A thrombectomy catheter deployment for operation of a thrombectomy catheter may include 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 may have a plurality of preconnected components including a tubular structure and a thrombectomy catheter connected thereto. A barcode reader may sense specific operational data pertaining to an individual pump and may provide an interface for operation of the reciprocating linear actuator.

Thrombectomy catheter deployment system

An infusion flow guidewire and a system including an infusion flow guidewire. The minimal cross section flexible infusion flow guidewire includes a nitinol hypotube, a flexible tip having a closed distal end, a coil, a core wire and at least one distally located rearwardly directed jet orifice for infusion of fibrinolytics and for introduction of high pressure fluids for maceration and rearwardly directed flow of thrombus debris located in tortuous small sized vessels. Apparatus, some of which is removably attachable, is provided in the system for grasping members of the invention for rotational torqueing and for longitudinal actuation along and within the vasculature.

Infusion flow guidewire system

A thrombectomy catheter deployment for 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 of 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.

Catheters including guidewire tubes having a limited length and methods of using the catheters are described. The catheters may be delivered over guidewires in procedures that are commonly referred to as rapid-exchange delivery. In some embodiments, the catheters may be miniature flexible thrombectomy catheters that may be used to remove thrombus or other unwanted material from a body blood vessel or other small regions of body cavities in which the distal portion of the catheter has smaller external dimensions than the larger proximal portion.

Rapid exchange fluid jet catheter

An infusion flow guidewire system and method of use. The infusion flow guidewire system includes a delivery sheath and an infusion flow guidewire. The minimal cross section flexible infusion flow guidewire includes a flexible tip having a closed distal end, a coil, a core wire and at least one distally located jet orifice for infusion of fibrinolytics and for introduction of high pressure fluids for maceration and rearwardly directed flow of thrombus debris located in tortuous small sized vessels. Apparatus, some of which is removably attachable, is provided for grasping members of the invention for rotational torqueing and for longitudinal actuation along and within the vasculature.

Methods of conducting thrombectomy procedures and deploying a thrombectomy catheter are disclosed. A thrombectomy procedure is conducted with a thrombectomy catheter deployment system. A drive unit configured to operate an infusion pump is provided. The drive unit is operable according to one or more operating modes. A preconnected and consolidated pump and catheter assembly configured for loading in the drive unit is also provided. The assembly is separate from the drive unit prior to loading. The infusion pump and a catheter of the assembly are in communication prior to loading. The assembly provides one or more digital instructions to the drive unit. The drive unit is operable according to the one or more operating modes referenced by the one or more digital instructions. The assembly is loaded into the drive unit, and the drive unit is engaged to the infusion pump for operation of the infusion pump.

Methods of conducting thrombectomy procedures and deploying a thrombectomy catheter

Rapid exchange fluid jet catheter and method

The present invention pertains to a miniature flexible thrombectomy catheter having one or more flexible miniature noncollapsing tubular portions including pushable and torqueable structure for introduction into the smaller vessels in neurovascular regions. A jet body having an arcuate fluid jet emanator is incorporated in order to minimize size at the distal portion of a minimally sized catheter tube.

Miniature flexible thrombectomy catheter

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. A spiked bag with large tubing is incorporated for bubble-free transfer of saline.
