Abstract
A medical device that includes a shaft having a distal end and a cap at the distal end that defines a reservoir for storing a material. The medical device includes a deployment mechanism configured to eject the material from the reservoir, and the deployment mechanism is configured to apply a force to the reservoir. The cap includes a seal or a perforation that is configured to contain the material in the reservoir in the absence of the force applied by the deployment mechanism to the material.
Claims20
A medical device, comprising:
- a shaft having a distal end, wherein the distal end includes an opening and an imaging device;
- a cap at the distal end of the shaft, wherein the cap defines a first reservoir for storing a material and a second reservoir, wherein the second reservoir is aligned with the imaging device such that the imaging device is able to capture images distally of the cap through a distal face of the cap, and wherein the first reservoir is misaligned from the imaging device, such that the imaging device is isolated from the material stored in the first reservoir;
- and
- a deployment mechanism configured to eject the material from the first reservoir, wherein the deployment mechanism includes a movable floor that is distal of the distal end of the shaft, wherein the movable floor is configured to apply a force to the material in the first reservoir, wherein the movable floor includes a protrusion that is received within the opening of the distal end of the shaft;
- wherein the cap includes a seal, wherein the seal is configured to contain the material in the first reservoir in an absence of the force applied by the deployment mechanism to the material.
2 more elements
A medical device, comprising:
- a cap configured to be attached to a distal end of a scope, wherein the cap defines a first reservoir for storing a material, and a second reservoir, wherein the second reservoir is isolated from the first reservoir by a wall, wherein the wall extends from a proximalmost end of the cap to a distalmost end of the cap, wherein the cap includes:
- a removable seal configured to expose the first reservoir and the material upon removal of the seal from a remainder of the cap;
- and
- a deployment mechanism configured to eject the material from the first reservoir, wherein the deployment mechanism includes:
- a movable floor, wherein the movable floor is distal of the distal end of the scope, wherein the movable floor is configured to generate a positive pressure within the first reservoir as the movable floor moves distally within the first reservoir;
- and
- a protrusion, wherein the protrusion is received within an opening of the distal end of the scope.
4 more elements
A medical device, comprising:
- a cap configured for attachment to a distal end of a shaft of a scope, wherein the cap defines a first reservoir for storing a material and a second reservoir, wherein the second reservoir is isolated from the first reservoir by a wall and extends from a proximalmost end of the cap to a distalmost end of the cap, wherein the cap includes a deployment mechanism configured to eject the material from the first reservoir, wherein the deployment mechanism includes:
- a movable floor that is distal to the distal end of the scope, wherein the movable floor is configured to apply a force to the material in the first reservoir, wherein the movable floor includes a protrusion on a proximal surface of the movable floor, wherein the protrusion is received within an opening of the distal end of the scope, and wherein the movable floor is isolated from the second reservoir;
- and
- a movable rod, wherein the movable rod is disposed within a lumen of the shaft and extendable from the distal end of the scope, wherein the protrusion of the movable floor is configured to align the movable rod with the movable floor.
