Abstract
The present technology relates to systems and methods for removing a thrombus from a blood vessel of a patient. In some embodiments, the present technology is directed to systems including an elongated catheter having a distal portion configured to be positioned within the blood vessel of the patient, a proximal portion configured to be external to the patient, and a lumen extending therebetween. The system can also include a fluid delivery mechanism coupled with a fluid lumen and configured to apply fluid to at least partially fragment the thrombus, and an aspiration mechanism fluidly coupled to an aspiration lumen and configured to aspirate the fragmented thrombus.
Claims22
A medical system, comprising:
- a compliant shaft;
- a guidewire system coupled to the compliant shaft, the guidewire system including:
- a lumen configured to receive a guidewire;
- a plurality of inflatable members disposed along the lumen, the plurality of inflatable members being configured to be inflated sequentially to engage with the guidewire and decrease a length of the lumen to cause the guidewire system and compliant shaft to advance along the guidewire.
A thrombus removal device, comprising:
- an elongate catheter shaft configured to be positioned withing a blood vessel of a patient;
- an expandable distal portion coupled to the elongate catheter shaft;
- a plurality of inflatable members disposed on the elongate catheter shaft, the plurality of inflatable members being configured to be inflated sequentially to decrease a length of the elongate catheter and cause the thrombus removal device to advance within the blood vessel.
