Abstract
A substance delivery apparatus for a catheter assembly is provided. The delivery apparatus includes a base and a needle connected to the base. The needle is capable of pivotally moving with respect to the base for penetrating into tissues of a passageway for administering a therapeutic or bioactive substance to the subject. The needle can pivot in response to inflation of a balloon incorporated with the catheter assembly.
Claims24
A substance delivery apparatus for a catheter assembly, comprising:
- (a) a base supported by said catheter assembly;
- (b) a needle pivotally connected to said base for penetrating into tissues of a passageway for administering a substance to said passageway;
- (c) a coupling element for pivotally connecting said base to said needle;
- and
- (d) a balloon connected to said base wherein a dilation of said balloon causes said needle to pivot about said coupling element.
2 more elements
A device for delivering a substance to a desired area of a passageway, comprising:
- (a) a catheter assembly having a distal end and a proximal end;
- (b) a membrane having a pair of opposing ends coupled to said distal end of said catheter assembly to form a chamber, said membrane can be inflated from a collapsed configuration to an expanded configuration;
- and
- (c) a first syringe assembly supported by said catheter assembly for allowing a first therapeutic substance to be injected into a tissue of a passageway, wherein said first syringe assembly comprises a base, a needle pivitolly coupled to said base, and a hinge member pivitolly coupling said base to said needle,
- wherein said needle is capable of pivoting from a first position towards a second position in response to said membrane being inflated from said collapsed configuration to said expanded configuration.
2 more elements
A medical assembly, comprising:
- (a) a catheter assembly capable of being guided through anatomical passageways of a subject;
- and
- (b) a selectively inflatable tubular membrane having ends engaged to a distal end of said catheter assembly to define a chamber bounded by said ends of said membrane, wherein said membrane is defined by a first region and a second region, said second region having a wall thickness smaller than a wall thickness of said first region.
