Device for delivery of a foamable composition
First Claim
1. A device for delivery of a foamable composition to a body cavity, the device comprising:
- a pressurizable composition reservoir capable of receiving a foamable composition;
a hollow body having distal and proximal ends and a plurality of apertures comprising at least first and second apertures provided through a side wall of said hollow body, the proximal end in fluid communication with the reservoir via an actuator, said hollow body being shaped and adapted for insertion within a body cavity; and
an actuator including a valve operatively connected to the composition reservoir for effecting release of the foamable composition from said composition reservoir into a body cavity through said actuator and hollow body,wherein said hollow body has a length less than about 125 mm;
wherein the plurality of apertures of the hollow body are located at distances from said proximal end that are within the range from about 90% to about 25% of the length of said hollow body and said hollow body lacks an aperture at its distal end;
wherein said first aperture is located closer to the distal end, and said second aperture is located closer to the proximal end, andwherein the aperture size of said first aperture is larger than the aperture size of said second aperture.

Abstract
A device for delivery of a foamable composition to a body cavity includes a pressurized composition reservoir; a hollow body having a longitudinally extending wall and having at least one aperture provided through a wall of said body, the proximal end in fluid communication with the reservoir for receiving a foamable composition from said composition reservoir; and an actuator operatively connected to the composition reservoir for effecting release of a foamable composition from said composition reservoir into a body cavity through said hollow body; wherein said body has a length less than about 125 mm and internal diameter in the range of about 1.5 mm to about 3.5 mm, wherein said length and internal diameter are selected to provide a delivery of at least about 70% of the foamable composition during operation. The foam delivery device can have multiple apertures.

55. A device comprising:
-
a pressurized canister containing a foamable composition; a catheter having a first and second catheter end; wherein the catheter is sufficiently flexible to conform to the contours of a body cavity into which it is inserted and is suitable for delivering the foamable composition into a deep body cavity and deliver the foam to a target area within the deep body cavity; a connector that connects the canister to the catheter at the first catheter end which, when connected, provides a first pressure sensitive seal so that foam released from the canister passes into and through the catheter without escaping through the first pressure-sensitive seal; the second catheter end suitable for discharging foam or for receiving a foam applicator; wherein the foam applicator is adapted to discharge foam into a body cavity and when connected to the second catheter end provides a second pressure sensitive seal so that foam does not escape from the second pressure-sensitive seal; and wherein the pressurized canister comprises an actuator including a valve and port and the connector connects with the canister at the port to provide the first pressure sensitive seal. - View Dependent Claims (56)

57. A device for delivery of a foamable composition to a body cavity, the device comprising:
-
a hollow body having distal and proximal ends, an inner diameter, and a plurality of apertures comprising at least first and second apertures provided through a side wall of said hollow body, the proximal end adapted to be in fluid communication with a reservoir via an actuator for receiving a foamable composition, said hollow body being shaped and adapted for insertion within a body cavity; and an actuator including a valve and port operatively connected to the hollow body for effecting release of a foamable composition from said hollow body; wherein the plurality of apertures of the hollow body are located at distances from said proximal end that are within the range from about 90% to about 25% of the length of said hollow body and said hollow body lacks an aperture at its distal end; wherein said first aperture is located closer to the distal, and said second aperture is located closer to the proximal end; wherein the aperture size of said first aperture is larger than the aperture size of said second aperture; and wherein the location and relative size of said first and second apertures are selected to provide delivery of the foam in a preselected proportion from each aperture so as to provide the maximal coverage of a body coverage with the minimal amount of foamable composition.
