  • Publication number: 20210228224
    Abstract: Thrombectomy apparatuses including multiple regions arranged to ensnare and stabilize a thrombus for removal from a blood vessel. Different regions of the apparatus can expand with different radial forces to improve engagement and retention of the thrombus. Different regions of the apparatus can have different diameters for encompassing the clot and for conforming to different portions of a blood vessel. Different regions of the apparatus can have a higher mesh density for capturing or retaining break away material of the clot. A junction region between the different regions of the apparatus can be arranged to enhance expansion and contraction of the apparatus.

  • Publication number: 20210161397
    Abstract: Methods of monitoring arterial blood using an arterial line tube positions adjacent to a groin sheath, as part of a surgical intervention. Described herein are methods and apparatuses (e.g., systems) for introduction of an arterial line tube for contemporaneous and sensitive blood pressure monitoring along with other instrumentation in the course of a therapeutic intervention through a femoral artery, affording improved monitoring results.

  • Publication number: 20100137899
    Abstract: An embolectomy device includes a proximal elongated shaft positionable and movable within a catheter, the proximal elongated shaft having a distal end. A distal elongated shaft positionable and movable with a catheter, the distal elongated shaft having a proximal end. An expander portion comprising a body having proximal and distal ends. The proximal end of the body extending from the distal end of the proximal elongated shaft and the proximal end of the distal elongated shaft extending from the distal end of the body of the expander portion. The body being biased to expand laterally outward from an axis of the embolectomy device. The body is shaped as an spheroid when expanded laterally outward.

  • Publication number: 20100087850
    Abstract: An embolectomy device includes an elongated shaft positionable in and movable within a catheter. The elongated shaft having a distal end portion. An expander portion having proximal and distal ends. The expander portion having a first plurality of legs connecting the proximal end of the expander portion to the distal end portion of the elongated shaft and a second plurality of legs connecting the distal end of the expander portion to the proximal end of the intermediate elongated shaft. The expander portion being biased to expand laterally outward from the long axis of the embolectomy device when the expander portion has been moved out of the catheter to engage a clot. A retrieval portion can be provided proximally of the expander portion. A retrieval net can be fixed to the retrieval portion. The expander portion can be at least partially covered by a net. A method for removing clots and other occlusions for body canals is also provided.

  • Publication number: 20100036329
    Abstract: A hemostasis valve to maintain hemostasis during the insertion, removal or reposition of a medical instrument in the vascular system of a patient. The hemostasis valve includes a valve body having lumen extending therethrough, a first valve positioned across the lumen, and having a passage with a diameter that is continuously variable, a second valve positioned across the lumen, and having a passage with a diameter that is continuously variable. The first and second valves being spaced apart longitudinally along the lumen. A connector rotatably attached to the valve body for connecting the hemostasis valve to another instrument. The first and second valves are selectively operable to create an opening through the passage respectively of a diameter to permit admittance of at least one intravascular instrument through at least one of the first and second valves while maintaining hemostasis. The second valve is rotatably attached to the valve body without effecting the diameter of the passage therethrough.

  • Publication number: 20090292307
    Abstract: An embolectomy device includes a catheter and an elongated shaft positioned in and moveable within the catheter. The shaft has proximal and distal end portions, and a retrieval portion between the proximal and distal end portions. The retrieval portion has a plurality of legs having proximal and distal end portions. Portions of the legs are movable laterally outward from a long axis of the elongated shaft when the retrieval portion is at least partially moved out of the catheter. A retrieval net can be fixed to portions of the legs for engaging a clot or other occlusion within a body canal. An expander can be provided for moving portions of an occlusion toward canal walls to open a lumen. A method for removing clots and other occlusions from body canals is also disclosed.

  • Publication number: 20050267510
    Abstract: A method and device for intravascular treatment of various vascular and intravascular issues, such as aneurysms, is disclosed. The device generally includes a multiple member, bead strand or device that includes a plurality of members interconnected with one another in a substantially flexible manner. The device may be positioned through a catheter or micro-catheter substantially intravascularly to occlude or embolize an aneurysm to substantially eliminate the possibility of perforation or rupture of the aneurysm.
