Abstract
Disclosed herein are methods and medical devices for controlled delivery of material compositions, such as occlusive, therapeutic, or diagnostic compositions. A method disclosed herein comprises providing an occlusive composition to a human or animal. Other methods may include providing compositions for treatment, diagnosis or other conditions using disclosed medical devices.
Claims16
A method for occluding at least one fallopian tube in a human or animal body, comprising,
- a) measuring the depth of the uterus of the human or animal using a uterine sound or measuring the uterine depth using sonography;
- b) providing to the uterus of a human or animal a controlled delivery device capable of delivering an effective amount of a composition comprising an occlusive material, wherein the delivery device comprises at least an insertion tube for providing at least one catheter;
- at least one catheter comprising an end structure on a delivery end that maintains the delivery end in at least one uterine cornua and aids in localized delivery of the composition;
- a handle comprising a level, a receptacle for receiving a material cartridge and a slider for moving a catheter slide, wherein the catheter slide moves the at least one catheter in a proximal or distal direction;
- a system plunger controlled by a lock, wherein the lock is movable between position one and position two;
- wherein the system plunger is reversibly coupled to a control rod, the control rod defining two sets of parallel connecting elements, one set comprising attachment elements for moving two air syringes, and a second set comprising positioning elements, for moving material plunger actuators;
- wherein the lock is movable between a first position and a second position, and, when the lock is in the first position, the system plunger and the control rod are coupled such that movement of the system plunger moves the control rod, and when the lock is in the second position, the system plunger and the control rod are uncoupled such that the system plunger can move independently of the control rod and a material cartridge containing the composition comprising an occlusive material positioned within the receptacle in the handle;
- c) delivering an effective amount of the composition comprising an occlusive material through and out the at least one catheter at or near the uterine cornua such that the occlusive material occludes the lumen of the fallopian comprising the following steps:
- i) with the system plunger rigidly coupled with the control rod and the lock in the lock position one, inserting the material cartridge containing the occlusive material within the receptacle in the handle;
- ii) moving the slider from a proximal position to a distal position so that the catheter slide moves the at least one catheter so that the at least one catheter delivery end exits the insertion tube and is positioned in the uterine cornua;
- iii) distally moving the rigidly coupled system plunger and control rod so that air is moved to fill the end structure of at least one catheter;
- iv) moving the lock to the lock position two which uncouples the system plunger from the control rod so that when system plunger moves, the control rod is stationary;
- v) moving the system plunger further distally, while the control rod remains stationary, so that the occlusive material is moved from the material cartridge through and out the delivery end of at least one catheter and into at least the uterine cornua;
- vi) returning the lock to the lock position one to rigidly reengage the system plunger and the control rod;
- vii) moving the rigidly engaged system plunger and control rod in a proximal direction which deflates the end structure of at least one catheter;
- and
- viii) withdrawing the insertion tube from the human or animal body.

A method for contraception in a human or animal body, comprising,
- a) measuring the depth of the uterus of the human or animal using a uterine sound or measuring the uterine depth using sonography;
- b) providing to the uterus of a human or animal a controlled delivery device capable of delivering an effective amount of a composition comprising an occlusive material, wherein the delivery device comprises at least an insertion tube for providing at least one catheter;
- at least one catheter comprising an end structure on a delivery end that maintains the delivery end in at least one uterine cornua and aids in localized delivery of the composition;
- a handle comprising a level, a receptacle for receiving a material cartridge and a slider for moving a catheter slide, wherein the catheter slide moves the at least one catheter in a proximal or distal direction;
- a system plunger controlled by a lock, wherein the lock is movable between position one and position two;
- wherein the system plunger is reversibly coupled to a control rod, the control rod defining two sets of parallel connecting elements, one set comprising attachment elements for moving two air syringes, and a second set comprising positioning elements, for moving material plunger actuators;
- wherein the lock is movable between a first position and a second position, and, when the lock is in the first position, the system plunger and the control rod are coupled such that movement of the system plunger moves the control rod, and when the lock is in the second position, the system plunger and the control rod are uncoupled such that the system plunger can move independently of the control rod and a material cartridge containing the composition comprising an occlusive material positioned within the receptacle in the handle;
- c) delivering an effective amount of the composition comprising an occlusive material through and out the at least one catheter at or near the uterine cornua such that the occlusive material occludes the lumen of the fallopian comprising the following steps:
- i) with the system plunger rigidly coupled with the control rod and the lock in the lock position one, inserting the material cartridge containing the occlusive material within the receptacle in the handle;
- ii) moving the slider from a proximal position to a distal position so that the catheter slide moves the at least one catheter so that the at least one catheter delivery end exits the insertion tube and is positioned in the uterine cornua;
- iii) distally moving the rigidly coupled system plunger and control rod so that air is moved to fill the end structure of at least one catheter;
- iv) moving the lock to the lock position two which uncouples the system plunger from the control rod so that when system plunger moves, the control rod is stationary;
- v) moving the system plunger further distally, while the control rod remains stationary, so that the occlusive material is moved from the material cartridge through and out the delivery end of at least one catheter and into at least the uterine cornua;
- vi) returning the lock to the lock position one to rigidly reengage the system plunger and the control rod;
- vii) moving the rigidly engaged system plunger and control rod in a proximal direction which deflates the end structure of at least one catheter;
- and
- viii) withdrawing the insertion tube from the human or animal body.
