PROSTHETIC VALVE WITH NATURAL BLOOD FLOW

A prosthetic valve may be formed to direct flow out of the outflow orifice toward a posterior portion of a heart wall. The prosthetic valve includes an expandable frame which may be covered with a cover that is suturelessly attached to the frame. The prosthetic valve may also include an outflow orifice size which is controlled. Methods of using these devices are also disclosed.

Devices and methods for controlled delivery of a stent

The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to devices and methods for controlled delivery of a stent, such as a self-expanding stent, and more particularly for controlling the full deployment of a stent in incremental steps from a sheath and for controlling the reconstrainment of a stent in incremental steps within a sheath.

Urological implant having extraction handle and/or arched members
11571290 · 2023-02-07 ·

Embodiments of a Urological implant include an implant with an elongated body having a longitudinal axis. Optionally longitudinal ribs symmetrically oppose each other and are connected to elongated body. The longitudinal ribs are optionally elastically shiftable between a collapsed state and an expanded state relative to the spinal longitudinal axis, in order to retract or/and support periurethral tissue. Optionally the system includes an implant extraction handle. The extraction handle is optionally positioned proximally to the elongated body and connected to the longitudinal rib and subject to a pulling force to facilitate and/or force approximation of the longitudinal supports to the longitudinal axis. In some embodiments, an implant body includes longitudinally spaced arched members, interconnected via arch ends sequentially along a length of a first and second longitudinal rib. Optionally the arched members are elastically bendable to facilitate elastic contractibility of the implant body under a transverse compressive force.

STIFF BRAID MEMBER FOR PROSTHETIC VALVE DELIVERY APPARATUS

A braided member can include a first set of yarns extending in a first direction, a second set of yarns extending in a second direction and intertwined with the first set of yarns, and a set of axial yarns extending along a longitudinal axis of the braided member and disposed between the first set of yarns and the second set of yarns. The braided member can include a tubular braid.

MEDICAL IMPLANT DELIVERY SYSTEM AND RELATED METHODS

An implant delivery system including a fixation member delivery system including an elongate shaft, first and second rails, a plurality of fixation members with each fixation member slidably disposed on the first and second rails and an actuation assembly. The actuation assembly includes a first elongate member including a first plurality of engagement members disposed along the first elongate member with a distal end region of each engagement member in engagement with one of the fixation members, a second elongate member including a second plurality of engagement members disposed along the second elongate member with a distal end region of each engagement member in engagement with one of the fixation members. Additionally, cyclical actuation of the actuation assembly is configured to incrementally move the fixation members distally along the first and second rails to deploy each of the plurality of fixation members in sequence.

INVERSION DELIVERY DEVICE AND METHOD FOR A PROSTHESIS

A delivery device usable to deliver an inverting implant is provided that includes a positioning mechanism that automatically initiates the inversion process once a predetermined length of the implant has exited a delivery catheter. The positioning mechanism allows the implant to be safely and accurately deployed with reduced operator experience and in a greater variety of target locations.

DELIVERY SYSTEM FOR DELIVERING AN ENDOVASCULAR GRAFT WITHIN A BLOOD VESSEL
20230030051 · 2023-02-02 ·

A delivery system for delivering an endovascular graft within a blood vessel. The delivery system includes a tip assembly including a tip and a sleeve having a proximal end. The delivery system includes a tip capture mechanism. The tip assembly is configured to move axially relative to the tip capture mechanism and between a delivery position and a release position. The tip capture mechanism includes a landing zone. The delivery system includes a travel limiter configured to align the proximal end with the landing zone when the tip assembly is in the release position to facilitate removal of the delivery system from the blood vessel.

Systems and methods for delivering implantable devices across an atrial septum

Systems and methods for delivering a device for regulating blood pressure between a patient's left atrium and right atrium are provided. The delivery apparatus may include a first catheter, a hub having one or more engagers disposed thereon configured to releasably engage with a first expandable end of the shunt in a contracted delivery state within a lumen of a sheath, and a second catheter extending through a center lumen of the first catheter and the hub, wherein the first catheter, the hub, and the second catheter are independently moveable relative to the sheath. The inventive devices may reduce left atrial pressure and left ventricular end diastolic pressure, and may increase cardiac output, increase ejection fraction, relieve pulmonary congestion, and lower pulmonary artery pressure, among other benefits. The inventive devices may be used, for example, to treat subjects having heart failure, pulmonary congestion, or myocardial infarction, among other pathologies.
