The invention is a device, system, and method for repairing heart valve function, which may include bisecting native valve leaflets for improved deployment of a prosthetic heart valve in the native valve annulus. The invention may include a catheter having a cutting element shaft with a cutting element configured to puncture a valve leaflet and/or make a controlled cut through the leaflet. The device may have an extendable foot configured to be positioned on an opposite side of the valve leaflet from the cutting element shaft. The device may include magnets to guide the cutting element and/or cutting element shaft in proper alignment with the extendable foot and to hold the elements in place during leaflet bisection.

A catheter according to an embodiment of the present disclosure includes a mesh member, a first hollow shaft, a front end tip, a guiding film, and a core wire. The mesh member has a tubular shape and is radially expandable and contractable. The guiding film is formed with a stretchable material and is disposed on the mesh member, the guiding film having a front end located between a base end of the front end tip and a front end of the first hollow shaft. A thickness of a base end of the guiding film is larger than a thickness of the front end of the guiding film.

Single filter and multi-filter endolumenal methods and systems for filtering fluids within the body. In some embodiments a blood filtering system captures and removes particulates dislodged or generated during a surgical procedure and circulating in a patient's vasculature. In some embodiments a filter system protects the cerebral vasculature during a cardiac valve repair or replacement procedure.

A method of deploying an implantable stented device in an anatomical location of a patient, including the steps of providing a delivery system with first and second stent engagement structures at its distal end, attaching a first structural element of the stented device to the first stent engagement structure and attaching a second structural element of the stented device to the second silent engagement structure, advancing the stented device to an implantation site, and sequentially disengaging the first structural element of the stented device from the first stent engagement structure of the delivery system and then disengaging the second structural element of the stented device from the second stent engagement structure.

Methods and apparatus for use in capturing embolic debris during a surgical procedure in a patient are provided. The methods include utilizing an embolic capture device that is configured for delivery into a patient via a transapical delivery approach and via an arterial delivery approach, and determining which of a transapical delivery approach and an arterial delivery approach should be used with the patient. The methods also include inserting the embolic capture device within a delivery system, and deploying the embolic capture device at a desired location within the patient's blood vessel that is downstream from the location of the surgical procedure. The same embolic capture device is configured for use with a transapical delivery approach and an arterial, such as a transfermoral, delivery approach.

Clot removal from a patient's vessel, such as an artery, are described using aspiration and hydraulic forces supporting the removal process. Hydraulic forces can be generated by occluding the vessel distal to the clot and delivering liquid between the clot and the occlusive device. The aspiration catheter is positioned proximal to the clot. Catheters designed to facilitate the delivery of hydraulic forces can be based on single lumen designs or dual lumen designs. The catheters may have a fixed internal wire, or in some embodiments the catheters can ride over a wire with a valve/seal positioned to restrict flow into or out from the guide lumen such that the guide lumen can further function for balloon inflation and/or for infusion of liquid.

Provided are medical devices, systems and methods for retrieval and/or extraction of a corpus located in a tubular organ. Systems of this disclosure are configured for carrying out various procedures for removal of occlusive corpus from tubular organs, for example thrombectomy.

A system for removing an obstruction from a blood vessel. The system can include a catheter with a proximal section with a proximal section lumen diameter and a distal section with a distal section lumen diameter less than the proximal section lumen diameter. The system can include a clot retrieval device with a clot engaging element. The system can include a shaft advanceable through the lumen of the catheter to the obstruction in the vessel. The shaft can include a shaft proximal section, a shaft distal section attached to the clot engaging element with a diameter less than that of the shaft proximal section and configured to cross the obstruction. The shaft proximal section diameter can be larger than the diameter of the distal section lumen diameter of the catheter, thereby inhibiting the shaft proximal section from distally advancing through the catheter distal section.

A design bringing together mechanical thrombectomy and stenting for more efficient treatment of occlusions and stenotic lesions in the cerebral vasculature features a dual-layer setup. The outer layer consists of an expandable stent cage with large cell openings which can allow thrombus to pass through the openings into the inner expandable capture section layer. The clot capture section can be configured to grip and extract the occlusion. The outer cage is configured to be detached from the remainder of the device and left implanted as a stent to exert an outward radial force to support and/or dilate the region of stenosis. The device can have a distal fragment protection element to prevent the distal migration of elements liberated during the procedure.

Funnel-trap type devices made of shape-set (e.g., heatset) braid for delivery and/or retrieval of Inferior Vena Cava (IVC) filters or other medical devices are described. Delivery and/or retrieval devices, kits in which they are included, methods of use and methods of manufacture are all contemplated herein.
