Physically-Configurable External Charger for an Implantable Medical Device with Receptacle in Coil Housing for Electronics Module

Номер: US20170214269A1
Автор: Joshua D. Howard, HOWARD JOSHUA D, Howard Joshua D.
Принадлежит:

A physically-configurable external charger device for an implantable medical device is disclosed, which facilitates the generation of different powers of a magnetic field with reduced heating concerns. A housing which includes an internal charging coil includes a receptacle for holding an electronics module for energizing the charging coil. A cable coupled to the charging coil spans around the edges of the housing and connects to the electronics module when it is retained by the receptacle. In this first configuration, a low-power magnetic field can be produced, as the electronics module is still relatively near the charging coil, and thus may heat to some degree. In a second configuration, the electronics module is removed from the receptacle and extendable from the housing by the length of the cable, and thus a higher-power magnetic field can be produced with reduced heating concerns. 1. An external charger for an implantable medical device , comprising:a housing comprising a receptacle;a charging coil within the housing;an electronics module retainable within and removable from the receptacle; anda cable outside the housing coupled at a first end to the charging coil and connected at a second end to the electronics module,wherein the electronics module is operable to energize the charging coil via the cable to produce a magnetic field to provide power to the implantable medical device.2. The external charger of claim 1 , wherein the receptacle comprises a cup.3. The external charger of claim 1 , wherein the receptacle comprises a wall shaped to mate with a portion of an outer surface of the electronics module.4. The external charger of claim 1 , wherein the housing and the receptacle are formed of the same material.5. The external charger of claim 1 , wherein the electronics module is cylindrical.6. The external charger of claim 1 , wherein the electronics module comprises a circuitry module and a battery module.7. The external charger of claim 6 , wherein the ...

Far-Field Short-Range Radio-Frequency Antenna on the Side of an Implantable Medical Device Case

Номер: US20170281957A1
Автор: Joshua D. Howard, HOWARD JOSHUA D, Howard Joshua D.
Принадлежит:

An Implantable Medical Device (IMD) is disclosed having a bi-directional short-range far-field Radio-Frequency (RF) data antenna, operable in accordance with a short-range RF standard such as Bluetooth for example. The antenna is neither located inside the conductive case of the IMD, nor in the non-conductive header of the IMD that includes the lead connectors. Instead, the antenna is outside of the case, proximate to and generally planar with a flat planar side of the case that faces outward of the patient when the IMD is implanted. Dielectric materials keep the antenna from shorting to the case and to the patient's tissue. Because the antenna is not located within the conductive case, data communications to and from the antenna are less subject to attenuation. Not locating the antenna in the header reserves room for the header's lead connectors, thus simplifying IMD design. 1. An implantable medical device , comprising:a case comprising electronic circuitry inside the case, wherein the case comprises a planar side;a header affixed to the case, wherein the header comprises at least one lead connector configured to receive an electrode lead; anda short-range far-field Radio-Frequency (RF) data antenna outside of the case, wherein the data antenna is proximate to and planar with the planar side of the case.2. The implantable medical device of claim 1 , wherein the case is conductive.3. The implantable medical device of claim 2 , wherein the data antenna comprises a monopole antenna claim 2 , and wherein the conductive case is grounded and acts as a ground plane for the monopole antenna.4. The implantable medical device of claim 2 , further comprising a dielectric material outside the case and between the data antenna and the planar side of the case.5. The implantable medical device of claim 1 , further comprising an electrode feedthrough configured to pass at least one electrode feedthrough pin from the inside to an outside of the case claim 1 , wherein the at least ...

Physically-Configurable External Charger for an Implantable Medical Device with Separable Coil and Electronics Housings

Номер: US20170214268A1
Автор: Joshua D. Howard, HOWARD JOSHUA D, Howard Joshua D.
Принадлежит:

A physically-configurable external charger device for an implantable medical device is disclosed, which facilitates the generation of different powers of a magnetic field but with reduced heating concerns at higher powers. The charger includes an electronics housing having control circuitry and a battery, and a coil housing having a charging coil. A cable connects these two housings. The two housings can be connected in a first physical configuration, and separated in a second physical configuration. In the first physical configuration, a low-power magnetic field can be produced, as the electronics housing is connected to the coil housing, and thus may heat to some degree. In a second physical configuration, the electronics housing is removed and extended from the coil housing, and thus a higher-power magnetic field can be produced with reduced heating concerns. Thus, in this second configuration, the charging rate of the IMD can be increased. 1. An external charger for an implantable medical device , comprising:an electronics housing comprising control circuitry and a battery;a coil housing comprising a charging coil; anda cable coupled at a first end to the charging coil in the coil housing and connected at a second end to control circuitry in the electronics housing,wherein the control circuitry is configured to energize the charging coil via the cable to produce a magnetic field to provide power to the implantable medical device, andwherein the electronics housing and coil housing are configured to be connectable to establish a first configuration for the external charger, and configured to be separable to establish a second configuration for the external charger.2. The external charger of claim 1 , wherein the electronics housing comprises a first flat surface claim 1 , the coil housing comprises a second flat surface claim 1 , and wherein the first and second surfaces are mated when the electronics housing and coil housing are connected in the first ...

Implantable Medical Device with a Stylet Channel

Номер: US20190001136A1
Автор: Hahn Benjamin P., Howard Joshua D., Pianca Anne M.
Принадлежит:

An implantable stimulator device is disclosed preferably having a lead portion and an electronics module integrated and implantable as a single unit, which can enable trial stimulation to occur in a fully implanted solution for a lengthened or unlimited duration. The side of the housing of the electronic module includes a stylet channel which proceeds through the housing at an angle to the implantable stimulator's long axis and bends to proceed through the lead portion along the long axis. The stylet channel can receive a lead stylet to allow the lead portion and the electronics module to be properly positioned within the patient. Because the proximal end of the lead stylet exits the housing of the electronics module at an angle, it provides a handle to steer the lead portion for proper placement within the spinal column. 1. An implantable stimulator device , comprising:an electronics module having a housing with a side parallel to a long axis of the device, the housing containing stimulation circuitry configured to generate electrical stimulation;a lead portion coupled to the housing, the lead portion comprising at least one electrode configured to provide the electrical stimulation to a patient's tissue, wherein the lead portion is parallel to the long axis; anda stylet channel configured to receive a lead stylet that assists with implantation of the implantable stimulator device in a patient, wherein the stylet channel passes through an opening on the side of the housing and through the lead portion.2. The implantable stimulator device of claim 1 , wherein the side of the housing comprises at least a cylindrical portion.3. The implantable stimulator device of claim 1 , wherein the side of the housing comprises at least a flat portion claim 1 , and wherein the side comprises one of first and second parallel major sides of the housing.4. The implantable stimulator device of claim 1 , further comprising a circuit board contained within the housing claim 1 , wherein ...
