Example access devices, treatment devices, and kits useful in performing treatment under magnetic resonance imaging and related methods are described. An example access device includes an elongate tubular member formed of an MRI compatible material and moveable between a first, unexpanded configuration and a second, expanded configuration. The elongate tubular member has a central lengthwise axis, a proximal end, a distal end, an axial length, and a main body that defines a circumferential wall, a lumen, a proximal opening, a distal opening, and a main body opening. The main body opening is arranged in a spiral relative to the lengthwise axis and extends circumferentially along the circumferential wall. The main body opening extends along the entire axial length of the elongate tubular member from the proximal end to the distal end.

Access devices, treatment devices, and kits useful for performing treatment under magnetic resonance imaging and related methods

The disclosure relates to medical devices and methods of assembling medical devices, such as MRI-compatible interventional wireguides. An example of a wireguide includes a series of individual segments, a plurality of connectors, and a plurality of spacers. Each segment in the series of individual segments has a first end and a second end. Each connector of the plurality of connectors joins adjacent segments in the series of individual segments to one another such that a first end of a first segment and a second end of a second segment in the series of individual segments are attached to a connector of the plurality of connectors. A spacer of the plurality of spacers is disposed between each pair of adjacent segments in the series of individual segments. Each of the segments in the series of individual segments is electrically insulated from an adjacent segment in the series of individual segments.

MRI compatible interventional wireguide

The present embodiments provide systems and methods for treating a medical condition. In one embodiment, the system comprises a stent having proximal and distal regions, and further having a delivery state and an expanded state. A therapeutic agent is disposed on a segment of the stent. The stent is disposed around an exterior surface of a core assembly in the delivery state. A coupling assembly releasably secures the proximal region of the stent to the exterior surface of the core assembly. The coupling assembly secures the stent to the core assembly for a predetermined period while the stent is in the expanded state and during release of the therapeutic agent at a target site. The coupling assembly further enables the stent to be disengaged from the core assembly and deployed in a bodily passageway.

Detachable and retrievable stents for therapeutic agent delivery

Among other things, methods and apparatus for inserting devices for closing a tissue opening are disclosed. An anchoring or sealing member has one or more stems and/or filaments that are offset from the center of the member, so that lateral adjustments or movements of the anchoring or sealing member do not uncover the opening, cause the anchoring or sealing member to stick through or pull through the opening. Embodiments including a valve adapted to accommodate a guide wire for addressing emergencies are also disclosed.

Vascular closure with multiple connections

Disclosed herein is a hybrid stent having a balloon-expandable portion joined to a self-expanding portion. The hybrid stent is capable of withstanding the forces applied by delivery. Delivery systems for deploying a hybrid stent are described, as are methods of using such delivery systems.

Hybrid stent and delivery system

Cutting devices useful for cutting objects or materials are described. Examples of cutting devices useful for creating avulsions in animals, such as human beings, are described. A cutting device includes an elongate main body having proximal and distal ends. A first portion of the main body has a cross-sectional shape that substantially lacks flat surfaces and a second portion of the main body has a cross-sectional shape having one, two or more flat surfaces. The distal end defines a hook having one or more sharpened edges disposed within the notch of the hook. Methods of making cutting devices are also described.

Cutting devices and methods

Systems and methods for sealing an opening in a wall within the body of a patient are disclosed. In one embodiment, the system has an elongated body coupled to a vascular closure device and a resisting member, the elongated body having a high resistance portion and a low resistance portion and being constructed and arranged to interface with a resisting member to apply a conforming force to a vascular closure device. In some exemplary embodiments, the elongated body comprises a large diameter portion positioned in a proximal end region of the elongated body. Methods and other embodiments are disclosed.

Vascular closure device suture tension mechanism

A hemostatic valve assembly is disclosed. The assembly comprises a housing having a sidewall that tapers radially inwardly towards the housing distal end. A valve member having an open proximal end and a tapered distal end with an orifice formed therein is disposed within the housing chamber. The valve member is deformable between a closed configuration in which the orifice is substantially closed and an open configuration in which the orifice is open. A biasing member disposed proximal to the valve member is moveable between a longitudinally compressed condition and a longitudinally expanded condition. When in an expanded condition, the biasing member pushes the valve member longitudinally and against the tapered sidewall of the housing. The tapered sidewall of the housing urges the distal end of the valve member radially inwardly, thus urging the orifice to the substantially closed configuration.

Hemostatic valve system

Devices for closing an internal opening, e.g. a hole in a blood vessel, include a shape memory function. Particular substances have been found to provide advantages in use, and in particular forms of closure structures.

Vascular closure with shape memory characteristic

The present disclosure provides, in certain aspects, unique products and methods for abrading or otherwise disrupting an interior surface of a bodily a vessel. In some forms, these products and methods further incorporate the use of one or more occluding members to be deployed in the bodily vessel in and/or around a disrupted vessel region. Abrasive endoluminal devices, in certain embodiments, exhibit a low-profile first condition for delivery into and/or through the vasculature. The device can then be transitioned to a second, expanded condition inside the vasculature for carrying out a desired abrasion. With these types of devices, the manner and design by which the device transitions from a first condition to a second condition can vary. Embodiments of such are disclosed herein.

Devices and methods for modifying veins and other bodily vessels

The present invention relates to methods of making a prosthesis or a stent with a smooth covering. The method includes providing an elastomeric tube including an inner diameter and an outer diameter, positioning the elastomeric tube in a tube expander including a vacuum, expanding the inner diameter and the outer diameters of the elastomeric tube by applying the vacuum, providing a mandrel, positioning an inner covering over the mandrel, positioning a stent over the inner covering, positioning an outer covering over the stent to form a covered stent, positioning the mandrel and the covered stent in the tube expander, releasing the vacuum, removing the elastomeric tube, the covered stent, and the mandrel form the tube expander, applying pressure and heat to the elastomeric tube, the covered stent, and the mandrel, removing the elastomeric tube, the covered stent, and the mandrel from the pressure and the heat, removing the elastomeric tube from the covered stent, and removing the mandrel from the covered stent.

Methods of making a prosthesis with a smooth covering

A catheter is provided with a collection chamber located between a seal and a cap. The seal is located distal from the collection chamber, and the cap is located proximal from the collection chamber. The seal may be opened and closed to alternately allow the passage of material into the collection chamber and prevent fluid from escaping from the shaft lumen. The cap may be opened and closed to allow the removal of a mass from the collection chamber and to prevent fluid from escaping during collection of the mass.

Catheter with a collection chamber

Among other things, there are disclosed apparatuses and methods for medically sealing an opening in a vessel or wall. For example, in medical applications, a delivery tube is provided for insertion through a sheath into a vessel (e.g. a blood vessel). A dome-shaped seal fixed to a filament, an absorbent and/or compressible buffer, and a locking member are provided in the delivery tube. The delivery tube is configured so that it can be inserted into the vessel through a sheath. Tension is maintained on the filament to hold the seal against the tube or sheath. The sheath is pulled out, which pulls out the tube at the same time, leaving the seal over the opening in the vessel wall. The locking member compresses the buffer against the outside of the vessel and with the filament holds the seal in place against the inside of a vessel.
