Medical probes for the treatment of blood vessels

摘要

Devices and methods for thermally-mediated treatment of blood vessels to elicit an immune response to cause rapid endothelial growth over at least portions of an implant or stent to prevent adverse events such as restenosis. Devices and methods for thermally-mediated treatment to inhibit contraction of vessels to elicit an immune response to cause rapid endothelial growth over at least portions of a stent to prevent adverse events such as restenosis.

主权项

1. A method of treating a muscle in a blood, vessel to reduce vasospasm in the blood vessel, the method comprising:
locating a target site within the blood vessel; and applying an amount of thermal energy at the target site where the amount of thermal energy is sufficient to reduce an ability of a muscle in a blood vessel tissue to contract, where applying the thermal energy comprises applying a flow media to the target site where the flow media comprises a heat of vaporization, where the flow media condenses at the target site to release the heat of vaporization to the blood vessel tissue causing an increase in temperature of the blood vessel tissue to reduce an ability of the muscle in the blood vessel tissue to contract.
