SYSTEMS AND METHODS FOR EMBOLIC IMPLANT DETACHMENT
An aneurysm treatment system can include an embolic implant, a delivery system, and an introducer sheath that are collectively designed so that the combination of the introducer sheath and the delivery system can be used as a deployment apparatus for the embolic implant. The introducer sheath can be moved proximally against an interference feature attached to a pull wire to cause the interference feature to separate from the delivery tube, thereby pulling the pull wire and releasing the implant. Alternatively, the treatment system can include an embolic implant and a delivery system that includes a delivery tube, a proximal extension, a pull wire attached to the proximal extension, and a disconnection feature that can be broken to allow the proximal extension and the pull wire to be translated proximally in relation to the delivery tube.

The bendable shaft has a proximal end attached to the distal end of the elongated shaft along a shaft axis, the bendable shaft configured to bend only within a pivot plane that is defined by the shaft axis and a pivot axis that is orthogonal to the shaft axis. The steerable tip is attached to a distal end of the bendable shaft and includes a camera and a light emitter. The offset balloon is attached to the external surface of the elongated shaft and has an internal volume in fluid communication with a fluid port in the elongated shaft. The handle includes at least one lever in mechanical communication with the bendable shaft to adjust a customizable angle of the steerable tip measured between the shaft axis and the tip axis.

An instrument port includes an elongated shaft, a flexible shaft, a steerable tip, a handle, and a working tube. The elongated shaft extends along a shaft axis. The flexible shaft is attached to a distal end of the elongated shaft, the flexible shaft configured to bend only within a pivot plane that is defined by the shaft axis and a pivot axis that is orthogonal to the shaft axis. The steerable tip is attached to the distal end of the shaft, the steerable tip extending along a tip axis. The handle is attached to a proximal end of the elongated shaft, the handle including a lever in mechanical communication with the flexible shaft to adjust a customizable angle of the steerable tip measured between the shaft axis and the tip axis. The working tube is disposed in the elongated shaft and flexible shaft.
INSTRUMENT PORT FOR EPICARDIAL ABLATION WITH INFLATABLE BALLOON
An instrument port includes an elongated shaft, a steerable tip, an offset balloon, and a working tube. The elongated shaft has proximal and distal ends and extending along a shaft axis, the elongated shaft having a fluid port defined in an external surface at the distal end of the elongated shaft. The steerable tip is attached to the distal end of the shaft. The offset balloon is attached to the external surface of the elongated shaft, the offset balloon having an internal volume in fluid communication with the fluid port, the offset balloon having an inflated state and a deflated state, wherein in the inflated state the offset balloon is radially asymmetrically inflated with respect to the shaft axis. The working tube is disposed in the elongated shaft, the working tube forming a working channel to receive a medical instrument.
INSTRUMENT PORT FOR EPICARDIAL ABLATION WITH ANATOMICAL EPICARDIAL STRUCTURES AND REAL-TIME LESION IMAGE PROCESSOR
A method for controlling an epicardial ablation procedure comprises (a) inserting an instrument port comprising an ablation tool, an optical camera and an optical light emitter into an epicardial cavity proximal to a target region; (b) providing optical light into said epicardial cavity through said optical light emitter to illuminate said target region; (c) obtaining a first image of said target region using said optical camera; (d) steering a tip of said ablation tool towards said target region; (e) applying an ablation energy to said target region using the ablation tool so as to form a lesion in or on said target region; (f) obtaining a second image of said target region using said optical camera; and (g) processing at least one of said first and second images in an image processor so as to determine a characteristic of said lesion.
MIXER SHEATH FOR A VASCULAR CATHETER
The application relates to vascular catheters, in particular to vascular catheter systems (100) which are configured to mix blood. Aspects relate to a mixer sheath (110) for a vascular catheter, a method of manufacturing a mixer sheath, a catheter sheath, a catheter, a method of deploying a vascular catheter, a method of removing a vascular catheter, a method of deploying one or more blood mixing elements, a method of using a catheter system and a method of reversing the deployment of a blood mixing element. The mixer sheath comprises a tube having a wall patterned with a line of weakness (212) which is configured to cause buckling of a portion of the tube wall when a longitudinal compression force is applied to the tube to form a blood mixing element (111) which extends radially outwards with respect to a location of the portion of the tube wall prior to buckling.
