A medical apparatus includes a guidewire and a fixator catheter. The fixator catheter comprises a tubular body with a distal portion and a proximal portion, and further includes a distal opening, a fixator secured to the distal portion, and a body opening arranged between the fixator and the proximal portion. The guidewire passes through the body opening and the distal opening of the fixator catheter. The fixator is movable between a compact configuration and an expanded configuration and, in the expanded condition, is capable of anchoring the guidewire and fixator catheter in a lumen of a blood vessel.

The present disclosure is directed to a device. The device may include a distal shaft defining a central lumen and an orienting element comprising at least one inflatable member. Wherein a first portion of the orienting element extending from the shaft in a first direction and a second portion of the orienting element extending from the shaft in a second direction. Further, wherein the second direction is substantially opposite the first direction.

A lead delivery apparatus and a method of delivering a medical lead to an anatomic target site. The method includes inserting a hydraulic plug into an internal delivery lumen of a delivery shaft, and coupling a medical lead to the hydraulic plug. Hydraulic pressure is applied to the hydraulic plug through the delivery lumen, thereby moving the hydraulic plug toward an anatomic target site, and advancing the medical lead toward the target site.

Devices and methods are described for occluding the left atrial appendage (LAA) to exclude the LAA from blood flow to prevent blood from clotting within the LAA and subsequently embolizing, particularly in patients with atrial fibrillation. A foam implant is delivered via transcatheter delivery into the LAA and anchored using an internal locking system of the implant. The locking system includes deployable anchors that can be deployed after deployment of the foam implant from the delivery catheter and expansion of the foam within the LAA. The implant location can thus be verified before deploying the anchors to secure the implant. The locking system can be reversible to allow retraction of the anchors and repositioning or retrieval of the implant.

The present invention provides a catheter for treating occlusions in blood vessels. An exemplary catheter for treating occlusions in blood vessels comprises a tubular inner member including a base segment with a first lumen defining a fluid inlet port, and a second lumen defining a fluid outlet port. An extension segment is distal to the base segment. The extension segment has a reduced cross-section. An emitter assembly includes a first insulated wire extending through the second lumen and a second insulated wire, and a conductive sheath wrapped circumferentially around the first insulated wire, the second insulated wire, and the extension segment. A cap or balloon is sealably attached to the distal end of the catheter and surrounds the emitter assembly, said cap or balloon being fillable with conductive fluid.

Devices and methods are described for occluding the left atrial appendage (LAA) to exclude the LAA from blood flow to prevent blood from clotting within the LAA and subsequently embolizing, particularly in patients with atrial fibrillation. An implant is delivered via transcatheter delivery into the LAA. The implant includes a conformable structure comprising a foam body and internal support. The support includes anchors that penetrate the foam body and anchor the implant to the walls of the LAA. The implant provides compliance such that it conforms to the native configuration of the LAA.

A connecting device is provided for connecting a pipe or tube-shaped element to the heart or a blood vessel of a patient, comprising a suture ring that has an opening, which can be closed by means of a closure element and through which said pipe or tube-shaped element is guided in the axial direction. The closure element is secured to the suture ring by means of at least one elastic securing element. A radially-expandable sealing element can also be provided in order to establish a sealing placement of the closure element against the suture ring.

An intravascular device for providing feedback to an operator during use and methods of providing the same as disclosed. A catheter tube extends from a handle assembly. An expandable portion is connected to the catheter tube and is selectively movable between a first position and an expanded position. A feedback device provided at the expandable portion provides the operator with the feedback.

The present invention relates to inflatable devices such as coronary and peripheral angioplasty devices, which can achieve better expansion of blockages in various types of blood vessels, and expansion of other cardiac and non-chambers and/or channels in the body. Further, the present invention can also be used in other inflatable devices that can be used to open other blockages in cardiology, urology, gastrointestinal, biliary ducts, non-medical blockages, etc. present invention provides a shaped inflatable apparatus, system, and/or device for treating pathological narrowing of and/or expansion of blockages in fluid-carrying conduits such as blood vessels in a body of an animal, the inflatable apparatus, system, and/or device comprises an inflatable chamber, wherein the inflatable chamber provides for better expansion of blockages in various types of blood vessels, and expansion of other cardiac and non-chambers and/or channels in the body, wherein the inflatable chamber is a non-cylindrical shape or non-circular in cross-section.

An apparatus includes a shaft, and a guide coupled and angularly deflectable relative to the shaft via a guide coupler. The guide is configured to be transitioned between a delivery configuration and a deployed configuration in which a distal end of the guide points away from a centerline of the shaft. The apparatus further includes an elongate member slidably disposable within a guide lumen and extendable distally relative to the distal end of the guide. The elongate member defines a lumen. A puncture member is slidably disposable elongate member lumen and configured to extend distally relative to a distal end of the elongate member. The puncture member defines a lumen configured to receive a guide wire, and has a first internal diameter at a distal end portion thereof and a second internal diameter, greater than the first internal diameter, in a portion proximal to the distal end portion.
