BREAK-AWAY HEMOSTASIS HUB
First Claim
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 into first and second housing elements;
a hemostasis seal in the proximal portion of the housing; and
an actuator partially slidably disposed within the proximal portion of the housing, the actuator including a body portion, a dilator member extending distally from the body portion, and a lumen extending through the body portion and the dilator 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.

Abstract
A breakaway hemostasis hub for a catheter or introducer sheath includes a splittable or separable housing, a seal within the housing, an actuator partially slidably disposed within the housing, a pair of spring retainer members in the housing each adapted to receive at least one spring, and a pair of actuator retainer members adapted to retain the seal, the actuator, and the spring retainer members in the housing. The actuator is operable to assume a closed position and an open position and includes a dilator member configured to dilate the seal when the actuator is in the open position. The hub is splittable or separable into two generally symmetrical sub-assemblies to facilitate cutting the catheter for retraction from the patient'"'"'s body without displacing its payload.

18. A hemostasis hub for use in combination with a catheter having a proximal end and a lumen extending distally from the proximal end, the hemostasis hub comprising:
-
a splittable or separable housing having a proximal portion and a distal portion configured to be coupled to the proximal end of the catheter, the housing defining an interior space; a hemostasis seal within the housing; and an actuator partially slidably disposed in the interior space and including a dilator member configured to dilate the seal, and an actuator lumen extending through the dilator member. - View Dependent Claims (19, 20)

21. A catheter and hemostasis hub assembly comprising:
-
an elongate catheter including a proximal end and a lumen extending distally from the proximal end; and a hemostasis hub coupled to the proximal end of the catheter, the hub including; a housing defining an interior space in fluid communication with the catheter lumen, the housing including a proximal portion and a distal portion coupled to the proximal end of the catheter, the housing further including first and second housing elements; a resilient seal member within the housing configured to hemostatically isolate the catheter lumen from the open proximal end of the housing; and an actuator including mating first and second actuator elements partially slidably disposed within the housing configured to dilate the seal for introducing an elongate medical device or instrument into the catheter lumen; wherein the hub is further configured to be splittable into a first hub subassembly including the first housing element and the first actuator element, and a second hub subassembly including the second housing element and the second actuator element. - View Dependent Claims (22, 23, 24, 25)
