A spinal distraction system includes a distraction rod having a first end and a second end, the first end being configured for affixation to a subject's spine at a first location, the distraction rod having a second end containing a recess having a threaded portion disposed therein. The system further includes an adjustable portion configured for affixation relative to the subject's spine at a second location remote from the first location, the adjustable portion comprising a housing containing a magnetic assembly, the magnetic assembly affixed at one end thereof to a lead screw, the lead screw operatively coupled to the threaded portion. A locking pin may secure the lead screw to the magnetic assembly. An O-ring gland disposed on the end of the housing may form a dynamic seal with the distraction rod.

Adjustable implant system

A device for the non-invasive sensing of the length of an implantable medical device includes an implantable medical device having first and second portions moveable relative to one another and a layer of resistive material disposed on one of the first and second portions. A contact is disposed on the other of the first and second portions, the contact being in sliding contact with the layer of resistive material upon relative movement between the first and second portions. A circuit is configured to measure the electrical resistance along a path including a variable length region of the layer of resistive material and the contact. The electrical resistance can then be converted into a length.

Devices and methods for non-invasive implant length sensing

A system for surgical planning and assessment of spinal deformity correction is provided that has a spinal imaging system and a control unit. The spinal imaging system is configured to collect at least one digitized position of one or more vertebral bodies of a subject. The control unit is configured to receive the at least one digitized position, and calculate, based on the at least one digitized position, an optimized posture for the subject. The control unit is configured to receive one or more simulated spinal correction inputs, and based on the inputs and optimized posture, predict an optimal simulated postoperative surgical correction.

The disclosure describes systems and methods for altering bone sections in a patient. In one embodiment, a system may include an intramedullary implant including: a housing configured to be secured to a first section of bone, where the housing may include one or more shaft engaging grooves axially extending along an inner surface thereof; a distraction shaft configured to be secured to a second section of bone, where the distraction shaft may include one or more grooves axially extending along an inner surface thereof. The system may further include an actuator disposed within the housing and operably coupled to the distraction shaft, and in response to rotation of the actuator, the one or more grooves of the distraction shaft may engage with the one or more shaft engaging grooves of the housing, causing axial displacement of the distraction shaft relative to the housing.

System and method for altering rotational alignment of bone sections

A delivery apparatus for a medical device can include a handle, a shaft, a plurality of sleeves, and a suture. The shaft includes a proximal end portion coupled to the handle and is configured to be disposed outside of a patient's body during an implantation procedure and a distal end portion configured to be disposed inside a patient's body during the implantation procedure. Each of the sleeves includes a connection portion coupled to the distal end portion of the shaft and a receiving portion configured to receive an apex of a stent or a prosthetic heart valve. The suture extends through the shaft and the sleeves and is configured for releasably securing the stent or the prosthetic heart valve to the receiving portions of the sleeves.

Suture deployment of prosthetic heart valve

A steerable guidewire. The steerable guidewire is fabricated includes an outer tube, an inner tube, a hub, and a distal articulating region. The steerable guidewire hub can be removed to permit advancement of catheters over its proximal end followed by re-attachment of the hub to permit deflection of the distal end of the steerable guidewire.

Steerable guidewire and method of use

An external adjustment device includes at least one permanent magnet configured for rotation about an axis with a first handle extending linearly at a first end of the device and a second handle at a second end of the device, the second handle extending in a direction substantially off axis to the first handle. The external adjustment device further includes a motor mounted inside the first handle and a first button located in the proximity to one of the first handle or the second handle, the first button configured to be operated by the thumb of a hand that grips the one of the find handle or second handle. The first button is configured to actuate the motor causing the at least one permanent magnet to rotate about the axis in a first direction.

External adjustment device for distraction system

A distraction system includes a distraction rod having one end configured for affixation to at a first location on patient. The system further includes an adjustable portion configured for placement in the patient at a second location, the adjustable portion comprising a housing containing a magnetic assembly comprising a magnet, the magnetic assembly secured to a threaded element that interfaces with an opposing end of the distraction rod. The system includes a magnetically permeable member in proximity to the magnetic assembly and covering an arc of less than 360° of the adjustable portion.

Systems and methods treat a heart valve using a magnetically adjustable annuloplasty ring attached to or near a cardiac valve annulus. A changing magnetic field may be used to selectively increase or decrease a circumference of, or otherwise modify the shape of, the implanted annuloplasty ring. The adjustable annuloplasty ring includes a tubular body member, one or more adjustable members, and an internal magnet within the tubular body member. The tubular body member and the one or more adjustable members form a ring shape. The internal magnet is configured to rotate in response to a rotating external magnetic field. The internal magnet is coupled to the one or more adjustable members to change a dimension of the ring shape as the internal magnet rotates. A system for treating a heart valve may include an external adjustment device having one or more external magnets to generate the rotating external magnetic field.

A system for non-invasively adjusting the curvature of a spine includes a housing having a first end and a second end, a first rod having a first end telescopically disposed within a cavity of the housing along a first longitudinal axis at the first end of the housing and having a first threaded portion extending thereon, and a second end configured to be coupled to a first portion of a spinal system of a subject, a second rod having a first end telescopically disposed within the cavity along a second longitudinal axis at the second end of the housing and having a second threaded portion extending thereon, and a second end configured to be coupled to a second portion of the spinal system of the subject, a driving member rotatably disposed within the cavity and configured to be activated from a location external to the body of the subject.

Systems and methods for vertebral adjustment

A device for the non-invasive sensing of the length of an implantable medical device includes animplantable medical device having first and second portions moveable relative to one another and a layer of resistive material disposed on one of the first and second portions. A contact is disposed on the other of the first and second portions, the contact being in sliding contact with the layer of resistive material upon relative movement between the first and second portions. A circuit is configured to measure the electrical resistance along a path including a variable length region of the layer of resistive material and the contact. The electrical resistance can then be converted into a length.

A method of positioning an external adjustment device relative to a patient includes placing a magnetic viewing sheet adjacent to a patient and identifying the location of an implanted magnetic assembly using the magnetic viewing sheet by visualizing a magnetic image of the implanted magnetic assembly in the magnetic viewing sheet. The external adjustment device is placed on the patient adjacent to the location where the magnetic image was located.
