Abstract: A valve fixation device may comprise a unitary elongate member that is biased towards a closed configuration wherein at least a pair of tissue engaging surfaces of the elongate member are held adjacent to each other by a bias force. The bias force is at least equal to a valve leaflet grasping force, enabling the fixation device to grasp and retain leaflets as part of cardiac treatment. A delivery tool including a spreader may independently translate the tissue engaging surfaces to enable cardiac leaflets to be captured and retained by and/or between the tissue engaging surfaces. The valve fixation device may include at least two arms, each of which may be independently controlled to grasp and capture opposing leaflets of a valve, such as the anterior and posterior leaflets of a mitral valve, to reduce the size of the valve opening and improve cardiac performance.

Abstract: A medical device may include a plurality of links reciprocally movable between a loose configuration having a first rigidity and a compact configuration having a second rigidity greater than the first rigidity, wherein application of a force to a distalmost link of the plurality of links when the plurality of links are in the loose configuration causes the plurality of links to change orientation relative to one another, and application of the force to the distalmost link when the plurality of links are in the compact configuration does not cause the plurality of links to change orientation relative to one another.

Abstract: The present disclosure is directed to a valve structure that comprises a flexible structure having a distal portion configured for attachment to a first member and a proximal portion configured for attachment to a second member. The flexible structure is configured such that when the first member is extended distally relative to the second member, the flexible structure adopts a reduced width profile and such that when the first member is retracted proximally relative to the second member to a point of maximal retraction, the flexible structure adopts an expanded width profile, which is more resistant to deformation due to fluid pressure in a proximal direction than it is to deformation due to fluid pressure in a distal direction. The present disclosure is also directed to devices and methods pertaining to such a valve structure.

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.
