摘要: Apparatus and methods for ablation efficacy are described herein where a hood having a deployable elongated feature can extend beyond a distal face of the hood. The elongated feature can channel the energy to the deeper regions within the tissue (such as trabeculated regions or other tissue structures) such that the energy can be delivered to the target tissue despite small or large irregularities in the target tissue surface (or region) and/or changes in the relative distances between the hood and the target tissue.

摘要: The delivery of biological compounds to ischemic and/or infarcted tissue are described herein where such a system may include a deployment catheter and an attached imaging hood deployable into an expanded configuration. In use, the imaging hood is placed against or adjacent to a region of tissue to be imaged in a body lumen that is normally filled with an opaque bodily fluid such as blood. A translucent or transparent fluid, such as saline, can be pumped into the imaging hood until the fluid displaces any blood, thereby leaving a clear region of tissue to be imaged via an imaging element in the deployment catheter. Additionally, any number of therapeutic tools can also be passed through the deployment catheter and into the imaging hood for performing any number of procedures on the tissue for identifying, locating, and/or accessing ischemic and/or infarcted tissue.

摘要: Described herein are devices, systems and methods for treating target tissue in a patient's spine. In general, the methods include the steps of advancing a wire into the patient from a first location, through a neural foramen, and out of the patient from a second location; connecting a tissue modification device to the wire; positioning the tissue modification device through the neural foramen using the wire; modifying target tissue in the spine by moving the tissue modification device against the target tissue; and delivering an agent to modified target tissue, wherein the agent is configured to inhibit blood flow from the modified target tissue. In some embodiments, the step of modifying target tissue comprises removing target tissue located ventral to the superior articular process while avoiding non-target tissue located lateral to the superior articular process.

摘要: In vivo visualization systems are described which facilitate tissue treatment by a user in utilizing real time visualized tissue images with generated three-dimensional models of the tissue region of interest, such as the left atrial chamber of a subject's heart. Directional indicators on the visualized tissue as well as the imaging systems may be utilized while other variations may utilize image rotation or manipulation of visualized tissue regions to facilitate catheter control. Moreover, visualized tissue regions may be combined with imaged tissue regions as well as navigational information to further facilitate tissue treatments.

摘要: Apparatus and methods for rapid deployment of tissue anchors are described herein. A tissue manipulation assembly is pivotably coupled to the distal end of a tubular member and has a lower jaw member and an upper jaw member pivotably coupled to the lower jaw member. A reconfigurable launch tube is pivotably coupled to the upper jaw member and is used to urge the jaw members from a low-profile configuration to an open configuration. A needle assembly can be advanced through the launch tube across tissue received between the jaw members of the tissue manipulation assembly. Tissue anchors can be advanced through the needle assembly for securing received tissue. The tissue anchors can be positioned within a reloadable chamber of a control handle disposed outside the patient, then advanced through the needle assembly.

摘要: Needle assemblies for tissue manipulation are described herein. In creating tissue folds within the body of a patient, a tissue manipulation assembly may generally have an elongate tubular member, an engagement member slidably disposed through the tubular member and a distal end adapted to engage tissue via a helical member, tissue stabilizing members positioned at the tubular member distal end which are adapted to stabilize tissue therebetween, and a delivery tube pivotable about the tissue stabilizer. A needle deployment assembly is deployable through the tissue manipulation assembly via a handle assembly, through the tubular member, and into or through tissue. An elongate pusher is translationally disposed within a sheath of the needle deployment assembly and can be urged distally for deploying an anchor assembly from the sheath distal end. The anchor assembly is positioned distally of the pusher within the sheath.
