Abstract
A catheter device is useful in a procedure in which an injectable material or device is injected into a tissue of a patient. In one implementation, for example, the catheter device is useful in injecting a compound into a tissue of the heart, such as the myocardium. The distal tip of the catheter may include an extensible and retractable needle in combination with a camera, a balloon, a vacuum port, or any combination thereof.
Claims14
A delivery catheter comprising:
- a generally elongated tubular body terminating in a distal tip, the distal tip extending along a longitudinal axis and comprising a distal end surface region transverse to the longitudinal axis, and further comprising a ventral surface region, a dorsal surface region, and two lateral surface regions radially disposed from the longitudinal axis;
- a needle lumen extending generally longitudinally through the body and the distal tip, and forming a first opening in the distal end surface region;
- an extensible and retractable needle disposed in the needle lumen, the needle being extensible from the first opening at an angle displaced from the longitudinal axis in a direction toward the ventral surface region and into a predetermined spatial location of tissue treatment;
- a camera lumen extending generally longitudinally through the body and the distal tip, and forming a second opening in the distal end surface region;
- a camera disposed in the camera lumen and configured to have a field of view through the second opening encompassing the predetermined spatial location;
- a balloon lumen extending generally longitudinally through the body and part of the distal tip;
- and
- a balloon coupled to the distal tip and in fluid communication with the balloon lumen, the balloon being deployable to form a dorsal extension portion extending from the dorsal surface region, and two lateral extension portions respectively extending from the lateral surface regions, the lateral extension portions comprising respective surfaces generally coplanar with the ventral surface region of the distal tip.
