Disclosed are a puncture sealing device and methods of locating a puncture site within a vessel. The systems can include elongated dilators and access sheaths that are configured to locate the puncture site within a vessel so that the position of the puncture site relative to a distal end of the access sheath is known during a puncture sealing procedure.

A bleeding control device for mitigating bleeding includes an outer storage container housing, a compressed gas canister, wound blocking contents and a control element. The bleeding control device may be used to deliver variable contents to a wound at the site of injury to control the bleeding of a victim as temporary solution for mitigating the bleeding until more advanced medical care can be provided. A bleeding control device includes a canister housing, a compressed gas canister arranged within the canister housing, a tube connected to the canister housing, an inflatable balloon disposed on the tube, the inflatable balloon being fluidly connected to the compressed gas canister, and a control element configured to activate the compressed gas canister to inflate the inflatable balloon.

The present disclosure relates to an occluder pushing device and an occluder delivery system, wherein the pushing device includes a pushing component and a handle. The pushing component includes a pushing tube and a traction element slidably inserted into the pushing tube. The handle is fixedly connected to a proximal end of the pushing tube and internally provided with a moving component and a locking component. The moving component includes a translation mechanism and a rotation mechanism, where the translation mechanism is used to drive the traction element to move axially inside the pushing tube, and the rotation mechanism is used to drive the traction element to rotate axially inside the pushing tube. The locking component is used to lock relative positions of the traction element and the pushing tube, and the rotation mechanism includes a locking structure for locking or releasing linkage between the rotation mechanism and the traction element. The pushing device of the present invention has provided therein the locking component for locking the traction element and the pushing tube in relative positions, such that when the pushing tube pushes the occluder, the relative positions of the traction element and the pushing tube lock the occluder in a folded state, thereby preventing the occluder from being prematurely released before reaching a pre-determined position.

Embodiments of the present invention provide an improved vascular occlusion device for occlusion of a passageway, cavity, or the like. According to one embodiment, a medical device for occluding a left atrial appendage is provided. The medical device includes a first portion having at least one plane of occlusion that is configured to be positioned outside of the left atrial appendage, and a second portion having at least one plane of occlusion that is configured to be at least partially positioned within a cavity defined by the left atrial appendage.

A method for closure of the left atrial appendage (LAA), including: placing an LAA reshaper in contact with an LAA wall or near the LAA wall; invaginating at least a portion of the LAA into the left atrium (LA); reshaping by the LAA reshaper the LAA during the invagination; fastening the invaginated at least a portion of said LAA; and retracting the LAA reshaper from the LAA

A drive mechanism for operating a suturing mechanism includes a user input displaceable through a range of motion and a linkage mechanically associated with the user input and with a shuttle transmitter of the suturing mechanism. The linkage converts displacements of the user input unidirectionally or bidirectionally into a sequence of operations of the shuttle transmitter including sufficient to perform a sequence of operations of the suturing mechanism to perform successive bidirectional stitching, with the shuttle transmitter penetrating tissue alternately with and without a shuttle needle attached.

The invention relates to a sealing device for repair of cardiac and vascular defects or tissue opening such as a patent foramen ovale (PFO) or shunt in the heart, the vascular system, etc. and particularly provides an occluder device and trans-catheter occluder delivery system. The sealing device would have improved conformity to heart anatomy and be easily deployed, repositioned, and retrieved at the opening site.

An adhesive pad for use with a hemostasis device comprising a footplate having a top surface and a receiving device positioned on the footplate, the adhesive pad comprising: (1) a flexible backing layer having a bottom surface, a central portion having an opening, a first side portion, and a second side portion; (2) an adhesive layer applied to the bottom surface of the backing layer; and (3) a release layer removably secured to the adhesive layer. The opening in the central portion of the backing layer is sized to fit the receiving device of the hemostasis device, and the adhesive layer applied to the bottom surface of the first and second side portions of the backing layer is configured to adhere to and extend beyond the top surface of the footplate.

A delivery device includes an inner shaft, an outer sheath, a nosecone, and a tether component. The outer sheath is slidably disposed over the inner shaft. The nosecone is removably coupled to the inner shaft. The nosecone includes a delivery configuration for delivery to a treatment site, a radially compressed configuration in which a portion of the nosecone is configured to traverse through a heart wall, and a radially expanded configuration in which an outer surface of the nosecone contacts an outer surface of the heart wall. The tether component includes a first end coupled to the nosecone. The nosecone is configured to plug a piercing in the heart wall when in the radially expanded configuration.

An intravascular delivery device is disclosed comprising a delivery wire having a proximal and a distal end and an interior lumen extending there between and wherein said distal end comprises a connection interface adapted to matingly interlock with a proximal end portion of a medical implantable device, wherein said delivery device comprises a locking unit arranged to secure said connection interface in a locking position in which said medical implant is pivotably locked before a controlled release.
