Guidewires and methods for transmitting electrical stimuli to a heart and for guiding and supporting the delivery of elongate treatment devices within the heart are disclosed. A guidewire can comprise an elongate body, including first and second elongate conductors, and at least first and second electrodes. A distal end portion of the elongate body can include a preformed bias shape, such as a pigtail-shaped region, on which the first and second electrodes can be located. The preformed bias shape can optionally be non-coplanar relative to an intermediate portion of the elongate body. The first and second elongate conductors can be formed of a single structure or two or more electrically connected structures. The conductors can extend from proximal end portions to distal end portions that electrically connect to the first and second electrodes. A corewire can extend the length of the elongate body, can at least partially form the first conductor, and can be at least partially surrounded by the second conductor.

Pacing guidewire

Devices and methods for the treatment of chronic total occlusions are provided. One disclosed embodiment comprises a method of facilitating treatment via a vascular wall defining a vascular lumen containing an occlusion therein. The method includes providing an intravascular device having a distal portion with a side port, inserting the device into the vascular lumen, positioning the distal portion in the vascular wall, directing the distal portion within the vascular wall such that the distal portion moves at least partially laterally, and directing the side port towards the vascular lumen.

Endovascular devices and methods

Closure systems, kits and methods for sealing a percutaneous puncture or other opening in a blood vessel wall, body cavity or biopsy tract are disclosed. A closure system can comprise an implant assembly, a delivery assembly, and an introducer sheath. The closure system can further comprise a valve bypass and a dilator. The implant assembly can include an inner member, a sealing membrane, and an outer member, each of which can be delivered by the delivery assembly. The inner member can be extended through the puncture or opening and positioned adjacent an inner tissue surface. The outer member can be positioned adjacent an outer tissue surface. The sealing membrane can have a distal end attached to the inner member, a proximal end including an opening configured to receive the outer member, and a mid-region therebetween. The outer member, when expanded from a delivery configuration to a sealing configuration, can urge the mid-region of the sealing membrane radially outward such that its outer surface can contact and conform to a perimeter edge of the puncture or opening.

Closure device for sealing percutaneous opening in a vessel

Percutaneous devices and methods for releasably engaging a guidewire against an inner surface of a tubular member are disclosed. A percutaneous device can include a tube member, a push member, and a fixation mechanism such as a fixation balloon. The tube member can define a lumen sized and shaped to receive one or more interventional medical devices therethrough and can have an outer diameter smaller than a lumen of a guide catheter. The push member can extend proximal of the tube member for slidably positioning a distal end portion of the tube member within and beyond a distal end of the guide catheter. The push member can include a lumen in fluid communication with an interior of the fixation balloon, for example, for delivering inflation fluid to, or removing fluid from, the balloon. The fixation balloon can be positioned can be positioned and configured to engage a guidewire against the inner surface of the guide catheter or of the tube member when inflated.

Guidewire fixation

Catheters incorporating a thin film polymeric layer or layers. The thin film may have a wall thickness of about 0.00025″+/−less than 0.0001″ to about 0.0015″+/−0.0002″, for example. The thin film may be formed by extruding a sheet and cutting the sheet into elongate ribbons, each having two opposing long edges. The ribbon may be rolled or wrapped to define a tubular shape with a gap between the long edges. Heat and pressure may be applied to close the gap, abut the edges and form a longitudinal joint. The joint may extend along a portion of the length of the tubular shaft or most of the length of the tubular shaft. The tubular-shaped thin film layer may have a uniform wall thickness around the circumference, and the uniform wall thickness may extend across the joint.

Catheters and related devices and methods of manufacture

Devices and methods for the treatment of chronic total occlusions are provided. One disclosed embodiment comprises a method of facilitating treatment via a vascular wall defining a vascular lumen containing an occlusion therein. The method includes providing a first intravascular device having a distal portion with a concave side, inserting the first device into the vascular lumen, positioning the distal portion in the vascular wall, and orienting the concave side of the distal portion toward the vascular lumen.

Endovascular devices and methods for exploiting intramural space

Devices and methods for the treatment of chronic total occlusions are provided. One disclosed embodiment comprises a method of facilitating treatment via a vascular wall defining a vascular lumen containing an occlusion therein. The method includes inserting an intramural crossing device into the vascular lumen, positioning at least the distal tip of the crossing device in the vascular wall, advancing an orienting device over the crossing device such that an orienting element of the orienting device resides in the vascular wall, inserting a reentry device, and re-entering the true vascular lumen.

Devices and methods for the treatment of chronic total occlusions are provided. One disclosed embodiment comprises a method of facilitating treatment via a vascular wall defining a vascular lumen containing an occlusion therein. The method includes providing an intravascular device having a distal portion with a lumen extending therein; inserting the device into the vascular lumen; positioning the distal portion in the vascular wall; and directing the distal portion within the vascular wall.

The present disclosure is directed to a device. The device may include a distal shaft defining a central lumen and an orienting element comprising at least one inflatable member. Wherein a first portion of the orienting element extending from the shaft in a first direction and a second portion of the orienting element extending from the shaft in a second direction. Further, wherein the second direction is substantially opposite the first direction.

Devices and methods for the treatment of chronic total occlusions are provided. One disclosed embodiment comprises a method of facilitating treatment via a vascular wall defining a vascular lumen containing an occlusion therein. The method includes providing an intravascular device having a distal portion, inserting the device into the vascular lumen, positioning the distal portion in the vascular wall to at least partially surround the occlusion, and removing at least a portion of the surrounded occlusion from the lumen.

The present disclosure is directed to a method of facilitating treatment via a vascular wall defining a vascular lumen containing an occlusion therein. The method may include providing an intravascular device having a distal portion and a longitudinal axis and inserting the intravascular device into the vascular lumen. The method may further include positioning the distal portion in the vascular wall, rotating the intravascular device about the longitudinal axis, and advancing the intravascular device within the vascular wall.

Methods and devices for crossing chronic total occlusions

Devices, systems and methods for treating diseases and disorders effecting the cardiovascular system of the human body are disclosed. An exemplary device in accordance with this disclosure comprises a shaft, tip member fixed to the shaft, and a probe extending beyond a distal surface of the tip member. In some useful embodiments, the tip member is relatively atraumatic and the probe is shaped so as to be more likely to produce trauma than the tip member.
