Abstract: An example medical device is disclosed. An example high pressure pump for use in thrombectomy system includes a cylinder having an upper region, a lower region, and a fluid pumping chamber that includes a piston rod extending within at least a portion of the fluid pumping chamber, wherein the piston rod is configured to pump fluid through a high pressure fluid supply tube. The high pressure pump also includes a high pressure connector having a first end region and a second end region, wherein the second end is coupled to the lower region of the cylinder and a high pressure seal assembly is positioned between the second end of the high pressure connector and the cylinder, and wherein the high pressure seal assembly includes a T-plate and a crush washer.

Abstract: Thrombectomy systems including a console having a radiofrequency identification (RFID) reader, a fluid inflow pump, the fluid inflow pump driven by the console, a thrombectomy catheter, the fluid inflow pump configured to provide fluid inflow through the thrombectomy catheter, and an RFID tag coupled to a body portion of the fluid inflow pump. When the fluid inflow pump is positioned within the drive unit, the RFID reader may be configured to receive one or more operating parameters from the RFID tag.

Abstract: A user interface for a thrombectomy fluid management system may include a first mode indicator configured to indicate when a first mode of fluid inflow is active, a second mode indicator configured to indicate when a second mode of fluid inflow is active, and a run time display including an alphanumeric run time value shown in a first color. The alphanumeric run time value is a sum of a first run time value of the first mode and a second run time value of the second mode. The system may include an inflow pump configured to provide fluid inflow through a thrombectomy device, a controller in communication with the inflow pump and the thrombectomy device, a user activation switch configured to activate the inflow pump, and a display including the user interface. The display may include a touchscreen user interface.

Abstract: An atherectomy system includes a drive mechanism that is adapted to rotatably actuate an atherectomy burr and a controller that is adapted to regulate operation of the drive mechanism. In some cases, the drive mechanism includes a drive cable that is coupled with the atherectomy burr and a drive motor that is adapted to rotate the drive cable. The controller is adapted to receive an indication of an increase in torque experienced at the atherectomy burr and is further adapted to, in response, regulate operation of the drive mechanism such that the increase in torque results in a noticeable reduction in speed of the drive mechanism such that a user of the atherectomy system notices the reduction in speed and is alerted to the increase in torque.

Abstract: A thrombectomy catheter deployment system which greatly simplifies setup procedures and operation of a thrombectomy catheter includes a stand alone drive unit and a disposable pump/catheter assembly which is manually placed into a carriage assembly in the drive unit. The pump/catheter assembly has a plurality of preconnected components including tubular structure and a thrombectomy catheter connected thereto and is transported into or out of the interior of the drive unit for automatic high pressure pump piston head engagement or disengagement with a reciprocating linear actuator and for automatic engagement or disengagement of an effluent waste tube with a roller pump. A barcode reader senses specific operational data pertaining to an individual pump and provides an interface for operation of the reciprocating linear actuator. A bubble trap incorporated for effective debubbling of saline solution is closely coupled to an insert molded pump having an improved valve arrangement.

Abstract: A thrombectomy catheter device having an improved hemostasis valve which is self-sealing and which functions as a one-way valve. The self-sealing hemostasis valve can be factory preset to automatically seal with or without the inclusion of a guidewire at a certain desired pressure or allowable leakage. Such sealing is automatic without the need to manually manipulate a hemostasis nut to obtain hemostasis. The thrombectomy catheter device can, without hemostasis nut adjustment, be positioned along and about a guidewire while yet maintaining suitable pressure for sustaining hemostasis at a preferred level. Certain embodiments of the thrombectomy catheter device having a self-sealing hemostasis valve include an adjustable hemostasis nut which can be manually tightened to restrict flow or guidewire movement or loosened to reduce friction on the guidewire and allow fluid to flow out if desired.
