Medical devices for delivering plugs to voids

1. A method of delivering a medical plug into a patient comprising:

obtaining a medical plug delivery system comprising a medical plug delivery device and a medical plug;

connecting the medical plug delivery device to a medical appliance in communication with a patient;

selecting a technique of medical plug delivery from at least one of the following:

(i) connecting a fluid delivery device to the medical plug delivery device and displacing fluid with sufficient force to displace the medical plug; and

(ii) inserting a stylet into a proximal end of the medical plug delivery device with sufficient force to displace the medical plug; and

displacing the medical plug from the medical plug delivery device according to the selected technique;

wherein the medical plug delivery device comprises a housing defining a cavity, wherein the housing comprises a distal connector configured to connect to the medical appliance in communication with the patient; and

a plug cartridge defining a cavity configured to receive the medical plug, wherein the plug cartridge is disposed within the cavity of the housing, the plug cartridge comprising apertures in communication with the cavity of the housing;

wherein the housing further defines a shoulder at a proximal end of the cavity, the shoulder being configured to engage the medical plug and prevent the medical plug's movement proximal of the shoulder;

wherein the cavity of the plug cartridge is structured to frictionally engage the medical plug within the cavity of the plug cartridge until:

(i) a distally directed flow of fluid passes through the cavity of the plug cartridge with sufficient force to overcome the engaging; or

(ii) a distally directed force from the stylet is applied to the medical plug sufficient to displace the medical plug.

2. The method of claim 1 , wherein the medical plug is displaced into the medical appliance in communication with the patient.

3. The method of claim 2 , further comprising inserting a trocar into the medical appliance in communication with the patient wherein the trocar is configured to displace the medical plug into the patient.

4. The method of claim 1 , wherein the medical plug is displaced into the patient.

5. A method of injecting a medical plug into a patient, comprising:

obtaining a medical plug delivery device with an medical plug;

wherein the medical plug delivery device comprises a housing defining a cavity which maintains the longitudinal axes of the medical plug and the medical plug delivery device in alignment, wherein the housing comprises a distal connector configured to connect to an introducer; and

a plug cartridge defining a cavity configured to receive the medical plug, wherein the plug cartridge is disposed within the cavity of the housing, the plug cartridge comprising apertures in fluid communication with the cavity of the housing;

wherein the housing further defines a shoulder at a proximal end of the cavity, the shoulder being configured to engage the medical plug and prevent the medical plug's movement proximal of the shoulder;

wherein the cavity of the plug cartridge is structured to frictionally engage the medical plug within the cavity of the plug cartridge until a distally directed flow of fluid passes through the cavity of the plug cartridge with sufficient force to overcome the engaging;

connecting a proximal end of the medical plug delivery device to a fluid delivery device;

connecting a distal end of the medical plug delivery device to the introducer;

delivering fluid from the fluid delivery device into the cavity of the plug cartridge medical plug delivery device;

deploying the medical plug from the cavity of the plug cartridge medical plug delivery device into the introducer via the fluid delivered from the fluid delivery device; and

introducing the medical plug to a patient via the introducer.

6. The method of claim 5 , further comprising delivering fluid from the fluid delivery device such that the fluid is delivered around the medical plug to remove air bubbles prior to connecting the distal end of the medical plug delivery device to the introducer.

7. The method of claim 5 , further comprising wetting of the medical plug, wherein wetting of the medical plug causes expansion of the medical plug.

8. A method of delivering a medical plug to a patient, the method comprising:

obtaining a medical plug delivery device comprising a channel, wherein a cross-section of the medical plug delivery device that is perpendicular to a longitudinal axis of the medical plug delivery device defines a perimeter of a portion of the channel, wherein the perimeter comprises:

a plurality of inward-most points at a first radius from a longitudinal axis of the perimeter; and

a plurality of outward-most points at a second radius from the longitudinal axis of the perimeter, wherein the second radius is longer than the first radius;

wherein a dry medical plug is disposed within the channel;

connecting a proximal end of the medical plug delivery device to a fluid delivery device;

connecting a distal end of the medical plug delivery device to an introducer; and

deploying the medical plug from the channel of the medical plug delivery device such that the medical plug passes through the introducer and into the patient;

wherein the medical plug delivery device comprises:

a housing defining the channel that extends from the proximal end of the medical plug delivery device to the distal end of the medical plug delivery device, wherein the portion of the channel is configured to receive the medical plug;

a distal connector configured to a connect to the introducer;

a proximal connector configured to connect to the fluid delivery device;

wherein each inward-most point of the plurality of inward-most points is disposed on an apex of a convex curve,

wherein each outward-most point of the plurality of outward most points is disposed on an apex of a concave curve,

wherein the plurality of inward-most points and the plurality of outward-most points are spaced radially apart along the perimeter, and

wherein the plurality of inward-most points and the plurality of outward-most points extend continuously along a longitudinal length of the channel.

9. The method of claim 8 , further comprising delivering fluid from the fluid delivery device such that the fluid is delivered around the medical plug to remove air bubbles prior to connecting the distal end of the medical plug delivery device to the introducer.

10. The method of claim 8 , further comprising wetting of the medical plug, wherein wetting of the medical plug causes expansion of the medical plug.
