Abstract
A septum for sealably covering a fluid cavity defined in an implantable device, which may be an access port, and methods for assembling the implantable device. The septum may include a resilient septum body, an annular flange extending radially outward from the septum body, and a reinforcement component disposed in the annular flange for reinforcing engagement with a corresponding annular groove defined in a body of the implantable device. The reinforcement component may inhibit unintended detachment of the septum from the implantable device.
Claims4
A method for assembling an implantable access port, comprising:
- providing a housing defining an opening, a fluid cavity under the opening, and a groove between the opening and the fluid cavity;
- and
- inserting a needle-penetrable septum through the opening, the needle-penetrable septum including a flange and a reinforcement structure disposed at least partially within the flange, the inserting comprising:
- deforming the needle-penetrable septum from a first shape configuration to a second shape configuration;
- inserting at least a portion of the flange into the groove;
- and
- transitioning the needle-penetrable septum from the second shape configuration to the first shape configuration such that a remainder of the flange is seated within the groove and the needle-penetrable septum covers the fluid cavity.
