US 12,746,044 B2 · Medical implant

Abstract

Systems, devices, and methods for stabilization of bones and/or joints are disclosed. A medical implant may be inserted into a treatment site, such as an interspinous process space. The implant may have an outer body, an inner body coupled to the outer body, distal wings coupled to the inner body, proximal wings coupled to the outer body, and a threaded screw coupled to the inner body and outer body. The threaded screw may be configured to couple to a driver head of an insertion tool and the outer body may be configured to couple to an attachment member of an insertion tool. Actuating the insertion tool may actuate the threaded screw to thereby transition the proximal wings and the distal wings from a closed configuration to a deployed configuration, and from a deployed configuration to a clamped configuration.

Dependent claims

A medical implant for insertion at a treatment site, comprising:

an outer body defining a longitudinal axis extending through a proximal end of the outer body and a distal end of the outer body;
an inner body
a threaded screw operatively coupled to the outer body and having a first threading and a second threading,
wherein the first threading threads in an opposite direction relative to the second threading;
a carrier coupled to the threaded screw;
ramps defined by the medical implant,
wherein the inner body comprises the ramps;
one or more proximal wings operatively coupled to the carrier;
and
one or more distal wings,
wherein actuation of the threaded screw simultaneously pivots the one or more proximal wings between a closed position and a deployed position and pivots the one or more distal wings between a closed position and a deployed position,
wherein continued actuation of the threaded screw distally translates the one or more proximal wings from the deployed position to a clamped position to engage the one or more proximal wings with bone or tissue at the treatment site.

A system configured to insert a medical implant into a treatment site, the system comprising:

the medical implant, comprising:
an outer body defining a longitudinal axis extending through a proximal end of the outer body and a distal end of the outer body;
an inner body,
wherein the inner body comprises ramps;
a threaded screw operatively coupled to the outer body and having a first threading and a second threading,
wherein the first threading threads in an opposite direction relative to the second threading;
one or more proximal wings;
and
one or more distal wings;
an insertion tool, comprising:
an outer shaft coupled to an outer grip;
a handle operatively coupled to the outer grip such that the outer shaft couples to the handle;
an inner shaft, the outer shaft receiving at least a portion of the inner shaft;
an attachment member coupled to the inner shaft,
wherein the attachment member removably couples to the outer body of the medical implant to attach the medical implant to the insertion tool;
and
an inner rod having a distal end and a proximal end,
wherein the inner shaft receives at least a portion of the inner rod,
wherein the distal end of the inner rod comprises a driver head and the proximal end of the inner rod comprises a control,
wherein the threaded screw is configured to receive the driver head,
wherein operation of the control rotates the driver head to actuate the threaded screw,
wherein rotation of the driver head rotates the threaded screw to transition the one or more proximal wings and the one or more distal wings between a closed position and a deployed position.

A method of inserting a medical implant into a treatment site, the method comprising:

providing the medical implant, the medical implant comprising:
an outer body defining a longitudinal axis extending through a proximal end of the outer body and a distal end of the outer body;
a threaded screw operatively coupled to the outer body and having a first threading and a second threading,
wherein the first threading threads in an opposite direction relative to the second threading;
a proximal carrier coupled to the threaded screw;
ramps defined by the medical implant;
one or more proximal wings operatively coupled to the proximal carrier;
and
one or more distal wings,
wherein the one or more proximal wings and the one or more distal wings are in a closed position;
attaching an insertion tool to the medical implant,
inserting a portion of the medical implant into the treatment site;
and
actuating the insertion tool in a first direction to transition the medical implant from a closed configuration to a deployed configuration,
wherein actuating the insertion tool in a first direction comprises rotating a portion of the insertion tool in the first direction to pivot the one or more distal wings and the one or more proximal wings from the closed configuration to the deployed configuration,
wherein rotating the portion of the insertion tool in the first direction rotates the threaded screw to thereby pivot the one or more distal wings and the one or more proximal wings from the closed configuration to the deployed configuration, the rotation of the threaded screw causing at least a portion of each proximal wing of the one or more proximal wings to contact the ramps to thereby pivot the one or more proximal wings from the closed configuration to the deployed configuration.
