An intravascular device delivery system includes an elongated member with a distal end cap and a delivery disc that are longitudinally movable using a disc handle. A main body of the disc handle is configured to move the distal end cap and a movable body of the disc handle is configured to move the delivery disc. The movable body is movable relative to the main body, and the main body and movable body are movable together.

Systems and methods for loading and deploying an intravascular device

An intravascular device delivery system has an elongated member with a flexible hypotube. The hypotube can be rotationally keyed to a steerable catheter. The flexible hypotube includes one or more cuts to allow bending of the flexible hypotube within a first plane. The steerable catheter is steerable to bend the flexible hypotube within the first plane, and longitudinally movable relative to the flexible hypotube to allow distal movement of the steerable catheter relative to a distal end of the flexible hypotube.

Mechanical interlock for catheters

An intravascular device delivery system has an elongated member, a guidewire receiving member, and a distal cap longitudinally fixed to a guidewire receiving member. The distal cap includes an insert having an elongate member, a rim member radially separated from the elongate member, and a wall member supporting the rim member, the wall member being disposed between the rim member and the elongate member.

Insert for distal end cap

A medical device includes a scaffold crimped to a catheter having an expansion balloon. The scaffold is crimped to the balloon by a process that includes inflating the delivery balloon during a diameter reduction to improve scaffold retention and maintaining an inflated balloon during the diameter reduction and prior and subsequent dwell periods.

Methods for increasing a retention force between a polymeric scaffold and a delivery balloon

A steerable catheter has a body with an outer surface and an inner surface defining a central lumen. The outer surface and inner surface define a wall of the body, which has a plurality of steering lumen and control lumen extending longitudinally therethrough. The body includes a body material. The steering lumen and control lumen have a control lumen lining and steering lumen lining, respectively, with a higher durometer than the body material. A steering wire is positioned within the steering lumen and a control wire is positioned within the control lumen.

Combination steerable catheter and systems

The present disclosure describes devices, systems, and methods for intravascularly delivering an implantable device to a targeted anatomical site such as the mitral annulus. A delivery system includes a delivery member coupled to a handle assembly and extending distally from the handle assembly. A delivery catheter is concentrically positioned within an outer member and configured to advance the intravascular device relative to the outer member. The delivery catheter includes a distal can structure configured to house at least a portion of the intravascular device in a compressed, pre-deployed position.

Intravascular delivery system

The present disclosure describes devices, systems, and methods for loading, delivering, positioning, and deploying an artificial heart valve device at the mitral annulus. A delivery system includes a delivery member coupled to a handle assembly and extending distally from the handle assembly. The valve device is attached at the distal end of the delivery member, and is constrained within a valve cover of an outer sheath. A delivery catheter is configured to advance the valve relative to the outer sheath, and a suture catheter includes sutures/tethers which maintain proximal tension on the valve prior to deployment.

Systems and methods for delivering and deploying an artificial heart valve within the mitral annulus

A method for sealing and flushing a delivery member includes sealing one or more lumens and flushing air from the one or more lumens. An interventional device delivery system includes a handle assembly and a delivery member. The handle assembly includes a catheter holder with a passageway therethrough. A flush block is associated with the catheter holder and has a flush port and a flush chamber. The delivery member is associated with the handle assembly and includes a plurality of catheters. At least one of the catheters has a proximal end disposed within the passageway in the catheter holder and is in fluid communication with the flush chamber.

Methods, systems, and devices for sealing and flusing a delivery system

The present disclosure relates to delivery devices and interventional devices configured to enable monitoring of pressure and other hemodynamic properties before, during, and/or after a cardiac procedure. A guide catheter includes a routing lumen or a routing groove for routing a sensor wire to a desired location during a cardiac procedure. A guide catheter includes one or more pressure sensors positioned to provide desired pressure measurements when the guide catheter is deploying an interventional device. An interventional device may also include one or more associated sensors for providing hemodynamic information before, during, and/or after deployment.

Systems and methods for intra-procedural cardiac pressure monitoring

An intravascular device delivery system includes a distal end cap to connect an elongated member of the intravascular device delivery system to an intravascular device. The distal end cap includes at least one connection member radially movable relative to the distal end cap that is configured to engage with a complimentary recess in the intravascular device.

Delivery catheter distal cap

An intravascular delivery system includes a delivery sheath capable of transmitting a predetermined tension or compression force in a longitudinal direction while maintaining flexibility to navigate tortuous anatomy. A method of delivering a medical device includes inserting an intravascular device delivery system including a delivery sheath having a continuous spine into a bodily lumen. A distal longitudinal force is applied to the delivery sheath. The distal force is transmitted through the continuous spine and across one or more slit cuts of the delivery sheath. A proximal longitudinal force is applied to the delivery sheath. The proximal longitudinal force is transmitted through the continuous spine of the delivery sheath.

A medical device-includes a scaffold crimped to a catheter having an expansion balloon. The scaffold is crimped to the balloon by a process that includes inflating the delivery balloon during a diameter reduction to improve scaffold retention and maintaining an inflated balloon during the diameter reduction and prior and subsequent dwell periods.

The present disclosure describes devices, systems, and methods for intravascularly delivering an implantable device at the mitral annulus. A delivery system includes a delivery member coupled to a handle assembly and extending distally from the handle assembly. The intravascular device is attached at the distal end of the delivery member, and is housed within a distal piece of an outer sheath. A steering catheter is nested within the outer sheath to bend the delivery member into position. A delivery catheter is configured to advance the intravascular device relative to the outer sheath, and a suture catheter includes sutures/tethers which may be coupled to the intravascular device prior to deployment.

Systems and methods for delivering an intravascular device to the mitral annulus

A system for repairing a tricuspid valve and positioned at a distal end of a catheter having a proximal end and a distal end and a bore extending between the proximal end and the distal end. The system comprises an activation element extending along the bore, the activation element including a first push element and a first pull element; a second push element and a second pull element; a third push element and a third pull element; wherein the first push element, the second push element, and the third push element are independently slideable in relation to each other; a first lower jaw being pin connected to the first pull element; a second lower jaw being pin connected to the second pull element; a third lower jaw being pin connected to the third pull element.
