Abstract
A device (1) for restraining attached couplers (4, 5) of a percutaneous lead assembly (7). The device (1) comprises a body (14) including two engagement means (8) positioned at opposite ends that engage with the respective couplers (4, 5) to resist disconnection, and an attachment means (9) to attach the device (1) to the outer epidermis of a patient to limit movement of the device (1), when in use.
Claims8
A device for restraining couplers of a percutaneous lead assembly, comprising:
- a resilient body configured for being secured to a patient using a strap, the resilient body including
- a first flange and a second flange located, respectively, at first and second ends of the body, wherein the first and second flanges are configured to securely retain the couplers in the body when the couplers are forcibly pressed into openings formed by the flanges,
- a cover extending between the first and second flanges and shaped to cover the couplers when the couplers are retained in the body, and
- left and right sides of the body, each having an extension and gap extending between the first and second ends, wherein the strap is engaged with the resilient body by the strap passing over the right extension, through the right gap, beneath the cover, through the left gap and over the left extension;
- wherein when the couplers are retained in the resilient body and the device is configured for being secured to a patient via the strap, the connected couplers are protected by being disposed between the strap and the cover;
- and
- wherein the resilient body is configured such that the couplers are forcibly pressed into the openings before the strap can be passed over the respective extensions and through the gaps to dispose the couplers between the strap and the cover.

A method of assembly of a device for restraining and protecting a male coupler and a female coupler of a percutaneous lead, comprising:
- providing a resilient body having a first flange and a second flange located at a respective first and second end of the body, a protective and resilient cover extending from the first flange to the second flange, and a lengthwise extension and gap located at each one of a left and right side of the body and extending between the first and second ends;
- connecting the male coupler to the female coupler;
- after connecting the couplers, engaging the connected couplers to the resilient body including forcibly pressing the male coupler into an opening formed by the first flange and forcibly pressing the female coupler into an opening fowled by the second flange;
- and
- after the connected couplers are engaged to the resilient body, connecting the resilient body to a strap by passing the strap over the right extension, through the right gap, beneath the protective cover, through the left adjacent gap and then over the left extension;
- wherein when the device is fully assembled the male and female couplers are encapsulated by the strap, protective cover and left and right flanges;
- wherein the couplers are forcibly pressed into the openings before the strap can be passed over the respective extensions and through the gaps to dispose the couplers between the strap and the cover.
