Implantable delivery system and method for the pharmacologic management of erectile dysfunction

An implantable delivery system for managing a patient's erectile dysfunction, comprising,

• one or more reservoir members adapted to be substantially implanted in the patient's scrotal pouch and to at least temporarily store one or more pharmacologic agents;
• one or more means for accessing and refilling one or more of said reservoir members with one or more of said pharmacologic agents;
• one or more distal end members comprising one or more perforations for dispensing at least a portion of said pharmacologic agents into one or both of the patient's cavernosal bodies;
• one or more conduits for transporting at least a portion of said pharmacologic agents from said reservoir member to said distal end member;
• and
• one or more pumps that interact with one or more of said reservoir members to release a predetermined dose of at least a portion of said pharmacologic agents from said reservoir member into one or more of said conduits.

A method for managing a patient's erectile dysfunction, comprising the steps of,

• providing an implantable delivery device, comprising,
• one or more reservoir members that is provided with a self-sealing diaphragm and adapted to be substantially implanted in the patient's scrotal pouch and to at least temporarily store one or more pharmacologic agents;
• one or more distal end members comprising one or more perforations for dispensing at least a portion of said pharmacologic agents into one or both of the patient's cavernosal bodies;
• one or more conduits for transporting at least a portion of said pharmacologic agents from said reservoir member to said distal end member;
• and
• one or more pumps that interact with one or more of said reservoir members to release an effective amount of at least a portion of said pharmacologic agents from said reservoir member into one or more of said conduits;
• surgically implanting said device so that,
• at least one of said reservoirs is implanted in the patient's subdartos scrotal pouch so that said diaphragm can be accessed with a needle;
• and
• at least one of said distal end members is implanted subtunically in at least one of the patient's corpus cavernosal bodies;
• filling at least one of said reservoirs with one or more of said pharmacologic agents by puncturing said diaphragm with a needle containing said pharmacologic agents and injecting said pharmacologic agents into said reservoirs;
• activating said pump to release said pharmacologic agents into said conduit to allow said released pharmacologic agents to be transported and dispensed into at least one of said cavernosal bodies;
• and
• refilling said reservoir with said pharmacologic agents as needed.
