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

Fixation system for fixation of leaflets of a heart valve including an implantable fixation device having a first arm and a second arm, a first proximal element moveable relative to the first arm between a first position and a second position, and a second proximal element moveable relative to the second arm between a first position and a second position. The fixation system includes a delivery device having a catheter, a first proximal element line and a second proximal element line, and a handle having a first and second proximal element line handles coupled to the first proximal element line and the second proximal element line, respectively. The handle can include an interlock moveable between an unlocked position and a locked position.

Independent proximal element actuation methods

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.

Delivery system for heart valve replacement

The invention provides devices, systems and methods for tissue approximation and repair at treatment sites. The devices, systems and methods of the invention will find use in a variety of therapeutic procedures, including endovascular, minimally-invasive, and open surgical procedures, and can be used in various anatomical regions, including the abdomen, thorax, cardiovascular system, heart, intestinal tract, stomach, urinary tract, bladder, lung, and other organs, vessels, and tissues. The invention is particularly useful in those procedures requiring minimally-invasive or endovascular access to remote tissue locations, where the instruments utilized must negotiate long, narrow, and tortuous pathways to the treatment site. In addition, many of the devices and systems of the invention are adapted to be reversible and removable from the patient at any point without interference with or trauma to internal tissues.

System for fixation of leaflets of a heart valve

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

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.

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

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.

Intravascular device delivery sheath

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 method of delivering a rigid intravascular device to a target location in a patient's heart includes positioning a distal tip of an elongated member of the intravascular device delivery system in a right atrium of a heart and moving the distal tip of the elongated member into a left atrium of the heart. The method includes advancing an inner steerable catheter of the elongated member longitudinally distally relative to an outer sleeve of the elongated member a first longitudinal distance; deflecting at least a portion of the inner steerable catheter a first deflection amount; then advancing an inner steerable catheter of the elongated member longitudinally distally relative to an outer sleeve of the elongated member a second longitudinal distance; and then deflecting at least a portion of the inner steerable catheter a second deflection amount.

Methods of steering and delivery of intravascular devices

An intravascular device delivery system includes an elongated member with a proximal end, a distal end, and a longitudinal axis therebetween. The elongated member includes a multilumen catheter having a catheter wall with a plurality of lumen in the catheter wall. The plurality of lumen extends from a proximal end of the elongated member to a distal end of the elongated member. A lumen ratio of the cross-sectional area of the plurality of lumen and the cross sectional area of the catheter wall is greater than 30%.
