Abstract
The present invention relates to an implantable device (1) comprising: —an ultrasonic unit (11) which includes an electric connection terminal, —a support plate (12) which includes a through-opening for the connection terminal to pass through, and —an attachment piece (13) which can cooperate with the connection terminal, the attachment piece (13) including a collar for pressing the support plate (12) against the ultrasonic unit (11) when the ultrasonic unit (11), the support plate (12) and the attachment piece (13) are joined.
Core Innovation
The invention relates to an implantable device configured for positioning at an aperture provided in the braincase of a patient. The implantable device comprises a support plate with a through-opening, an ultrasonic unit mounted on the support plate, and an electric connection terminal attached to the housing of the ultrasonic unit.
The ultrasonic unit includes a housing with a bottom, side walls and an upper face, and a plurality of transducers disposed in the housing for the generation of ultrasonic waves for treating a brain condition. The electric connection terminal includes a pin projecting outward from the housing perpendicular to the bottom and oriented from the bottom towards the upper face, and the pin includes a blind hole into which an end of at least one needle is intended to be introduced to electrically connect the ultrasonic unit to electrical connection means.
The implantable device further includes an attachment piece having a conduit receiving at least a portion of the pin and a peripheral collar extending perpendicularly to a longitudinal axis of the conduit. The peripheral collar contacts the second face of the support plate to press the support plate against the housing when the ultrasonic unit, support plate and attachment piece are joined, with modular assembly using three independent components.
Claims Coverage
The provided independent claims cover 4 inventive features centered on an implantable ultrasonic device and a corresponding system for imaging and/or treatment, with structural connection between a housing-mounted ultrasonic unit and needle-based electrical connection means, together with a mechanically joining attachment piece.
Needle-linked pin terminal with blind hole through support plate
The connection terminal comprises a pin projecting outwards from the housing in a direction perpendicular to the bottom and oriented from the bottom towards the upper face of the housing, wherein the pin includes a blind hole into which an end of the at least one needle is intended to be introduced to electrically connect the ultrasonic unit to the electrical connection means, the support plate comprises a through-opening for the pin to pass through.
Attachment piece with conduit and peripheral collar pressing support plate against housing
The implantable device further comprises an attachment piece including a conduit wherein at least a portion of the pin is received by the conduit, and a peripheral collar extending perpendicularly to a longitudinal axis of the conduit, wherein the peripheral collar contacts the second face of the support plate to press the support plate against the housing when the ultrasonic unit, the support plate and the attachment piece are joined.
Ultrasonic unit with housing-mounted transducers for treating brain condition
An ultrasonic unit mounted on the support plate, said ultrasonic unit comprising a housing including a bottom, at least one side wall and an upper face opposite the bottom, a plurality of transducers disposed in the housing for the generation of ultrasonic waves for treating a brain condition, and an electric connection terminal attached to the housing for connecting the ultrasonic unit to a remote-control unit via electrical connection means including at least one needle.
Brain imaging and/or treatment system including control unit and needle-based electrical connection means
A system for imaging and/or treatment of a brain tissue, the system including a control unit and electrical connection means, wherein the system further comprises an implantable device configured for positioning at an aperture provided in the braincase of a patient, the implantable device comprising an ultrasonic unit with transducers for the generation of ultrasonic waves for treating a brain condition and an electric connection terminal for connecting the ultrasonic unit to the control unit via the electrical connection means including at least one needle, wherein the connection terminal comprises a pin with a blind hole intended to receive an end of the at least one needle, and the support plate comprises a through-opening for the pin to pass through.
Across the independent claims, the coverage centers on an implantable ultrasonic unit having transducers for treating a brain condition and a housing-mounted pin terminal with a blind hole that mates with needle-based electrical connection means through a support-plate through-opening. The mechanical joining is defined by an attachment piece with a conduit receiving the pin and a peripheral collar contacting the support plate to press the support plate against the housing when joined, within an imaging and/or treatment system that includes a control unit.
Stated Advantages
Improved connection safety via the needle-to-terminal blind hole with countersink.
Reduced risk of connection-related damage to the electronic board due to collar protection and force distribution limiting support plate deformation.
Modular assembly using three independent components.
Documented Applications
A system for imaging and/or treatment of brain tissue, including an implantable device positioned at an aperture in the braincase and connected to a remote-control unit/control unit via needle-based electrical connection means.
