## Abstract

An inflatable compression device configured to apply a compressive force to a puncture site of a patient's vessel, such as an artery is disclosed. The hemostasis device may comprise a location indicium disposed on an inside surface of an inflatable bladder portion of the device so as to be disposed in close proximity to the skin of the patient to improve alignment of the compression device with the puncture site.

## Claims

### Claim 1

An inflatable hemostasis device, comprising:
a top plate; and
a bladder sealably coupled to the top plate along a perimeter of the bladder,
wherein the bladder comprises a location indicium.

### Claim 2 (depends on 1)

The inflatable hemostasis device of claim 1, further comprising an inflatable hemostasis device securement system coupled to the top plate, wherein the securement system is configured to secure the bladder over a puncture site.

### Claim 3 (depends on 1)

The inflatable hemostasis device of claim 1, wherein the bladder and top plate are transparent.

### Claim 4 (depends on 1)

The inflatable hemostasis device of claim 1, wherein a projected indicium location on a patient viewed from an angle of 45 degrees away from a normal axis to the top plate is less than 3 mm away from a projected indicium location on the patient when viewed along the normal axis.

### Claim 5 (depends on 1)

The inflatable hemostasis device of claim 1, wherein the location indicium is disposed on a bladder surface.

### Claim 6 (depends on 1)

The inflatable hemostasis device of claim 1, wherein the location indicium is disposed adjacent a central location of the bladder.

### Claim 7 (depends on 1)

The inflatable hemostasis device of claim 1, wherein the location indicium is disposed adjacent an apex of the bladder when inflated.

### Claim 8 (depends on 1)

The inflatable hemostasis device of claim 1, wherein the location indicium is located on an inner surface of the bladder.

### Claim 9 (depends on 1)

The inflatable hemostasis device of claim 1, wherein the location indicium comprises a visibly altered portion of a bladder surface.

### Claim 10 (depends on 1)

The inflatable hemostasis device of claim 1, wherein the top plate is rigid.

### Claim 11

A method of applying a compressive force to a puncture site, comprising:
obtaining an inflatable hemostasis device comprising:
a transparent fluid bladder, wherein the bladder comprises a location indicium disposed thereon; and
aligning the location indicium with the puncture site.

### Claim 12 (depends on 11)

The method of claim 11, further comprising moving the location indicium closer to the skin of the patient by at least partially inflating the bladder.

### Claim 13 (depends on 11)

The method of claim 11, further comprising adjusting the alignment of the location indicium with the puncture site based on visual observation of insufficient alignment of the location indicium relative to the puncture site.

### Claim 14 (depends on 11)

The method of claim 11, further comprising securing the inflatable hemostasis device to a patient.

### Claim 15 (depends on 11)

The method of claim 11, further comprising adjusting a fluid volume in the bladder prior to securing the device to a patient.

### Claim 16

A method of assembling an inflatable hemostasis device comprising:
obtaining a top plate and a bladder;
marking the bladder with a location indicium; and
sealably coupling the bladder to a bottom surface of the top plate.

### Claim 17 (depends on 16)

The method of claim 16, wherein marking the bladder comprises visibly altering a portion of a bladder surface.

### Claim 18 (depends on 16)

The method of claim 16, wherein marking the bladder comprises at least one of laser marking, attaching a label, chemical etching, heat staking, forming depressions or protrusions, and printing.

### Claim 19 (depends on 16)

The method of claim 16, wherein marking the bladder comprises disposing a visible substance on an inner surface of the bladder.

### Claim 20 (depends on 16)

The method of claim 16, further comprising preparing the inner surface for marking comprising at least one of wiping the surface with a degreasing agent, applying a primer, altering the surface finish and removing static charge.
