  • Patent number: 11642508
    Abstract: A method for thrombus detection comprising employing an elongate tube having at least one opening at a distal end of the elongate tube. A coupling is attached or formed at the proximal end of the elongate tube. The detection of the presence of a thrombus is performed by using a syringe to withdraw blood through the at least one thrombus detection opening at the distal end of the elongate tube. If little or no blood is withdrawn, or if the withdrawal of blood is more difficult than expected, the presence of a thrombus obstructing the openings is indicated.

  • Patent number: 9655753
    Abstract: A stent delivery system may be used to position a stent in a body lumen. An endoscope may be positionable in the stent delivery system facilitating direct visual observation during placement of the stent. The stent delivery system may include a first conduit, wherein the endoscope is positionable. A second conduit, wherein the first conduit is positionable, may function to releasably position the stent in the body lumen during use. The stent delivery system may include a lock that functions to inhibit movement of the first conduit relative to the second conduit during use. Retraction of the distal end of the second conduit, relative to the first conduit and the stent, may deploy the stent in a body lumen. Indicia, visibly positioned on the proximal end of the stent delivery system, may function to facilitate determination of an extent of deployment of the stent during use.
