Abstract
The devices, systems, and methods herein described provide uniform biomaterial delivery to produce robust adhesion between an implant (e.g., an implantable screw) and a bone tissue. Furthermore, the devices, systems, and methods of the disclosure overcome challenges associated with the repair of weak or deficient bone and augmentation using injected biomaterials.
Claims370
A device comprising a unitary body comprising from a proximal end to a distal end:
- a proximal region, a central region, and a distal region, wherein the central region joins the proximal region to the distal region, and wherein:
- a) the device comprises an internal channel extending longitudinally through the proximal, central, and distal regions;
- b) the proximal region comprises an opening to the internal channel and a plurality of circumferentially disposed and compressible wings;
- c) the central region comprises an expandable body configured to radially expand;
- and
- d) the distal region comprises an opening to the internal channel and internal threads.
The system of 119, wherein the distal region of the connector is configured to be inserted into the internal channel of the device at the proximal region thereof by aligning the alignment marker of the connector with the alignment marker of the device.
The method of 153 or 154, comprising uncoupling the biomaterial dispenser and/or the connector from the proximal region of the device after the biomaterial is introduced to the internal channel of the device.
An extraction tool comprising from a proximal end to a distal end:
- a proximal region, a central region, and a distal region wherein:
- a) the proximal region comprises a grip handle;
- b) the central region comprises a pivot joint;
- c) the distal region comprises a pair of nubs;
- and
- d) two members pivotally coupled by the pivot joint.
A device comprising a unitary body comprising from a proximal end to a distal end:
- a proximal region, a central region, and a distal region, wherein the central region joins the proximal region to the distal region, and wherein:
- a) the device comprises an internal channel extending longitudinally through the proximal, central, and distal regions;
- b) the proximal region comprises a compressible body and an opening to the internal channel;
- c) the central region comprises i) a plurality of openings and ii) an expandable and/or compressible body configured to radially expand or compress, wherein the expandible and/or compressible body comprises a plurality of longitudinal segments;
- and
- d) the distal region comprises an opening to the internal channel.
A device comprising a unitary body comprising a proximal end and a distal end, wherein:
- a) the unitary body comprises an expandable and/or compressible body configured to radially expand or compress, wherein unitary body comprises a rolled surface having an internal channel extending longitudinally from the proximal end to the distal end;
- b) the unitary body comprises a plurality of openings;
- c) the internal channel comprises an internal protrusion and/or internal thread;
- d) the proximal end comprises an opening to the internal channel;
- and
- e) the distal end comprises an opening to the internal channel.
