摘要： Catheter devices, assemblies and related methods for percutaneous crossing of an occlusion in a blood vessel are disclosed. A catheter device can include a central catheter, two side tubes, and a distally-protruding, curved subintimal guidewire. The central catheter can define a central lumen that extends from a proximal end to a distal end of the central catheter. The lumen can be configured to receive a primary guidewire. The central catheter can also define at least one reentry aperture oriented transverse to the central lumen. The first and second side tubes can be coupled with the central catheter, extending along a longitudinal axis thereof, with the first side tube flanking an opposite side of the central catheter relative to the second side tube. The subintimal guidewire can extend from the first side tube, distally beyond the distal end of the central catheter, to the second side tube.

摘要： A catheter system includes an elongate catheter having a lumen extending at least partially therethrough, and a leading catheter end segment, a guidewire positionable within the lumen of the catheter, and fastening structure supported adjacent the leading catheter end segment. The guidewire and the catheter are adapted for relative movement. The fastening structure is dimensioned to selectively engage the guidewire to secure the guidewire with respect to the leading catheter end segment such that movement of the guidewire causes deflection of the leading end segment with respect to the longitudinal axis.

摘要： Provided is a treatment method and a medical device that can intentionally and locally administer a drug to a lesion area appearing in a narrow blood vessel such as a retinal blood vessel and a spinal blood vessel. The treatment method has an introduction step of introducing a medical elongated body having a drug holder for holding a drug into a living body, an arrangement step of arranging the drug holder at a treatment target inside the living body, and a discharge step of discharging the drug to the treatment target by releasing the drug held by the drug holder.

摘要： A guidewire system may include a guidewire having a relatively stiff proximal section and a relatively flexible distal section joined by a transition region, and a TAVI device slidably disposed on the guidewire. The guidewire may include an expandable element disposed about the transition region. The expandable element may be configured to expand from a collapsed configuration to an expanded configuration. The guidewire may include an expandable element disposed at the distal end. The distal section may be pre-configured to form more than one distal loop. A method of protecting an apex of a left ventricle during a TAVI procedure may include inserting a guidewire into the left ventricle, positioning a transition region adjacent the apex, expanding an expandable element such that the expandable element spans the apex, advancing a TAVI device distally over the guidewire to an aortic valve, and performing a TAVI procedure at the aortic valve.

摘要： Devices and methods for visually confirming the positioning of a distal end portion of an illuminating device placed within a patient include inserting a distal end portion of an illuminating device internally into a patient, emitting light from the distal end portion of the illuminating device, observing transillumination resulting from the light emitted from the distal end portion of the illuminating device that occurs on an external surface of the patient, and correlating the location of the observed transillumination on the external surface of the patient with an internal location of the patient that underlies the location of observed transillumination, to confirm positioning of the distal end portion of the illuminating device.

摘要： A supportive balloon catheter which may be used to assist a wire guide in advancing across a lesion which partially or totally occludes an intraluminal passage. The supportive balloon catheter is advanced over the wire guide, close to the location of the lesion. The supportive balloon catheter is then inflated, securing the position of the wire guide in the intraluminal passage. A braid on the catheter may provide additional structural support. The secured catheter restricts the movement of the wire guide advancing across the lesion, preventing kinking or deflection off the surface of the lesion. Once the wire guide has advanced across the lesion, the supportive balloon catheter or a different angioplasty may be used to clear the lesion from the intraluminal passage.

摘要： Guidewires are disclosed being configured to achieve variable rigidity to facilitate percutaneous exploration and the traversal of overlying elements such as catheters, for instance in performing the Seldinger technique. Embodiments of guidewires comprise sheaths and cores configured to be tightened together to achieve stiffness of the guidewire. Embodiments further include cores having an axial passage, along with one or more sections capable of independent activation to achieve variable rigidity. Embodiments also include guidewires comprising combinations of solid, wound metallic, polymeric coils, or woven meshes, with attached or detached polymer coatings. Cores may be configured to increase or decrease pressure, pass acoustic, ultrasonic or other mechanical energy, pass one or more metallic cores to interact with the distal mechanical elements, or as a channel to pass wires to activate the distal materials in the sections and distal tip.
