  • Patent number: 11964144
    Abstract: A method of coupling components of a catheter pump assembly includes providing an elongate polymeric tubular body having a proximal end and a distal end, and also providing a metallic tubular body having a proximal portion and a distal portion. The method further includes positioning a mechanical interface having a first interface zone and a second interface zone such that the first interface zone is disposed over a portion of the elongate polymeric tubular body adjacent to the distal end thereof. The method also includes flowing the polymer into the first interface zone, whereby the elongate polymeric tubular body becomes joined with the first interface zone of the mechanical interface, and coupling the metallic tubular body with the second interface zone of the mechanical interface.

  • Patent number: 11964119
    Abstract: A catheter pump includes a catheter body having at least one lumen therethrough, and comprising a distal end and a proximal end. An expandable impeller assembly includes an expandable impeller and an expandable cannula coupled to the distal end of the catheter body and housing the expandable impeller, the expandable cannula comprising a substantially straight segment having a distal inlet and a proximal outlet, the substantially straight segment configured to straddle an aortic valve. The catheter body comprises a proximal vessel contact zone and a distal vessel contact zone that are each proximal to the substantially straight segment, the proximal vessel contact zone and distal vessel contact zone configured to provide a force against an aortic arch to stabilize the expandable impeller assembly across the aortic valve.

  • Publication number: 20190100534
    Abstract: Cephem and penem compounds having a styrylmethylene moiety at the 3-position in the cephem or penem ring to which a positively charged leaving group is bonded and wherein the leaving group contains a vicinal diol or is bonded to a unsubstituted or substituted catechol. The leaving group can be a positively charge nitrogen leaving group. Cephems include cephalosporins, cephamycins, carbacephems, and oxacephems. Penems include penems, carbapenems and oxapenems. Preferred cephems are cephalosporins. Preferred penems are carbapenems. Compounds exhibit antibiotic activity against Gram-negative bacteria and/or Gram-positive bacteria. Compounds exhibit antibiotic activity against bacteria which exhibit multi-drug resistance. Compounds of the invention exhibit antibiotic activity against bacterial strains which produce extended spectrum beta-lactamases (ESBL), which produce AmpC beta-lactamases or which produce a carbapenemase.
