A medical system, comprising an implantable access port including an implantable access port body and at least one implantable access port needle; wherein the at least one needle is concealable inside the access port body in a concealed position and is exposable outside the access port body in an exposed position; wherein the at least one needle is arranged within the access port body to penetrate outwardly through skin of a subject from within the subject when the access port is implanted in the subject; a transfer device coupled to the at least one needle of the access port, the transfer device configured to transfer a fluid to and/or from the access port; and wherein the transfer device is configured to form a closed system with the access port, wherein the transfer device includes a fluid flow passage configured to transfer the fluid to and/or from the access port.

Embodiments of the present invention provide a vent arrangement integrated with a refill port disposed on the outer shell of an implantable drug-delivery device. The vent arrangement may utilize a tiered structure with two septums in a space-efficient configuration that facilitates both venting of pressure and refill of the drug reservoir.

A fluid delivery system for delivering fluid to an inner ear of a subject includes a septum configured to be embedded in the inner ear or on a promontory bone of the subject, a spear connector having a needle for insertion into the septum, a catheter in fluid communication with the spear connector, a fixation device configured to secure the septum to the inner ear or the promontory bone.

The device presented is designed to cause, in a mode of operation referred to as normal mode, a fluid to flow along this fluid path successively through the first cavity, the filter, the second cavity then the flow restrictor. The device is also designed to cause, in a mode of operation referred to as purge mode, a fluid to flow along this same fluid path through the filter but in the opposite direction to the normal flow of the fluid (in the normal mode of operation). Thanks to the purge mode, the fluid will detach impurities that have become trapped on the filter in order to clean same.

Implantable infusion devices configured to improve fill and evacuation procedures.

Needleless connectors are described herein. A needleless connector includes a housing comprising a cavity and a proximal fluid port in fluid communication with the cavity. The connector further includes a filter support disposed at least partially within the cavity. The filter support can include a distal fluid port in fluid communication with the proximal fluid port. The connector further includes a filter disposed circumferentially around the filter support and between the proximal fluid port and the distal fluid port.

An implantable access port including a port housing that defines a fill port cavity and includes a catheter fitting, a filter positioned within the port housing along a delivery flow pathway configured so that fluid injected into the fill port cavity passes through the filter prior to exiting through the catheter fitting, a one-way valve positioned within the port housing along an aspiration flow pathway configured to permit aspirated fluid to flow unfiltered from the catheter fitting to the fill port cavity and prevent injected fluid from flowing unfiltered from the fill port cavity to the catheter fitting, a port cover coupled to the port housing, and a pierceable septum positioned between the fill port cavity and the port cover configured to allow a needle to pierce through the pierceable septum to access the fill port cavity.

A fluid delivery system for delivering fluid to an inner ear of a subject includes a septum configured to be embedded in the inner ear or on a promontory bone of the subject, a spear connector having a needle for insertion into the septum, a catheter in fluid communication with the spear connector, a fixation device configured to secure the septum to the inner ear or the promontory bone.

An implantable drug delivery system includes a middle ear section with a proximal end fixed to a tympanic membrane of a patient, and a distal end that penetrates through a fluid-tight sealed opening into the inner ear. An inner ear section has a proximal end that is connected to the distal end of the middle ear guide member at the sealed opening, and a closed distal end terminating the inner ear holding member some predetermined distance within the cochlea. A hollow interior of the inner ear section is configured for containing a replaceable pharmaceutical agent, and an outer surface is configured to release the pharmaceutical agent from the hollow interior into the inner ear of the patient. The middle ear section and the inner ear section are configured to cooperate for replacing the pharmaceutical agent through the proximal end of the middle ear section to the inner ear section.
