Abstract: A catheter torquing device is provided that enables a physician to rotate (e.g., torque) a catheter using a single hand. The provided catheter torquing device includes a catheter holder that can be slid onto a catheter. The catheter holder is adjustable between an engaged state, in which the catheter holder tightly grips the catheter, and a disengaged state, in which the catheter holder releases its grip on the catheter. When the catheter holder is in the engaged state, rotation of at least a portion of the catheter holder also rotates the catheter, whereas when the catheter holder is in the disengaged state, the catheter holder and the catheter can be translated relative to one another. The catheter torquing device further includes a base member that may be positioned directly onto a middle portion of a catheter and coupled to the catheter holder.

Abstract: A provided clot extraction system can be used for the removal of clot that may have a wall adherent component. The clot extraction system includes a cover sleeve and a telescoping 5-shaft assembly. A coring element having a blade used for physically breaking down clot is coupled to the shaft assembly. A mesh support element is coupled to the shaft assembly. An open end of a mesh is coupled to the mesh support element and a distal end of the mesh is coupled to the shaft assembly. The mesh is used to collect clot within the vessel, such as the clot that the blade of the coring element separates from the vessel wall. The shape of the coring element or the mesh support element may be altered via the shaft assembly.

Abstract: Systems and apparatuses are provided for clot extraction. In a first aspect, a system includes a first shaft, a second shaft, a third shaft, a coring element including a blade, and a mesh. The coring element has a first end and a second end. The first end of the coring element is coupled to the first shaft and the second end of the coring element is coupled to the second shaft. The mesh includes an open end and a second end. The open end of the mesh is coupled to a proximal portion of the coring element and the second end of the mesh is coupled to the third shaft through a tip structure. Other aspects and features are also claimed and described.

Abstract: Systems for use in blood clot removal can comprise a receiver-supporting element, a self- expanding receiver that includes a frame and a polymer, a first tube connected to the receiver, and a second tube positioned around at least a portion of the receiver. The receiver-supporting element can have a distal end, a proximal end, and a lumen extending proximally from the distal end. At least a portion of the self-expanding receiver can be positioned around at least a portion of a first segment of the receiver-supporting element and the first tube can be positioned around at least a portion of a second segment of the receiver-supporting element. The second tube can include separable portions.

Abstract: This invention relates to a method of uniaxially expanding a fluoropolymer product including the steps of expanding a green fluoropolymer product in a first direction to create a first-expanded fluoropolymer product, and expanding the first-expanded fluoropolymer product in the same first direction. As a result with the subject invention, it has been found that ultra-high expansion and a variety of different porous/fibril structures can be achieved by using subsequent expansion steps in the same direction. Various considerations exist with such methodology, including the selection of rates of expansion of both steps, the amount of expansion of both steps, pre-heating and cutting the product between expansion steps. Although the present invention can be used with various fluoropolymer products, it is particularly well-suited for use with PTFE.
