Apparatus for delivering a device to a hollow organ

An apparatus for delivery of a device into a hollow organ and a method of delivery are provided. The apparatus includes an elongated tube having proximal and distal openings and being configured for carrying the device on a distal portion thereof. The apparatus further includes a tubular cover for covering at least a portion of the device when mounted on the elongated tube, the tubular cover being radially elastic and axially non-elastic. The tubular cover is retrievable into the elongated tube through the distal opening, such that when the device is mounted on the elongated tube and covered by the tubular cover, retrieval of the tubular cover into the elongated tube uncovers the device for delivery into the hollow organ.

SYSTEMS AND METHODS FOR SELECTIVELY OCCLUDING THE SUPERIOR VENA CAVA FOR TREATING HEART CONDITIONS
20220401718 · 2022-12-22 · ·

Systems and methods are provided for treating conditions such as heart failure and/or pulmonary hypertension by at least partially occluding flow through the superior vena cava for an interval spanning multiple cardiac cycles. A catheter with an occlusion device is provided along with a controller that actuates a drive mechanism to provide at least partial occlusion of the patient's superior vena cava, which reduces cardiac filling pressures, and induces a favorable shift in the patient's Frank-Starling curve towards healthy heart functionality and improved cardiac performance. The system may include sensors to determine the degree of occlusion of the superior vena cava. The occlusion system may be used to reduce volume in a heart and facilitate a cardiac procedure. The occlusion system may be used to relieve an overloaded chamber during and/or after deploying a VAD.

DEVICES, SYSTEMS, AND METHODS FOR BLOOD FLOW CONTROL

Methods for performing endovascular procedures are described herein. The methods may comprise advancing an expandable member of a blood flow control device to a target location in a blood vessel of a patient, and rotating a circular gear positioned at least partially within a housing of a controller via the controller communicably coupled to the blood flow control device. Rotating the circular gear may translate a linear gear of a syringe pump fluidly coupled to the expandable member thereby adjusting a volume of the expandable member. Various blood flow control devices, control systems, and fluid delivery systems are also described herein. The fluid delivery systems may include a pump configured for manual or automated delivery of fluids, or configured to switch between automated and manual modes of delivery. The pump may be a syringe pump that utilizes a rack and pinion system, a motor, and a sensor to track the position and/or movement of a component of the syringe pump during fluid transfer. Alternatively, the pump may be a pressure differential pump that includes a flow restrictor and a pressure sensor that controls delivery of fluid from a fluid reservoir. Systems and methods including the syringe and pressure differential pumps are also described.

The devices generally include a wire having shape memory properties and a flexible membranous material disposed about the wire. Some embodiments include a lateral fringe on the membranous material. Some embodiments include a fluid capture cup affixed to the wire.

Flow control valve

The present disclosure relates generally to the field of medical devices and establishing fluid communication between body lumens. In particular, the present disclosure relates to devices and methods for establishing a controlled flow or access passage between body lumens.

Methods and devices for transcervical treatment of endometrial cancer and hyperplasia

An infusion catheter includes a housing, a proximal shaft assembly, a first distal shaft assembly and a second distal shaft assembly. The housing has one or more inflation ports and one or more infusion ports. The proximal shaft assembly supports a first balloon. The first distal shaft assembly extends distally from the proximal shaft assembly and supports a first distal balloon. The second distal shaft assembly extends distally from the proximal shaft assembly and supports a second distal balloon. The first and second distal shaft assemblies define infusion openings in fluid communication with the one or more infusion ports. The infusion catheter may be inserted into a uterine cavity to occlude tubal ostia and an internal cervical OS of the uterine cavity for sealing the uterine cavity. A therapeutic agent may be delivered through the infusion catheter and into the sealed uterine cavity to treat the uterine cavity.

Methods and devices for fallopian tube diagnostics

Methods and devices for performing minimally invasive procedures useful for Fallopian tube diagnostics are disclosed. In at least one embodiment, the proximal os of the Fallopian tube is accessed via an intrauterine approach; an introducer catheter is advanced to cannulate and form a fluid tight seal with the proximal os of the Fallopian tube; a second catheter inside the introducer catheter is provided to track the length of the Fallopian tube and out into the abdominal cavity; a balloon at the end of the second catheter is inflated and the second catheter is retracted until the balloon seals the distal os of the Fallopian tube; irrigation is performed substantially over the length of the Fallopian tube; and the irrigation fluid is recovered for cytology or cell analysis.

Sealed neurovascular extendable catheter

A catheter is provided which includes an outer catheter and an extendable inner catheter. A sealing feature is positioned between the inner catheter and the outer catheter to seal the annular gap between the two while allowing axial translation. The seal may be a compliant protrusion surrounding the inner catheter and may have a chevron-shape for facilitating axial translation. The seal may be a one-way valve configured to allow antegrade flushing but prevent retrograde flow. The seal may be squeegee-like flange on the distal tip of the outer catheter. The seal may be an expandable bulge, which may be mechanically expandable or inflatable or which may be a photosensitive or electrosensitive hydrogel. The seal may include a spring that is radially compressed upon translation or rotation of the inner catheter to transiently break the seal. Also provided is a seal for sealing between the catheter and the vasculature.

SYSTEMS AND METHODS FOR TRANSCATHETER AORTIC VALVE TREATMENT

Devices and methods are configured to allow transcarotid or subclavian access via the common carotid artery to the native aortic valve, and implantation of a prosthetic aortic valve into the heart.
