Abstract

The invention provides an insertion device for insertion of conduits into a body that, before and following deployment of the conduit into the body, has no components that require insertion into or removal from the device. Additionally, the device includes a component that not only prevents re-use or reopening of the device once it is activated, but also provides feedback to the user in the form of a resistance force to activation that must be overcome by the user to deploy the conduit.

Claims

1. An insertion device for inserting a conduit into a body, the device comprising:

a base plate;

a lower housing disposed on a first surface of the base plate, the lower housing comprising a latch, at least one guide support, and a first channel through the lower housing;

a guide for supporting at least a portion of a conduit while the device is in an unactivated state, wherein the guide is movably engageable with the lower housing;

a clamp movably attached to a first end of the lower housing, the clamp comprising at least one first component that releasably engages with the lower housing latch and a second component that non-releasably engages with the lower housing latch

an upper housing seated on the clamp and movably engaged with the guide;

a second channel in communication with the first channel; and

a conduit within the first and second channels.

2. The insertion device of claim 1, wherein the at least one first component comprises at least one actuator extending from a first surface of the clamp and the at least one second component comprises at least one strike extending from a second surface of the clamp.

3. The insertion device of claim 2, wherein the clamp strike is located substantially opposite the clamp actuator.

4. The device of claim 1, wherein the second channel is formed between the clamp and the upper housing.

5. The device of claim 1, comprising at least one additional lock.

6. The insertion device of claim 5, wherein the at least one additional lock comprises at least one latch tab for frictionally engaging an inner surface of the lower housing on a front surface of the upper housing and at least one tab slot on the inner surface of the lower housing for non-releasable engagement of the at least one latch tab.

7. The insertion device of claim 6, wherein the lower housing inner surface further comprises at least one flexible tab member for frictional engagement with the at least one latch tab.

8. The insertion device of claim 7, wherein the lower housing inner surface further comprises at least one slotted relief.

10. The insertion device of claims 1, 2, and 5, wherein the conduit is a flexible medical conduit.

9. The insertion 7, wherein the lower housing inner surface further comprises slotted reliefs on either side of the at least one flexible tab member.
