METHODS AND APPARATUS FOR JOINT DISTRACTION

A method of treating a patient's joint having opposing joint surfaces includes providing an elongate member having a proximal end, a distal end and an expandable member near the distal end. The expandable member is positioned in the joint between the joint surfaces and expanded so as to separate the joint surfaces away from one another into a distracted position. The joint is manipulated while in the distracted position so that the joint is distracted and in flexion. A diagnostic or therapeutic procedure is then performed on the joint while maintaining the joint in the flexed and distracted position.

A CATHETER SYSTEM FOR DELIVERY OF A URETERAL CATHETER
20170274178 · 2017-09-28 ·

A catheter system for delivery of a ureteral catheter in a ureter includes a ureteral catheter, a pusher catheter to deliver the ureteral catheter at a desired location, and a connection device, to connect, in an assembled state a distal end of the pusher catheter to a proximal end of the ureteral catheter. The catheter further includes a releasable tether to secure a connection of the connection device between the ureteral catheter and the pusher catheter. The connection device includes a connector element provided on the ureteral catheter, and a sleeve provided on the pusher catheter, where the connector element is configured to be arranged in the sleeve, and that the tether is arranged to prevent unintentional release of the connector element out of the sleeve.

Flexible and steerable device
11241557 · 2022-02-08 ·

A device, a method of making a device and a method of inserting a device into a tubular path. The device includes a tubular sheath with one or more helical slots formed therein and a control element that fits within the sheath. In one form, the device is an endoluminal device that simultaneously improves flexibility and structural rigidity though variations in one or both of slot width along the length of the slot and slot pitch along the length of the tubular sheath. When the operator pulls at the proximal end of the control element while holding the outer sheath in place, the slots will tend to close in a preferential manner such that more precise control of device length and bending is enabled, while simultaneously providing improvements in structural rigidity during device insertion and navigation through a body lumen or related tubular member where tortuous paths may be encountered along the member path.

CATHETER HUB WITH SEALED ACCESS PORT

A catheter hub for use with a medical device and a catheter, the hub includes a hub body defining a fluid passageway in communication with a first aperture. Optionally, the hub body defines a second aperture that intersects the first aperture. The hub body attaches to the catheter wherein the fluid passageway and the catheter are aligned for fluid flow therethrough. The first aperture extends from and communicates with the fluid passageway to an exterior surface of the hub body and the first aperture configured to receive the medical device. The second aperture extends from and communicates with the first aperture and the exterior surface. A sealing element is sized for and positioned in either the first or the second apertures. The sealing element is configured to receive the medical device and seal both of the first and the second apertures.

DRAINAGE CATHETER HUB WITH A SEMI-COMPRESSED SUTURE SEAL

Described are drainage catheter hub devices which seal the hub from leakage when connected to a catheter. The catheter hub includes a hub body having an aperture with a sealing element mounted therein and a fluid passageway that communicates with the aperture. The fluid passageway and sealing element are configured to receive a tension member. A lever arm attached to the hub body is operable to secure the position of the tension member in the sealing element in a locked position or allow movement of the tension member through the sealing element in an unlocked position. The lever arm is configured to engage and compress the sealing element to block fluid flow through the sealing element and the aperture when the lever arm is in any position. The hub body may include a centering tab to align the tension member along a longitudinal axis of the hub body.

A medical device includes an insertion tube, having a distal end for insertion into a body of a subject and an opening at the distal end. A lumen, which includes a flexible tube which passes longitudinally through the insertion tube so as to communicate with the opening at the distal end of the insertion tube, is secured under tension inside the insertion tube.

CATHETER TIP PASSIVE CONTROL DEVICE AND RELATED SYSTEMS AND METHODS

A vascular access device to passively open a fluid path within a vasculature. The vascular access device may include a catheter and a guidewire. The catheter may have a proximal end, a tip, and a length of tubing therebetween. The guidewire may extend along the length of tubing and may include a bent portion. At least a portion of the length of tubing may substantially conform to the bent portion such that the tip of the catheter avoids an obstruction within the vasculature.
