An intravascular lithotripsy catheter can include a sheath, first and second insulated wires, and a carrier. The first and second insulated wires can include exposed portions of an electrically conductive member and can be wound around the sheath. Exposed portions of the first and second insulated wires that form an emitter can be circumferentially offset from each other and can be longitudinally offset from each other. The carrier can encase the first and second insulated wires and the sheath and can comprise a plurality of carrier openings aligned with the exposed portions of the first and second insulated wires. The catheter can electrically connect to an energy generator that is operable to cause a spark to travel longitudinally along the catheter and circumferentially around the catheter between the exposed portions.

Intravascular lithotripsy catheter

An intravascular lithotripsy system can include a sheath configured to receive a guidewire, at least three insulated wires, and an energy generator. Each of the at least three insulated wires can comprise at least two exposed portions spaced from one another along a length of the insulated wire. The at least three insulated wires can be helically wound around the sheath and independently electrically connected with an energy generator. The exposed portions of the at least three insulated wires can define a plurality of emitters spaced from one another along a length of the sheath and which are independently operable by the energy generator. The energy generator can induce a spark via each of the plurality of emitters.

Intravascular lithotripsy system

An ablation system comprises: an ablation catheter and a console. The ablation catheter comprises: a shaft including a proximal end, a distal portion and a distal end; an ablation element configured to deliver energy to tissue; and a force maintenance assembly comprising a force maintenance element and configured to control and/or assess contact force between the ablation element and cardiac tissue. The console is configured to operably attach to the ablation catheter and comprises: an energy delivery assembly configured to provide energy to the ablation element. Methods of ablating tissue are also provided.

Ablation system with force control

A medical device is disclosed, including a handle assembly; an elongate body coupled to the handle assembly, the elongate body defining a guide wire lumen therethrough; and a substantially semi-circular electrode array coupled to the elongate body. The device may include a substantially rigid shaft extending distally from the elongate body and defining a lumen therethrough, the shaft including a substantially rigid segment, and a flexible coil coaxial with and extending distally from the shaft.

Semi-circular pulmonary vein ablation catheter

Disclosed are devices, systems, and methods for providing access to a patient. The patient access device comprises a proximal end, a distal end and a lumen therethrough. The patient access device further comprises a hollow shaft, an input port and a liquid supply port. At least a portion of the lumen passes through the shaft. The input port is coupled to the lumen, and the lumen and the input port are constructed and arranged to receive an elongate probe. The liquid supply port is in fluid communication with the lumen. The patient access is constructed and arranged to reduce gas from exiting the distal end while a portion of the elongate probe is positioned in the patient access device.

Gas-elimination patient access device

Medical devices, systems, and methods for treating patients with tissue ablation include catheter systems having bi-modal steering mechanisms, which are capable of both linear and loop ablation. In other words, the catheter system may have two different steering modes: two-dimensional and three-dimensional. In the first and second steering modes, the steering actuator may cause one or more portions of the catheter shaft to bend in different planes. A steerable ablation catheter may include treatment elements such as electrodes at its distal end and along the catheter shaft, each of which may map, pace, and ablate.

Bi-modal catheter steering mechanism

Provided is a flex-PCB catheter device that is configured to be inserted into a body lumen. The flex-PCB catheter comprises an elongate shaft, an expandable assembly, a flexible printed circuit board (flex-PCB) substrate, a plurality of electronic components and a plurality of communication paths. The elongate shaft comprises a proximal end and a distal end. The expandable assembly is configured to transition from a radially compact state to a radially expanded state. The plurality of electronic elements are coupled to the flex-PCB substrate and are configured to receive and/or transmit an electric signal. The plurality of communication paths are positioned on and/or within the flex-PCB substrate. The communication paths selectively couple the plurality of electronic elements to a plurality of electrical contacts configured to electrically connect to an electronic module configured to process the electrical signal. The flex-PCB substrate can have multiple layers, including one or more metallic layers. Acoustic matching elements and conductive traces can be includes in the flex-PCB substrate.

Devices, systems and methods are disclosed for the ablation of tissue. A steerable ablation catheter can include one or more ablation elements at its distal end and one or more ablation elements fixedly attached to its shaft. The distal end of the ablation catheter can be deflected to assume a number of different deflection geometries in at least one direction along the shaft. One feature of the ablation catheter is that its shaft can comprise materials of differing durometers or stiffnesses attached together at a joint. Methods associated with use of the ablation catheter are also covered.
