Abstract: Anchor delivery systems and methods for repairing a valve inside a body, such as a heart valve, may include a delivery catheter having a distal end comprised of two or more rotatably coupled knuckles. An anchor delivery mechanism is disposed distally of the two or more knuckles, and includes a first pincer arm having a distal end and a proximal end rotatably coupled to a distal end of the anchor delivery mechanism at a first connection point, and a second pincer arm having a distal end and a proximal end rotatably coupled to the distal end of the anchor delivery mechanism at a second connection point opposite the first connection point. In a closed position, the distal ends of the first and second pincer arms are positioned together. In an open position, the distal ends of the first and second pincer arms are rotated apart from each other.

Abstract: Anchor delivery systems and methods for repairing a valve inside a body, such as an atrioventricular valve, may include an anchor delivery device including a sheath for at least partially retaining an anchor in a collapsed form. The anchor delivery device may be configured to deliver the anchor to the atrioventricular valve. The anchor and an adjacent anchor may be connectable to each other in an expanded form, to link a series of anchors implanted at least partially around the atrioventricular valve. In some embodiments, the anchors may be connectable by a connecting member, such as a pledget, or a material disposable on a bulb of the anchor. In other embodiments, a bulb of the anchor and a bulb of the adjacent anchor may be configured to be directly interlocked.

Abstract: A heart valve anchor apparatus may include a body having a proximal portion and a distal portion. The body may include a first radially expandable portion at the proximal portion of the body, a second radially expandable portion at the distal portion of the body, and a root portion extending from the first radially expandable portion to the second radially expandable portion, the root portion having an outer extent. The first radially expandable portion may be configured to self-expand to an outer extent greater than the outer extent of the root portion when radially unconstrained. The second radially expandable portion may be configured to self-expand to an outer extent greater than the outer extent of the root portion when radially unconstrained. In an unstressed configuration, the body may define a longitudinal centerline that extends away from a plane tangent to the root portion.

Abstract: Implantable devices formed of materials which are not readily imageable, and which may shift from a delivery configuration to a deployment configuration upon deployment, are delivered and deployed with a deployment/delivery device having sensors generating a signal indicating contact of the delivery/deployment device with tissue to guarantee purchase of the implantable device with tissue upon deployment. The implantable device may be a tissue anchor with talons which shift from a delivery configuration to a deployed configuration. The sensors may be positioned along a distal end of the delivery/deployment device to indicate purchase of the device with tissue, to ensure purchase of the talons with tissue upon deployment. The sensors may include at least three sensors, which may be spaced apart from one another, to indicate full contact of the distal end of the delivery/deployment device with tissue. The sensors may optionally be aligned with the talons.

Abstract: A medical device for cutting a suture during a minimally invasive procedure may include an elongate shaft having a proximal end, a distal end, and a central longitudinal axis, a handle disposed at the proximal end of the elongate shaft, the handle including an actuation mechanism, and a cutting blade disposed proximate the distal end of the elongate shaft. The cutting blade is axially translatable within the elongate shaft in response to operation of the actuation mechanism. The elongate shaft includes a distal port to receive a suture. The elongate shaft includes a transverse slot extending inward from an outer surface of the elongate shaft generally perpendicular to the central longitudinal axis. The elongate shaft includes a suture lumen extending from the distal port axially within the elongate shaft to the transverse slot. The cutting blade intersects the transverse slot adjacent the suture lumen.

Abstract: A medical system includes an introducer device having an elongate shaft defining a shaft lumen and a hub secured to a proximal region of the elongate shaft. The hub includes a primary channel extending through the hub and fluidly coupled with the shaft lumen and a secondary channel extending through the hub and fluidly coupled with the shaft lumen. A guide catheter is adapted to be advanced through the secondary channel and into the shaft lumen. A guidewire is adapted to be advanced through the secondary channel and into the shaft lumen. A working catheter is adapted to be advanced through the primary channel and into the shaft lumen when the guide catheter is positioned with a distal end of the guide catheter within the secondary channel, the working catheter including a catheter shaft including a distal region that is adapted to releasably engage the guidewire.

Abstract: A medical device for cutting a suture during a minimally invasive procedure includes an elongate shaft, a handle housing disposed at the proximal end of the elongate shaft, and a cutting blade disposed proximate the distal end of the elongate shaft. A proximal portion of the handle housing includes an actuation mechanism including a lever arm having a first portion disposed outside of the handle housing and extending distally from the proximal portion of the handle housing. Translation of the first portion of the lever arm relative to the handle housing axially translates the cutting blade within the elongate shaft. A medical device system may include a stand configured to support at least one medical device and a medical device securable to the stand.
