Abstract: At least one tab may extend through at least one opening in a retaining member configured to cover at least a portion of a head of a reservoir body and a portion of a septum supported by the head of the reservoir body. A retaining member may be configured to cover at least a portion of a first head of a reservoir body and a portion of a septum supported by the first head of the reservoir body, and the reservoir body may have a second head having at least one tab. A retaining member located in a head of a reservoir body may be for retaining a septum on the head of the reservoir body, and the head of the reservoir body may have at least one tab.

Abstract: A delivery device includes a durable housing portion and a separable disposable portion that selectively engage and disengage from each other. The disposable housing portion secures to the patient-user and may be disposed of after it has been in use for a prescribed period. Components that normally come into contact with a patient-user or with infusion medium are supported by the disposable housing portion, while the durable housing portion supports other components such as electronics and a drive device. A reservoir is supported by the disposable housing portion and has a moveable plunger that operatively couples to the drive device, when the disposable and durable housing portions are engaged.

Abstract: An infusion set for subcutaneous delivery of an infusant. The infusion set may include a base removably attachable to an infusion site and a connector temporarily lockable to the base. The connector can engage the base in a plurality of orientations. The connector locks into the base after at least partial rotation of the connector about the base. The connector may include flexible arms which unlock the connector from the base. The base includes a cannula for insertion through the infusion site. The connector includes a tubing for passing the infusant. The infusant is subcutaneously passable from the tubing through the cannula when the connector is attached to the base. The infusion set may also include a hub removably attachable to the base that includes a needle that extends through the base and the cannula and a guard removably attachable to the base opposite the hub for surrounding the needle.

Abstract: An improved pump, reservoir and reservoir piston are provided for controlled delivery of fluids. A motor is operably coupled to a drive member, such as a drive screw, which is adapted to advance a plunger slide in response to operation of the motor. The plunger slide is removably coupled to the piston. The piston comprises a first member and a second member. The first member has an external proximate side and an external distal side. The external proximate side is adapted to contact the fluid and is made of a material having a first stiffness. The second member has a first side and a second side and is at least partially disposed within the first member. The first side of the second member is adjacent to the external proximate side of the first member and is made of a material having a stiffness which is greater than the first stiffness.

Abstract: A septum used for sealing an opening formed in a neck of a container, the septum includes a top septum member that fits over the outside of the opening in the container and a bottom radial septum member structurally connected below the top septum to seal inside the neck of the container.

Abstract: The present invention provides a novel tissue cutting device for autologous tissue heart valves which accurately cuts the tissue to a predetermined configuration in a minimal amount of time. The disposable tissue cutting die of the present invention is comprised of a cover, a base member, a continuous blade enclosing a desired spatial configuration and an actuator for forcing said tissue against the entire perimeter of the blade.

Abstract: The present invention provides a prosthetic heart valve holder specifically configured to hold a prosthetic heart valve comprised of a stent. The heart valve holder assembly has three main components: a handle, a valve capture loop assembly and a valve retainer. The prosthetic heart valve is secured to the valve retainer by a loop of suture as the surgeon sutures or attaches the valve to the annulus of the heart. Thus, the valve holder assembly facilitates attachment of the prosthetic valve to the annulus so that the procedure may be performed in a time and labor efficient manner.

Abstract: An assembly tool for a bioprosthetic heart valve is disclosed. The tool assembles a valve having an inner and a spreadable outer stent, and includes a spreading ring with an elevated lip to hold the spread outer stent, an expander having fingers which contact the outer stent base to spread it apart, and a plunger to spread the fingers of the outer stent. An assembly mandrel having indexing rails allows the insertion of the inner stent into the spread outer stent while maintaining the correct rotational positioning of both stents. A shedding cap protects the tissue wrapped on the inner stent from abrasion during insertion.
