Tenaculum-like device for intravaginal instrument delivery
First Claim
1. An intravaginal device comprising:
- a guide rail having a proximal end, a distal end, and an outer surface extending between the proximal and distal ends thereof, wherein the outer surface of said guide rail includes a threaded section;
a collar mounted on the outer surface of said guide rail and having an internal lumen that allows sliding movement of said collar over the threaded section of said guide rail;
a driving member extending between said collar and the proximal end of said guide rail, said driving member having internal threads for engaging the threaded section of said guide rail;
a tissue grasping assembly including a first elongated element connected with the outer surface of said guide rail, and a second elongated element pivotally connected with said first elongated element and having a tissue grasping element at a distal end thereof; and
a medical instrument slidably mounted on the outer surface of said guide rail between said collar and the connection of said first elongated element with the outer surface of said guide rail, wherein rotation of said driving member in a first direction slides said collar toward the distal end of said guide rail which, in turn, urges said medical instrument toward the distal end of said guide rail.

Abstract
The invention is directed to tenaculum-like devices and systems for the intravaginal delivery of therapeutic or diagnostic devices and particularly for occluding a female patient'"'"'s uterine arteries in order to treat uterine disorders. Included are methods for grasping, manipulating and retaining tissue. The tenaculum-type device has a distal portion with a sound configured to enter a cervical os without causing undue trauma or discomfort to the patient, and a retention or tissue grasping mechanism with a grasping element such as a spike configured to engage and retain a patient'"'"'s cervix. The tenaculum-type devices embodying features of the invention may have an expandable distal tip to more securely be engaged within the patient'"'"'s uterine cervical canal.

11. An intravaginal device comprising:
-
a guide rail having proximal and distal ends, a longitudinal axis extending between the proximal and distal ends, and an outer surface extending between the proximal and distal ends thereof, wherein the outer surface of said guide rail includes a threaded section; a collar having an internal lumen aligned with the longitudinal axis of said guide rail and being adapted to allow sliding movement of said collar over the threaded section of said guide rail; a driving member mounted on the outer surface of said guide rail and extending between said collar and the proximal end of said guide rail, said driving member having a distal end with internal threads for engaging the threaded section of said guide rail and a proximal end accessible at the proximal end of said guide rail; a tissue grasping assembly including a first elongated element having a distal end connected with the outer surface of said guide rail, and a second elongated element pivotally connected with said first elongated element and having a tissue grasping element at a distal end thereof, wherein said driving member is advanceable toward the distal end of said guide rail for urging said collar to slide over the threaded section of said guide rail toward the distal end of said guide rail. - View Dependent Claims (12, 13, 14, 15, 16)

17. An intravaginal device comprising:
-
a guide rail having a proximal end, a distal end, and an outer surface extending between the proximal and distal ends thereof, wherein the outer surface of said guide rail includes a threaded section; a tissue grasping assembly coupled with said guide rail, said tissue grasping assembly including a first elongated element connected with the outer surface of said guide rail, and a second elongated element pivotally connected with said first elongated element and having a tissue grasping element at a distal end thereof; a collar mounted on the outer surface of said guide rail and having an internal lumen adapted to slide over the threaded section of said guide rail; a driving member mounted over the outer surface of said guide rail, said driving member having internal threads for engaging the threaded section of said guide rail; and a medical instrument slidably mounted onto the outer surface of said guide rail between said driving member and the distal end of said guide rail, wherein said driving member is rotatable in a first direction for sliding said collar toward the distal end of said guide rail which, in turn, engages and urges said medical instrument to slide over the outer surface of said guide rail and toward the distal end of said guide rail. - View Dependent Claims (18, 19, 20)
