A suture retention device includes a housing having one or more suture slots. The device also includes a plunger with suture slots. The plunger is slidably disposed in a channel in the housing and when the housing suture slots are aligned with the plunger suture slots, a suture filament may be disposed in the slots. When the plunger is actuated so that the housing suture slots are misaligned with the plunger suture slots, the suture filament is captured between the plunger and the housing preventing movement of the suture filament.

Suture retention device

A steerable sheath includes an elongate shaft, a handle, an actuator element on the handle, and a plurality of control wires operably coupled to the elongate shaft and the actuator element. Actuation of the actuator element adjusts a shape of a proximal curve and a distal curve on the elongate shaft.

The disclosure pertains to an intravascular catheter for nerve modulation, comprising an elongate member having a proximal end and a distal end, a balloon having a lumen and a balloon wall, the balloon wall comprising RF permeable sections and non-electrically conductive sections, an electrode disposed within the balloon and extending distally to the furthest distal RF permeable section. The RF permeable sections may comprise a plurality of RF permeable windows, each window having a greater circumferential dimension than an axial dimension. The intravascular system is suited for modulation of renal nerves.

Device and methods for nerve modulation using a novel ablation catheter with polymeric ablative elements

Devices, systems, and methods for performing a mapping procedure on body tissue are disclosed. An example mapping device for mapping a tissue surface includes an elongate shaft and an electrode assembly. The electrode assembly includes a plurality of splines and a plurality of electrodes disposed on at least some of the splines. The electrode assembly is capable of moving between a collapsed configuration and an expanded configuration. In the expanded configuration, the electrode assembly may have a generally planar structure.

High resolution cardiac mapping electrode array catheter

Devices, systems, and methods for performing ablation therapy on body tissue are disclosed. An example ablation device for treating body tissue includes an ionically conductive balloon and a radio-frequency electrode that delivers RF energy into a distal section of the balloon. The balloon can have a composite structure with a non-conductive section and a conductive section. A method for fabricating a semi-permeable ablation balloon using ionizing radiation and an etching process is also disclosed.

Devices, systems, and methods for performing ablation therapy on body tissue are disclosed. An example ablation device for treating body tissue includes an ionically conductive balloon and a radio-frequency electrode that delivers RF energy into a distal section of the balloon. The balloon can have a composite structure with a non-conductive section and a conductive section. The ablation device can have a steering mechanism configured to deflect the balloon.

Steerable ablation device with linear ionically conductive balloon

Devices, systems, and methods for performing ablation therapy on body tissue are disclosed. An example ablation device for treating body tissue includes an ionically conductive balloon and a radio-frequency electrode that delivers RF energy into a distal section of the balloon. The balloon is configured to transmit the RF energy in a direction distally towards a leading end of the ablation device. Multiple ablation electrodes on the device can be used for providing lesions of different size or shape.

Ablation device with multiple ablation modes

The present invention relates to a device for the prevention of air embolisms during a catheterization procedure. The device includes a bulb element configured to secure to a sheath assembly. The bulb element includes a flexible wall, including a proximal section and a distal section, and an interior chamber in fluid communication with a pressurized fluid source. The proximal section of the bulb element includes a proximal hub, and the distal section of the bulb element includes a distal hub. The bulb element is collapsible, under the action of an external force, from a first, relaxed state in which the interior chamber has a first volume, to a second, collapsed state in which the interior chamber has a second volume less than the first volume, and wherein the bulb element is configured to assume its first, relaxed state in the absence of the external force.

Catheter system including an embolism protection device

Methods and devices for biasing a balloon catheter are disclosed. In one example, a medical device may include a catheter shaft and a balloon assembly coupled to a distal region of the catheter shaft. The balloon assembly can define a chamber configured to be inflated and deflated using a fluid supplied from the catheter shaft. A biasing member may be positioned in the chamber of the balloon assembly and may be configured to bias the balloon assembly to a longitudinally extended state without obstructing an exhaust lumen of the catheter shaft. In some cases, the biasing member may be a spring. In other cases, the biasing member may be a coiled portion of a fluid supply line.

Loop structures for supporting diagnostic and/or therapeutic elements in contact with tissue

Methods and devices for bonding a balloon assembly, such as a balloon assembly including an inner balloon and an outer balloon, to a catheter shaft are disclosed. In some cases, a proximal waist of the inner balloon may be bonded to an interior surface of an outer tubular member of the catheter shaft and a proximal waist of the outer balloon may be bonded to an exterior surface of the outer tubular member. In other cases, the proximal waist of the inner balloon may be bonded to a reduced diameter portion of the outer tubular member of the catheter shaft and the proximal waist of the outer balloon may be bonded to the outer tubular member, such as a non-reduced outer diameter portion of the outer tubular member.
