Intended Use

SJM Neurostimulation Systems are indicated for spinal cord stimulation (SCS) in the management of chronic pain of the trunk and limbs, either as the sole mitigating agent, or as an adjunct to other modes of therapy used in a multidisciplinary approach. The Swift-Lock™ anchor is intended to be an accessory to the leads component of the spinal cord stimulation (SCS) system, functioning to secure compatible St. Jude Medical™ (SJM) leads to the fascia or interspinous/supraspinous ligament.

Device Story

Single-use mechanical anchor for spinal cord stimulation (SCS) leads; secures leads to fascia or interspinous/supraspinous ligament during implantation. Device consists of male and female components joined by stainless steel pin; features rotating midsection to lock lead in place via mechanical gripping. Includes visual/tactile aids: raised eyelets, indicating arrows, 1 cm depth indicator; distal strain relief cuts; tapered tip for insertion. Used by physicians during surgical implantation. Enhances lead-to-anchor holding force; prevents lead migration; improves patient outcomes by maintaining stimulation lead stability.

Clinical Evidence

Bench testing only. Verification and validation activities confirmed device meets predetermined design and performance specifications. Mechanical testing demonstrated that design differences do not adversely affect safety or effectiveness.

Technological Characteristics

Mechanical anchor; materials: PEEK (interlocking core), Silicone/BaSO4 (sleeve), stainless steel (pin). Features: rotating locking mechanism, strain relief cuts, depth indicators. Single-use. Sterilization: EtO. No software or electronic components.

Indications for Use

Indicated for patients requiring spinal cord stimulation (SCS) for management of chronic pain of the trunk and limbs, either as sole therapy or as an adjunct in a multidisciplinary approach.

Regulatory Classification

Identification

An implanted spinal cord stimulator for pain relief is a device that is used to stimulate electrically a patient's spinal cord to relieve severe intractable pain. The stimulator consists of an implanted receiver with electrodes that are placed on the patient's spinal cord and an external transmitter for transmitting the stimulating pulses across the patient's skin to the implanted receiver.

#### Predicate Device: 5.1

The subject device is substantially equivalent to the Swift-Lock ™ Anchor (K092371) cleared on December 23, 2009

#### 5.2 Device Description:

The Swift-Lock™ Anchor is a single-use device used to attach the implanted lead to the fascia or interspinous ligament via suturing. The anchor is made up of male and female components that are partially over-molded with silicone rubber and ioined by a stainless steel pin. The Swift-Lock™ Anchor has a mechanical mechanism to secure the lead body to the anchor. This is accomplished by a rotating midsection where the male and female components align and lock into place. When properly executed, the anchor securely holds the lead into place enhancing the lead to anchor holding force. The Swift-Lock™ Anchor has several visual and tactile features such as; raised eyelets, indicating arrows, and a 1 cm depth indicator that aid the physician in inserting the anchor and securing the anchor to the lead. The Swift-Lock™ Anchor also has strain relief cuts in the distal end column for improved strain relief and increased flexibility and a thinner tapered distal tip for ease of insertion.

#### 5.3 Indications for Use:

SJM Neurostimulation Systems are indicated for spinal cord stimulation (SCS) in the management of chronic pain of the trunk and limbs, either as the sole mitigating agent, or as an adjunct to other modes of therapy used in a multidisciplinary approach.

The Swift-Lock™ anchor is intended to be an accessory to the leads component of the spinal cord stimulation (SCS) system, functioning to secure compatible St. Jude Medical™ (SJM) leads to the fascia or interspinous/supraspinous ligament.

#### Summary of Technological Characteristics of the New Device 5.4 Compared to the Predicate Device:

The Swift-Lock™ Anchor has the same intended use and indications for use as the predicate device. The Swift-Lock™ Anchor functions in the same manner as the predicate device in that it is used to secure SCS leads into place during implantation. The mechanism by which this happens is the same. The anchor slides over an SCS lead and is secured to the fascia or interspinous/supraspinous ligament via suturing. This function is the same for the predicate device. The Swift-Lock ™ Anchor has the same operating principle as the predicate device in that after the device is slid into place along the SCS lead, the anchor is then turned and locked into position using the same mechanical principle of "gripping" the lead to the anchor.

The predicate device and the subject device have the same interlocking core components designed as male and female parts joined together by a stainless steel pin. The interlocking core components incorporate a plastic material formulation called PEEK. The indicating arrows are laser engraved on the male and female parts and the core is also molded with suture grooves for extra suturing purposes if desired. These two interlocking core components are partially over molded with Silicone/BaSO4 sleeves in order to provide distal strain relief.

The Swift-Lock™ Anchor is comprised of identical materials and is processed by identical manufacturing methods as the predicate device cleared under K092371. The predicate device and the subject device are both single use devices, have the same cylindrical shape and have the same base material for the outer sleeve which is a formulation of Silicone with Barium sulfate.

All other technological characteristics of the Swift-Lock™ Anchor were not affected by the modifications to the predicate device including, Sterilization, EtO Residuals, Packaging, Shelf Life, and Biocompatibility. Where differences exist between the subject device and the predicate device design and labeling, performance testing and labeling review demonstrated that these differences do not adversely affect the safety and effectiveness of the subject device.

#### 5.5 Non-Clinical Test Summary:

Completion of all verification and validation activities demonstrated that the subject device meets the predetermined design and performance specifications. The testing included mechanical testing to confirm that the minor differences in the design do not adversely affect the safety and effectiveness of the subject device.

#### 5.6 Conclusion:

St. Jude Medical considers the Swift-Lock™ Anchor to be substantially equivalent to the predicate device listed above. This conclusion is based upon the device similarities in design, technological characteristics, principle of operation, indications for use and intended use.
