<p>CATHETER WITH ARTICULABLE SEPTUM EXTENSION A catheter (100) includes an elongated tubular body (102) including a first wall (104) and second wall (106) defining first (104a) and second lumens (104b), respectively. Each wall (104, 106) extends to a distal end (108) and defines a distal opening (118). The first and second walls (104, 106) may each include one or more side openings (1 Oa, I IOb) disposed proximal of the distal end (108). The first and second lumens (104a, 104b) are separated by a septum (112). The septum (112) includes a septum extension (114) extending distally from the septum (112). The septum extension (114) is adapted to articulate relative to the septum (112) in response to fluid flow into and out of the distal openings (118) of the first and second lumens (104a, 104b). The septum extension (114) is dimensioned to partially obstruct fluid flow into the catheter (100) through one of the distal openings (118) upon the articulation of the septum extension (114). 102 - 100 1 04a -- ' -L 104 x 114a 114b -107 - 106a 108 11 4a 1l04 110a 102 114 F 104a 114b F106ia 112 108 16 F4 110Ob 107</p> |
