Abstract:
1. A hemostasis hub for use with a catheter including a lumen and a proximal end, the hemostasis hub comprising: a housing including a proximal portion and a distal portion configured to be coupled to the proximal end of the catheter, the housing configured to be splittable or separable along at least one housing break line into first and second housing elements each having a distal end, the at least one housing break line extending generally longitudinally through the proximal and distal portions of the housing, the distal end of the second housing element extending distally with respect to the distal end of the first housing element and operable to support the proximal end of the catheter; a hemostasis seal in the proximal portion of the housing; and an actuator including a body portion partially slidably disposed within the proximal portion of the housing, a dilator member extending distally from the body portion, and a lumen extending through the body portion and the dilator member, the actuator being separable along an actuator break line generally aligned with the at least one housing break line; a spring retainer element disposed within the proximal portion of the housing, the spring retainer element including a tubular spring retainer member; and a spring at least partially retained within the spring retainer member, wherein the actuator is configured to assume a closed position in which the actuator lumen is fluidly isolated from the catheter lumen by the hemostasis seal, and an open position in which the dilator member extends through the hemostasis seal and the actuator lumen is in fluid communication with the catheter lumen, and wherein the hub is configured such that the spring and the spring retainer element are retained within one of the first and second housing elements upon separation of the housing and the actuator.
