Abstract
Embodiments of apparatuses and methods for microfracture (e.g., forming a plurality of microfractures in a bone to encourage cartilage regeneration).
Claims19
An apparatus comprising:
- a guide comprising:
- a platform having a first side, a second side, and a hole extending through the first and second sides, the first side configured to receive a membrane such that the membrane covers an entirety of the hole;
- and
- a guide tube having a first end, a second end, and a channel extending from the first end to the second end, the first end configured to be coupled to the platform such that the hole of the platform and the channel of the guide tube are coaxial;
- and
- an applicator comprising a first end, a second end, and an elongated body extending from the first end to the second end, the elongated body having a length greater than a length of the guide tube, the second end of the applicator configured to push the membrane through the guide tube to an application site in a patient.
3 more elements
A surgical guide apparatus comprising:
- a platform having:
- a first side that includes a bottom surface and one or more sidewalls extending from the bottom surface to define a recess, the recess configured to receive a membrane in a substantially planar configuration;
- a second side, and
- a hole extending along a longitudinal axis through the first and second sides, the longitudinal axis being substantially perpendicular to the bottom surface of the platform such that the membrane is positioned across a plane at the bottom surface of the platform and extending across the hole;
- and
- a guide tube having a first end, a second end, and a channel extending from the first end to the second end, the first end configured to be coupled to the platform such that the hole of the platform is in fluid communication with the channel of the guide tube.
3 more elements
An apparatus comprising:
- a platform for a surgical guide, the platform having a first side, a second side, and a hole extending through the first and second sides, the first side including a recess that is configured to receive a membrane, where the platform is configured to be coupled to a guide tube;
- and
- where the recess defines a planar surface with a minimum transverse dimension that is greater than a maximum transverse dimension of the hole and through which planar surface the hole opens.
A method comprising:
- pushing a membrane through a guide tube to cover a microfracture in an articular surface of a patient with the membrane, where the guide tube extends through the patient's skin such that a distal end of the guide tube is adjacent the microfracture as the membrane exits the guide tube;
- providing a platform with a first side, a second side, a hole extending through the first and second sides, where the first side includes a recess that is configured to receive a membrane, and the membrane is disposed in the recess;
- and
- coupling the platform to a guide tube prior to pushing the membrane through the guide tube.
