  • Patent number: 10391310
    Abstract: A gastrointestinal stimulation apparatus and methods with an electronic controller and a flexible and stretchable electrode array with a central branch and orthogonal bilateral branches that wrap around a section of the gastrointestinal tract and can accommodate repetitive contraction and relaxation movements of the tract. Array branches have a flexible spring structure, stimulation electrodes, recording electrodes, sensors controlled by a controller and adhesion nodes that fix the branches to the tissue. The electrode array can sense the normal peristalsis from upstream tissue and produce a stimulus signal to stimulate the incapable intestine section to generate stimulation-induced contractions. Electrodes on the incapable intestine section can be used for stimulation or recording, the recorded signal from the incapable intestine section can be sent back to the electronics to form a closed loop control system.

The fixation mechanism may instead include an elongated flexible body that passes through the distal tip anchor and is attached to the fixed body. Tension applied to the elongated body creates a releasing motion of the distal tip anchor to free the distal tip anchor from the features of the fixed body.

  • Patent number: 10035014
    Abstract: An implantable medical lead has a torsional stiffness and is rotationally coupled to a stylet. Applying rotation directly to the lead in turn causes rotation of the stylet. Where the stylet has a bent tip for purposes of steering the lead, the rotation applied to the lead rotates the bent tip so that the lead can be steered by rotating the lead rather than rotating a hub of the stylet. The rotational coupling may be achieved through one or more features provided for the lead and/or the stylet, such as a feature within a lumen of the lead that mates to a feature along the stylet or a feature of the stylet hub that engages the proximal end of the lead. The torsional stiffness of the lead may be provided by adding a feature within the lead body, such as a braided metal wire or an overlapping foil.

  • Patent number: 9855419
    Abstract: Selective sensing implantable medical leads include pulsing and sensing portions and pulsing and not sensing portion. Leads and electrodes may be used in defibrillation and as integrated bipolar defibrillation electrodes. An entire electrode can pass charge while a valve metal or valve metal oxide portion of the electrode prevents the entire electrode from sensing, effectively rejecting unwanted signals. Differential conduction pathways, due to the valve metal and/or oxides thereof, cause the portions of the electrodes to conduct differently when used anodically and cathodically. Complex intracardiac electrical gradient can be formed along with a number of virtual electrodes within the tissue. Reentrant loops can thereby be pinned following defibrillation shock.

  • Patent number: 9439723
    Abstract: A device and method for inserting a variable stiffness catheter into a subject with a catheter body being in relatively stiff state at a first temperature and a more flexible state at a second temperature. A temperature sensitive polymer is incorporated into the catheter that varies in stiffness depending on the temperature. The stiffness of the catheter is regulated by being in thermal contact with a circulating fluid within the catheter, or by being connected to resistive members in thermal contact with temperature sensitive alloys or polymers. The variable stiffness catheter can therefore be guided through the vasculature while in a relatively flexible state, but be changed into a relative stiff state during ablation procedures.

  • Patent number: 9254377
    Abstract: A multilayer helical wave filter having a primary resonance at a selected RF diagnostic or therapeutic frequency or frequency range, includes an elongated conductor forming at least a portion of an implantable medical lead. The elongated conductor includes a first helically wound segment having at least one planar surface, a first end and a second end, which forms a first inductive component, and a second helically wound segment having at least one planar surface, a first end and a second end, which forms a second inductive element. The first and second helically wound segments are wound in the same longitudinal direction and share a common longitudinal axis. Planar surfaces of the helically wound segments face one another, and a dielectric material is disposed between the facing planar surfaces of the helically wound segments and between adjacent coils of the helically wound segments, thereby forming a capacitance.

  • Patent number: 9220490
    Abstract: A tubular access sleeve and suction tool for accessing an anatomic surface or anatomic space and particularly the pericardium to access pericardial space and the epicardial surface of the heart in a minimally invasive manner are disclosed. A suction tool trunk extending through a suction tool lumen of the sleeve is coupled to suction pads at the ends elongated support arms. The suction pads can be retracted into a sleeve working lumen during advancement of the access sleeve through a passage and deployed from the tubular access sleeve lumen and disposed against the an outer tissue layer. Suction can be applied through suction tool lumens to suction ports of the suction pads that fix to the outer tissue layer so as to tension the outer tissue layer and/or pull the outer tissue layer away from an inner tissue layer so that the anatomic space can be accessed by instruments introduced through the working lumen to penetrate the outer tissue layer.

  • Patent number: 9144678
    Abstract: One aspect of the present disclosure relates to a method for treating body organ aging in a mammal. One step of the method includes identifying at least one target organ in need of a therapy signal. Next, a therapy delivery device is placed into electrical communication with an autonomic nervous system (ANS) nerve target and/or a central nervous system (CNS) nerve target associated with the at least one target organ. The therapy delivery device is then activated to deliver the therapy signal to the ANS nerve target and/or the CNS nerve target in an amount and for a time sufficient to effect a change in sympathetic and/or parasympathetic activity associated with the at least one target organ.

  • Patent number: 9119956
    Abstract: Various embodiments concern an electrode of an implantable medical device for delivering electrical stimulation to tissue. Such an electrode can include a main body formed from a substrate metal comprising one of titanium, stainless steel, a cobalt-chromium alloy, or palladium. The main body may not be radiopaque. The electrode may further include a first coating on at least one side of the main body, the first coating comprising a layer of one of tantalum or iridium metal that is at least about 2 micrometers thick. The first coating can be radiopaque and porous. The porosity of the first coating can increase the electrical performance of the electrode in delivering electrical stimulation to tissue.

  • Patent number: 9117680
    Abstract: A biocompatible, implantable electrode for electrically active medical devices. The implantable medical electrode has a surface geometry which optimizes the electrical performance of the electrode, while mitigating the undesirable effects associated with prior art porous surfaces. The electrode has an optimized surface topography for improved electrical performance. Such a electrode is suitable for devices which may be permanently implanted in the human body as stimulation electrodes, such as pacemakers, or as sensors of medical conditions. Such is achieved by the application of ultrafast high energy pulses to the surface of a solid, monolithic electrode material for the purpose of increasing the surface area and thereby decreasing its after-potential polarization.

  • Patent number: 9107592
    Abstract: An implantable sensor array incorporates active electronic elements to greatly increase the number of sensors and their density that can be simultaneously recorded and activated. The sensors can be of various configurations and types, for example: optical, chemical, temperature, pressure or other sensors including effectors for applying signals to surrounding tissues. The sensors/effectors are arranged on a flexible and stretchable substrate with incorporated active components that allow the effective size, configuration, number and pattern of sensors/effectors to be dynamically changed, as needed, through a wired or wireless means of communication. Active processing allows many channels to be combined either through analog or digital means such that the number of wires exiting the array can be substantially reduced compared to the number of sensors/effectors on the array.
