Abstract
Methods and apparatus are provided for treating tissue with apparatus that includes an priming portion for initiating a healing response in the tissue to be treated, and which delivers a bioactive agent during or after preparing tissue adjacent the apparatus, as by generating or aiding a healing, regeneration or repair response in the tissue. The priming portion may comprise an abrasive surface, fluid ejection ports, and/or stimulation by electrical, thermal, or light energy.
Claims21
A method of delivering cells to a therapeutic location, comprising:
- inserting a surgical needle through tissue, the needle having a needle shaft, a tip region, a needle tip, and a priming portion adjacent to said needle tip arranged to prepare tissue adjacent to said tip region at the therapeutic location;
- operating said priming portion to prepare adjacent tissue at the therapeutic location;
- and
- releasing a plurality of cells from said tip region of said needle so as to deliver cells toward the prepared tissue.
A cell delivery system, comprising:
- an elongated needle body comprising a first portion along a longitudinal axis and a second portion along the longitudinal axis, the body terminating in a distal tip adapted for tissue penetration;
- said first portion and second portion capable of transition from a first configuration for insertion into tissue to a second configuration for delivery of cells when a portion of said body is adjacent a tissue location where therapy is desired;
- and
- said first and second portions defining a first cavity adapted to hold a plurality of cells when said needle body is in said first configuration, wherein when said needle body is in said second configuration, said first cavity is open for allowing delivery of a plurality of cells toward a tissue location where therapy is desired.
A cell delivery system, comprising:
- an elongated body comprising a priming portion, a cell-carrying portion, and terminating at a tissue-penetrating portion;
- said tissue-penetrating portion arranged to penetrate tissue as the tissue-penetrating portion is forced into tissue;
- said priming portion positioned adjacent to said tissue-penetrating portion and arranged to generate a healing or regeneration response in tissue adjacent to said priming portion when said priming portion is adjacent a tissue location desired for therapy;
- and
- said cell-carrying portion arranged to deliver a plurality of cells to tissue adjacent to said elongated body.
A method of delivering cells, comprising:
- inserting a surgical needle with a needle shaft and a tip region into tissue of a human body;
- operating said surgical needle to generate a healing or regeneration response in at least a portion of the tissue additional to any effect caused by the inserting;
- and
- releasing a plurality of cells from said tip region of said needle so as to deliver cells toward the tissue portion.
