A thrombectomy system may include an elongate shaft that defines a high pressure lumen and a low pressure lumen. The high pressure lumen may terminate near an end of the low pressure lumen. An expandable capture basket may be disposed near the end of the low pressure lumen. A thrombectomy apparatus may include an elongate shaft, an evacuation lumen extending within the elongate shaft and a high pressure lumen extending within the elongate shaft. A capture apparatus may be disposed within a wire lumen that extends within the elongate shaft such that the capture apparatus extends distally from the wire lumen.

Thrombectomy apparatus and method

A replacement heart valve assembly has a stent frame and a replacement valve. The replacement valve has a plurality of leaflets and a valve frame. The leaflets are attached to the valve frame. Further, the assembly has a plurality of suspension struts attached to the stent frame and the valve frame. The valve frame is suspended within the stent frame via the suspension struts. In some embodiments, the assembly further has a sealing member attached to the stent frame to prevent leakage around the replacement heart valve assembly.

Replacement heart valve

A catheter is configured to access a renal artery. A lumen of the catheter's shaft is dimensioned to receive a flexible actuation member which extends between the shaft's proximal and distal ends. The actuation member is moveable within the lumen and subject to elastic deformation, friction, and/or whip along its length. A flexible support member is coupled to a distal end of the actuation member and extendible beyond a distal tip of the shaft. An RF ablation electrode at a distal end of the support member is configured to ablated perivascular renal nerve tissue. A position converter at the distal end of the shaft is configured to convert movement of the actuation member into one or both of controlled rotational and axial movement of the support member and electrode to one of a multiplicity of stable circumferential positions substantially free of elastic deformation, friction, and/or whip impacting actuation member movement.

Precision electrode movement control for renal nerve ablation

Systems for nerve and tissue modulation are disclosed. An example system may include an intravascular nerve modulation system including an elongated shaft having a proximal end region and a distal end region. The system may further include a bar element extending distally from the distal end region of the elongated shaft and one or more ablation transducers affixed to the bar element.

Self-cooling ultrasound ablation catheter

Systems for nerve and tissue modulation are disclosed. An example system may include a first elongate element having a distal end and a proximal end and having at least one nerve modulation element disposed adjacent the distal end. The nerve modulation element may be positioned or moveable to target a particular target region. The nerve modulation element may be an ultrasound transducer. The nerve modulation element may be configured to be operated at a low intensity to provide a thermal nerve block or a high intensity to effect tissue modulation.

System for nerve modulation and innocuous thermal gradient nerve block

Systems and methods for monitoring and performing tissue modulation are disclosed. An example system may include an elongate shaft having a distal end region and a proximal end and having at least one modulation element and one sensing electrode disposed adjacent to the distal end region. The sensing electrode may be used to determine and monitor changes in tissue adjacent to the modulation element.

Device and methods for renal nerve modulation monitoring

Disclosed herein, among other things, are methods and apparatus related to radio frequency (RF) ablation catheters. The present subject matter provides an ablation catheter system including an ablation catheter, multiple RF electrodes positioned along a distal end of a catheter, an electrical stimulation generator, and a control circuit electrically connected to the stimulation generator. According to various embodiments, the RF electrodes are each connected to the stimulation generator using a switch, and the control circuit is configured to distribute RF power from the stimulation generator to the RF electrodes using the switches to provide ablation therapy.

Multiple electrode RF ablation catheter and method

A cardiac valve with a support frame having a first end member and a second end member opposing the first end member in a substantially fixed distance relationship, and a cover extending over the support frame to allow for unidirectional flow of a liquid through the valve.

Cardiac valve, system and method

A metallic tube arrangement includes an electrode region configured to expand radially and contract radially in response to increasing and decreasing a temperature at the electrode region, respectively. The electrode region is configured for intravascular deployment and delivery of high frequency energy to target tissue of a target vessel of the body. The electrode region is configured to expand radially to a diameter sufficient to contact an inner wall of the target vessel in response to a decrease in electrode region temperature and to contract radially to a diameter smaller than a diameter of the target vessel in response to an increase in electrode region temperature.
