transitioning the anchor configuration
Decoupling the blood pump from an anchor that is anchored to a wall of the body conduit at a delivery site such that the anchor transitions from a partially-expanded, secured configuration, in which a first portion of the anchor contacts the wall of the body conduit and a second portion of the anchor is secured to contacting the blood pump, to an expanded, released configuration in which the second portion of the anchor is unsecured from the blood pump.
Removing the blood pump while leaving the anchor anchored to the delivery site
With the anchor anchored to the wall of the body conduit at the delivery site, removing the blood pump from the body conduit, thereby leaving the anchor anchored to the wall of the body conduit at the delivery site.
The core claim coverage centers on decoupling a blood pump from a wall-anchored anchor to change the anchor from partially-expanded and pump-secured to expanded and pump-released, followed by removing the blood pump while leaving the anchor anchored at the delivery site.
Stated Advantages
Enables explanting an anchored blood pump by transitioning the anchor to an expanded, released configuration where the second portion of the anchor is unsecured from the blood pump.
Allows removal of the blood pump while leaving the anchor anchored to the wall of the body conduit at the delivery site.
Allows device removal such that the anchor is left anchored to the wall of the body conduit at the delivery site.
Documented Applications
Explanting an anchored blood pump from a body conduit at a delivery site while decoupling the blood pump from a wall-anchored anchor and leaving the anchor anchored to the wall.
