A medical device includes an operating member, a hub, and an end effector. The operating member includes an actuation portion. The hub includes a channel receiving the actuation portion of the operating member. The actuation portion of the operating member moves within the channel. The end effector is movable between a closed configuration and an open configuration. Distal extension of the operating member transitions the end effector to the open configuration, and proximal retraction of the operating member transitions the end effector to the closed configuration. The medical device is formed through an additive manufacturing process.

Medical devices and related methods

Embodiments of the present disclosure relate to implantable medical device (IMD) enclosures. In an exemplary embodiment, an IMD comprises: a housing comprising an open end and a header defining a cavity and comprising at least one conduit through a wall of the header, wherein the header is formed from a non-conductive material. Further, the IMD comprises a coupling member comprising a flange, wherein the flange is configured to be received by the open end of the housing and wherein the flange and the open end of the housing at least partially overlap along an axial direction of the IMD when the flange is received by the open end. Additionally, the IMD comprises an electrode arranged on an outer surface of the header and a feedthrough coupled to the electrode and extending through the conduit of the header, wherein the feedthrough is configured to be coupled to internal circuitry housed within the IMD. Further, the IMD comprises a ring forming a hermetic seal between the coupling member and the header.

IMD enclosure formed using dielectric materials incorporating feedthru(s)

A method of manufacturing an elevator of a medical device comprises using an additive manufacturing method, forming a pivot portion at a proximal end of the elevator. The pivot portion tapers proximally such that a proximalmost end of the elevator is thinner than more distal portions of the pivot portion. The method further comprises using the additive manufacturing method, forming a body of the elevator that is distal to the pivot portion. The elevator body includes a surface configured to contact an instrument inserted in a working channel of the medical device.

Elevator components for medical devices

An implantable medical device may include a plurality of electrical components connected to form operational circuitry, a canister shaped for housing the operational circuitry, and a dampening layer configured to reduce internal motion between the operational circuitry and at least one of a plurality of additional component within the canister, the dampening layer selectively disposed over the operational circuitry but not over the at least one additional component, the dampening layer providing electrical isolation to the operational circuitry, the dampening layer comprising a moldable material in direct contact with an inner surface of the canister. Methods of manufacturing such a medical device are also disclosed.

Implantable medical device with relative motion control

Disclosed herein is an implantable medical device including a housing, a header, a connector port, and a collet assembly. The header can be arranged with the housing. The connector port can be arranged within the header and configured to couple an implantable lead to the header. The collet assembly can be arranged within the connector port and configured to frictionally engage a portion of the implantable lead and to secure the implantable lead with the header in response to insertion of the portion of the implantable lead into the connector port.

Automatic lead lock for an implantable medical device

Various aspects of the present disclosure are directed toward apparatuses, systems and methods for connecting a lead to an implantable medical device. The apparatuses, systems and methods may include a clamp arranged within a connector port configured to secure the lead with a header in response to frictional engagement between a portion of the implantable lead and the clamp.

Lead retention method

Systems and methods to couple electrical contacts of a header of a medical device to respective feedthrough pins of a connector block of a medical device housing using a preformed wire are disclosed. The preformed wire can include a proximate portion comprising a number of turns shaped to engage a feedthrough pin. The number of turns of the preformed wire, once engaged with the feedthrough pin, can physically separate a major portion of the preformed wire from the connector block and the housing. The major portion of the preformed wire can be shaped to route a distal portion of the preformed wire to a first electrical contact of the header when the proximate portion of the preformed wire engages the feedthrough pin.

Preformed wire routes

Embodiments of the present disclosure relate to implantable medical devices. According to an exemplary embodiment, a method for forming an electrode on an implantable medical device (IMD), comprises forming a nonconductive body comprising a well having a bottom surface and at least one side surface extending from the bottom surface. The method further comprises forming a conduit through the bottom surface and inserting the nonconductive body into an opening in an external surface of the IMD. The method also comprises depositing conductive material into the well and coupling the conductive material to a circuit of the IMD via the conduit through the bottom surface of the well.

Implantable medical device including electrodes formed therein

A device for aseptic delivery of biological material from a vial includes a tubular barrel, a filter assembly, and a dispersion assembly. The dispersion assembly is at least partially disposed within the tubular barrel. The dispersion assembly includes a dispersion element, a piston, and a one-way valve. The dispersion element is in fluid communication with the vial to disperse the biological material from the vial. The piston is disposed at the distal end of the dispersion assembly and is in sealing contact with the tubular barrel. The one-way valve forms a fluid passageway in fluid communication with the dispersion element and the tubular barrel. The one-way valve is configured to allow a flow of the dispersed biological material from the dispersion element, through the fluid passageway, and into the tubular barrel, and to prevent a flow of the dispersed biological material from the tubular barrel into the dispersion assembly.
