Abstract: Devices and methods are provided for performing procedure on tissue with flow monitoring using flow sensors. The devices include an elongated member, and at least one flow sensor disposed on the elongated member. The flow sensor includes at least one temperature sensor and at least one heating element having a cavity. At least a portion of the at least one temperature sensor is housed in the cavity. A temperature measurement of the temperature sensor provides an indication of the flow rate of a fluid proximate to the flow sensor.

Abstract: An expandable catheter accommodates a medical device that is being removed from a body with a larger diameter than the catheter. The same catheter may be used to reposition a device within the body to an alternative delivery site. A catheter or sheath may be used to deliver a medical device, surgical instrument, or biological sample.

Abstract: An elongate flexible wire-like medical device, such as a guidewire for use with a catheter, is formed with a shaft in which the difference between the magnitude of the tensile yield stress and compressive yield stress of the shaft is substantially reduced. The guidewire exhibits superior kink resistance without compromising other desirable characteristics and enables a guidewire to be made in a smaller diameter without loss of performance. The guidewire shaft may be formed from a precipitation hardenable alloy such as an alloy of nickel, cobalt, molybdenum and chromium (MP35N and Elgiloy), 455PH stainless steel or stainless steel alloy 1RK91. Also disclosed is a process for increasing the modulus of elasticity of an alloy of nickel, cobalt molybdenum and chromium. Further, the disclosure relates to an improved management and manufacturing process for constructing the tip of a medical guidewire.
