Abstract
The present invention comprises systems, methods and devices for the delivery of compositions for occluding or of elements for opening conduits. The implantable occlusive material may be delivered pre-formed or in situ cured and, may be a resorbable or degradable material that supports tissue ingrowth or wound healing or a similar response that replaces the cured occlusive material leaving little or no original occlusive material in place. The delivery system is positioned to allow for placement of the occlusive material into the body conduit. Use of delivery systems, methods and devices for re-opening an occluded body conduit are also included.
Claims23
A method for occluding at least one conduit in a human or animal body, comprising,
- a) providing a delivery system capable of delivering an effective amount of a composition comprising an occlusive material, wherein the delivery system comprises a delivery device comprising at least an introducer shaft with at least one exit port for providing at least one catheter;
- at least one catheter, a composition comprising an occlusive material, and elements for providing the composition comprising an occlusive material into and through at least one catheter;
- b) delivering an effective amount of the composition comprising an occlusive material at or near the target site;
- and
- c) occluding the conduit by forming an occlusion with the cured composition comprising an occlusive material within the lumen of the conduit.
A method for contraception, comprising,
- a) providing a delivery system capable of delivering an effective amount of a composition comprising an occlusive material, wherein the delivery system comprises a delivery device comprising at least an introducer shaft with at least one exit port for providing at least one catheter;
- at least one catheter, a composition comprising an occlusive material, and elements for providing the composition comprising an occlusive material into and through at least one catheter;
- b) delivering an effective amount of the composition comprising an occlusive material at or near the target location such that the material is provided to a portion of a lumen of at least one fallopian tube;
- and
- c) occluding the fallopian tube by forming an occlusion with the cured composition comprising an occlusive material within the lumen of the conduit.
A transcervical device, comprising, an introducer shaft with at least one exit port for providing at least one catheter;
- at least one catheter comprising an end structure on a delivery end and attachment elements on a proximal end, and elements for providing a composition into and through at least one catheter.
A method for opening the lumen of at least one occluded fallopian tube comprising
- a) providing a delivery system comprising a delivery device comprising at least an introducer shaft with at least one exit port for providing at least one catheter;
- at least one catheter comprising an end structure on a delivery end, and one or more elements for opening a conduit,
- b) providing the introducer shaft through the cervix,
- c) advancing the delivery end of at least one catheter through the introducer shaft and out at least one exit port;
- d) positioning the delivery end of the catheter at the cornua of the uterus so that the elements for opening a conduit are at an occlusion in the lumen of the fallopian tube;
- e) activating the one or more elements for opening a conduit to effect an occlusion of the lumen of a fallopian tube;
- and
- f) opening the lumen of a fallopian tube.
