  • Publication number: 20180334662
    Abstract: The present invention relates to mutated factor (FX) polypeptides and uses thereof for the treatment of haemophilia. In particular, the present invention relates to a mutated factor X (FX) polypeptide which comprises a heavy chain wherein at least one amino acid residue at position 401 or 408 is mutated.

  • Publication number: 20180038201
    Abstract: A well tool apparatus comprises a control arrangement configured to control response of the downhole tool by varying downhole drilling fluid conditions. The control arrangement includes a valve piston longitudinally slidable in a generally tubular controller housing that is in operation substantially co-axial with the wellbore, to open or close a valve port to a fluid flow connection between the drill strings interior and the tool. A latch mechanism is configured to latch the valve piston in an activated mode and/or a deactivated mode. Unlatching of the valve piston can be effected by displacement thereof in a particular axial direction to a mode change position. A stay member is automatically displaceable in the particular actual direction under hydraulic actuation responsive to above-threshold drilling fluid conditions, to obstruct movement of the valve piston under hydraulic actuation to the mode change position.

  • Publication number: 20170369861
    Abstract: The present invention relates to mutated factor (FX) polypeptides and uses thereof for the treatment of haemophilia. In particular, the present invention relates to a mutated factor X (FX) polypeptide wherein the heavy chain comprises at least one mutation selected from the group consisting of: —the mutation which consists of the substitution of the glutamic acid residue (E) at position 255 of Seq. ID No. 1 by a glutamine residue (Q), an asparagine residue (N), a serine residue (S), an alanine residue (A), or a tyrosine residue (Y); —the mutation which consists of the substitution of the glutamic acid residue (E) at position 256 of Seq. ID No. 1 by a glutamine residue (Q); and —the mutation which consists of the substitution of the glutamic acid residue (E) at position 258 of Seq. ID No.

  • Publication number: 20170130544
    Abstract: A flow-diverter assembly includes a housing having a discharge port, a valve piston located in the housing, and a barrel cam coupled to the valve piston. The valve piston includes a valve body in fluid communication with an internal flow passage of the housing, and is movable axially along a longitudinal axis of the housing between an open position, where a vent of the valve body is fluidly coupled to the discharge port, and a closed position, where the vent of the valve body is substantially sealed from the discharge port.

  • Publication number: 20170037148
    Abstract: The invention relates to an isolated monoclonal antibody that specifically binds to the D4 domain of VWF, competes for binding to VWF D4 domain with ADAMTS13 and partially inhibits ADAMTS 13 -mediated degradation of VWF. More particularly, the invention relates to an isolated monoclonal antibody comprising a heavy chain wherein the variable domain comprises at least one CDR having a sequence selected from the group consisting of SEQ ID NO: 3 for H-CDR1, SEQ ID NO: 4 for H-CDR2 and SEQ ID NO: 5 for H-CDR3 and a light chain wherein the variable domain comprises at least one CDR having a sequence selected from the group consisting of SEQ ID NO: 7 for L-CDR1, SEQ ID NO: 8 for L-CDR2 and SEQ ID NO: 9 for L-CDR3. Antibodies of the invention are presented to be useful in for the prevention or the treatment of bleeding episodes, such as bleeding episodes occurring in patients with aortic stenosis or patients with ventricular assist devices (VAD).

  • Publication number: 20170022769
    Abstract: A flexible reamer housing includes a tubular central portion including a tool bay with an aperture to allow a reamer cutter arm within the tool bay to move radially outward through the aperture, and tubular first and second auxiliary portions arranged toward opposite ends of the central portion. The first and second auxiliary portions each include a first stiffness that is less than a second stiffness of the central portion.
