A hollow probe enabling insertion and accommodation of endoscopic and other instruments advancing within a lumen includes a central valve unit featuring a central bore and at least one valve for controlling the introduction and withdrawal of fluid into the central bore. A sliding tubular sheath is movably disposed inside the central valve unit. An impermeable flexible sleeve is sealingly anchored to the central valve unit and folds over to cover both the inside and outside of the sheath to sealingly envelop the sheath and contain the fluid, together with the valve unit, while allowing sliding of the sleeve-covered-sheath. An endoscope adapter is mountable to the proximal end of the sleeve-covered-sheath, for allowing insertion of the endoscope through the adapter into the sleeve-covered-sheath, includes at least one gasket for sealing at least one gap between the endoscope and the sleeve-covered-sheath for withholding fluids from escaping.

An introducer assembly includes a catheter having a proximal end, a distal end extending to a distal tip of the introducer assembly, and an outer catheter wall. The catheter includes a medical device holding portion proximate the distal end, a guide wire lumen extending between the proximal and distal ends, and a side opening extending through the outer wall to the guide wire lumen. The side opening and the guide wire lumen are simultaneously open and the guide wire lumen and side opening are able to receive a guide wire therethrough. The catheter is flexible at least in the location of the side opening. The catheter also includes a plurality of one stiffening mandrel lumens extending from the proximal end and a plurality of stiffening mandrels.

The present disclosure relates to medical devices that that include the following: a flexible elongate tube having a proximal end and a distal end configured to be directed toward an opening of a body lumen; a first lumen extending from the distal end of the tube proximally along the tube and having a fluid connection for a fluid source at its proximal end; a second lumen extending from the distal end of the tube proximally along the tube, the second lumen configured to accept a guidewire extending along the second lumen; and a wire filament extending along the elongate tube, a distal end of the filament connected to the distal end of the elongate tube, a proximal portion of the wire extending at least partially along the elongate tube, and a distal portion of the wire extending external to the elongate tube.

An introducer assembly (10) includes a catheter (12) having a proximal end (14), a distal end (16) extending to a distal tip of the introducer assembly, and an outer catheter wall. The catheter (12) includes a medical device holding portion (34) proximate the distal end, a guide wire lumen (100) extending between the proximal and distal ends, and a side opening (50) extending through the outer wall to the guide wire lumen. The side opening (50) and the guide wire lumen (100) are simultaneously open and the guide wire lumen and side opening are able to receive a guide wire therethrough. The catheter (12) is flexible at least in the location of the side opening, such that a guide wire (28) fed from the distal end (16) can pass through to the proximal end (14) when the catheter is substantially straight and can pass from the distal end through the side opening (50) when the catheter is curved at the location of the side opening. The catheter (12) also includes a plurality of one stiffening mandrel lumens (104, 106) extending from the proximal end (14) and a plurality of stiffening mandrels sized to fit within the stiffening mandrel lumens and in some forms able to slide therewithin and in other forms enclosed within the stiffening mandrel lumens. The mandrels have different lengths disposed along the length of the catheter and can be of substantially uniform diameter.

A thrombectomy catheter deployment for operation of a thrombectomy catheter may include a stand alone drive unit and a disposable pump/catheter assembly which is manually placed into a carriage assembly in the drive unit. The pump/catheter assembly may have a plurality of preconnected components including a tubular structure and a thrombectomy catheter connected thereto. A barcode reader may sense specific operational data pertaining to an individual pump and may provide an interface for operation of the reciprocating linear actuator.

A flow directed device adapted to be guided by a fuid, such as blood, flow within a tubular structure such as a blood vessel is disclosed, said device comprising a proximal end (100), a distal end (101) and an elongated body (102) in between defining a longitudinal axis (103), characterized in that said distal end (101) comprises a ferromagnetic area or structure (300) capable of deflecting the distal end (101) when subjected to an external magnetic field. A system comprising the device, as well as method of use of the device, are also disclosed.

A medical device comprising a first tube, a second tube configured to sheath at least a portion of the first tube and configured to translate along a length of the first tube, an expandable device at a distal portion of the first tube, the expandable device having a collapsed state and an expanded state, a patch surrounding at least a portion of an outer surface of the expandable device, and a connector for holding the patch to the expandable device when the second tube covers the patch and the expandable device and for releasing the patch from the expandable device after the second tube uncovers the patch and the expandable device.

Provided is a system for advancing an article along a path. The system may include a head member, a dispatching member, and an eversion sleeve. Also provided is a method for assembling a system for advancing an article along a path.

Apparatus for controlling motion of an invasive probe relative to a sheath enclosing the probe. The apparatus includes an outer casing, configured for connection to the sheath. The apparatus further includes a drive mechanism, fixedly connected to the outer casing. The drive mechanism has a first set of components, configured to translate the probe along a direction parallel to as axis of the probe, in order to advance and retract the probe with respect to the sheath in a translational stepwise manner. The drive mechanism also includes a second set of components, configured to rotate the probe around the axis of the probe, in order to rotate the probe clockwise and counter-clockwise, with respect to the sheath, in a rotational stepwise manner.

A catheter assembly may include a catheter adapter having a proximal end, a distal end, and a lumen extending therebetween. A wedge adapter may be retained within the lumen and have a wedge coupled thereto. The wedge may be configured to retain an end of a catheter such that a tip of the catheter extends through the distal end of the catheter adapter. A control feature may extend through an end or side wall of the catheter adapter. The control feature may be configured to manipulate the wedge to control a position of the tip of the catheter to open a fluid path within a vasculature.
