Deployable constrictor for uterine artery occlusion
First Claim
1. A uterine artery occlusion device, comprising:
- a deployable constrictor having an interior configured to receive a female patient'"'"'s uterine cervix and having at least one pressure-applying portion having a pressure-applying surface configured to apply pressure to the patient'"'"'s uterine cervix or a vaginal surface to thereby occlude at least one of the patient'"'"'s uterine arteries;
an elongated delivery shaft configured to intravaginally advance said constrictor to the patient'"'"'s uterine cervix;
a deployment member configured to deploy said constrictor from said delivery shaft about the patient'"'"'s uterine cervix so that pressure applied by constriction of the pressure applying surface of the constrictor occludes at least one of the patient'"'"'s uterine arteries; and
at least one locating sensor provided on a distal portion of the device configured to detect a blood vessel.

Abstract
Devices, systems and methods for occluding blood vessels include a deployable constrictor having opposed pressure-applying portions, a delivery shaft configured to intravaginally advance the constrictor to the patient'"'"'s cervix, a location sensor configured to detect a blood vessel, a deployment member for deploying the constrictor about the patient'"'"'s cervix, and optionally a guide. The constrictor has a first configuration to receive a cervix and a second configuration to apply pressure to the cervical area to occlude a uterine artery by compression from the pressure-applying members. The pressure-applying members may be released from the cervix after a limited therapeutically effective time. The constrictor is for treating uterine disorders and conditions which may be treated by occlusion of the uterine arteries, such as uterine fibroids, dysfunctional uterine bleeding, post-partum hemorrhage, and bleeding associated with caesarian sections.

23. A system for occluding a blood vessel for use by an operator, comprising:
a blood vessel occlusion device, comprising; a deployable constrictor having at least one pair of opposed pressure-applying members having a first configuration to receive a female patient'"'"'s cervix and a second configuration to apply pressure to the patient'"'"'s cervix or uterus to occlude at least one of the patient'"'"'s uterine arteries; a delivery shaft configured to intravaginally advance said deployable constrictor in a first configuration to receive at least in the patient'"'"'s cervix, said delivery shaft having a longitudinal axis defining a longitudinal direction; a deployment member configured to deploy the deployable constrictor from the delivery shaft effective that said deployable constrictor assumes a second configuration about at least part of the patient'"'"'s cervix and to thereby at least partially occlude a uterine artery; a sensor configured to detect a blood vessel and disposed on at least one of said delivery shaft and said deployable constrictor; and a sensor controller operatively connected to said sensor and comprising a source of power. - View Dependent Claims (24, 25, 26, 27)

28. A system for occluding a a female patient'"'"'s uterine artery, comprising:
an occlusion device, comprising; a deployable constrictor having at least one pair of opposed pressure-applying members which have a first configuration to receive a female patient'"'"'s cervix and a second configuration to apply pressure to the patient'"'"'s cervix or vaginal surface to occlude at least one of the patient'"'"'s uterine arteries; a delivery shaft configured to intravaginally advance said deployable constrictor in the first configuration to receive at least in the patient'"'"'s cervix, said delivery shaft having a longitudinal axis defining a longitudinal direction; a deployment member configured to deploy the deployable constrictor from the delivery shaft after receiving the female patient'"'"'s cervix and assuming the second configuration to apply pressure about at least part of the patient'"'"'s cervix and to thereby at least partially occlude at least one of the uterine arteries; a sensor configured to detect at least one uterine artery and disposed on at least one of said delivery shaft and said deployable constrictor; and a guide configured to engage a cervix. - View Dependent Claims (29, 30, 31, 32, 33)

34. A method of occluding at least one uterine artery of a female patient, comprising:
-
providing a uterine artery occlusion device having an elongated delivery shaft, a deployable constrictor mounted on the delivery shaft which has at least one pair of opposed pressure-applying members with a first mounted configuration to receive a female patient'"'"'s cervix and a second deployed configuration to apply pressure to the patient'"'"'s cervix or vaginal tissue to occlude at least one of the patient'"'"'s uterine arteries and having a blood flow sensor to detect at least one uterine artery; locating the deployable constrictor in the first mounted configuration about the female patient'"'"'s cervix; detecting a uterine artery with the blood flow sensor; and deploying said deployable constrictor about said cervix in said second configuration to apply pressure to said cervix or vaginal surface and to occlude a uterine artery. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41, 42)

43. A uterine artery occlusion device, comprising:
-
a deployable constrictor means configured to receive and apply pressure to a patient'"'"'s cervix or vaginal surface and thereby occlude at least one of the patient'"'"'s uterine arteries; a delivery means configured to intravaginally advance said constrictor means to the patient'"'"'s cervix; a deployment means configured to deploy said constrictor means from said delivery means and to place said constrictor means about the cervix or uterus effective to occlude at least one of the patient'"'"'s uterine arteries; and at least one locating sensor means configured to detect a blood vessel.
