RETRACTION AND ASPIRATION DEVICE FOR TREATING EMBOLISM AND ASSOCIATED SYSTEMS AND METHODS
First Claim
1. An apparatus for use with a catheter system, wherein the catheter system enables intravascular delivery of an interventional device to a treatment site in a blood vessel, the apparatus comprising:
- a housing configured to be releasably coupled to a proximal portion of the catheter system;
an actuation mechanism coupled to the housing, wherein the actuation mechanism includes—
a lever movably coupled to the housing;
a locking portion configured to engage a portion of the catheter system;
a pressure source coupled to the housing and the actuation mechanism; and
wherein movement of the lever simultaneously—
activates the pressure source to generate pressure, andmoves the locking portion to engage and retract at least a portion of the catheter system.

Abstract
Retraction and aspiration devices, systems, and methods are disclosed herein. One aspect of the present technology, for example, is directed toward an apparatus for use with a catheter system configured to enable intravascular delivery of an interventional device to a treatment site in a blood vessel. The apparatus can include a housing configured to be releasably coupled to a proximal portion of the catheter system and an actuation mechanism coupled to the housing. The actuation mechanism can include a lever movably coupled to the housing, a locking portion configured to engage a portion of the catheter system, and a pressure source coupled to the housing and the actuation mechanism. Movement of the lever simultaneously activates the pressure source to generate pressure, and moves the locking portion to engage and retract at least a portion of the catheter system.

6. A system for extracting thrombus from a blood vessel of a human patient, the system comprising:
-
a catheter including— a first elongated shaft having proximal portion and a distal portion, wherein an inner surface of the first elongated shaft defines a lumen, a second elongated shaft positioned at least partially within the lumen of the first elongated shaft, wherein the second elongated shaft has a proximal portion and a distal portion, and a treatment device coupled to the distal portion of the second elongated shaft; a pressure source; a tubing system coupled to the lumen and the pressure source; a retraction and aspiration device including an actuation mechanism configured to be coupled to the pressure source and at least one of the first and/or second elongated shafts, wherein the actuation mechanism includes a lever; and wherein movement of the lever simultaneously generates a negative pressure in the lumen and retracts the second elongated shaft. - View Dependent Claims (7, 8, 9, 10)
