  • Patent number: 12415054
    Abstract: A catheter assembly includes a catheter body extending from a catheter proximal portion to a catheter distal portion. The catheter body includes an inner liner and an outer sleeve. A braid assembly is within the catheter body and between the inner liner and the outer sleeve. The braid assembly includes a first filar array including one or more first filars helically extending around the catheter body in a first direction. The braid assembly further includes a second filar array including one or more second filars helically extending around the catheter body in a second direction opposed to the first direction.

  • Patent number: 12397129
    Abstract: Embodiments include an interventional guide catheter, comprising: a main tubular shaft with a distal tip and proximal end; the main tubular shaft comprising: a main inner structural layer comprising a metallic helically wound multi-filar wire extending from a proximal tube termination to a distal end, a braided wire layer covering the main inner structural layer that extends from the proximal tube termination to the distal end, an outer layer of polymer jacketing fixedly attached to the main inner structural layer and braid layer, an inner layer of polymer jacketing and fixedly attached to the main inner structural layer, a distal tip made of layers of polymer, a distal end curve shape for anatomical conformance that is heat processed in the main metal portion of the structure; and a lamination of the inner layer, main inner structural layer, braided wire layer and outer layer. Other embodiments are also included herein.

  • Patent number: 11712550
    Abstract: The present technology relates to a hemostasis sealing device having a device enclosure with a first seal portion for a medical device and a second seal portion for guide wire sealing. The device enclosure can be generally configured for compressive communication with a housing. The second seal portion can define a split that is in compressive communication with structural elements of the hemostasis sealing device, which can simultaneously provide sealing functionality and allow passage of relatively large-bore devices.

  • Patent number: 11179544
    Abstract: Embodiments of the invention include a single lumen catheter for delivering high pressure contrast injection for TAVR procedures. The catheter comprises a main lumen for delivering contrast media extending from the proximal end to the distal pigtail end, a distal end hole for delivering contrast media, one or more side holes proximate of the end hole along the catheter shaft on the distal angled portion, a distal angled section that is angled from the main catheter lumen axis, a distal pigtail configuration that is angled from the axis of the distal section, and a distal pigtail loop. Other embodiments are also included herein.
