A medical tool gripper for gripping a long medical tool includes a substantially hollow cylindrical main body and a fixing tool for fixing a medical tool to the main body. The main body has a main body inner space that extends over the entire longitudinal direction of the main body and in which the medical tool can be arranged, and a main body groove that is open on the outer periphery of the main body and communicates with the main body inner space over the entire longitudinal length of the main body. The main body groove includes a distal end portion including the distal end of the main body groove, and a proximal end portion including the proximal end of the main body groove and having an opening at a different position from an opening of the distal end portion in the circumferential direction of the main body.

An apparatus includes a tube configured for insertion into a body of a subject, the tube comprising a plurality of strips, which are angled obliquely with respect to a longitudinal axis of the tube, by virtue of the tube being shaped to define a plurality of slits having respective oblique proximal ends and respective oblique distal ends. The distal end of each of the slits is nested between the proximal end of a first other one of the slits and the proximal end of a second other one of the slits such that (i) one of the strips is disposed between the distal end of the slit and the proximal end of the first other one of the slits, and (ii) another one of the strips is disposed between the distal end of the slit and the proximal end of the second other one of the slits.

A guidewire stabilization mechanism for a catheter placement system can include an actuator button that can be actuated by the user to grip the guidewire in a locked position. With the guidewire locked relative to a housing of the stabilization mechanism a user can detach a needle hub from the housing and withdraw the needle proximally. A portion of the guidewire can pass through a needle slot to disengage the needle from the guidewire. The stabilization mechanism can prevent the guidewire from being dislodged from the vasculature as the needle is withdrawn. The stabilization mechanism can be biased towards the unlocked position, towards the locked position, can be bistable in both the locked and unlocked positions, or can be activated by the removal of the needle.

A catheter device is configured to include a main body portion that is bendable and is provided on a distal end side, two systems of wire ropes coupled to a distal end portion of the main body portion with a space in a predetermined first direction, and an operating portion that is operable by a user operation and is coupled to a proximal end side of the two systems of the wire ropes with a space in the first direction. The main body portion is bendable in the first direction due to a tension state of the two systems of the wire ropes by bending the operating portion in the first direction.

A system for traversing an arterial occlusion in an artery includes a housing sized to fit in a palm of a user, an elongate drive tube configured to be rotated by the housing, the drive tube including an axially extending passage, a cylindrical member, configured to be rotationally coupled to the drive tube, such that a distal tip of the cylindrical member may be delivered to a location adjacent the arterial occlusion when the cylindrical member is coupled to the drive tube, and wherein grasping and activating the housing such that the drive tube is rotated, thereby causes the distal tip of the cylindrical member to be rotated, the rotation of the distal tip including at least a component of linear oscillation.

The present invention relates to methods of transvascular retrograde access placement and to devices that facilitate these methods. For purposes of the present invention, transvascular retrograde access placement generally comprises the insertion of a vascular catheter into a central blood vessel through the puncturing of the central blood vessel from the inside of the central blood vessel with a needle or other similarly configured device, or a needle-tipped guidewire of the present invention, and exiting that needle from the patient through the skin rather than the traditional approach of inserting a needle from the outside of the skin surface to the inside of a blood vessel.

A medical clip for holding a medical device. The medical clip includes a first jaw and a second jaw rotatably coupled to the first jaw, the first jaw and the second jaw being rotatable with respect to each other between a closed position and an open position; an elastomeric insert configured to be positioned between the first jaw and the second jaw. The elastomeric insert defining a cavity having a cavity depth that receives a medical device between the first jaw and the second jaw. In the closed position, a distal face of the first jaw and the second jaw define a distal opening configured to receive a portion of the medical device through the distal opening; and, a proximal face of the first jaw and the second jaw define a proximal opening configured to receive a second portion of the medical device through the proximal opening.

An intraluminal guide wire may include an elongated shaft extending between a distal and a proximal end. The guide wire may include a user actuation segment positioned proximal to the proximal end of the shaft and configured for movement relative to the shaft. The guide wire may include a core wire affixed to the user actuation segment and the distal end of the shaft. The guide wire may also include an inner member having a proximal end situated at least partially within and fixed relative to the user actuation segment and a distal end situated partially within the shaft, the core wire passing through the inner member. The guide wire may be configured with a distal segment of the inner member within the shaft exhibiting a friction-based restraint on movement within the shaft. The friction-based restraint on movement may be a frictional force between the inner member and the shaft.

A deep vein intravenous introducer has a wheel located toward the front end of the device that can be rotated by the index finger of the user. After placement of the needle in the lumen of the vessel, the user rotates the wheel, which turns a drive wheel. The drive wheel has an outer surface that advances the guide wire through the center of the needle and into the patient. Once the guide wire is advanced into the vessel lumen the catheter can be advanced over the guide wire with a hub or finger tab on the catheter close to the index finger. The operation can be performed by one hand without moving the hand from its initial position.

A balloon catheter and method for manufacturing are disclosed in which the fracturing of the vicinity of a proximal opening portion formed by an inner shaft can be prevented. A distal side of an inner shaft included by a balloon catheter is disposed in a lumen of an outer distal shaft, and a proximal side of the inner shaft is disposed on an outer surface of an outer proximal shaft, and the inner shaft forms a proximal opening portion which opens on an outer surface side of the outer proximal shaft. The inner shaft has a first region and a second region disposed on a proximal side of the first region. The first region is fixed to the outer surface of the outer proximal shaft. The second region is not fixed to the outer surface of the outer proximal shaft.
