Abstract
An implantable medical device includes a functional unit, an introducer unit for introducing and/or navigating the functional unit in a lumen of body conduit(s) of a subject, and an elongated operable element connectable to a controller for operating the functional unit though the elongated operable element in a lumen of body conduit(s) of the subject. The functional unit, introducer unit, and elongated operable element may be in a slidable relationship for assembling and unassembling the implantable medical device in vivo. The implantable medical device is implantable, explantable, and operable in a lumen of body conduit(s) of a subject according to related methods.
Core Innovation
The invention relates to an implantable medical device that includes a functional unit and an introducer unit having a longitudinal guide hole configured to slidably receive an elongated operable element. The elongated operable element is connectable to and extendable from the functional unit, and is manipulated from a distal end portion so that the functional unit is assembled in vivo to the proximal end portion of the introducer unit. The introducer unit is introduced in a lumen of a subject’s body conduit with a distal end portion configured to atraumatically introduce the introducer unit for implanting the functional unit.
The device architecture enables in vivo assembly and operational coupling while the elongated operable element extends from the functional unit through the introducer unit. The longitudinal guide hole guides the elongated operable element during assembling in vivo, and the distal end portion supports atraumatic introduction, including a tapered shape. Additional structural relationships include configurations where an elongated operable element can be received through a distal cavity of the introducer unit and where distal geometry and interfacing elements are provided.
The invention further includes delivery and implantation concepts in which the implantable medical device is introduced through a first percutaneous intraluminal access and advanced up to a second percutaneous intraluminal access, with an end portion externalized through the second access. The device is operated in the lumen from the externalized end portion, and dependent refinements include operating via manipulation associated with assembling using the elongated operable element. The overall approach is also compatible with use adjuncts that support tool-based movement and routing, including a guidewire and a capture element configured to be captured by a tool within the body conduit lumen to move the functional unit.
Claims Coverage
Two independent claims are provided: one directed to an implantable medical device and one directed to a method of implanting the implantable medical device. The independent claims collectively describe device structure enabling in vivo assembly and atraumatic introduction, and a procedural sequence involving two percutaneous intraluminal accesses, externalization, and operating the device from the externalized end portion, including manipulation with an elongated operable element.
Slidably receiving elongated operable element in introducer longitudinal guide hole for in vivo assembly
An implantable medical device comprising a functional unit, an elongated operable element connectable to and extendable from the functional unit, and an introducer unit having a longitudinal guide hole extending at least partially between a proximal end portion and a distal end portion, wherein the longitudinal guide hole is configured to slidably receive the elongated operable element therein for assembling in vivo the functional unit to the proximal end portion of the introducer unit by manipulation of the elongated operable element from the distal end portion when the elongated operable element is connected to the functional unit.
Atraumatic introduction of introducer distal end portion into body conduit lumen
An introducer unit wherein the distal end portion is configured to atraumatically introduce the introducer unit in a lumen of a subject's body conduit for implanting the functional unit in the lumen of the subject's body conduit.
Implanting via first and second percutaneous intraluminal access with externalized end portion
A method of implanting an implantable medical device in a lumen of a subject's body conduit comprising introducing the implantable medical device in the lumen through a first percutaneous intraluminal access, advancing the implantable medical device in the lumen up to a second percutaneous intraluminal access, externalizing an end portion of the implantable medical device through the second percutaneous intraluminal access, and operating the implantable medical device in the lumen from the end portion.
The claim set is centered on an introducer longitudinal guide hole that slidably receives an elongated operable element to assemble the functional unit in vivo at the introducer proximal end while enabling distal atraumatic introduction, and on a two-access implantation workflow in which the device is introduced and advanced between percutaneous intraluminal accesses, an end portion is externalized through the second access, and the device is operated from that end portion.
Stated Advantages
Atraumatic introduction of the introducer unit into a lumen of a subject’s body conduit for implanting the functional unit.
Documented Applications
Implanting an implantable medical device in a lumen of a subject’s body conduit, including operating the device in the lumen from an externalized end portion.
Transcatheterly implantable blood pump implantation and operation in a subject’s body conduit lumen.
