## Abstract

An insertion apparatus for inserting an object into a body comprising a housing, a piercing structure with a lumen, wherein the piercing structure extends distally from the housing, a vacuum chamber that communicates with the lumen of the piercing structure, a plunger configured to fit within the vacuum chamber, and a guidewire, wherein the insertion apparatus is configured to be operated with a single hand.

## Claims

### Claim 1

An insertion apparatus for inserting an object into a body, comprising:
an elongated housing having a distal end and a proximal end, at least one fixed handle extending from the proximal end of the housing, and a guidewire sheath clip disposed on an upper surface of the housing adjacent the proximal end;
a piercing structure with a lumen disposed adjacent the upper surface of the housing, wherein the piercing structure extends from the distal end of the housing;
a vacuum chamber disposed with in the housing and that communicates with the lumen of the piercing structure;
a plunger configured to fit within the vacuum chamber and having a handle external to the chamber and disposed adjacent the distal end of the housing when the plunger is fully disposed in the chamber; and
a guidewire extending from the guidewire sheath clip into the lumen;
a protuberance disposed on the housing between the guidewire clip and the piercing structure arranged so that a digit of a use can sandwich the guidewire between the digit and the protuberance;
wherein the insertion apparatus is configured to be gripped with a single hand and the plunger retracted from the fully disposed condition with another digit of the single hand.

### Claim 2 (depends on 1)

The insertion apparatus of claim 1, wherein the piercing structure is a needle.

### Claim 3 (depends on 1)

The insertion apparatus of claim 1, wherein the vacuum chamber is integrated with the housing.

### Claim 4 (depends on 1)

The insertion apparatus of claim 1, wherein the housing further comprises a first conduit through which the vacuum chamber communicates with the lumen of the piercing structure.

### Claim 5 (depends on 4)

The insertion apparatus of claim 4, wherein the housing further comprises a second conduit configured to receive the guidewire such that the guidewire can communicate with the lumen of the piercing structure.

### Claim 6 (depends on 5)

The insertion apparatus of claim 5, further comprising a valve, wherein the valve is configured in the second conduit and configured to restrict the flow of air through the second conduit.

### Claim 7 (depends on 1)

The insertion apparatus of claim 1, wherein the valve is configured to provide a seal around the guidewire, wherein the seal permits passage of the guidewire through the second conduit and into the lumen of the piercing structure while restrict the flow of air through the second conduit.
