Introducer devices and methods of use thereof

An implant introducer comprising:

• a nozzle having a nozzle body extending around a cavity, the nozzle body extending from a proximal portion to a distal portion;
• wherein the proximal portion includes a nozzle engagement surface;
• a nozzle receiver including:
• a distal nozzle receiver portion coupled to the proximal portion of the nozzle body;
• and
• a distally facing inner surface;
• an expandable membrane coupled to the distally facing inner surface of the nozzle receiver, the expandable membrane configured to expand distally within the cavity;
• a fluid supply conduit extending from a distal portion of the nozzle receiver and fluidly coupled with the expandable membrane;
• and
• a user-controlled, inflation device coupled with a proximal portion of the fluid supply conduit, the user-controlled, inflation device configured supply a fluid through the fluid supply conduit to the expandable membrane.

An implant introducer comprising:

• a nozzle having a nozzle body surrounding a cavity, the nozzle body extending from a proximal portion to a distal portion, a nozzle engagement surface located along the proximal portion;
• wherein the proximal portion includes a proximal opening wider than a distal opening of the distal portion;
• a nozzle receiver including an inner surface configured to close the proximal portion of the nozzle body, and a nozzle receiver engagement surface, the nozzle receiver engagement surface couplable with the nozzle engagement surface;
• an expandable membrane coupled with the inner surface of the nozzle receiver;
• wherein the expandable membrane is configured to expand distally into the cavity;
• a fluid supply conduit including a distal portion in fluid communication with the nozzle receiver;
• and
• a user-controlled inflation device coupled with a proximal portion of the fluid supply conduit;
• wherein the fluid supply conduit fluidly couples the user-controlled inflation device with the expandable membrane;
• wherein the user-controlled inflation device is manually engaged to supply a pressurized fluid through the fluid supply conduit to the expandable membrane.
