Abstract: A pressure activated valve for controlling the flow of fluid through a medical device, the pressure activated valve comprises a housing including a lumen extending therethrough and a flow control membrane extending across the lumen of the housing to control the flow of fluid through the lumen by opening when a pressure threshold has been reached.

Abstract: A pressure actuated valve for controlling the flow of fluid through a medical device, the valve comprises a housing including a lumen extending therethrough and a flow control membrane extending across the lumen to control the flow of fluid through the lumen. The membrane includes a plurality of slits extending therethrough so that, when the membrane is acted upon by a pressure of at least a threshold magnitude, the slits open to permit flow through the lumen and, when not acted upon by a pressure of at least the predetermined magnitude, the slits are maintained dosed by a biasing force applied thereto by the membrane to prevent flow through the lumen. Each of the slits extends between end portions thereof along a curve wherein a distance between a first end portion of a first one of the slits and a first end portion of a second one of the slits is a minimum distance between the first and second slits.

Abstract: A method for treating a mammalian body having tissue comprising creating a cavity in the tissue formed by an internal surface of the tissue. The internal surface is ablated. An implant-forming material is introduced into the cavity to create an implant in the tissue. The ablation of the internal surface inhibits migration of the implant. An apparatus and kit for use with the method are provided.
