  • Patent number: 9539092
    Abstract: A heart valve delivery system is provided wherein a prosthetic valve is carried on a valve catheter inside a delivery sleeve. A step balloon protrudes from the delivery sleeve and provides a tapered surface for facilitating advancement through a body vessel. The step balloon also aids in crossing the leaflets of a native valve. After the prosthetic valve is positioned within the native valve, the delivery sleeve is retracted to expose the prosthetic valve. If necessary, the step balloon may be expanded to securely seat the prosthetic valve at the site of the native valve. The prosthetic valve is preferably coupled to the valve catheter by a plurality of flexible extension arms which allow the prosthetic valve to be collapsed after initial deployment such that the prosthetic valve may be repositioned if necessary.

  • Publication number: 20160031945
    Abstract: N-type voltage-gated calcium channels (CaV2.2) are critical mediators of neurotransmitter release and are thought to be involved with transmission of nociception. The use of conventional CaV2.2 blockers in pain therapeutics is limited by side effects. Reported herein is a means to suppress both inflammatory and neuropathic pain without directly blocking CaV2.2, but rather by inhibiting the binding of the axonal collapsin response mediator protein 2 (CRMP-2), a protein known to enhance CaV2.2 function. A 15 amino acid peptide of CRMP-2 fused to the protein transduction domain of the HIV tat protein (TAT CBD3) reduced meningeal blood flow induced by activation of the trigeminovascular system, prevented inflammation-induced tactile hypernociception induced by intraplantar formalin and nocifensive behavior following corneal capsaicin application, and reversed neuropathic hypernociception produced by the antiretroviral drug 2?,3?-dideoxycytidine. Preventing CRMP-2-mediated enhancement of CaV2.
