摘要： A method of imaging a vessel with a catheter includes positioning an imaging tip in a reinforced terminal section of an outer sheath of the catheter, inserting the catheter into a vessel, and performing near infrared spectroscopy of the vessel by retracting the imaging tip to a retracted position proximally spaced from the reinforced terminal section of the outer sheath, transmitting near infrared light from the imaging tip to the vessel wall via the outer sheath, and collecting near infrared light from the vessel wall at the imaging tip via the outer sheath. Transmitting and collecting may be performed after retracting the cable and while the imaging tip is rotated and translated proximally from the retracted position along the outer sheath. Ultrasound energy may be transmitted to the vessel from a transducer on the imaging tip and received from the vessel at the transducer.

摘要： An endovascular apparatus can comprise an array of emitters configured to emit light at a predetermined wavelength and an array of sensors configured to detect light emitted by the emitters and reflected off a surface. The device can be configured to be inserted into a stent within a blood vessel of a patient and the device can be configured to detect the location of a branch blood vessel based on the reflected light detected by the array of sensors. Some devices detect light through a stent wall from an emitter positioned in the branch vessel. Some devices include fiber optics or phototransistors for receiving light from the emitter. Some devices include a fenestration former and a guidewire director along with the light receivers all in one endovascular device.

摘要： Guidewire-management devices and systems thereof are disclosed herein. A guidewire-management device can include a guidewire, a first sleeve, and a second sleeve. The first sleeve can be configured for distally feeding the guidewire out of the guidewire-management device. The first sleeve can also be configured for proximally feeding the guidewire into the guidewire-management device. The second sleeve can be proximal of the first sleeve in the guidewire-management device. The second sleeve can be configured for feeding the guidewire in concert with the first sleeve. At least a length of the guidewire extending between the first sleeve and the second sleeve can be disposed within a sterile barrier configured to maintain sterility of the guidewire.

摘要： A catheter includes a shaft having a first lumen inside thereof, an expansion/contraction portion that is disposed on a distal end portion of the shaft and is expandable and contractible in a radial direction, and an actuation portion that expands and contracts the expansion/contraction portion. The expansion/contraction portion has a fixed portion fixed to the shaft, a sliding portion capable of sliding in a longitudinal direction of the shaft on an outer peripheral face of the shaft, and a suspension portion extending in the longitudinal direction of the shaft that connects the fixed portion with the sliding portion. When the sliding portion is slid toward the fixed portion by the actuation portion, the suspension portion expands in a radial direction of the shaft.

摘要： An intravascular safety guidewire including an elongated main shaft, a distal terminus extending from the elongated main shaft, and an anchor rotatably connected to the distal terminus. In use, a needle is inserted into a patient's vein, then the intravascular safety guidewire is placed through the needle and into the vein, the needle is then removed over the intravascular safety guidewire, then a venous catheter is exchanged over the intravascular safety guidewire following serial dilatation using the Seldinger technique. Tubes such as dilators and catheters can then be placed over the intravascular safety guidewire and the intravascular safety guidewire ultimately removed. Currently complications can arise if a guidewire becomes retained inside a patient during an endovascular procedure, which is associated with high morbidity and mortality rates. The instant intravascular safety guidewire with its rotatable anchor reduces the likelihood of this complication.
