US Classification:

600486, 604 9601, 604 9501, 606129, 600300

Abstract:

In one example, this disclosure is directed to a kit for intravascular implantation of an implantable medical device within a patient, the kit comprising an elongated outer sheath forming an inner lumen with a distal opening, the outer sheath sized to traverse a vasculature of the patient, and an elongated inner sheath with an inflatable member at its distal portion. The inflatable member is inflatable from a proximal end of the inner sheath to close-off the distal opening of the outer sheath when inflated. The inner sheath further includes a stopper proximally located relative to the inflatable member. The inflatable member is remotely controllable from a proximal end of the inner sheath to retract in a proximal direction towards the stopper. The inflatable member can be retracted in a proximal direction towards the stopper and past an implantable medical device positioned within a distal portion of the outer sheath.

Abstract:

In one example, this disclosure is directed to a kit for intravascular implantation of an implantable medical device within a patient, the kit comprising an elongated outer sheath forming an inner lumen with a distal opening, the outer sheath sized to traverse a vasculature of the patient, and an elongated inner sheath with an enlarged distal portion, wherein the enlarged distal portion is configured to substantially fill the inner lumen and close-off the distal opening of the outer sheath. The enlarged distal portion is slidable relative to the outer sheath. The inner sheath further includes a tether with a helical element that is remotely controllable from a proximal end of the inner sheath to release the implantable medical device from a distal portion of the outer sheath.

Abstract:

In one example, this disclosure is directed to a kit for intravascular implantation of an implantable medical device within a patient comprising an elongated outer sheath forming an inner lumen with a distal opening, the outer sheath sized to traverse a vasculature of the patient, and an elongated inner sheath with a stopper. The inner sheath further includes a tether configured to form a loop on a distal side of the stopper, the loop being configured to engage a looped element of the implantable medical device to couple the implantable medical device to the inner sheath. The stopper is slidable relative to the outer sheath. The tether is configured to release the looped element of the implantable medical device from the inner sheath by opening the tether loop when a portion of the stopper is located distally relative to the distal opening of the outer sheath.

International Classification:

A61B 19/00

US Classification:

606129

Abstract:

A delivery system assembly includes an elongate inner member that extends distally through a lumen of an elongate outer tube of the assembly; the outer tube is moveable relative to the inner member between first and second positions to deploy an implantable medical device that is held within the outer tube lumen. The inner member may include a flared distal end that abuts, and preferably conforms to, the proximal end of the device, when the device is held within the outer tube lumen. The assembly further includes a stability sheath that surrounds a limited length of the outer tube, in proximity to the handle, to provide an interface for both an operator, who handles the assembly, and for an introducer sheath that provides passage for the assembly into the venous system, so that movement of the outer tube is not hindered by either during device deployment.

International Classification:

A61M 25/00
A61M 25/06
A61M 25/02

Abstract:

An introducer extension with an extended, gradually curved section outside of the body enables a clinician to use an access site positioned across the body of that patient. An optional flexible or extendable section of the introducer extension allows a clinician to customize the shape of the introducer extension to a particular patient or clinician preference. The introducer extension includes a tubular sidewall extending along a longitudinal axis from a proximal end of the introducer extension to a distal end of the introducer extension and defining a lumen extending along the longitudinal axis. The tubular sidewall is configured to define a curved configuration having at least one curve between the proximal end and the distal end. The distal end is configured to couple to an introducer sheath. The lumen is configured to allow passage of a medical device.

International Classification:

A61M 25/01
A61M 25/00

Abstract:

In some examples, a catheter includes a hub assembly, an elongate member, and a plurality of support wires extending along a length of the elongate member. The plurality of support wires is configured to expand radially outward from the elongated body to help anchor a distal portion of the catheter within the vasculature the patient and provide a backup support to the elongate member, e.g., to reduce pushback on the catheter when a treatment device is advanced past the distal tip of the catheter.
