Device Description
The Bionix T-Form Extremity Immobilizer is intended to be used for the positioning and re-positioning of patients undergoing or receiving a course of external beam radiation therapy for the treatment of cancer and other diseases.
The T-Form Extremity Immobilizer from Bionix Development Corp. consists of a thermoformed patient support device with attachment areas for accessories. The T-Form Extremity Immobilizer is thermoformed from an ABS plastic material so that the resulting contoured shell is lightweight and thin-walled, providing low attenuation for unobstructed passage of the radiation therapy beam. The T-Form Extremity Immobilizer is specifically designed for immobilization of the upper and lower extremities.
The T-Form Extremity Immobilizer has a generally rectangular shape, with pre-formed areas that allows,the device to be securely attached to the treatment couch tabletop. Specifically, there are pre-formed depressions with threaded holes that allow the T-Form Extremity Immobilizer to screw onto an attachment bar that can lock onto the treatment couch tabletop. These pre-formed areas can be found on both the top and side of the device, allowing the T-Form Extremity Immobilizer to be used in either a longitudinal or transverse orientation to allow greater flexibility in patient positioning. This allows the T-Form Extremity Immobilizer to be repeatedly located in the same position on the treatment couch tabletop for each therapy session.
The T-Form Extremity Immobilizer has a central thermoformed depression to allow the use of optional vacuum cushions as part of the patient immobilization process. Vacuum cushions contain expanded polystyrene beads in an airtight vinyl bag, with a valve for attachment to a vacuum pump. In practice, the patient's extremity is positioned on the bag which is then evacuated using the vacuum pump. As the bag is evacuated, the polystyrene beads form a rigid cushion that accurately conforms to the contours of the patient's extremity, and also to the sides of the thermoformed depression. The latter allows the vacuum cushion to locate reproducibly onto the board, while the patient's extremity can be reproducibly located into the pocket formed into the vacuum cushion.
Attachment points for standard low-melt thermoplastic (used to restrain patients undergoing radiation therapy) are provided for use in immobilizing the patient's extremities. A simple mechanical interlocking system allows the attachment of the lowmelt thermoplastic to the T-Form Extremity Immobilizer. Low-melt thermoplastic has the property of becoming soft and pliable when warm so that it can be stretched over and molded to the contoured shape of an object, in this case the patient. As it cools, it becomes rigid, and retains the object's shape. For the T-Form Extremity Immobilizer two non-adherent plastic handles are used to hold the low-melt thermoplastic. Simple screwtightened clamps mounted on the surface of the T-Form Extremity Immobilizer are used to secure the non-adherent plastic handles to the board. The low-melt thermoplastic sheet is stretched over the patient's extremity in its pliable form; once molded to the patient's anatomy, the customized low-melt thermoplastic sheet can be placed over the patient and "locked down" to the T-Form Extremity Immobilizer to ensure proper positioning for every therapy session.
The Bionix T-Form Extremity Immobilizer has a thermoformed ABS shell that displays minimal attenuation of the radiotherapy beam. This is due primarily to the fact that the thermoformed shell is relatively thin. The device has an open, air filled core that is radiolucent. The resulting structure provides strength and rigidity, and is ideal for producing a device that reproducibly positions patients and yet does not interfere with the administration of therapeutic radiation. Patient positioning devices with this type of structure are common in radiation therapy. They come in many varieties and are manufactured by several companies; examples including Civco Medical Solutions.

Background and Principles of Operation.
The Bionix T-Form Extremity Immobilizer is intended to be used for the positioning and re-positioning of patients undergoing or receiving a course of external beam radiation therapy for the treatment of cancer and other diseases.
The T-Form Extremity Immobilizer from Bionix Development Corp. consists of a thermoformed patient support device with attachment areas for accessories. The T-Form Extremity Immobilizer is thermoformed from an ABS plastic material so that the resulting contoured shell is lightweight and thin-walled, providing low attenuation for

unobstructed passage of the radiation therapy beam. The T-Form Extremity Immobilizer is specifically designed for immobilization of the upper and lower extremities.
The T-Form Extremity Immobilizer has a generally rectangular shape, with pre-formed areas that allows,the device to be securely attached to the treatment couch tabletop. Specifically, there are pre-formed depressions with threaded holes that allow the T-Form Extremity Immobilizer to screw onto an attachment bar that can lock onto the treatment couch tabletop. These pre-formed areas can be found on both the top and side of the device, allowing the T-Form Extremity Immobilizer to be used in either a longitudinal or transverse orientation to allow greater flexibility in patient positioning. This allows the T-Form Extremity Immobilizer to be repeatedly located in the same position on the treatment couch tabletop for each therapy session.
The T-Form Extremity Immobilizer has a central thermoformed depression to allow the use of optional vacuum cushions as part of the patient immobilization process. Vacuum cushions contain expanded polystyrene beads in an airtight vinyl bag, with a valve for attachment to a vacuum pump. In practice, the patient's extremity is positioned on the bag which is then evacuated using the vacuum pump. As the bag is evacuated, the polystyrene beads form a rigid cushion that accurately conforms to the contours of the patient's extremity, and also to the sides of the thermoformed depression. The latter allows the vacuum cushion to locate reproducibly onto the board, while the patient's extremity can be reproducibly located into the pocket formed into the vacuum cushion.
Attachment points for standard low-melt thermoplastic (used to restrain patients undergoing radiation therapy) are provided for use in immobilizing the patient's extremities. A simple mechanical interlocking system allows the attachment of the lowmelt thermoplastic to the T-Form Extremity Immobilizer. Low-melt thermoplastic has the property of becoming soft and pliable when warm so that it can be stretched over and molded to the contoured shape of an object, in this case the patient. As it cools, it becomes rigid, and retains the object's shape. For the T-Form Extremity Immobilizer two non-adherent plastic handles are used to hold the low-melt thermoplastic. Simple screwtightened clamps mounted on the surface of the T-Form Extremity Immobilizer are used to secure the non-adherent plastic handles to the board. The low-melt thermoplastic sheet is stretched over the patient's extremity in its pliable form; once molded to the patient's anatomy, the customized low-melt thermoplastic sheet can be placed over the patient and "locked down" to the T-Form Extremity Immobilizer to ensure proper positioning for every therapy session.
The Bionix T-Form Extremity Immobilizer has a thermoformed ABS shell that displays minimal attenuation of the radiotherapy beam. This is due primarily to the fact that the thermoformed shell is relatively thin. The device has an open, air filled core that is radiolucent. The resulting structure provides strength and rigidity, and is ideal for producing a device that reproducibly positions patients and yet does not interfere with the administration of therapeutic radiation. Patient positioning devices with this type of structure are common in radiation therapy. They come in many varieties and are manufactured by several companies; examples including Civco Medical Solutions.

In clinical practice, the Bionix T-Form Extremity Immobilizer is secured to the therapy couch tabletop by attachment to a lock-down bar. The patient's extremity is positioned on the T-Form Extremity Immobilizer as desired, either directly onto the board or with the use of a vacuum cushion that has been evacuated to conform to the patient's anatomy. Low-melt thermoplastic is heated, and then draped in its warm, pliable state over the patient's extremity, and then secured to the T-Form Extremity Immobilizer using the screw-down clamps. When it cools, the low-melt thermoplastic becomes rigid and retains the shape of the patient's extremity, allowing it to be positioned and re-positioned securely during the radiation therapy regimen. Radiation therapy is then administered in the usual fashion.
Comparison to Predicate Device:
j
This product is similar in design and function to existing patient positioning devices currently in use as accessories to radiation therapy systems. One such device is the Multifix, manufactured and legally marketed by Civco Medical Solutions of Orange City, Iowa. The Multifix immobilization system is used to position and immobilize the upper and lower extremities during a course of radiation therapy. Another such device is the HipFix, also manufactured and legally marketed by Civco Medical Solutions of Orange City, Iowa. The HipFix hip and pelvis immobilization system is used to position and immobilize the hips and lower extremities during a course of radiation therapy.
The Multifix has a base-plate that may be made of acrylic sheet, or preferably, from carbon fiber/foam composite material for enhanced radiolucency. Such structures are commonplace in radiation therapy positioning products to provide rigidity and support while at the same time minimizing attenuation of the radiation therapy beam. The baseplate has four sets of indexed holes allowing the extremity to be reproducibly positioned in either a straight or bent position. The base-plate is also provided with attachments to a lock-down bar so that the device can be indexed to the treatment couch tabletop.
The HipFix base-plate is constructed of a carbon fiber/foam composite material for enhanced radiolucency. The HipFix base-plate also features a cutout treatment window, again to enhance radiolucency in the treatment field. The HipFix base-plate is provided with attachments to a lock-down bar so that the device can be indexed to the treatment couch tabletop.
In the T-Form Extremity Immobilizer by Bionix Development Corporation, a thermoformed ABS plastic shell is used instead of a carbon fiber/foam composite material to provide radiolucency and rigidity. The resulting device is lightweight and thin-walled, providing low attenuation for unobstructed passage of the radiation therapy beam. Using a thermoformed plastic design makes a cut-out treatment window unnecessary for the Bionix T-Form Extremity Immobilizer.
In the Multifix device, several small sheets of low-melt thermoplastic are molded to the extremity and secured by locking into one of the indexing holes on the base-plate.

T-Form Extremity Immobilizer- Premarket Notification Submission
The low-melt thermoplastic provides immobilization and isocentric positioning of the target limb.
The HipFix immobilization system utilizes a single sheet of low-melt thermoplastic over the abdomen and pelvis region to provide immobilization and enhance fixed fiducial targeting. A vacuum cushion can be integrated to the HipFix for added comfort and repositioning accuracy.
In similar fashion, the Bionix T-Form Extremity Immobilizer uses a sheet of low-melt thermoplastic to conform to the patient's extremity to provide immobilization and ensure proper positioning for every therapy session. The T-Form Extremity Immobilizer also has a thermoformed depression to facilitate the positioning of optional vacuum cushions as part of the patient immobilization process.
Conclusion:
i
The similarity of design, features, radiolucency, and function indicate that the T-Form Extremity Immobilizer from Bionix Development Corporation will perform as well as the legally marketed Multifix and HipFix immobilization devices from Civco Medical Solutions for the intended use of positioning and re-positioning of patients undergoing or receiving a course of external beam radiation therapy for the treatment of cancer and other diseases.
