20080312671 | Infusion flow guidewire system - An infusion flow guidewire system including a delivery sheath and an infusion flow guidewire. The minimal cross section flexible infusion flow guidewire includes a nitinol hypotube, a flexible tip and distally located rearwardly directed orifices 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 torquing and for longitudinal actuation along and within the vasculature. | 12-18-2008 |
20100312223 | RAPID EXCHANGE FLUID JET CATHETER AND METHOD - 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 | 12-09-2010 |
20130131691 | RAPID EXCHANGE FLUID JET CATHETER AND METHOD - 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 | 05-23-2013 |
20140094835 | INFUSION FLOW GUIDEWIRE 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. | 04-03-2014 |

20110208205 | Thrombectomy Catheter Deployment System - 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. | 08-25-2011 |
20130310845 | THROMBECTOMY CATHETER DEPLOYMENT 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.

20130172778 | METHODS AND SYSTEMS FOR MEDICAL HOME TESTING - Methods and systems for medical home testing are described. In one embodiment, the device includes a case member, a plunger member, an accumulator member and a handle member. The case member has a first distal end portion and a first proximal end portion. The first distal end portion has a distal opening and the first proximal end portion has an aperture. The plunger member is sized and configured for sliding through the aperture. The plunger member has a second distal end portion configured to slide within the case member. The accumulator member is disposed in the case member adjacent the plunger member. The accumulator member is compressed by the case member and configured for sliding through the distal opening as the plunger slides through the aperture. The handle member is attached to the accumulator member and extends through the plunger member. Other methods and systems are also described. | 07-04-2013 |
