The disclosed technology includes couplers, nose pieces, and strain relief hubs for ablation catheter assemblies and methods of using the same. The disclosed technology can include a medical probe having a coupler having a first portion, a second portion, and a vent port. The second portion can slide between a first position and a second position. When in the first position, the vent port can be at least partially obstructed by the first portion and, when in the second position, the vent port can be unobstructed by the first portion. The medical probe can include a nose piece having an outer diameter of less than 0.14 inches and an aperture extending therethrough. The aperture can be sized to receive a catheter. The medical probe can include a strain relief hub having a first portion and a second portion and configured to be coupled to a handle of the medical probe.

Flexible circuit strips of a catheter balloon may comprise a substrate and a contact electrode disposed on the substrate. A cover may be disposed over a peripheral portion of the contact electrode and an adjacent portion of the substrate The cover is intended to increase robustness of the contact electrode in response to fatigue that might arise from repeated expansion and contraction of the catheter balloon.

Intravascular delivery system for deployment of a therapeutic device, such as a stent, in a controlled and robust manner is supported by a lockable balloon catheter equipped with a locking mechanism configured to lock in vivo to a delivery component, such as a guidewire. The lockable balloon catheter can be controllably transitioned between a locked and an unlocked modes of operation by inflation/deflation of the balloon of the lockable balloon catheter. Being in the locked mode of operation, the lockable balloon catheter facilitates delivery of the therapeutic element along the delivery component to a target site while enhancing the stability of the delivery component, especially near the target site.

Everting balloon systems and methods for using the same are disclosed herein. The systems can be configured to access and dilate body lumen and cavities. For example, the systems can be used to dilate the cervix and access the uterine cavity. The systems can also be used to occlude the cervix. The systems can also be used to occlude the urethra.

A balloon catheter (10) with a shaft (14,24) extending in a longitudinal direction and having a proximal end and a distal end and an inflatable balloon positioned along the shaft. The balloon (12) includes at least one portion connected to the shaft and adapted for moving toward the proximal end thereof when the balloon is inflated. Related aspects are disclosed.

A ureteral catheter includes a drainage lumen having a proximal portion configured to be positioned in at least a portion of a patient's urethra and/or bladder and a distal portion configured to be positioned in a patient's kidney, renal pelvis, and/or in the ureter adjacent to the renal pelvis. The distal portion includes a retention portion for maintaining positioning of the distal portion of the drainage lumen. The retention portion includes a plurality of sections, each section having one or more openings on a sidewall of the retention portion for permitting fluid flow into the drainage lumen. A total area of openings of a first section of the plurality of sections is less than a total area of openings of an adjacent second section of the plurality of sections. The second section is closer to a distal end of the drainage lumen than the first section.

A balloon catheter having a distal-end tip which, even if caught in a stenosis, will not break apart from a distal end of an inner shaft of the balloon catheter when the balloon catheter is forcibly rotated or pulled by an operator. The distal-end tip of the balloon catheter is fixed to the distal end of the inner shaft, and a connecting tube covers an outer surface of the distal end of the inner shaft and a proximal end of the distal-end tip. An inwardly protruding portion of the connecting tube is embedded into the distal-end tip. This creates an anchoring effect and increases a welding area between an outer surface of the distal-end tip and an inner surface of the connecting tube, thereby reducing a risk that the distal-end tip will break apart from the distal end of the inner shaft.

An apparatus includes a shaft, an expandable dilation member, and a bulbous tip. The shaft has a first outer cross-sectional dimension. The dilation member is positioned proximal to the distal end of the shaft. The dilation member is operable to transition between a non-expanded configuration and an expanded configuration. The dilation member is sized to pass through a passageway associated with drainage of a paranasal sinus or a Eustachian tube when the dilation member is in the non-expanded configuration. The bulbous tip is positioned at the distal end of the shaft. The bulbous tip is distal to the dilation member. The bulbous tip has a second outer cross-sectional dimension. The second outer cross-sectional dimension is larger than the first outer cross-sectional dimension. The bulbous tip is removably secured to the distal end of the shaft.

Method and system for treating a patient using an inflatable device. A removal device may be used to remove the inflatable device from the body. The removal device can have at least one manually-actuatable member and at least two opposing jaws at a distal end. At least one of the at least two jaws can be movable by actuation of the at least one manually-actuatable member. At least one of the at least two jaws can have a puncturing member.

The present disclosure provides tubes of the draining of liquid from enterostomies. In accordance with aspects and embodiments, an enterostomy tube is provided for draining liquid stool from the gastrointestinal tract, the enterostomy tube having a flared, internal end with scalloped edges and openings around the circumference to enhance collection and an ovular balloon to better fit within the intestinal tract.
