Abstract: Some embodiments of a medical device anchor system include an anchor device that receives a catheter (or other medical instrument) and secures the catheter in place relative to a skin penetration point. In some embodiments, the anchor device can secure the catheter in an operative position relative to the skin without the use of sutures or skin tapes. In particular embodiments, the anchor device can be adjusted to a folded condition so that subcutaneous anchors are partially rotated prior to removal from the skin penetration point.

Abstract: Introducer sheath systems including a pressure regulator operably coupled to a hemostatic valve, wherein the pressure regulator includes a chamber filled with a gas that is fluidly isolated from the hemostatic valve. The introducer sheath systems may include a tubular sheath, a hub assembly, and a dilator disposed therein connected to a proximal end of the sheath; the hub assembly including a housing and a hemostatic valve disposed therein; a pressure regulator connected to the hub and in fluid communication with the hemostatic valve; and a sealed chamber defined by the pressure regulator, the chamber having an interior, wherein the interior of the chamber is filled with a gas that is fluidly isolated from the hemostatic valve.

Abstract: Some embodiments of a medical device anchor system include an anchor device that secures a medical instrument (such as a catheter or the like) in place relative to a skin penetration point using subcutaneous anchors. In some implementations, the anchor device can be installed using a technique in which the subcutaneous anchors undergo relatively little or no flexing when being inserted through the skin into the subcutaneous region between the skin and underlying muscle tissue which may be occupied by fatty tissue.

Abstract: An apparatus includes a handle assembly, a shaft assembly, an end effector, and an auto-tensioning feature. The handle assembly includes a body and a plunger. The shaft assembly includes an external sheath that is fixed to the handle body and an interior shaft that is coupled to the plunger. The interior shaft is slidable relative to the external sheath. The end effector is configured to encompass a bodily lumen and includes a flexible member extending distally from the interior shaft. A first coupling element is fixed to the distal tip of the flexible member. A second coupling element is fixed to the external sheath. The first and second coupling elements are magnetically attracted to each other and are biased toward each other such that the flexible member defines an adjustable loop. The auto-tensioning feature is configured to bias the plunger portion proximally relative to the handle body.

Abstract: Some embodiments of a medical device anchor system include an anchor device that receives a medical instrument (such as a catheter or the like) and secures the instrument in place relative to a skin penetration point. In some circumstances, the anchor device may allow the anchor device to be used after medical instrument is already in place without the need for a second penetration point for the anchor device.

Abstract: Some embodiments of a medical anchor device include an elongate body coupled with deployable subcutaneous anchors to secure a catheter instrument (or other medical instrument) in place relative to a skin penetration point. In some circumstances, the elongate body may be in the form of catheter hub body, and the subcutaneous anchors can be deployed from the hub body by adjustment of a movable actuator. A locking member can interact with the actuator so as to retain the actuator in the deployed orientation during the medical procedure.

Abstract: A sphincter augmentation device includes a plurality of bodies and a flexible band coupled with the bodies. The bodies define a first circumferential portion of the device and are magnetically biased toward one another. The flexible band defines a second circumferential portion of the device such that the bodies are arranged non-axisymmetrically about a central axis of the device. The device is sized to be positioned around a human urethra so that the bodies and the flexible band bear inwardly against the urethra. The device is configured to transition between a radially expanded state and a radially contracted state by the magnetic bias of the bodies to constrict the urethra.
