Multistage bioabsorbable plug system and method of insertion
11083464 · 2021-08-10 · ·

A system and method for sealing openings in a body of a patient made by a medical procedure or non-medical event. The opening may be formed in soft tissue, internal organs, or hard tissue. A coaxial needle is inserted into a patient and a coagulating agent is inserted into the patient via the coaxial needle. The coagulating agent is discharged adjacent to the opening and the coaxial needle is inserted to a surgical depth. Following the procedure, the coaxial needle is retracted to a plug discharging depth. A bioabsorbable plug in at least a partially dehydrated state is then discharged from the coaxial needle and the coaxial needle is removed. The plug resides at least partially within the opening in the organ or tissue created by the coaxial needle. The combination of the coagulating agent and the expandable plug seals the opening created by the coaxial needle.

Aneurysm Neck Bridge with a Closeable Opening or Lumen Through Which Embolic Material is Inserted into the Aneurysm Sac
20210236139 · 2021-08-05 · ·

This intrasacular aneurysm occlusion device includes a neck bridge with a closeable opening through which embolic material is inserted into an aneurysm sac. After the neck bridge has been expanded within the aneurysm sac, a catheter is inserted through the opening and embolic material is delivered through the catheter into the aneurysm sac. After the aneurysm sac has been filled with embolic material, the catheter is then withdrawn and the opening is closed so that embolic material does not escape out of the aneurysm sac.

Occlusive medical device

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, an occlusive member disposed along at least a portion of the expandable framework and a sealing member disposed along the occlusive member, wherein the occlusive member includes at least a first cellular tissue growth pathway.

METHODS, COMPOSITIONS, AND DEVICES FOR THE OCCLUSION OF CAVITIES AND PASSAGEWAYS

Provided herein are methods, compositions, and devices for occluding cavities or passageways in a patient, in particular cavities or passageways in the cardiovascular system of a patient, such as the LAA of a patient's heart. The methods, compositions, and devices can be used to percutaneously occlude the LAA, decreasing the risk of thromboembolic events associated with AF.

APPARATUS, SYSTEMS, AND METHODS TO IMPROVE ATRIAL FIBRILLATION OUTCOMES INVOLVING THE LEFT ATRIAL APPENDAGE

Apparatus, systems, and methods are provided for monitoring AF episodes, delivering ATP pulses, and/or achieving electrical isolation of the left atrial appendage (LAA) of a patient's heart and/or preventing thrombus formation after electrical isolation. For example, devices are provided that may implanted from within the left atrium, e.g., to isolate the LAA, prevent thrombus formation within the LAA, facilitate endothelialization, and/or deliver pacing.

Devices and methods for excluding the left atrial appendage

Systems, devices and methods for occluding the left atrial appendage (LAA). The device excludes the LAA from blood flow. The implantable device is delivered via transcatheter delivery into the LAA and secured within the LAA. The implant comprises an expandable and compliant frame and an expandable and conformable tubular foam body. A delivery and tether retraction system includes a handle for controlling a pusher and tether. The pusher may be moved a distance away from the implant without changing the orientation of the implant, while the tether is still attached to the implant. Severing the tether and proximally retracting a control on the hand piece by a distance causes the severed end to advance distally by at least about twice that distance. A loader includes a conical portion with guides and a reservoir for submerging the foam prior to loading and delivery.

MEDICAL SYSTEMS, DEVICES, AND RELATED METHODS

A medical system includes a source of a material, a first tube, and a second tube. The material is configured to expand and form a porous body after the material is deployed into a body lumen. The first tube is configured to deliver the material into the body lumen, and the second tube is configured to apply suction to the porous body.

DEVICES AND METHODS FOR EXCLUDING THE LEFT ATRIAL APPENDAGE

Systems, devices and methods for occluding the left atrial appendage (LAA). The device excludes the LAA from blood flow. The implantable device is delivered via transcatheter delivery into the LAA and secured within the LAA. The implant comprises an expandable and compliant frame having anchors and an expandable and conformable tubular foam body. A delivery and tether retraction system includes a handle for controlling a pusher and tether. The pusher may be moved a distance away from the implant without changing the orientation of the implant, while the tether is still attached to the implant. A loader includes a conical portion with guides and a reservoir for submerging the foam implant prior to loading and delivery.

Devices and methods for treating fistulae and other bodily openings and passageways

Some aspects of the present invention are directed to unique products and methods for treating fistulae and other passageways and openings in the body. In some preferred forms, an inventive construct will include an elongate graft body that incorporates a plurality of sheet or sheet-like segments. The plurality of sheet or sheet-like segments, in some arrangements, will be stacked in a generally longitudinal direction along the length of the plug body, and optionally, the segments will be received over one or more elongate elements. Elongate elements of this sort can take a variety of forms including a suture, wire, filament, or other relatively thin-bodied elongate member, although in some forms, an elongate element will be or include a somewhat heftier structure such as a biodegradable or non-biodegradable three-dimensional body.

Devices and methods for excluding the left atrial appendage

Devices and methods are described for occluding the left atrial appendage (LAA). The device excludes the LAA from blood flow to prevent blood from clotting within the LAA and subsequently embolizing, particularly in patients with atrial fibrillation. The implantable device is delivered via transcatheter delivery into the LAA and secured within the LAA. The implant comprises an expandable and compliant frame and an expandable and conformable tubular foam body carried by the frame. The device may have a thromboresistant cover at a proximal end and a thromboresistant coating on the foam body. The frame may have recapture struts inclining radially outwardly in the distal direction from a central hub. The frame may have axially extending side wall struts, with adjacent pairs of side wall struts joined at one or more apexes. Anchors extend from the frame to engage tissue. The anchors can also be reversible to allow retraction of the anchors and repositioning or retrieval of the device.
