Insertable ultrasound probes, systems, and methods for thermal therapy
First Claim
1. A method for producing hemostasis, tissue closure, and/or vessel closure following a percutaneous medical procedure wherein an access device is introduced to a patient creating a passageway, said method comprising the step of:
- a) inserting a thermal delivery probe into the passageway;
b) determining a site at which thermal energy should be applied;
c) emitting sufficient thermal energy to the site in order to raise native tissue temperatures; and
d) inducing tissue and/or blood coagulation at the site.

Abstract
Disclosed herein are methods and systems for producing hemostasis, tissue closure, or vessel closure by inserting a thermal delivery probe into a passageway and emitting thermal energy from the probe to produce the hemostasis or tissue closure. These methods and systems may be used following a percutaneous medical procedure that creates a passageway in tissue of patient, such as is caused by introduction of an access device into the patient. The thermal delivery probe may have one or more ultrasound transducers positioned in an elongated shaft.

18. A therapeutic medical device adapted to be inserted into a tissue passageway following a percutaneous medical procedure, comprising:
-
a) an elongated shaft having a proximal section, a distal section, a distal tip and at least one lumen extending longitudinally from the distal tip to a proximal end located in the proximal section;
b) a means for locating and determining a site at which thermal energy should be applied to promote hemostasis; and
c) a means for emitting sufficient thermal energy to the site thereby raising native tissue temperatures thereby inducing tissue and/or blood coagulation.
