A system, device and method for left atrial appendage occlusion detection is disclosed. The system for occlusion detection comprises a sheath; a delivery system comprising: a delivery catheter extending between a proximal end and a distal end; and a handle coupled to the proximal end of the delivery catheter; a medical tool coupled to a distal end of the delivery catheter at a target location within a portion of an organ of a patient, the medical device comprising a hub including a bore defining an axis, an occluder portion coupled to the hub and an anchor portion extending between a first end and a second end; at least one pressure sensor configured to measure a pressure of the target cavity while blood is suctioned form inside the left atrial appendage; and at least one processor configured to process the pressure measurement acquired from the at least one pressure sensor.

Balloon catheters and methods are provided for selectively occluding blood flow into a right atrium of a patient's heart communicating with an inferior vena cava (IVC) and superior vena cava (SVC). In one embodiment, a catheter includes first and second balloons adjacent one another on a distal end of the catheter shaft. During use, the distal end is introduced into the right atrium and positioned such that the first balloon is located within the right atrium. The first balloon is expanded within the right atrium and the catheter shaft directed such that the expanded first balloon engages at least a portion of the IVC to prevent substantial inflow into the right atrium from the IVC. The second balloon is then expanded to limit inflow into the right atrium from the SVC, and a medical procedure is performed within the patient's body.

The cardiovascular device (1) comprises a diaphragm assembly designed to be inserted into a ventricular cavity (VS) substantially transverse in order to reduce its volume, said diaphragm assembly having a peripheral edge (2B) that can be sealingly engaged on the walls (5) of the cavity 7 and being alternately driven between an active blood thrust position and an inactive position, said assembly being at least partially deformable in response to contractions of the walls (5) and comprising a balloon-shaped elastic body (2; 100; 200; 300; 400) which has an external surface (2A; 103) that defines and encloses an internal cavity (CI; CI2) and which can be configured between a gathered position of minimum bulk, an everted position of maximum bulk and vice-versa, at least one mobile portion (3; 3′) of the peripheral surface which is disposed transverse/diagonal and which is surrounded by the peripheral edge and at least one aperture (3A) for access from the outside to the internal cavity (CI; CI2).

A device for use with a uterine tamponade balloon catheter apparatus, such as the Bakri postpartum hemorrhage balloon, is disclosed. The device comprises a stylet comprising a hub at its proximal end and an atraumatic tip at its distal end. The device is configured to be removably coupled to the tamponade balloon catheter apparatus to aid in the insertion and positioning of the tamponade balloon catheter within the uterine cavity, allowing the balloon to function as intended for the control and management of postpartum hemorrhage and uterine bleeding. The tamponade balloon catheter includes an echogenic element to aid in visualization by ultrasound during insertion and use. Methods of use of the device are also disclosed.

A medical device is disclosed and may have a spiral shape structure that can function as a stent, such as a flow diversion stent to treat aneurysms. The medical device may have a spiral shape structure that can function as an occlusive device, for instance to occlude aneurysms. The medical device may include a shape setting structure to selectively adjust the shape of the medical device.

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 disclosed technology provide flow diverting devices for dialysis vascular access, and methods for use therewith. According to some embodiments of the disclosed technologies, a medical device comprises: a tubular vascular stent; and a flow restrictor disposed within the tubular vascular stent. According to some embodiments of the disclosed technologies, a method comprises: providing a medical device, the medical device comprising: a tubular vascular stent, and a flow restrictor disposed within the tubular vascular stent; and deploying the medical device at a site within a vascular access of a patient. According to some embodiments of the disclosed technologies, a medical device comprises: a tubular vascular stent; one or more anchor struts formed on at least one end of the tubular stent; a flow restrictor disposed within the tubular vascular stent; and a tubular stent cover, wherein the vascular stent is disposed within the tubular stent cover.

An atrial appendage closure device is provided that includes an insertion rod having a first end and a second end. An occluding member having an outer surface and an inner surface is connected to the first end of the insertion rod. The occluding member is moveable between a retracted position and a deployed position such that, in the deployed position, the occluding member is configured to provide a seal between a left atrial appendage and a left atrium of a heart. An anchoring member is further connected to the insertion rod and is configured to slide along the insertion rod to secure the device to a wall of a left atrial appendage. Methods for occluding a left atrial appendage that make use of the closure devices are also provided.

This invention is an intrasacular aneurysm occlusion device with a longitudinal mesh ribbon having a series of loops or segments with distal-to-proximal variation in their sizes, shapes, or orientations. For example, loops or segments can be progressively smaller in size and/or progressively more curved as one views the series in a distal-to-proximal direction. The device may also enable a user to selectively and remotely bend, steer, or elongate the loops or segments in real time as the ribbon is being deployed into an aneurysm sac.
