Abstract
A medical system includes a medical device having a handle, a shaft, an actuation member, and medical system also includes a cartridge and a plunger. The handle includes an actuator movable relative to the handle, and the actuator is coupled to a distal end of the shaft via the actuation member. The cartridge contains a treatment agent, and the cartridge is couplable to the distal end of the shaft. The plunger is movable relative to the cartridge. Movement of the actuator controls movement of the actuation member. Movement of the actuation member controls movement of either the plunger or the cartridge to control a delivery of the treatment agent from the cartridge.
Claims20
A medical system, comprising:
- a medical device having a handle, a shaft, and an actuation member including a plurality of wires, wherein the handle includes an actuator movable relative to the handle, and wherein the actuator is coupled to a distal end of the shaft via the actuation member;
- a cartridge containing a treatment agent, wherein the cartridge is couplable to the distal end of the shaft;
- and
- a plunger that is movable relative to the cartridge,
- wherein the distal end of the shaft includes a plurality of fulcrum portions fixed within the distal end of the shaft,
- wherein each of the plurality of wires is paired with one of the plurality of fulcrum portions, and
- wherein each of the plurality of wires extends from the actuator distally beyond each of the plurality of fulcrum portions to a portion of the plunger proximate to the plurality of fulcrum portions, such that proximal movement of the actuator urges the plurality of wires proximally and also urges the plunger distally to deliver the treatment agent from the cartridge.
A medical device, comprising:
- an actuation member;
- a cartridge containing a treatment agent, wherein the cartridge includes a proximal extension with a peg, and wherein the cartridge is removably couplable to a distal end of a shaft via the proximal extension;
- and
- a plunger that is movable relative to the cartridge,
- wherein the distal end of the shaft includes a plurality of fixation portions extending radially inwards within the shaft,
- wherein a first portion of the actuation member extends around a first fixation portion of the plurality of fixation portions to a first portion of the plunger proximate to the first fixation portion,
- wherein a second portion of the actuation member extends around a second fixation portion of the plurality of fixation portions to a second portion of the plunger proximate to the second fixation portion, and
- wherein proximal movement of the actuation member urges the first portion of the actuation member and the second portion of the actuation member proximally and also urges the plunger distally to deliver the treatment agent from the cartridge.
A method, comprising:
- delivering a distal end of a medical device to a treatment site;
- manipulating an actuator on a proximal handle to deliver an agent from a cartridge to the treatment site, wherein the actuator actuates a plurality of actuation members, wherein each of the plurality of actuation members is paired with a portion of a fulcrum element,
- wherein proximal movement of the actuator urges a plunger distally to deliver the agent from the cartridge;
- and
- removing the medical device and the cartridge from the treatment site.
