Medical delivery devices, assemblies, and related methods

An assembly of a medical delivery device, comprising:

• an inner sleeve including a flange at a proximal end, the flange including one or more through holes;
• an outer sleeve movably coupled to the inner sleeve, a distal tip of the outer sleeve including a plurality of openings for delivering an adhesive to a treatment site;
• a cavity formed between the inner sleeve and the outer sleeve and configured to hold the adhesive prior to the delivering;
• a gasket positioned at a distal contact point of the inner sleeve and the outer sleeve that extends to the distal tip of the outer sleeve and includes a plurality of flaps corresponding to and covering the plurality of openings at the distal tip;
• and
• one or more actuators connected to a proximal end of the outer sleeve and extended via the one or more through holes to a handle of the medical delivery device, wherein actuation of the one or more actuators moves one of the inner sleeve or the outer sleeve relative to the other to pressurize the adhesive in the cavity causing the plurality of flaps to be forced open and the adhesive to be delivered via the plurality of openings.

A medical delivery device, comprising:

• a handle including one or more actuation mechanisms;
• and
• one or more assemblies mountable to a medical device, each of the one or more assemblies including:
• an inner sleeve including a flange at a proximal end, the flange including one or more through holes;
• an outer sleeve movably coupled to the inner sleeve, a distal tip of the outer sleeve including a plurality of openings for delivering adhesive to a treatment site;
• a cavity formed between the inner sleeve and the outer sleeve and configured to hold the adhesive prior to the delivering;
• and
• one or more actuators connected to a proximal end of the outer sleeve and extended via the one or more through holes to the handle of the medical delivery device, wherein actuation of the one or more actuators via the one or more actuation mechanisms moves one of the inner sleeve or the outer sleeve relative to the other to cause the delivering of the adhesive.
