A method for accessing a blood vessel using a catheter insertion device. The catheter insertion device includes a housing, a needle, a catheter, a guidewire, and a thumbwheel. The thumbwheel is rotatably fastened at a front end of the housing and accessible through an opening in the housing. The guidewire is coupled to the thumbwheel such that an axis of rotation of the thumbwheel is perpendicular to the guidewire and rotation of the thumbwheel advances the guidewire through the lumen of the needle. The method includes preparing the catheter insertion device, inserting a tip of the needle and distal end of the catheter into a blood vessel, advancing the guidewire out of the lumen of the needle into the blood vessel by holding the housing and rotating the thumbwheel, furthering the distal end of the catheter over the guidewire, and removing the needle and the guidewire from the catheter.

Intravenous catheter insertion device and method of use

A method may comprise storing a first waypoint corresponding to a first position of a tip of a steerable medical device including an articulatable segment. The controller may perform a motion pause check operation to determine that an insertion motion of the articulatable segment into a patient anatomy has been paused, while the tip is at a second position. The controller may determine that the articulatable segment has resumed the insertion motion into the patient anatomy. After determining that the articulatable segment has resumed the insertion motion, a second waypoint corresponding to the second position of the tip of the steerable medical device, may be stored. A boundary region may be defined to form a three-dimensional volume enclosing the positions of the stored waypoints. The articulatable segment may be constrained to remain within the boundary region as the articulatable segment is inserted in the patient anatomy.

Method and system for steerable medical device path definition and following during insertion and retraction

A method for controlling an orientation of a steerable distal portion of an elongate instrument, said instrument comprising at least one tensioning member attached to said steerable distal portion may include receiving an input command at a controller for articulation of said steerable distal portion, the articulation correlating to an approximate y-bend and an approximate x-bend of said steerable distal portion; calculating an approximate overall bend from said approximate y-bend and said approximate x-bend; and setting a limit of said approximate overall bend beyond which said steerable distal portion is not permitted to achieve. The method may further include one of: causing actuation of said at least one tensioning member to achieve said y-bend and said x-bend on a condition of said calculated approximate overall bend being equal to or less than said limit, and repeating the receiving, calculating, and setting steps on a condition of said calculated approximate overall bend being greater than said limit.

A prosthetic heart valve delivery catheter includes an embolic filter to provide integrated embolic protection to inhibit the release of emboli into the aorta, the aortic arch or branch vessels, and other vasculature during transvascular heart valve replacement procedures. The embolic filter will usually be fixedly or movably attached to a shaft of the delivery catheter proximal of the prosthetic heart valve.

Catheter with integrated embolic protection device

A medical instrument may comprise a first articulatable segment having a first diameter, and a second articulatable segment having a second diameter smaller than the first diameter, wherein the second articulatable segment is coupled to the first articulatable segment and extends in a distal direction past the first articulatable segment. The instrument may also comprise a first force transmission element coupled to the first articulatable segment and extending in a proximal direction from the first articulatable segment to a first connector portion, the first connector portion being configured to be releasably coupled with a first actuator, and a second force transmission element coupled to the second articulatable segment and extending in a proximal direction from the second articulatable segment to a second connector portion, the second connector portion being configured to be releasably coupled with a second actuator. The first and second force transmission elements may be configured to transmit actuation forces, respectively, to articulate the first and second articulatable segments independently of one another.

Connector device for a controllable instrument

A method for treating a patient using a catheter insertion device. The catheter insertion device includes a housing, a needle, a catheter, a guidewire, and a thumbwheel. The needle extends through the catheter such that a distal end of the needle extends distal of a distal end of the catheter. The guidewire is coupled to the thumbwheel such that rotation of the thumbwheel advances a distal end of the guidewire through a lumen of the needle. The method includes holding the catheter insertion device, inserting the distal end of the needle and catheter into a blood vessel, rotating the thumbwheel to advance the distal end of the guidewire out of the lumen of the needle into the blood vessel, moving the catheter over the guidewire in the blood vessel, and removing the needle and the guidewire from the catheter.

Intravenous catheter insertion device

Devices, methods, and systems for treating an ulcer or skin defect are disclosed. First and second base panels of a closure device are adhered to first and second sides of the ulcer or skin defect, respectively. Lateral ties couple the first and second base panels together and provide a predetermined separation distance or lateral gap between the inner edges of the panel. The predetermined separation distance or lateral gap is sufficient to treat the most common sized ulcers or skin defects, for example, accommodating an ulcer or skin defect with a minor axis of at most 50 mm. The lateral ties have their ends fixed to one panel and their opposite ends adjustably and reversibly attached to the other panel so that the separation distance can be reduced or adjusted to provide a lateral compressive force to the ulcer or skin defect, thereby promoting healing.

Closure apparatuses and methods for ulcers and irregular skin defects

Devices and methods are described for treatment of cardiac arrhythmias, particularly atrial fibrillation. A three-dimensional computer model of the patient's heart produced from imaging data is used to fabricate a personalized or patient-specific customized ablation catheter. The personalized ablation catheter is shaped to fit the unique anatomy of the patient's left atrium and has ablation elements that correspond with each of the patient's pulmonary vein ostia. Ostial fitment elements engage the ostia to align the ablation elements and a base ring attached by spring members urges the ablation elements into apposition with the inner wall of the left atrium. A neuroprotective mesh is attached across the ring to capture and remove potential emboli. Ablation energy, such as radiofrequency energy, is applied through the ablation elements. Electrodes located on the personalized ablation catheter are used to verify electrical isolation of the pulmonary veins at the completion of the procedure.

Personalized atrial fibrillation ablation

A wound or incision closure apparatus comprises a first and second panel. Each of the panels comprises a bottom adhesive layer, a medial substrate layer, and an upper load distribution layer which connect the two panels. A sensory or therapeutic element is disposed adjacent, within, or between two or more of the layers. The sensory or therapeutic element can provide sensing and/or therapy for the incision and/or monitor the incision so that the therapy can be customized and updated.
