Abstract: According to an aspect, an apparatus includes a handle portion having a first portion and a second portion, a distal portion disposed opposite the handle portion, the distal portion having a first connector contacting portion and a second connector contacting portion, the first connector contacting portion being configured to move with respect to the second connector contacting portion, the distal portion being configured to be disposed in a first configuration and a second configuration, the first connector contacting portion being disposed a first distance from the second connector contacting portion when the distal portion is in the first configuration, the first connector contacting portion being disposed a second distance from the second connector contacting portion when the distal portion is in the second configuration, the second distance being greater than the first distance, and a biasing member configured to bias the distal portion into the first configuration.

Abstract: A guidewire control assembly may hold a guidewire stationary while allowing for rotation of a catheter shaft disposed over the guidewire. The guidewire control assembly may include a housing with a passage for receiving the guidewire, a clutch mechanism connected to the housing and actuatable to selectively grip and release the guidewire disposed in the passage, and an interface rotatably connected to the housing. The interface may receive the catheter hub attached to the catheter shaft and may allow for torquing the catheter hub.

Abstract: The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to medical devices and systems with control knobs designed for improved usability and ergonomics. For example, the control knobs of the present disclosure may include surface features for improved gripping, surface features for improved perception of medical device orientation within a patient and/or knobs dimensioned for improved thumb reach and reduced torque.

Abstract: A medical device includes a handle with a proximal arm and a distal arm. The proximal arm and the distal arm are pivotable via a joint. The medical device also includes a tube coupled to the distal arm and a drive wire. A distal portion of the drive wire includes an expandable end effector. A portion of the drive wire is positioned within the tube, and a different portion of the drive wire extends proximally of the distal arm and is coupled to the proximal arm.
