Abstract
An instrument positionable with respect to a body valve in the body of a living subject for performing a predetermined procedure on the living subject at a predetermined location relative to the body valve. The instrument includes: a movement sensor for sensing movements of the body valve; an effective portion for performing the predetermined procedure when the effective portion is at the predetermined location; and an effective portion positioner for positioning the effective portion in the living subject. The effective portion is positionable using the effective portion positioner in response to the movements sensed by the movement sensor for positioning the effective portion at the predetermined location in order to perform the predetermined procedure.
Core Innovation
The invention provides an instrument positionable with respect to a body valve in the body of a living subject for implanting anchors into living tissue at a predetermined location relative to the body valve. The instrument uses a movement sensor for sensing movements of the body valve and an effective portion positioner for positioning an effective portion in the living subject, where the effective portion includes an anchor implanting mechanism that implants anchors when the effective portion is at the predetermined location.
The movement sensor includes a deformable element having a configuration, a rigidity and dimensions such that the deformable element is substantially freely deformable by the valve when abutting against the valve. The movement sensor further includes a deformation sensor for sensing deformations of the deformable element, and the sensed movements and deformations are used to position the effective portion at the predetermined location.
In one implementation, the deformable element is substantially freely deformable and substantially elongated, defining a deformable element proximal end and a deformable element distal end. The deformable element proximal end is fixed with respect to the effective portion and located substantially adjacent to the effective portion, while the deformable element distal end is substantially freely movable relative to the effective portion.
Claims Coverage
The partial content provides two independent claims. Across these independent claims, the core coverage includes valve movement sensing using a freely deformable deformable element with deformation sensing, and positioning an effective portion to actuate an anchor implanting mechanism or perform a predetermined procedure at the location indicated by sensed movements and deformations.
Valve-relative instrument positioning for anchor implantation at a predetermined location
An instrument positionable with respect to a body valve in a living subject for implanting anchors into living tissue at a predetermined location relative to the body valve, comprising a movement sensor sensing valve movements, an effective portion with an anchor implanting mechanism for implanting anchors when at the predetermined location, and an effective portion positioner positioning the effective portion in response to movements sensed by the movement sensor.
Freely deformable valve abutting movement sensor with deformation sensing for positioning
The movement sensor includes a deformable element having a configuration, a rigidity and dimensions such that the deformable element is substantially freely deformable by the valve when abutting against the valve, and a deformation sensor for sensing deformations of the deformable element, where the effective portion is positionable using the effective portion positioner in response to the movements sensed by the movement sensor.
Elongated deformable element with fixed proximal end and freely movable distal end
The movement sensor includes an elongated deformable element defining a deformable element proximal end and a substantially opposed deformable element distal end, with the deformable element proximal end fixed with respect to the effective portion and located substantially adjacent to the effective portion, and the deformable element distal end substantially freely movable relative to the effective portion.
Effective portion enabling predetermined procedure at a predetermined location using valve movement sensing
An instrument positionable with respect to a body valve for performing a predetermined procedure on the living subject at a predetermined location relative to the body valve, comprising a movement sensor with a freely deformable deformable element abutting the valve and a deformation sensor sensing deformations, an effective portion for performing the predetermined procedure when the effective portion is at the predetermined location, and an effective portion positioner for positioning the effective portion in response to the movements sensed by the movement sensor.
The independent claims cover a valve-relative positioning instrument in which valve movements are sensed via a deformable element that abuts the valve and a deformation sensor that senses deformations, and an effective portion is positioned accordingly at a predetermined location to either implant anchors via an anchor implanting mechanism or perform a predetermined procedure. One independent claim further specifies an elongated deformable element with a proximal end fixed relative to the effective portion and a distal end substantially freely movable relative to the effective portion.
