Implantable Electrical Leads and Associated Delivery and Control Systems

An electrical lead for implantation in a patient is disclosed. The electrical lead can include a distal portion configured to split apart into sub-portions that travel in multiple directions during implantation into the patient and an electrode extension that increases a distance between an electrode and one or more other electrodes on the distal portion of the lead and/or facilitates contact of the electrode with patient tissue.

Cardiovascular access and device delivery system
11653948 · 2023-05-23 · ·

A system and method of accessing a heart of a patient is provided. A cardiac access channel is established through an apical wall of the heart to provide direct access through the apical wall to the left ventricle. A vascular access channel is established through the skin to a peripheral blood vessel. A first end of an elongate member is advanced from the outside of the apical wall through the cardiac access channel and into the left ventricle. A second end disposed opposite the first end remains outside the patient. The elongate member is drawn into and through the vascular access channel to externalize the first end of the elongate member while leaving the second end outside the apical wall of the heart.

Umbilical splint and method of use
11464664 · 2022-10-11 · ·

A use of an umbilical splint for shaping an umbilicus after an abdominal operation is described. The umbilical splint may comprise an insertion portion extending in a longitudinal direction and terminating at an insertion end for insertion into the umbilicus. Furthermore, the insertion portion may comprise a bulbous section near the insertion end. The bulbous section may be operable to apply pressure to a tissue of the umbilicus after the abdominal operation. The insertion portion may have different cross-sectional shapes including circular and oval. Finally, the insertion portion may be configured to engage the umbilicus such that the umbilical splint is retained within the umbilicus.

PERCUTANEOUS WOUND BARRIER
20230113181 · 2023-04-13 · ·

A surface-modified cannula includes a hollow shaft having a proximal opening and one or more surface features along a portion of the length of the hollow shaft, the one or more surface features including one or more channels, one or more depressions, and/or two or more ports each extending at least partially between an outer diameter and an inner diameter of the hollow shaft. The one or more surface features are configured to enable, upon delivery of the cannula to a position proximate to a wound site in the blood vessel, collection of the patient’s blood from the wound site, and ejection of the blood along an access path to the wound site, thereby enabling blood to migrate from the wound site to a region surrounding and extending from the wound site along the access path.

DEVICES AND METHODS FOR ACCESSING THE INTRADURAL COMPARTMENT AND TREATING INTRACRANIAL HEMATOMA

Devices and methods are described for a minimally invasive procedure offering immediate relief of brain compression and prevention of subdural hematoma re-accumulation. For example, this disclosure describes devices and methods for embolization of bleeding branch vessels of the middle meningeal artery and subdural hematoma drainage in a single endovascular intervention using multimodal catheter-based technology.

Methods and Systems for Controlling Cooperative Surgical Instruments with Variable Surgical Site Access Trajectories

Systems, devices, and methods for controlling cooperative surgical instruments with variable surgical site access trajectories are provided. Various aspects of the present disclosure provide for coordinated operation of surgical instruments accessing a common surgical site from different approach and/or separate body cavities to achieve a common surgical purpose. For example, various methods, devices, and systems disclosed herein can enable the coordinated treatment of tissue by disparate minimally invasive surgical systems that approach the tissue from varying anatomical spaces and must operate differently, but in concert with one another, to effect a desired surgical treatment.

First responder device
11622755 · 2023-04-11 · ·

A first responder device for treating blood flow from a deep wound or a bodily cavity having an inflatable balloon, a first chamber accommodating a liquid arranged for inflating the balloon, a second chamber accommodating a cooling agent capable of dissolving in the liquid when coming in contact therewith, thereby lowering the temperature, a rupturable seal between the first and second chambers, and a structure for forcing the liquid out of the first chamber into the inflatable balloon, and for rupturing the rupturable seal.

APPARATUS AND METHOD FOR SEALING A VASCULAR PUNCTURE

A closure system for delivering a sealant to an arteriotomy. A distal section of the closure system can include overlapping inner and outer sleeves that can expand with expansion of the sealant. A proximal section of the closure system can include a handle portion and a sheath adapter extending from the handle portion. The handle portion can comprise one or more actuators that when depressed or engaged can assist in deployment of the sealant in the arteriotomy and can further include tamping of the sealant and/or retraction of an expandable member. The sheath adapter can removably engage a side port or an irrigation line of a standard procedural sheath. When the sheath adapter is secured to the procedural sheath, movement of the closure system can also move the procedural sheath.

DEVICES AND METHODS FOR EXCLUDING THE LEFT ATRIAL APPENDAGE

Devices and methods are described for occluding the left atrial appendage (LAA). The device excludes the LAA from blood flow to prevent blood from clotting within the LAA and subsequently embolizing, particularly in patients with atrial fibrillation. The implantable device is delivered via transcatheter delivery into the LAA and secured within the LAA. The implant comprises an expandable and compliant frame and an expandable and conformable tubular foam body. The device may have a thromboresistant cover at a proximal end. The frame may have recapture struts inclining radially outwardly from a central hub. The frame may have axially extending side wall struts, with adjacent pairs of side wall struts joined at one or more apexes. Anchors extend from the frame and into the foam to engage tissue.

Drive-Enhanceable Handheld Elongate Medical Device Advancer and Related Systems, Devices and Methods

A drive-enhanceable handheld advancer is provided for advancing an elongate device through a pathway defined in an advancer body that includes a rotatable manual thumbwheel partially embedded in the body for receiving a user-exerted manual control movement from a thumb, and a manual drive having a nip, a transmission, and a reverse clutch. The transmission operatively connects the thumbwheel to the nip for driving advancement, and the reverse clutch maintains a first interference grip connection between the nip and the elongate device. The manual control thumbwheel can move inward responsive to user-applied grip movements to increase grip with the elongate device. The reverse clutch applies augmented force from grip movements to the nip for increasing the grip drive connection, which can be applied at a different angle from the inward movements. The reverse clutch can include slotted pivot supports for the thumbwheel and drive rollers on the advancer body.
