## Abstract

Components and associated methods of manufacture or assembly and/or use for bone and joint stabilization devices or systems are described. The components include features for device introduction, attaching a distal anchoring foot or threaded screw to an elongate spring-type member, anchoring head features for stabilizing position of the elongate member when engaged within the head and/or digital or electronic methods for tensioning the subject devices.

## Claims

### Claim 1

A medical device comprising:
an elongate spring member with a longitudinal axis therebetween, the spring member including a plurality of cells including deflectable lateral beams connected at an outer extent, each of the plurality of cells connected to an adjacent cell of the plurality of cells at a medial connector, a disposable introducer integrally connected to the elongate spring member in a final implant confirmation.

### Claim 2 (depends on 1)

The medical device of claim 1, wherein at least one of the two anchoring members has at least one strand of material passing therethrough.

### Claim 3 (depends on 2)

The medical device of claim 2, wherein the at least one strand of material passes through each of the two anchoring members via through-holes.

### Claim 4 (depends on 1)

The medical device of claim 1, wherein the anchoring members are anchoring heads.

### Claim 5 (depends on 1)

The medical device of claim 1, wherein the introducer is an introduction needle.

### Claim 6 (depends on 5)

The medical device of claim 5, comprising a reduced-width bridge section between the spring member and the introduction needle.

### Claim 7 (depends on 6)

The medical device of claim 6, further comprising a tab including an eyelet adjacent the elongate spring member, wherein the introduction needle is attached to the elongate spring member with at least one strand of suture passed through the eyelet.

### Claim 8 (depends on 1)

The medical device of claim 1, where in the end feature is the screw head.

### Claim 9 (depends on 8)

The medical device of claim 8, comprising a tab adjacent the spring member, wherein the tab is received in a slot of the screw head.

### Claim 10 (depends on 9)

The medical device of claim 9, wherein the tab includes an eyelet and a pin received by the screw head to the tab.

### Claim 11 (depends on 10)

The medical device of claim 10, wherein a proximal portion of the secondary section extends at least 1 mm proximal to a face of the screw head to provide a driver interface.

### Claim 12 (depends on 1)

The medical device of claim 1, wherein the end feature is the longitudinal extension, anchoring foot, and the pin.

### Claim 13 (depends on 12)

The medical device of claim 12, wherein the longitudinal extension is twisted 90 degrees so that the anchoring foot aligns with a face of the elongate spring member when the anchoring foot is pivoted for deployment.

### Claim 14 (depends on 12)

The medical device of claim 12, wherein the longitudinal extension is inset from an outer extent of the beams and has a length to fit at least part of the ends of the anchoring foot inward of the outer extent when the anchoring foot is pivoted to align with the longitudinal extension.

### Claim 15 (depends on 12)

The medical device of claim 12, wherein the anchoring foot is pinned through a pair of bosses extending from a proximal surface of the foot.

### Claim 16 (depends on 15)

The medical device of claim 15, wherein each boss is capped with a full radius.

### Claim 17 (depends on 15)

The medical device of claim 15, wherein each boss is capped by an inwardly-angled or curved fin.

### Claim 18 (depends on 1)

The medical device of claim 1, further comprising an anchoring head engaging the deflectable lateral beams.

### Claim 19 (depends on 1)

The medical device of claim 1, wherein the two anchoring members are two anchoring heads engaging the deflectable lateral beams at a proximal end and at a distal end of the elongate spring member.

### Claim 20 (depends on 1)

The medical device of claim 1, wherein at least the spring member comprises NiTi alloy that is superelastic at human body temperature.

### Claim 21 (depends on 4)

The medical device of claim 4, wherein the anchoring members are two anchoring heads facing in opposite directions along the elongate spring member.

### Claim 22 (depends on 4)

The medical device of claim 4, wherein the anchoring members are two anchoring heads arrayed in a mirror image pattern along the elongate spring member.
