摘要： Tissue puncture devices, and systems and methods for accessing tissue (e.g., cardiovascular tissue) according to the present disclosure may include a tubular sheath extending along a longitudinal axis, the tubular sheath having a proximal end and a distal end, a needle disposed coaxially in the sheath, the needle having a proximal end and a distal end and being movable along the longitudinal axis of sheath, and a needle control mechanism disposed at the proximal end of the needle, the needle control mechanism being configured to lock the distal end of the needle in a first position retracted within the distal end of the sheath, and release the needle to an unlocked second position such that the distal end of the needle is extendable beyond the distal end of the sheath.

摘要： A direct visualization catheter includes a handle, a balloon, an elongate shaft, and a camera assembly. The elongate shaft has a proximal end and a distal end opposite the proximal end. The proximal end is coupled to the handle. The distal end is coupled to the balloon and defines a longitudinal axis. The camera assembly is coupled to the distal end of the elongate shaft and is disposed within the balloon. The camera assembly includes a camera and an adjustment mechanism for varying a configuration of the camera relative to the distal end of the elongate shaft between a delivery configuration and a deployed configuration. The camera faces primarily in a radial direction in the delivery configuration and the camera faces primarily in an axial direction in the deployed configuration.

摘要： A medical device may include an elongate delivery sheath and a valve replacement implant disposed within a lumen of the delivery sheath, the implant including an anchor member reversibly actuatable between a delivery configuration and a deployed configuration. The implant may include at least one locking element configured to lock the anchor member in the deployed configuration, and at least one actuator element configured to engage the at least one locking element and actuate the anchor member between the delivery configuration and the deployed configuration. The at least one actuator element may include an unlocking member configured to compress a first locking portion of the at least one locking element to unlock the anchor member from the deployed configuration.

摘要： Various aspects of the present disclosure are directed toward apparatuses, systems, and methods for crossing a tissue region. The apparatuses, systems, and methods may include a catheter and a tip section arranged therewith. The tip section may be configured to puncture the tissue region and create an opening therein, dilate the opening in the tissue region, and pass through the opening.

摘要： Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a guide extension catheter. The guide extension catheter may include an elongate tubular member having a proximal region, a distal region, and a slot formed in the tubular member between the proximal region and the distal region. The proximal region of the tubular member may be configured to shift between a first configuration and a collapsed configuration. The guide extension catheter may also include an elongate shaft for shifting the proximal region between the first configuration and the collapsed configuration.

摘要： Catheter systems and methods for determining blood flow rates based on light reflection measurements. The catheter may include a lumen extending between a proximal end of the catheter and a distal end of the catheter. The catheter may include fluid infusion openings at the distal end region of the catheter that are configured to permit the indicator fluid to exit the catheter from the lumen. The catheter system may include an optical fiber having one or more sensors thereon for sensing light reflected by blood particles in a body vessel lumen. A blood flow rate may be determined based on the sensed light reflected by blood particles in the body vessel lumen.
